| IMPORTANT NOTICES Vehicular gate systems provide convenience to their users and limit vehicular traffic onto your property. These systems can produce high levels of force, therefore it is important that you are aware of possible hazards associated with your gate operating system. These hazards may include pinch points, entrapment, absence of controlled pedestrian access or traffic backup. Be sure that the installer has instructed you on the proper operation of the gate and gate operator system. Be sure that the installer has trained you about the basic functions of the reversing systems associated with your gate operating system and how to test them. These include reversing loops, inherent reversing system, and may include electric edges, photo electric cells, or other external devices. This Owner's Manual is your property. Keep it in a safe place for future reference. * The speed limit for vehicular traffic through the gate area is 5 MPH. Install speed bumps and signs to keep vehicular traffic from speeding through the gate area. Failure to adhere to posted speed limits can result in damage to the gate, gate operator, and to the vehicle. * Be sure that all residents are familiar with the proper use of the gate and gate operator. Be sure that all residents are familiar with the possible hazards associated with the gate system. * Be sure that all warning signs are permanently installed on both sides of the gate in an area where they are fully visible to traffic. * It is your responsibility to periodically check all reversing devices. If any of these devices are observed to function improperly, remove the operator from service immediately and contact your installing or servicing dealer. * Follow the recommended maintenance schedule. * Do not allow children to play in the area of the operator or to play with any gate operating device. * Be sure that all activating devices are installed a minimum distance of 10 feet away from the gate and gate operator, or in such a way that a person cannot touch the gate or gate operator while using the activating device. If activating devices are installed in violation of these restrictions, immediately remove the gate operator from service and contact your installing dealer. * To remove the gate operator from service, operate the gate to the full open position and then shut off power to the gate operator at the service panel. |

| INSTALL THE GATE OPERATOR ONLY WHEN: * The operator is appropriate for the construction of the gate and usage Class of the gate. * All openings of a horizontal slide gate are guarded or screened from the bottom of the gate to a minimum of 4 feet (1.2 m) above the ground to prevent a 2-1/4 inch (57.15 mm) diameter sphere from passing through the openings anywhere in the gate, and in that portion of the adjacent fence that the gate covers in the open position. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
 |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| * All exposed pinch points are eliminated or
guarded. * Guarding is provided for exposed rollers. * This operator is intended for installation only on slide gates used to control vehicular traffic. Pedestrians must be provided with a separate access opening. * The gate must be installed in a location so that sufficient clearance is provided between the gate and adjacent structures when opening and closing to reduce the risk of entrapment. Sliding gates should not open into public access areas. * The gate must be properly installed and work freely in both directions prior to the installation of the gate operator. Do not over-tighten the operator clutch to compensate for a damaged gate. * Controls must be far enough from the gate so that the user is prevented f rom coming in contact with the gate while operating the controls. Controls intended to be used to reset an operator after 2 sequential activations of the entrapment protection device or devices must be located in the line-of-sight of the gate. Outdoor or easily accessible controls should have a security feature to prevent unauthorized use. * All warning signs and placards must be installed where visible in the area of the gate. |

| PRIMARY ENTRAPMENT PROTECTION This vehicular gate operator is equipped with an inherent (Type A) entrapment sensing system. This system will sense an obstruction in both the opening and closing gate cycles, and will cause the gate to reverse direction should an obstruction be encountered. If the system detects a second obstruction before reaching the full open or close limit after the initial reversal, an alarm will activate and the operator will require a reset before resuming normal operation. See Section 4 for more information. SECONDARY ENTRAPMENT PROTECTION Non-contact and contact sensors can be used individually or in combination with each other to provide secondary entrapment protection. For gate operators utilizing a non-contact sensor: 1 . See instructions in this manual on the placement of non-contact sensors. 2. Care should be exercised to reduce the risk of nuisance tripping, such as when a vehicle trips the sensor while the gate is still moving, and 3. One or more non-contact sensors shall be located where the risk of entrapment or obstruction exists, such as the perimeter reachable by a moving gate or barrier |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| For gate operators utilizing a contact
sensor: 1 . One or more contact sensors shall be located at the leading edge, trailing edge, and post mounted both inside and outside of a vehicular horizontal slide gate. 2. A hardwired contact sensor shall be located and its wiring arranged so that the communication between the sensor and the gate operator is not subjected to mechanical damage. 3. A wireless contact sensor such as one that transmits radio frequency (RF) signals to the gate operator for entrapment protection functions shall be located where the transmission of the signals are not obstructed or impeded by building structures, natural landscaping or similar obstruction. A wireless contact sensor shall function under the intended end-use conditions. |

