1. With the door open, close the switch.
2. Slowly close the door. The door should close fully and without
difficulty (there will be an indication of the interlock operation
just as the door becomes fully closed). If the door closes without
difficulty, the interlock catch is adjusted properly for closing. If
the door will not close due to interference, the door interlock
catch is out of adjustment and must be readjusted. The door
interlock catch is a small bracket mounted on the inside of the
door and held on by two screws. To adjust, loosen the screws
and slide the door interlock catch downward a small amount,
until the door can be closed. Retighten the two screws. Torque
to 7.4 Nm (55 lb.-in.).
3. With the BPS in the ON position and the door closed, attempt to
open the door (do not use force or jerk the door). The door
interlock should prevent the door from opening (the door will
open only a slight crack). If the door is prevented from opening,
the interlock catch is adjusted properly. If the door can be
opened, the door interlock catch must be readjusted. To adjust
the catch, angle similar to step 2 above, but slightly slide the
door catch upward until the door is prevented from opening.
Inspection after Installation
Refer to the CENTERLINE 2100 Low Voltage Motor Control Centers
Instruction Manual, publication 2100-IN012, supplied with the MCC.
Look specifically at the sections entitled, “Final Checklist before
Energizing” and “Energizing Equipment.” The remote power source(s)
to the motor control center may be reconnected and the BPS can be
placed into service.
Inspect the BPS and the installation. Points of inspection should
include the following:
•
Terminal guard assembly has been replaced and the three
terminal guard screws have been tightened.
•
All connector hardware has been tightened to the required
torque specifications.
•
BPS terminals are aligned with contact blades.
•
Contact blades mate and close correctly.
•
The arc chutes have not been inadvertently moved and do not
interfere with the operation of the contact blades.
•
Door interlock functions properly.
•
Start-up checks have been performed.
