Precision Alarm Switch
The timer is provided with two motors and an
alarm switch which is normally open. Both
motors operate continuously. If one motor
fails, the other motor will continue to drive
the timer; the alarm switch will close, warning
that the timer requires service.
To reset the alarm switch
1. Push gear “A” toward the motor, or lever
“B” will be broken.
2. Using a non-metallic object, depress the
plastic cam until it snaps into position
holding the switch open.
