LOGIC CONTROL PUSHBUTTONS OPEN, CLOSE, STOP
Open, Close and Stop buttons are mounted directly on the logic
board. Thus, making it easy to program as well as have door
control at the electrical box. Either the stop control or a jumper
must be wired between terminals 4 and 5 for the on board push
buttons to function.
NOTE: Refer to logic board illustration on page 15 for all
component locations. Before programming the logic board, set
the operators open and close limits. LEDs on the logic board are
provided to assist setting the limits. As each limit is activated the
corresponding LED will light up. The abbreviations are Open Limit
Switch (OLS), Close Limit Switch (CLS) and Sensing Limit Switch
(SLS). Refer to page 8 for limit switch adjustment instructions.
