5. SYSTEM TEST
5.1. With the door closed, set the 3-position switch, if used, to AUTO and turn on all AC power.
For applications using companion door, try to get both doors to open same amount of
degrees before hitting hard stop (either internal gearbox stop or rubber bumper on wall).
5.2. Activate the operator using an activation device. The operator should perform one
sizing cycle.
Sizing Cycle: Occurs when the door is activated for the first time after power is
turned on. During the sizing cycle, the door opens and closes once.
If the door sizes properly, go to step No. 5.3.
If the door does not open at all during the sizing cycle:
• Check that the 3-position switch, if used, is not set to OFF.
• Check door for binds and proper mechanical installation.
• Verify that all safety sensors are inactive.
• If an electromechanical lock is used, check that the lock disengages before
the operator opens the door.
• Verify that the Breakaway switch, if used, is connected to NC contacts. If a
Breakaway switch is not used, check that the Breakaway cable coming from
the control box logic board is jumpered (jumper part No. 81269).
• Check fuse, wiring, and connections.
• Adjust the operator as follows and check door operation:
Opening speed: ................. 01
Back check speed: ............ 01 for one door, 02 for two doors
Hold open delay: ................ 05
Back check position: ......... 75
Latch position: ................... 10
Close speed: ..................... medium
Electric lock: ...................... SA (fail safe) or SE (fail secure) to match lock
If the door does not open fully during the sizing cycle, check door for binds,
obstructions, or items that could activate safety sensors.
WARNING !
KEEP HANDS, CLOTHING, WIRES, TOOLS, LADDERS, ETC. AWAY
FROM THE DOOR WHEN THE OPERATOR IS INITIALLY TURNED ON.
If control box does not operate as expected during system test, see section
6 for troubleshooting tips.