SECTION 1.8 WARNING SIGN
INSTALLATION This DoorKing slide gate operator is shipped with two warning signs. The purpose of the warning signs is to alert uniformed persons, and to remind persons familiar with the system, that a potential hazard may exist so that appropriate action can be taken to avoid the hazard or to reduce exposure to the hazard. 1 . Permanently install the supplied warning signs on each side of the gate in locations so that the signs are visible by persons on both sides of the gate. 2. Use appropriate hardware such as wood or metal screws (not supplied) to install the warnings. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| ELECTRICAL / WIRING Before attempting to connect any wiring to the operator, be sure that the circuit breaker in the electrical panel is in the OFF position. Permanent wiring must be installed to the operator as required by local electrical codes. it is recommended that such work be performed by a licensed electrical contractor. Since building codes vary from city to city, we highly recommend that you check with your local building department prior to installing any permanent wiring to be sure that all wiring to the operator (both high and low voltage) complies with local code requirements. THIS GATE OPERATOR MUST BE PROPERLY GROUNDED!! SECTION 2.1 CONDUITS |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| The conduit requirements shown in figure 2.1
are for a typical slide gate operator installation (the slave operator is
shown for those applications where a slave operator may be used). The
conduit requirements for your application may vary from this depending on
your specific needs. Use only sweeps for conduit bends. Do not use 900 connectors as this will make wire pulls very difficult and can cause damage to wire insulation. We suggest that minimum 3/4 inch conduit be used. Be sure that all conduits are installed in accordance with local codes. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| SECTION 2.2 HIGH VOLTAGE Use the chart below to determine high voltage wire size requirements. The distance shown in the chart is measured in feet from the operator to the power source. If power wiring is greater than the maximum distance shown, it is recommended that a service feeder be installed. When large gauge wire is used, a separate junction box must be installed for the operator connection. The wire table is based on stranded copper wire. Wire run calculations are based on a 110 VAC power source with a 3% voltage drop on the power line, plus an additional 10% reduction in distance to allow for other losses in the system. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Route incoming high voltage power through
conduit and into the operator as shown in figure 2.2A. Be sure wiring is installed in accordance with local codes. Be sure to color code all wiring. Connect the power wires to the high voltage terminal strip as shown in figure 2.2B. It is recommended that a surge suppressor be installed on the high voltage power lines to help protect the operator and circuit board from surges and power fluctuations. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| SECTION 2.3 CONTROL WIRING Controls must be far enough from the gate so that the user is prevented from coming in contact with the gate while operating the controls. Outdoor or easily accessible controls should have a security feature to prevent unauthorized use. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 2.3.1 STANDARD CONTROL WIRING Connect optional control devices to the operator terminal strip as shown in figure 2.3.1. Be sure that all electrical connections are made in accordance with local electrical codes. Use 18 AWG wire for all low voltage wiring, maximum distance 3000 feet. Use a low voltage surge suppressor DoorKing P/N 1878-010 if low voltage wire runs exceed 1000 feet. All inputs to the terminal strip must be NORMALLY OPEN. Standard reversing input (term 6) only functions while the gate is in the closing cycle and should not be used as an input for a secondary entrapment protection device. See Section 2.4 for secondary entrapment protection device wiring. Do not Dower any devices from the circuit board other than a low voltage radio receiver as shown in 2.3. |

| SECTION 2.4 SECONDARY ENTRAPMENT PROTECTION DEVICE WIRING Secondary entrapment protection devices must be installed to insure a safe operating environment and to reduce the risk of entrapment. This operator has inputs for non-contact sensors and contact sensors for both opening and closing gate cycles. Secondary entrapment protection may be provided by a combination of both type sensors. See Section 5.3 for a list of acceptable secondary entrapment protection devices. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 2.4.1 NON-CONTACT SENSORS Disconnect power to the gate operator before installing the non-contact sensors. See figure 2.4.1 for suggested placement of sensors. (Diagram is for illustration purposes only. Actual placement of sensors is dependent on the installation requirements). One or more non-contact sensors shall be located where the risk of entrapment or obstruction exist, such as the perimeter reachable by a moving gate or barrier. Use only UL listed (or equivalent) non-contact sensors. Connect the non-contact sensors as shown below to the auxiliary terminal strip located on the 4702 control board. Note that the common for these devices is connected to Main Terminal 12. |

Connect the contact sensors as shown below to the auxiliary terminal strip located on the 4702 control board. Note that the common for these devices is connected to Main Terminal 12. Contact sensors must be located at the leading edge, trailing edge, and post mounted both inside and outside of the vehicular sliding gate. Additional contact sensors may be added for additional protection where an entrapment zone may exist. Hardwired contact sensors must be located and wiring arranged so that the communication between the sensor and the gate operator is not subjected to mechanical damage. |

| SECTION 2.6 MASTER / SLAVE CONTROL WIRING 2.6.1 STANDARD OPERATORS The interface wiring between the two operators requires three (3) 18 AWG wires for control plus two (2) additional 18 AWG wires for secondary entrapment protection device connection. Each operator must be connected to it's own power source as described in section 2.2. IMPORTANT!! Plug-in loop detectors cannot be used in master/ slave applications with these operators. Use external detectors that have a normally open (N.O.) dry contact relay as a signal device. 1 . Connect the master / slave wiring (terminals 8, 9, 12) as shown in figure 2.8.1. Be sure that power to both operators is OFF. 2. Connect the common (C) and normally open (N.O.) relay contacts from the OPEN loop detector to terminals 8 and 12. 4. Connect the radio receiver as shown in figure 2.3.1. Note that the relay contact from the radio receiver connects to terminal 8. 5. Connect any other OPEN devices to terminals 8 and 12. Connect standard external REVERSING devices to terminals 9 arid 12. See section 2.8.2 for secondary entrapment protection device wiring for master / slave operators. |

| 2.6.2 SECONDARY ENTRAPMENT DEVICE INSTALLATION AND WIRING FOR MASTER / SLAVE OPERATORS Secondary entrapment protection for slide gate operators connected in a master/ slave configuration will require three sets of photo-beams to insure protection. One photo-beam is directed across the roadway and connected to the CLOSE photo-beam input on the auxiliary terminal strip of both the master and slave operator. This photo-beam is active in the close direction only and will not affect the movement of the gates while the gates are opening. Two photo-beams are required to protect the open direction of the gates - one for the master operator and one for the slave operator. These photo-beams are connected to the OPEN photo-beam input on the auxiliary terminal strip in their respective operator. These photo-beams are active in the open direction only. If a beam is interrupted while the gate(s) are in the open cycle, only the gate that is controlled by the interrupted beam will stop, the other gate will continue in the open direction. |

| SECTION 2.9 AUXILIARY TERMINAL IDENTIFICATION AND DESCRIPTION The auxiliary terminal is located on the 4702 circuit board just to the right of main terminals 4 and 5. Auxiliary terminals are numbered 1 through 5 with the first terminal at the top. 1. OPEN PHOTO-BEAM This input is only active when the gate is in the opening cycle. An open photo-beam input during the opening cycle will cause the gate to stop. The gate will remain stopped until the photo-beam input is cleared, at which time the gate will resume the open cycle. 2. CLOSE PHOTO-BEAM This input is only active when the gate is in the closing cycle. A close photo-beam input during the closing cycle will cause the gate to stop. The gate will- remain stopped until the photo-beam input is cleared, at which time the gate will resume the close cycle. 3. OPEN EDGE This input is only active when the gate is in the opening cycle. An open edge input during the opening cycle will cause the gate to stop and then reverse. a. If the the gate reaches the full closed position, the gate will remain closed, ignore any maintained inputs and enter a soft shutdown condition NOTE: If the gate was initially activated by a time clock with a contact closure across the gate operator open input, this input will be ignored until another input (open loop, reverse loop. etc.) is received by the gate operator. b. If a close edge sensor is activated prior to the gate reaching the full closed position, the gate will stop and enter a soft shutdown condition. 4. CLOSE EDGE This input is only active when the gate is in the closing cycle. A close edge input during the closing cycle will cause the gate to stop and then reverse. a. If the gate reaches the full open position, the timer will automatically close the gate (if it is turned on). Once the gate starts to close again, if the close edge input is activated a second time prior to the gate reaching the full closed position, the operator will stop and reverse and will enter a soft shutdown condition. b. If an open edge sensor is activated prior to the gate reaching the full open position, the gate will stop and enter a soft shutdown condition. 5. ALARM RESET This input turns off the entrapment alarm and resets the operator after a hard shutdown has occurred. 6. ALARM SIGNAL This is an output from the circuit board that drives the entrapment alarm. Do not connect any other device to this terminal.

| ADJUSTMENTS The switch settings and adjustments in this chapter should be made after your installation and wiring to the operator(s) is complete. Whenever any of the programming switches on the circuit board are changed, power must be shut-off, and then turned back on for the new setting to take effect. SECTION 3.1 CIRCUIT BOARD ADJUSTMENTS * Set the DIP switches on the circuit board to the desired setting. See switch setting chart in section 3.2. * Auto close timer (when turned on) can be set from 1 second (full counter clockwise) to approximately 23 seconds (full clockwise). * Dry contact relay contacts (terminals 10-11) can be set for Normally Open (NO) or Normally Closed (NC) operation by placing the relay shorting bar on the NO or NC pins respectively. * Power LED indicates that low voltage power is applied to the circuit board. The input LEDs should be OFF and will only illuminate when the input is activated. The pulse LEDs will blink as the operator is running. They can be either ON or OFF when the operator is stopped. |

| SECTION 3.2 SWITCH
SETTINGS The DIP switches located on the circuit board are used to program the operator to operate in various modes and to turn on or off various operating features. Typical switch settings are labeled (Typ). Whenever a switch setting is changed, power must be turned OFF to the operator, and then turned back on for the new setting to take affect. Check and review ALL switch settings prior to applying power to the operator. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Switch 1: Sets direction of the operator so
that the operator cycles open upon initial power up and open command. If the
operator begins to cycle close upon initial power up and open command, turn
power off and change the setting on this switch. Switch 2: Turns the auto close timer on or off. Maximum time that the close timer can be set for is 23 seconds. Switch 3: This switch determines when the relay on the board will be activated. This relay can be used as a switch for various functions such as illuminating a warning light when the gate is not closed, or turning on a green light when the gate is full open. Switch 4: This switch determines the operation of the solenoid lock and is factory set. CAUTION: Do not change the setting of this switch unless the solenoid / lock assembly has been repositioned for the operation desired. Changing the setting of this switch without physically changing the lock assembly will damage the operator. Switches 5-6: These work in conjunction with each other and determine if the operator will stop the gate at the full open position, or if the gate should stop 1, 2 or 3 inches short of the full open position. Switches 7-8: These work in conjunction with each other and determine if the operator will stop the gate at the full closed position, or if the gate should stop 1, 2 or 3 inches short of the full closed position. |

