[f] SURGE ABSORBER
The Surge Absorber is provided to protect
the Controller Board from lightning.
[g] CAPACITOR - XY FILTER
The Capacitor - XY Filter is provided to
prevent the Controller Board from signal
errors caused by internal and external
noises.
[h] BIN CONTROL SWITCH
The Bin Control Switch is composed of a Proximity
Switch and Actuator. When the Chute fills up, ice will
push up the Actuator on top of the Chute to switch off
the Proximity Switch. After 7 seconds, the Controller
Board will stop the Gear Motor and Compressor at the
same time. When ice is used, the Actuator will return to
the original position to switch on the Proximity Switch.
The Gear Motor will restart in 7 seconds, and the
Compressor in 5 minutes.
When the Bin Control Switch seems to have
malfunctioned, check the dimensions of the Actuator
as well as the operation of the Proximity Switch. Also,
if the Chute Switch or the Gear Motor Circuit Protector
has operated for some unidentified reason, be sure to
check the Actuator for proper dimensions.
1) Remove the Bin Control Switch from the Chute.
2) Move the Actuator to the maximum operation angle
as shown below (top). Check that the Actuator is
about 13 mm away from the Barrier. If not, replace
the whole Bin Control Switch assembly.
