43 01 3 Temperature sensor af-
ter the CCW surface in
the supply air duct is
short-circuited. ● Check the sensor's resistance complies with the actual tem-
perature. See temperature resistance table appendix 2.
● If the sensor resistance has significantly changed in value, it
should be replaced.
43 02 3 Temperature sensor af-
ter the CCW surface in
the supply air duct is
open-circuit. ● Check the sensor's resistance complies with the actual tem-
perature. See temperature resistance table appendix 2.
● If the sensor resistance has significantly changed in value, it
should be replaced.
43 03 3 The temperature sen-
sor in the supply to the
CCW surface in the ex-
tract air duct is short-
circuited. ● Check the sensor's resistance complies with the actual tem-
perature. See temperature resistance table appendix 2.
● If the sensor resistance has significantly changed in value, it
should be replaced.
43 04 3 The temperature sen-
sor in the supply to the
CCW surface in the ex-
tract air duct is open-
circuit. ● Check the sensor's resistance complies with the actual tem-
perature. See temperature resistance table appendix 2.
● If the sensor resistance has significantly changed in value, it
should be replaced.
43 05 3 Pressure gas tempera-
ture sensor has short-
circuited. ● Check the sensor's resistance complies with the actual tem-
perature. See temperature resistance table appendix 2.
● If the sensor resistance has significantly changed in value, it
should be replaced.
43 06 3 Pressure gas tempera-
ture sensor has been
interrupted. ● Check the sensor's resistance complies with the actual tem-
perature. See temperature resistance table appendix 2.
● If the sensor resistance has significantly changed in value, it
should be replaced.
43 07 3 Suction gas pressure
sensor has short-
circuited. ● Check connection between sensor and cooling control,
● Contact EXHAUSTO service.
43 08 3 Suction gas pressure
sensor has been inter-
rupted. ● Check connection between sensor and cooling control,
● Contact EXHAUSTO service.
43 09 3 Pressure gas pressure
sensor has short-
circuited. ● Check connection between sensor and cooling control,
● Contact EXHAUSTO service.
43 10 3 Pressure gas pressure
sensor has been inter-
rupted. ● Check connection between sensor and cooling control,
● Contact EXHAUSTO service.
43 11 3 Low pressure guard
has triggered a stop. Call a cooling technician.
43 12 3 High pressure guard
has triggered a stop. Call a cooling technician.
Three operational stops due to high pressure are permitted before
this alarm is triggered.
