ADJUSTMENT OF LIMIT SWITCHES
1.
Turn on the main power supply. Confirm that the correct
line voltage is at terminals L1, L2 and L3,
Figure 14.
2.
Make sure that fuses F1, F2, F3, and F4 are installed,
Figure 14.
3.
Turn the power to the door on using the disconnect switch
located on the front of the control box. Verify that the PLC
is in the run mode.
4.
Check PLC input 1, door close limit switch. This should be
turned on. If this is not on, check the close limit switch to
make sure that it is in alignment with the magnet on the
limit switch pulley.
5.
Momentarily press the green OPEN button and observe
the door. If the door jogs downward, lockout and tag the
main electrical power and reverse the motor leads at
terminals V and W,
Figure 14.
Reconnect the power and
verify the correct door movement.
6.
If the door jogs upwards, continue jogging until the door
reaches the OPEN limit switch.
7.
Continue to jog the door by momentarily pressing the
OPEN button, the door will now move downward toward
the closed position. Continue until the door reaches the
CLOSE limit switch, approximately 4" off the floor.
NOTE:
In the “jog” mode, when the door reaches the
CLOSED limit switch, it will reverse direction.
If the door reaches the 4" measurement and does not
reach the Closed limit switch, turn off power to the
door and adjust the Closed limit switch,
Figure 13.
8.
Continue to jog the door until it is fully open.
