Solenoid draws 16 A inrush current from PS873.
Solenoid must be wired to a PS873 logic board:
}
If 871-2 logic board, refer
to Von Duprin instructions
941352.
If other 873 logic board,
refer to Von Duprin
instructions 941356.

Troubleshooting solenoid operation
If the solenoid fails to retract the latch bolt when power is applied, recheck wiring for
proper connections.
If solenoid retracts latch bolt momentarily but will not remain in energized position:
1. Check wiring for proper connections, guage, and distances.
2. Check for latch bolt binding caused by improper strike installation, warped door, etc.

EL ADJUSTMENT PROCEDURE
A. Check for proper function:
1. Make sure device is not dogged.
2. Depress pushbar and make sure latch bolts
retracts and extends fully (see Figure 3).
3. Electrically energize solenoid and hold.
4. Check latch bolt(s) for full retraction (must
clear strike (see Figure 3).
5. Release solenoid and check latch bolt
extension (see Figure 3).
6. Continue to Section B if device does not
function electrically.
B. Determine if dogging rod adjustment is too long or short:
1. The dogging rod adjustment is too long if latch bolt
does not retract and clear strike (see Section C for
adjustment).
2. The dogging rod adjustment is too short if latch bolt
does not fully extend or latch bolt fully retracts but
solenoid releases while energized (see Section D for
adjustment).
C. Adjust solenoid if dogging rod is too long (see Figure 4):
1. Remove end cap c and dogging cover d.
2. Loosen cap screw e.
3. Hold plunger g depressed in solenoid housing h.
Note: Push hard against plunger g to overcome
an internal spring in solenoid housing h.
4. Turned threaded bushing f in to shorten dogging
rod i so latch bolt fully retracts.
5. Tighten cap screw e.
Note: Cap screw e must be tightened against
flat on threaded bushing f. Apply a few
drops of Loc-Tite 222 to threads of cap
screw e.
6. Replace dogging cover d and end cap c.
7. Return to Section A to check for proper function.
