Control Station

 - Interior station mounts into single-gang electrical box. Provides open and hold open manual operation of the 

gate. P/N 1200-017.

Heater and Fan Assembly

- Use for cold weather climates where temperatures routinely drop below 40°F (4°C). P/N 6550-480

Interconnect Cable

 - Interconnect wire cable contains all the necessary wires to interconnect primary / secondary operators.    

  Cable length 30 feet. P/N 2600-755
  Cable length 40 feet. P/N 2600-756
  Cable length 50 feet. P/N 2600-757

Time Clock

 - 7 day and 365 day time clocks can be used to automatically open gate at pre-set time and days. Compact clock fits 

inside the operator.

  P/N 2600-795 - 365 day clock

Torsion Rods

 - Torsion rod assembly is used on uphill swing gates for counter balance.

 P/N 

1203-084

Hinges

 - Heavy-duty ball bearing hinges provide easy swing gate operation.

  P/N 1200-009, P/N 1200-019, P/N 1200-039.

Surge Devices

 - High and low voltage surge suppressors help prevent circuit board failure caused by lightning strikes and 

power surges. 
  P/N 1876-010 - High Voltage
  P/N 1878-010 - Low Voltage

Gate Scale

 - Use to test torque required to move gate. P/N 2600-225

Speed Bumps

 - Prefabricated six-foot speed bump reduces traffic speed through gate system. P/N 1610-150

7.3 Built-in Diagnostics

This gate operator is designed with built-in diagnostics that will alert you to potential or existing problems that the microproces-
sor has detected.  Specific fault conditions are checked and the operator will signal that a fault exist through the built-in alarm.

Constant tone is heard when power is applied:

This indicates that the limit switch wire harness is not connected to the circuit 

board.  In this condition, the operator will not run and the tone will continue until the fault is corrected.  Check to be sure that 
the limit switch plug is properly inserted into P2.

Constant tone is heard:

This indicates that the operator is in a hard shutdown condition.  The tone will continue to sound for 

five minutes, and then will beep once every five seconds.  The operator-reset button must be pressed or power must be 
removed and then reapplied to return the operator to normal operation.

Short tone is heard every five seconds:

This indicates that the operator has been in a hard shutdown condition in excess of five 

minutes.  This will continue until the operator-reset button is pressed or until power is removed from the operator.

Operator runs for 1 second and stops, two short tones are heard:

This indicates that there may be a fault with the current 

sensor circuit.  Check that the black current sensor wire has been passed through the hole in the current sensor donut with the 
correct number of loops (1 HP motor - 1 loop).
