EVERSING THE SOLENOID WHEN CHANGING THE FUNCTION
To change an electrically-locked function mortise lock to the
corresponding electrically-unlocked function, or to change an
electrically-unlocked function to the corresponding electrically-locked
function, you must flip the solenoid.
To flip the solenoid for mortise locks, perform the following steps.
1. Remove the mortise case. See Removing components for IDH Max
Mortise Locks on page 4–3 or Removing components for electrified
mortise locks on page 4–26 .
2. Remove the mortise case cover and spacer. See
Task A. To remove
the mortise case cover and case spacer: on page 4–43 .
3. Grasp the locking bar and rotate it. The solenoid plunger rotates
with it.
4. Remove the locking bar from the solenoid pin.
5. Flip the solenoid and insert the pin of the solenoid plunger into the
hole on the locking bar.
Note: For IDH Max Locks, the solenoid rests in an opening in the
case and is held in place by the case cover. For electrified locks, the
solenoid has two feet that fit into two small holes in the case. When
the feet are inserted properly, the solenoid is held in position.
6. Rotate the solenoid and locking bar into place. See Figure 4.49 .
7. Make sure that the solenoid wires or cable is not pinched.
8. Reinstall the mortise case cover and case spacer. See Task H. To
reinstall the mortise case cover and case spacer: on page 4–48 .
9. Reinstall the mortise case. See
Reinstalling components for
IDH Max Mortise Locks
on page 4–13 or
Reinstalling components
for electrified mortise locks
