the resistance of the sensor, place a thermocouple
on the suction line at the exit of the freezing
cylinder. Compare temperature and sensor
resistance with the table as reference. If measured
value does not coincide with a value on the table
(± 400 ohms), replace the sensor.
NOTE:
If the right control panel shows an E12, make sure
the storage setting is set to NONE.
Error Code 13 - Right Hopper Sensor
The Right Hopper Sensor Error (E13) indicates a
failure of the hopper sensor or an extreme out of
range condition (< -34°F or > 99°F). If the control
panel displays an E13, turn the right Freezing
Cylinder Off-On switch Off and back On. If the
control panel still displays the error condition
code, refer to the machine's wiring diagram and
the Temperature Sensor Chart (Figure 11). Check
each lead of the sensor to ground for continuity. If
continuity is found, replace the sensor. To check
the resistance of the sensor, place a thermocouple
on the suction line at the exit of the freezing
cylinder. Compare temperature and sensor
resistance with the table as reference. If measured
value does not coincide with a value on the table
(± 400 ohms), replace the sensor.
NOTE:
If the right control panel shows an E13, make sure
the storage setting is set to NONE.
COMMO TIMEOUT Error
A COMMO TIMEOUT Error indicates a
communication interruption between the display
and the control board. This error can be caused by
a poor connection or a faulty phone cable.
Disconnect and reconnect the telephone cable at
the control board. If the error does not clear,
disconnect and reconnect the telephone cable at
the display panel module. If the error still appears,
the cable may be faulty or the display panel
module may be faulty.
Alternating Flashing Control Panel Lights
On machines with a Main Power Switch, when
this switch is placed in the ON position and the
Freezing Cylinder OFF/ON switch is in the OFF
position, the green and amber display panel lights
will flash in alternating sequence. This indicates
that the storage cabinet or hopper is being
refrigerated, but the left freezing cylinder is not
receiving power. Placing the Freezing Cylinder
OFF/ON switch in the ON position will return the
freezing cylinder to the SLEEP mode. Pressing
the PUSH TO FREEZE button will begin the
freezing cycle.
The display panel lights will also flash in an alternating
sequence under any error codes. Clear the error
and place the Freezing Cylinder Off-On switch in
the Off position and back in the On position.
7.3 SERVICING TIP
Prevent Compressor from Running During Servicing
When servicing the machine, set the Refriger setting
on the left IntelliTec control from 2 Hopper to None
(Refer to Section 3.3). This will prevent the
compressor from running. When service work has
been completed, change the Refriger setting back
to its previous value.