| SECTION 3.3 AUTOMATIC LIMIT ADJUSTMENT This gate operator does not use any mechanical limit switches or run timers to adjust the open and close positions of the gate. The gate open and close positions are determined by the physical stops (or chain stops) of the gate. The gate operator will automatically measure the gate and will set its "limits" from this measurement during this automatic sequence. !! IMPORTANT !! This automatic limit adjustment sequence must be run prior
to testing the operator for normal operation, and prior to testing any of
the safety features that are incorporated into this operator. This includes
the primary and secondary entrapment protection features, and the entrapment
alarm and reset features. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| SECTION 3.4 INHERENT
REVERSE ADJUSTMENT This vehicular gate operator is equipped with an inherent (Type A) entrapment sensing system. This system will sense an obstruction in either the opening or closing gate cycles and will cause the gate to reverse direction should an obstruction be encountered. For this system to function correctly, the gate must be properly installed and work freely in both directions. A good set of ball bearing wheels (or rollers) is essential for proper slide gate operation. 3.4.1 REVERSE SENSITIVITY ADJUSTMENT 1 . Activate the gate operator my momentarily shorting terminal 8 and 12 with a 1 foot piece of 18 AWG wire. Be sure that the automatic limit adjustment has been completed as described in section 3.3. 2. While the gate is running, slowly rotate the reverse sensitivity potentiometer clockwise until the gate reverses travel, then rotate the potentiometer 1/8 turn counter clockwise. Note: Rotating the sensitivity adjustment clockwise INCREASES the reverse sensitivity. Rotating this adjustment counter-clockwise DECREASES the reverse sensitivity. NOTE: After the gate has reversed, the operator will assume a "soft shutdown" making it necessary to initiate the cycle again by momentarily shorting across terminals 8 and 12 as in step 1. 3. Operate the gate a few times to be sure that it cycles completely. 4. Place a 2 x 4 piece of wood in an immobile position along the path of the gate so that the gate will strike it while in the open cycle. The gate must reverse direction after striking the 2 x 4. If it does not, increase the reverse sensitivity by turning the potentiometer 1/8 turn clockwise, then repeat this test. NOTE: After the gate has reversed, the operator will assume a "soft shutdown" making it necessary to initiate the cycle again by momentarily shorting across terminals 8 and 12 as in step 1. 5. Place a 2 x 4 piece of wood in an immobile position along the path of the gate so that the gate will strike it while in the close cycle. The gate must reverse direction after striking the 2 x 4. If it does not, increase the reverse sensitivity by turning the potentiometer 1/8 turn clockwise, then repeat this test. NOTE: After the gate has reversed, the operator will assume a "soft shutdown" making it necessary to initiate the cycle again by momentarily shorting across terminals 8 and 12 as in step 1 to reactivate the automatic close timer. 6. You may have to repeat step 2 several times to find the correct sensitivity adjustment. |

