17.9.35 Failure on sensor E2x.T9 heat transfer fluid in
Function: Activated when the sensor's value indicates a
temperature lower than 0 °C. T9 is calculated according
to the following formula: T9 = T8 - Compressor x 7K +
0.07K x current output in operation.
Reset condition: The value of the sensor indicates >0 °C.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has
disappeared.
17.9.36 Short circuit on sensor E2x.T9 heat transfer
fluid in
Function: Activated when the sensor's value indicates a
temperature higher than 110 °C. T9 is calculated
according to the following formula: T9 = T8 - Compressor
x 7K + 0.07K x current output in operation.
Reset condition: The value of the sensor indicates
< 110 °C.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has
disappeared.
17.9.37 Failure on sensor E2x.T10
Function: Activated when the sensor's resistance value
indicates a temperature lower than -20 °C. In the event
of a failure, T10 is set at a temperature calculated
according to the following formula: T10 = T11 +
Compressor x 3K.
Reset condition: The value of the sensor indicates
> -20 °C.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has
disappeared.
17.9.38 Short circuit on sensor E2x.T10
Function: Activated when the sensor's value indicates a
temperature higher than 40 °C. In the event of a short
circuit, T10 is set at a temperature calculated according
to the following formula: T10 = T11 + Compressor x 3K.
Reset condition: The value of the sensor indicates
< 40 °C.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has
disappeared.
17.9.39 Failure on sensor E2x.T11
Function: Activated when the sensor's value indicates a
temperature lower than -50 °C. In the event of a failure,
T11 is set at a temperature calculated according to the
following formula: T11 = T10 - Compressor x 3K.
Reset condition: The value of the sensor indicates
> -50 °C.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has
disappeared.
17.9.40 Short circuit on sensor E2x.T11
Function: Activated when the sensor's value indicates a
temperature higher than 40 °C. In the event of a short
circuit, T11 is set at a temperature calculated according
to the following formula: T11 = T10 - Compressor x 3K.
Reset condition: The value of the sensor indicates
< 40 °C.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has
disappeared.
17.9.41 High flow temperature E2x.T8
Function: Compressor stops. Activated when the
temperature on sensor T8 exceeds the maximum
permitted temperature for T8.
Reset condition: Restarts when E2x.T9 falls below the
saved temperature with hysteresis on 3K (not
adjustable).
Category: I.
Alarm lamp/buzzer: No.
Restart: Automatic once the alarm cause has
disappeared.
