Alarm text Description
High air temp. (A,B,C,D) The air temperature has been above the high alarm limit for longer time than set delay
Low air temp. (A,B,C,D) The air temperature has been below the low alarm limit for longer time than set delay
Frost protection, too low S4 The air off temperature (S4) is below the set frost protection limit
(A,B,C,D)
High Prod. temp. (A,B,C,D) The product temperature has been above the high alarm limit for longer time than set delay
Low prod. temp. (A,B,C,D) The product temperature has been below the low alarm limit for longer time than set delay
Po sensor error Pressure transmitter signal for evaporating pressure faulty
S2A sensor error (B,C,D) S2A temp. sensor signal faulty
S3A sensor error (B,C,D) S3A temp. sensor signal faulty
S4A sensor error (B,C,D) S4A temp. sensor signal faulty
S5-1A sensor error (B,C,D) S5-1A temp. sensor signal faulty
S5-2A sensor error (B,C,D) S5-2A temp. sensor signal faulty
Product temp. A sensor error Product temp. sensor signal faulty
(B,C,D)
Pc sensor error Pressure transmitter signal for condensing pressure faulty
Control stopped, The control has been stopped via the setting "Main switch" = ON or via the external Main switch
MainSwitch=OFF input
Refrigerant changed The refrigerant setting has been changed
Case cleaning initiated A case cleaning has been initiated
Door open pre alarm The door has been open for longer time than 75% of the set alarm delay
Door open alarm The door has been open for longer time than set alarm delay
Injection problem (A,B,C,D) The AKV valve can not control the superheat of the evaporator
Max defrost time exceeded The last defrost cycle has terminated on time instead of temperature
(A,B,C,D)
Max fan del ay time exceeded The fans have been started on time instead of temperature after a defrost
(A,B,C,D)
Max defrost hold time After a defrost cycle the evaporator has restarted cooling as it did not get a release signal via the
(A,B,C,D) defrost co-ordination setup in the network manager (AKA gateway)
AD - Case X - Air flow reduced The air flow at the evaporator is greatly reduced – either as a consequence of severe ice formation, a
fan fault or other obstruction.
AD - Case X not defrosted The air flow is continuously reduced after defrost has been carried out
AD - Sensor error A,B,C,D Tuning problem in adaptive defrost
AD – Flash gas detect A,B,C,D Flash gas has been detected at the valve for a relatively long time
