7.7    LIMIT SWITCHES 

 WARNING

 

TO AVOID THE DANGER OF POSSIBLE DAMAGE TO THE DOOR AND OPERATOR, TRAVELLING CAMS 

MUST BE ADJUSTED TO THEIR APPROXIMATE POSITIONS BEFORE MANUALLY

 

OPERATING THE 

DOOR OR BEFORE APPLYING POWER TO THE OPERATOR.

 

 
 

Only 2 limit switches are used in operators built with an Electronic Control Board. One for the “Open” side 
and one for the “Close” side. No advanced Open or Closed limit switches is used. The microprocessor with 
the built-in logic replaces the advanced Open and Closed limit switches (Figure 18).

 

 

 
 

 

7.8   DESCRIPTION LIMIT SWITCHES 

 

The “Open” limit switch is the end of travel in the open position. Adjust the cam so that the door stops 
in the open position at the desired location. 

 

The “Close” limit switch is the end in the close position. Adjust the cam so that the door stops in the 
closed position at the desired position. 

 
 

 
 
7.9   TROUBLE SHOOTING AN OPERATOR WITH ECB 

Troubleshooting an operator with an ECB is easier since the LEDs provided on the circuit board help to bring 
a better diagnostic while finding the faults.  

 

 

Easy fix 

Check the followings that may prevent the operator from starting 
before coming to any conclusion 

Check light status on 
the ECB 

Before starting any intervention, check the LEDs status and refer to the 
page 17 for a proper diagnostic.  

Check the operating 
modes 

Review the operating modes: B2, C2, D1, T or TS  

Check the 
programming 

A wrong programming on Timer to Close or Mid Stop will stop the door to 
an improper position.  

Check the presence 
of stop jumper 

If the 3 test buttons are being used without the stop jumper between #8 & 
#9, the operator will not respond to the 3 buttons command
