Wiring Specifications
WARNING: All AC electrical connections must be made by a licensed electrician and observe all national and local electrical codes. Use copper wire only.
AC Power Wiring: Refer to the provided tables for appropriate wire gauge based on voltage, horsepower, and maximum distance. Ensure the supply voltage is adequate and consider voltage drop for longer runs. A separate junction box may be needed for the operator power connection. Ground wire must be properly connected.
DC Control and Accessory Wiring: All control devices use 24 VDC and can be run up to 2000 feet with 14 AWG wire. Control wiring must be in a separate conduit from power wiring. A three-wire shielded conductor cable (Belden 8760) is required for dual operation.
Mounting Pad Installation
The gate operator mounts to posts secured in concrete footings. Posts support the operator and prevent movement. For optional pad mounting, refer to Linear drawing #2700-360.
Gate Preparation: Ensure the gate rolls or slides freely. Cover the gate with fabric with openings no larger than 2-1/4" to a minimum height of 72" above ground level. For picket-style gates, mesh is optional if pickets are spaced less than 2-1/4" apart.
Mounting Specifications: Use two 3-3-1/2” OD galvanized posts secured with concrete footings. Attach the operator using U-bolts and side plates. Ensure the drive chain and gate brackets are assembled correctly, with chain sag not exceeding recommended sizes and not contacting moving parts or the ground.
WARNING: Ensure adequate clearance between the gate and adjacent structures to reduce the risk of entrapment.
Gate Bracket and Chain Assembly
Assemble the gate bracket to the front edge of the gate using U-bolts and hardware. Ensure the bracket is parallel to the gate. Attach the drive chain using a chain pin and master link, unrolling the chain towards the operator. Thread the drive chain under the idler, over the drive sprocket, and under the last idler. Assemble the other gate bracket on the rear edge of the gate. Connect the drive chain to the rear bracket using another chain pin, spring, and master link. Adjust chain tension by tightening jam nuts; approximately 1/4" to 3/8" of slack per foot of drive chain is acceptable. Ensure the chain does not drag on the ground or contact moving parts.
Operator Setup
Controller Access: Remove the plastic dust cover (single phase models) by loosening the wing-screw.
Manual Disconnect: The manual disconnect shifter lever disengages the drive mechanism. Pull the lever to disconnect and push it to the right to re-engage.
AC Power Connection: Connect incoming power to the operator via the power disconnect switch, following wiring specifications. The motor has a thermal overload protector that resets automatically.
Earth Ground: Install an 8-foot copper ground rod next to the operator mounting pad. Connect a solid copper 12 AWG ground wire to the ground rod and the operator's frame. Do not splice the ground wire.
Open and Close Limit Adjustment
The limit nuts are not preset and must be adjusted for each installation. Remove the cardboard filler before adjusting.
Rough Adjustment: With the operator disconnected, manually move the gate to within a foot of its fully open position. Adjust the OPEN limit nut to activate the limit switch. Move the gate to within a foot of fully closed and repeat for the CLOSE limit nut.
Fine Adjustment: Re-engage the operator and turn the power ON. Press the OPEN button and observe the gate. Adjust limit nuts as necessary for fine tuning. If the gate stops during travel, adjust the Open or Close Current Setting or the Maximum Run Timer.
Torque Limiter Adjustments: Ensure the gate moves freely by hand. Adjust the torque limiter tight enough to prevent slipping during normal operation. Loosen the jam nut, turn the adjustment nut clockwise to increase torque, or counterclockwise to decrease torque, then tighten the jam nut.
Controller Features

Programming Keystrokes: Use UP/DOWN to scroll through functions, ENTER to select an option, and ENTER again (hold for 1 second) to change the option. Press UP/DOWN to select the new option, then ENTER to store.
Left or Right Hand Operation: The factory default is right hand. Program for left hand operation if needed.
Dual Gate Enable: Enable for dual gate installations. Wire controllers via COMM LINK terminals. Mid-travel stop is disabled in this mode.
Auto Close Timer: Factory default is OFF. Can be set from 1 to 59 seconds or 1 to 9 minutes. The gate will close automatically after the set delay.
Run Alarm and Pre-start Alarm: Factory default is ON. Beep sounds 3 seconds before operator starts. Options include disabling alarms or setting pre-start alarm duration.
Maximum Open Direction Current Setting: Monitors motor current to detect obstacles. If the programmed load range is exceeded, the operator stops, reverses, and stops again. Adjust to activate reversal with minimal force but allow normal operation.
Maximum Close Direction Current Setting: Similar to open direction, monitors motor current. If the programmed load range is exceeded, the operator stops, reverses to full open, and may lockout.
Advanced Controller Programming
Advanced programming functions are available after enabling Advanced Programming mode.
Maximum Run Time (MRT): Factory default is 99 seconds. Stops the operator if limits are not reached or an obstacle/reversing input is not received before the timer expires. Setting it too close to actual run time can cause premature stops.
Single Button Input Setup: Cycles operator OPEN-STOP-CLOSE-STOP or alternates OPEN/CLOSE. Can be set to OPEN unless fully open, then CLOSE.
Stagger Mode: Used in dual gate installations. Sets one operator for delayed opening and the other for delayed closing.
Stagger Delay Time: Sets the delay duration for Stagger Mode (1-99 seconds).
Auxiliary Relay Mode: Can be set for Maglock, Ticket Dispenser, Strobe, or Alarm functions.
Reverse Delay Time: Sets delay before reversing direction (1-9 seconds). Longer delay for heavier gates.
Brake Delay Time: Sets delay before applying the brake (0-3 seconds). Useful for heavy gates to slow down before stopping.
Constant Pressure Mode: Requires constant pressure on OPEN/CLOSE buttons instead of momentary pressure.
Shadow Loop Open Prevention: Prevents gate from closing if shadow loop is triggered. Can also prevent opening if shadow loop is triggered at close limit.
Reset Cycle Count: Resets the operator's cycle count. Also resets the Maintenance Alert indicator.
Maintenance Alert Trigger: Sets an indicator to light after a programmed number of cycles (5, 10, 15, or 25 thousand).
Mid-travel Stop Position: Allows programming a stop point before full open (1-99 seconds). Disabled in dual gate mode.
Anti-tailgate Enable: If ON, the gate closes immediately after the shadow loop clears. If OFF, Auto Close Timer or CLOSE command is required.
