Do not use an abrupt
BACKCHECK setting, nor expect closer to act as a door stop!
9. FOR 2210DPS: SIGNAL RESPONSE POINT VERIFICATION
Only
If the switch is giving an "open" signal when the door is fully closed, follow steps 9D through 9F.

REMOVE SCREWDRIVER BEFORE ALLOWING DOOR TO MOVE.
Continued:
7D.With closer shaft now stationary, move the end
of the arm to shaft of closer. Slowly move door
so hole in arm lines up correctly with closer
shaft. Push arm up into position and insert
arm shaft screw, as shown in
See below
Use a 3/32” hex wrench to re-adjust MAIN & LATCH speed screws (closed in step 7A). Turn both MAIN
& LATCH speed screws 2 full turns counterclockwise. Open door and observe closing cycle. A normal closing
time from a 90° position is 5 to 7 seconds, equally divided between MAIN & LATCH speeds. If further adjustment
is required, turn regulating screws clockwise to SLOW door speed / counterclockwise to INCREASE door speed.
BACKCHECK is a feature that slows the speed of door at approximately 70°. To INCREASE force turn BACK-
CHECK screw clockwise. To REDUCE force turn BACKCHECK screw counterclockwise.
If door silencers are to be used, they should be installed prior to this step. Close the door slowly and note where
the switch response signal occurs. The factory setting should provide a signal response between 1/4" & 3/4" off
the stop for a 36" door.
if a different signaling point is necessary, perform steps 9A - 9C using a No. 3 Phillips screwdriver (5/16"
shank).
To adjust the signaling point for the door to the closed position:
9A.Open the door approximately 20°, or enough to access the signal adjustment hole in mounting plate
(See , below). Prevent door from moving during the adjustment. Insert the No. 3 Phillips screw-
driver into the signal adjustment hole to engage the trigger gear.
9B.

Check the signal activation point. If still too far from the "door closed" position, repeat steps 9A, 9B & 9C.
