PERATION

The Maintenance Switch (patent no. 5,852,350) consists of a push button switch and operating relay as part of
the relay panel located in the upper left area of the gate cabinet, and a stop bar assembly located at the motor
end of the gear train. See diagram below and on next page.

The Maintenance Switch is applicable to fiberglass/aluminum gate arms up to 32’ long. Activating the normally
open, momentary contact, push button switch will raise up to seven full size counterweight plates* to a hori-
zontal position when the gate arm is removed. Once raised the stop bar is used to hold the counterweights at
horizontal until the arm is in place.

TEPS

1. Close test terminal A (pos. 6) and open test terminal B (pos. 4)
2. Position the Stop Bar with key-slot over the pivot lug in a ready position (see next page).
3. Depress and hold the Push Button until counterweights are fully raised.
4. Rotate the Stop Bar end against the motor pinion teeth and release the Push Button.
5. Install gate arm.
6. Close test terminal B and replace stop bar.
7.   Open test terminal A to raise arm.

Tests show that six of the full size 58# counterweights in a centered position with 13 VDC at gate

terminals can be raised to a full horizontal position.  Five counterweights in a maximum extended
position can be raised to full horizontal with the minimum 11 VDC at gate terminals.

Gates with 7 or more counterweights will require the added use of a come-along or hand cranking
to reach full horizontal position.