||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 3.4.2 CLUTCH ADJUSTMENT In addition to the reverse sensitivity adjustment, this operator is equipped with a mechanical slip clutch to further reduce the possibility of injury should an entrapment occur. Do not over tighten the clutch in this gate operator to compensate for a damaged or poorly constructed gate, or to compensate for a gate that is too heavy or that has damaged wheels or rollers. Doing this can create a hazard which can result in serious injury or death to persons who may become entrapped. 1 . Be sure power to the operator is turned OFF whenever adjustments to the clutch are being made. Loosen the center hex lock screw to "un-lock" the jamb nut (an allen wrench is provided in the operator), then loosen the jamb nut. You may have to hold the large pulley to loosen this nut. 2. Tighten the jamb nut so that it is finger tight, then tighten it one turn with a wrench. Tighten the center hex lock screw to lock the jamb nut in place. 3. Apply power to the gate operator and cycle it to allow the operator to adjust its limit settings as described in section 3.3. 4. Activate the gate operator by momentarily shorting across terminals 8 and 12 with a 1 foot 18 AWG wire. When the gate begins to open, determine if the clutch is slipping. If the clutch is slipping, turn power OFF and tighten the jamb nut one more turn as described in step 2, then repeat steps 3 and 4 (This process may have to be repeated several times to get the right clutch adjustment). 5. After adjusting the clutch so that the gate opens and closes without it slipping, place a 2 x 4 piece of wood in an immobile position along the path of the gate so that the gate will strike it while in the open cycle. The clutch should slip and the gate must reverse direction after striking the 2 x 4. If it does not, repeat steps 1-3, and 5 to readjust the clutch. NOTE: After the gate has reversed, the operator will assume a "soft shutdown" making it necessary to initiate the cycle again by momentarily shorting across terminals 8 and 12. 6. Place a 2 x 4 in an immobile position along the path of the gate so that the gate will strike it while in the close cycle. The gate must reverse direction after striking the 2 x 4. If it does not, repeat steps 1-3 , and 6 to readjust the clutch. NOTE: After the gate has reversed, the operator will assume a "soft shutdown" making it necessary to initiate the cycle again by momentarily shorting across terminals 8 and 12 to initiate the auto close timer. 7. The ideal clutch adjustment will allow the operator to move the gate through its entire travel cycle without slipping, but will slip upon contact with an obstruction with no more than 75 Lbs of force. This force can be measured with a gate scale, DoorKing P/N 2600-225. |

| Chapter 4 - OPERATING
INFORMATION IMPORTANT SAFETY INSTRUCTIONS WARNING - To reduce the risk of injury or death: 1. READ AND FOLLOW ALL INSTRUCTIONS. 2. Never let children operate or play with gate controls. Keep the remote control away from children. 3. Always keep people and objects away from gate. NO ONE SHOULD CROSS THE PATH OF THE MOVING GATE. 4. Test the operator monthly. The gate MUST reverse on contact with a rigid object or stop or reverse when an object activates the non-contact sensors. After adjusting the force or the limit of travel, retest the gate operator. Failure to adjust and retest the gate operator properly can increase the risk of injury or death. 5. Use the emergency release only when the gate is not moving and power has been shut-off. 6. KEEP GATES PROPERLY MAINTAINED. Read the owner's manual. Have a qualified service person make repairs to gate hardware. 7. The entrance is for vehicles only. Pedestrians must use separate entrance. 8. SAVE THESE INSTRUCTIONS. |

| SECTION 4.2 SHUTDOWN
CONDITIONS Under various entrapment conditions the operator will assume either a soft or hard shutdown (alarm) condition. To determine what type of reset action is required, you will need to understand how the different entrapment conditions affect the gate operator: 4.2.1 SOFT SHUTDOWN This occurs in various situations where the inherent or secondary entrapment protection devices have been activated. In a soft shutdown condition, the operator will not respond to any input that was present when the entrapment protection device sensed an obstruction. If the gate stops at the open position, the operator will not respond to the automatic close timer. * Example 1: A time clock keys the gate open in the morning and an entrapment protection device senses an obstruction prior to the gate reaching the full open position. If the entrapment is sensed by the inherent system, the gate will reverse and run back to the closed position. The time clock input is still present, but the gate will not re-open. NOTE: In some systems, the time clock input comes from the telephone entry system relay. This same relay may also provide open commands for a card reader, MicroPLUS transmitters and the visitor telephone entry. If so, these devices will also be disabled in a soft shutdown condition. * Example 2: If the gate is closing and an entrapment protection device is activated, the gate will either stop or reverse and run back to the open position, depending upon if the secondary or inherent device was activated. The automatic close timer will not close the gate. * Example 3: Vehicle arrives at open loop and gate runs towards the open position. The inherent entrapment protection is activated. The gate reverses and runs back to the closed position. If the vehicle is still present at the open loop a soft shutdown condition does not occur. The loop input provides an immediate reset of the operator and the gate will again run to the open position. 4.2.2 RESETTING A SOFT SHUTDOWN In some conditions, a soft shutdown will reset as soon as the entrapment condition clears. For example, if a non-contact sensor (photo cell) is sensing entrapment, the operator will stop the gate and assume a soft shutdown condition. When the photocell clears, the operator will return to normal operation. When the operator is in a soft shutdown, activation of any "intended input" will reset the operator. An "intended input" includes any command, any standard safety input and any loop input. Activating any of these inputs will reset the gate. At that point the gate will return to normal operation. If the gate is open, the automatic close timer will then time out and close the gate. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 4.2.3 HARD SHUTDOWN A hard shutdown condition occurs when the inherent entrapment protection system has sensed two consecutive obstructions before the gate reaches the full open or closed position. * Example: The gate is closing and the inherent entrapment protection system senses an obstruction and causes the gate to reverse direction. As the gate begins to run in the open direction, a second obstruction is sensed prior to the gate reaching the full open position. Once the second obstruction has been sensed, the operator will stop, the audio alarm will be activated and all standard inputs are shut down (including open commands, safety commands, loop inputs, etc.). NOTE: The audio alarm will remain activated for a maximum of five minutes, or until the operator receives a reset input. The hard shutdown condition will remain in affect even if the audio alarm shuts off after five minutes. 4.2.4 RESETTING A HARD SHUTDOWN When the operator is in a hard shutdown condition, the only way to reset the gate operator and return it to normal operation is to activate the alarm reset input (auxiliary terminal 5 and main terminal12). An alarm reset switch can be mounted external of the gate operator provided that it is installed in the line of sight of the gate and gate operator. NOTE: DoorKing operators have a built-in alarm reset push button mounted on the operator above the power ON-OFF toggle switch. Activating this button will return the gate operator to normal operation, but will not activate the gate operator. Once the gate has been reset, an open or close command is needed to start the gate operator. Most activating commands will cause the gate operator to cycle to the open position. This includes activation of a key switch or open command and activation of an open loop. Activation of a close command will run the gate to the closed position. NOTE: The gate operator will not lose it's limit settings when a hard shutdown occurs. |

| SECTION 4.3 MANUAL /
EMERGENCY VEHICLE GATE OPERATION This operator is equipped with a manual release system that will allow the gate to be pushed open in the event of a power outage or equipment failure. The type of release system may be dependent on local codes, so check with the installer to verify which system your gate operator is equipped with. There are two manual release systems that are available on this gate operator. The standard type release is the FAIL-SAFE system (required by many city codes), while an optional release is the FAIL-SECURE system. NOTE: Never attempt to manually push open any gate with an operator attached to it until you have verified that power to the operator has been shut-off. 4.3.1 EMERGENCY VEHICLE ACCESS CONDITIONS The automatic vehicular gate system must be designed to allow access to emergency vehicles under different operating conditions. 1. During normal powered operation, emergency vehicles access the gate by use of the emergency vehicle access device installed on your gate system. The type of device that is used in your community is dependent on your local city codes. 2. In the event of a power failure, the emergency vehicle access device may not be functional because the gate operator is un-powered. If the gate operator is equipped with a battery back-up system, this system will automatically open the gate when primary (AC) power is removed. NOTE: DC
powered back-up systems are optional and your gate system may or may not be |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 4.3.2 FAIL-SAFE RELEASE The FAIL-SAFE release system is the most reliable and safest method for placing an automated gate in manual operation and is the preferred method of gate release by many Fire Chiefs and Building Inspectors and is typically used in CLASS I and CLASS 11 applications. This system requires no keys, cranks or tools for manual gate operation and is completely automatic. This prevents any delays for emergency vehicle access in the event that a power outage has occurred. * When AC power is removed (power failure or switch power off), the operator "FAILS" in a "SAFE" condition allowing the gate to be manually pushed open without the need of any tools, keys, cranks or other devices. This assures emergency vehicle access under the worst case conditions. * For manual gate operation, turn power to the operator OFF. If a backup power system is in use, be sure that this power is turned OFF also. Once power is OFF, the gate can be manually operated. * If an attempt is made to force the gate open under normal operating conditions (AC power present), a dead bolt solenoid will automatically engage in the gate operator to lock the gate. If Gate Trackers reporting is in use, a forced entry attempt transaction will be sent to the DoorKing access control system at this time. 4.3.3 FAIL-SECURE RELEASE The FAIL-SECURE option locks the gate when primary (AC) power is removed and requires a keyed release to place the gate in manual operation. The FAIL-SECURE option is typically used in CLASS III and CLASS IV applications. * Be sure that primary (AC) and backup (DC) power is removed or shut-off prior to placing the gate operator in manual operation. * Insert the manual release key into the keyed release on the side of the gate operator, and turn it clockwise 1/4 turn. The gate can now be manually operated. |

