PROGRAMMING INSTRUCTIONS 
Once the operator is installed or if the control board is replaced, you will need to program the control 
board for proper current sensing. The operator should be functional and the open and close limits 
set. 
 
1.  Push and hold the LED ENABLE button for five seconds. 
 
 The 
STOP” LED will blink indicating the board is in 
 learn 
mode. 
 
2. Cycle the gate three full times (must reach the open and 
close limit switches on each cycle
). 
 
 The 
STOP” LED will now stay illuminated. 
 
3. Adjust the current sensitivity pot to insure safe operation  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The current sensitivity may be readjusted at any time without relearning the board. 
 
Periodically check the current sensitivity for safe operation. 
The 835/836  circuit boards incorporate a safety feature that will put the operator into a hard shut-
down mode if the circuit board detects a current sense two consecutive times during a cycle. This 
hard shutdown condition can only be reset by shorting the FIREBOX or UL connectors on the left 
side of the circuit board to ground. If a firebox is used in the installation, The firebox door should 
be opened and closed to reset the circuit board.
