Pro-lock maintenance
Procedure
1
Check that the locks are properly secured, clean, dry
and corrosion free.
2
Check that the beaks and keepers are secure, clean, dry
and in good condition.
3
Check the locks for wear and verify smooth operation.
4
Check that the lock contacts are clean and properly
fixed.
5
Clean the contacts using a lint-free cloth only; do not
use abrasives.
6
Check that the lock contact breaks before the door is
mechanically unlocked.
a. There is a locking tab at the bottom of the lock
plunger (see Figure 1) that prevents the contacts
from mating unless the beak lifts the locking tab.
b. To check this, push the center lock plunger in with a
pencil ensuring the lock contacts DO NOT touch.
NOTE
: NEVER grease or lubricate the locking tab.
c. If the contacts do touch with the center plunger
pushed in, then you need to repair or replace the
lock.
7
Check the lock wiring, switches and solenoids for
mechanical damage, security of terminations or signs of
excessive heating.
8
Verify that rattling the doors during motion does not
stop the lift.
9
Check that the additional door closed microswitch
above the door is properly secured, clean, dry and in
good condition.
Pro-lock adjustment
Procedure
1
There are three ways to adjust the lock contacts as
noted below.
No other adjustment is authorized or
allowed.
a. There are three nuts holding the lock in place.
Loosen these nuts to move the lock closer to or
farther from the door.
b. The receiver has two bolts holding it in place on the
receiver plate. Loosen these bolts and move the
receiver to the best position.
c. To attain more swipe on the contacts, the receiver
plate can be shimmed out from the door using 1/4”
flat washers.