| Chapter 5 MAINTENANCE, TROUBLE SHOOTING AND ACCESSORIES Inspection and service of this gate operator by a qualified technician should be performed anytime a malfunction is observed or suspected. High cycle usage may require more frequent service checks. SECTION 5.1 MAINTENANCE When servicing the gate operator, always check any secondary (external) reversing devices (loops, photo eyes, reversing edges, etc.) for proper operation. If external reversing devices cannot be made operable, do not place this operator in service until the malfunction can be identified and corrected. Always check the primary inherent reversing system when performing any maintenance. If the inherent reversing system cannot be made operable, remove this operator from service until the cause of the malfunction is identified and corrected. Keeping this operator in service when the inherent reversing system is malfunctioning creates a hazard for persons which can result in serious injury or death should they became entrapped in the gate. When servicing this gate operator, always turn power OFF!! |

||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| SECTION 5.2 TROUBLE SHOOTING Have a good VOM meter to check voltages and continuity. A Meg-Ohm meter capable of checking up to 500 megohms of resistance is necessary to properly check the integrity of the ground loops. When a malfunction occurs, isolate the problem to one of three areas: 1) the operator, 2) the loop system, 3) the keying devices. Use caution when checking high voltage wiring, the motor capacitor and the motor. 1. Check the input indicator LEDs. They should only come ON when a keying device (card reader, push button, etc.) is activated. If any of the input LEDs are ON continuously, this will cause the gate operator to hold open. Disconnect the keying devices one at a time until the LED goes OFF. 2. Check the secondary entrapment protection devices (photo-cells, reverse edges, etc.). Any short or malfunction in these devices can cause the gate operator to stop or to hold open. Push the RESET button to reset the gate operator. Disconnect the secondary items one at a time until the source of the malfunction is found and corrected. 3. A malfunction in a loop or loop detector can cause the gate operator to hold open, or to not detect a vehicle when it is present over the loop. Pull the loop detector circuit boards from the loop ports on the operator circuit board. If the malfunction persist, the problem is not with the loop system. For more information on trouble shouting loops and loop detectors, refer to your loop detector instruction sheet and to the DoorKing Loop and Loop Detector Information Manual. 4. Check to be sure that there are no shorted or open control wires from the keying devices to the gate operator. If a keying device fails to open the gate, momentarily jumper across terminals 8 and 12 on the gate operator circuit board. If the gate operator starts, this indicates that a problem exist with the keying device and not with the gate operator. 5. Check the high voltage supply. A voltage drop on the supply line (usually caused by using too small supply voltage wires) will cause the operator to malfunction. Refer to the wire size chart in section 2.2. |
