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

NOTE
When power is applied to the potted circuit
board, the solenoid receives a momentary
signal to retract and a separate signal to hold
as long as power is applied. When attempting
to retract solenoid again, power must be
removed from the circuit and reapplied.

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. Also check adjustment of
vertical rods.

EL (ELECTRIC LATCH RETRACTION)
EL ADJUSTMENT PROCEDURE
A. Check for proper function:
1. Make sure device is not dogged.
2. Depress pushbar and make sure latch bolt(s)
retract and extend 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.
Extended
3/4”
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.

is too short (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.
4. Turn threaded bushing f out to lengthen
dogging rod i so plunger g just bottoms in
solenoid housing h and latch bolt is fully retracted.
Note: Push hard against plunger g to overcome
an internal spring in solenoid housing h.
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.
