1. Entrance Door Switch Plate
& Proximity Switches
1.1. Installation
1. Install the switch into the front plate of the
door operator in reverse of removal.
1.2. Proximity Switch Adjustment
Adjust the distance between the switch
and the teeter plate to ensure correct actuation
of the entrance door. Ensure the following
conditions are met prior to
proceeding with adjustments:
❒ Using a digital multimeter (DMM), verify
each proximity switch is receiving power
and ground.
❒ Open the hinged access panel above the
entrance door and operate the emergency
release control to exhaust air from the door
system.
1. Manually move door panels to the fully
closed position and ensure output lever is
rotated fully clockwise (as viewed from the
bottom looking up.
2. Use a feeler gauge to measure gap
between teeter lever and bottom of the
LS1 proximity switch. Loosen switch lock
nuts as required and adjust switch to
obtain a gap of 0.080 ± 0.010 inches (2.00
± 0.13 mm) (Dim “A”). See “Fig. 1: Proximity
Switch Adjustment (Door Closed).” on
page 2.
3. Manually open the door and ensure the
output shaft is rotated fully counter-clockwise
as viewed from the bottom looking up.
The LS2 proximity switch should actuate
just prior to the door being fully opened,
and remain actuated with the door fully
open, illuminating the LED light at the rear
of the switch. This actuation point is
referred to as 85° open.
4. Use a feeler gauge to measure gap
between teeter lever and bottom of the
LS2 proximity switch. Loosen switch lock
nuts as required and adjust switch to
obtain a gap of 0.080 ± 0.010 inches
(2.00±0.13 mm) Dimensions in Fig 1
applies to LS2
5. Manually close the door and ensure the
output shaft is rotated fully clockwise as
viewed from the bottom looking up. The
LS1 proximity switch should actuate just
prior to the door being fully closed, and
remain actuated with the door fully closed,
illuminating the LED light at the rear of the
switch. This actuation point is referred to
as 5° closed.
6. Manually operate the door mechanism
several times between fully open and fully
closed to ensure proper actuation of the
switches.
7. Torque switch lock nuts to 130 in-lb.
8. Close the emergency release control to
apply system air pressure to door motor.
9. Cycle door controller several times
between open and closed to ensure proper
operation of the door mechanism and limit
switches.

2.2. Proximity Switch Adjustment
Adjust the distance between the switch
and the output lever to ensure correct actuation
of the entrance door. Ensure the following
conditions are met prior to
proceeding with adjustments:
❒ Using a digital multimeter (DMM), verify
each proximity switch is receiving power
and ground.
❒ Open the exit door emergency valve cover
and operate the emergency release control
to exhaust air from the door system.
1. Manually close the exit door to rotate the
output lever fully clockwise to the closed
position. Position the 5° (lower) proximity
switch so that the head of the proximity
switch is centered over the flat of the output
lever and install lock nut.
2. Adjust proximity switch in or out as
required to obtain a 0.080 ± 0.010 inches
(2.00±0.13 mm) (Dim. “A”) gap between
the end of the switch and the flat of the output
lever. See “Fig. 2: Proximity Switch
Adjustment – Door Closed” on page 3.
3. Manually open the exit door to rotate the
output lever fully counter-clock-wise to the
open position. Position the 85° (upper) limit
switch so that the head of the proximity
switch is centered over the flat of the output
lever and install lock nut.
4. Adjust proximity switch in or out as
required to obtain a 0.080 ± 0.010 inches
(2.00 ± 0.13 mm) gap between the end of
the switch and the flat of the output lever.
The Dimensions in Fig 2 also applies to the
door open proximity switch.
5. Manually operate the door mechanism
several times between fully open and fully
closed to ensure proper actuation of the
switches.
6. Torque switch lock nuts to 130 in-lb.
7. Close the emergency release control to
apply system air pressure to door motor.
8. Cycle door controller several times
between open and closed to ensure proper
operation of the door mechanism and limit
switches.
