Agitation Timers

The agitation timer is standard equipment for the floor
standing dispenser. The purpose of the timer is to
periodically agitate the ice in the bin to prevent congealing.

TIMER WITH BLINKING LED

The LED tells the technician in which mode the timer is
operating. Rather than a jumper pin, this timer has a female
spade connector that must be connected to terminal
number 6.
• When this jumper is in place, the LED will blink at one-
second intervals. This is the run mode.
• When the jumper is open, the LED will flash every
4/10ths second. This is the test mode and the timer
will cycle every 55 seconds in test mode. Remember
to replace the jumper when testing is complete. If the
timer is left in test mode it will automatically reset to run
mode.
When installing this timer into existing equipment, make sure
to verify correct wiring of the timer. Some older equipment
may require a wiring change. Check the yellow wire from
the ice dispense switch (rocking chute) to the number two
terminal of the timer. With this timer, the yellow wire leaves
the ice dispense switch from the NC terminal of the switch.

The timer is non-adjustable and is set to agitate the ice for
three seconds every three and one half-hours. Activating the
dispenser will reset the timer. After 3.5 hours of non-use the
timer will energize the dispenser motor.
To check for correct function of the agitation timer, use the
following procedure:
The agitation timer is located at the front of the dispenser in
the control box, on the left side of the ice chute.
1. Remove the jumper between the two pins.
2. The timer will cycle every 55 seconds.
3. If the timer does not cycle every 55 seconds, replace the
timer.
4. Replace jumper after testing.

Never operate with jumper removed. Damage will occur.
