E. ADJUSTING MOTOR MOVEMENT.
For proper operation the motor movement must be synchronized with the power relay C1A and
C1B as well as correct limit switches position.
The filter limit switches is factory set and fastened , but due to transportation, motor limit
sensors can be loosened.

1.1 Set MAIN switch to OFF (0) position.
1.2 Connect the source line supply to the control unit.
1.3 Check existence of 3 phase voltage on the control unit supply inlets, using voltage meter
between TB2 and TB3 (L1 phase) and Between TB3 and TB4 (L2 phase)
1.4 Avoid PLC operation during adjusting motor movement operation by switching down
circuit breaker marked F2.
1.5 Check again that the motor operating voltage connection (triangle/star) is compatible
with line supply voltage applied , and that the overload (OL1) is adjusted according to the
