A. Voltage at terminals P & N. Should be no less than 11 or more than 16 volts.
B. Check for possible grounds.
C. Check voltage and current during operation.
Voltage should not drop below 11 volts during gate up or gate down cycle.
Power up current should be 6-15 amps. Power down current should be 6-15 amps.
D. Check clearing and descending times.
Clearing time as set per step 16 of 6-10 seconds.
Descending time as set per step 17 of 10-15 seconds.
Clear position with power removed (arm between 70° and 83°).
E. Check terminal board contacts.
Check clearance, square contact and wiping action per page 8.

Install gate arm.
On breakaway pivot type assemblies, install number and type of shear
bolts per arm manufacturers instructions.
d.
Raise arm to vertical
. Install additional counterweights if required and preset them
maximum to field (vertical torque adjustment).
12
.
Set horizontal torque and arm height.
Set horizontal torque to 100 ± 20 foot-pounds at counterweight
side per instructions on page 10.
Note:
The default-up requirement of the model S-40EXIT gate requires
counterweight heavy installation. Set arm height by rotating contact cam #7 and operating gate with down
control. Be sure that horizontal buffer (upper position) is clear of segment gear.
See pages 8 and 9.
13. Raise and check vertical position of arm.
Set the vertical position by rotating contact cam #8 and
operating gate with up control (see page 8).
14. Adjust buffers.
Set both buffers to 1/32 clearance from segment gear per instructions on page 9.
15. Set vertical torque.
With arm horizontal, open test terminal "B." The counterweight heavy arm will move
to a near vertical default position. Adjust the counterweights to obtain a default position between 70
0
and
83
0
. See intructions on pages10 and 11.
16. Adjust clearing time.
Clearing time varies with length of arm but should be between 6 and 10
seconds. Adjust if needed with up speed resistor R1 (lower position item 54 page 18).
17.
Adjust descending time.
Total descent time is a sum of the adjustable snubbing circuit (90°-5°) and the
horizontal snub control through contact #11 (5°-0°).
Adjust the down speed resistor R2 (upper position item
54 page 18) for 10-15 seconds descent time. If faster descent is desired after adjusting, reduce the
horizontal snub travel as follows.
Horizontal snub.
Contact #11 on the terminal board is factory set for approximately 5° full horizontal snub.
This can be reduced to half (2.5°) by rotating the cam if less horizontal snub is desired.
