7 ALARMS LIST

Note: Faults probes

Once the sensor is replaced, the alarm di-

sappears after 10 seconds. The sensor alarms at -50°C are disa-
bled during freezing at -18°C and during the ice cream
hardening function. Where not specified, each alarm is accom-
panied by a buzzer (if present). The sound made is a five second
beep that is repeated every 15 seconds. The label indicating the
alarm in progress is alternately displayed with the current display.

ALL

Er1

Cell sensor failure

Cause:

Outside of operating range
(-50°C / +100°C) for more than 30 seconds with a
blast chilling temperature cycle in progress.

Effect:

In standby it prevents startup of blast chilling/
freezing.
In blast chilling/freezing and storage, the cycle is
not blocked and the compressor is activated in cy-
cles (according to the parameters)

Reset:

check connections and operation of the
cell sensor

ALL

Er2

Evaporator Sensor Failure

(only if evaporator sensor is enabled)

Cause:

Outside of operating range
(-50°C / +100°C) for more than 30 seconds with a
blast chilling temperature cycle in progress.

Effect:

In standby, blast chilling/freezing
and storage, there is no effect.
Any defrost will end due to a timeout.

Reset:

check connections and operation of the evapora-
tor sensor

ALL

Er3

Product Probe Failure

Cause:

Outside of operating range
(-50°C / +100°C) for more than 30 seconds with a
blast chilling temperature cycle in progress.

Effect:

In standby it prevents startup of temperature con-
trolled blast chilling/freezing. In temperature con-
trolled blast chilling/freezing it causes a change
over to a timed cycle. In storage, there is no effect.

the blast chilling settings. The buzzer sounds every
3 seconds

Reset:

To silence the alarm, press the

button.

ALL

Temperature Alarm

Cause:

The blast chiller doesn't reach the set temperature in
the time expected during blast chilling/freezing

mode, the display shows the alarm followed by
the temperature, and the buzzer sounds for 3 se-
conds and then repeats after a minute

ALL

High Temperature Alarm

Cause:
