"EoF"

Min. 0 Hz
Max. 200 Hz
Default 100 Hz

Frequency during Sensor error
Frequency at which compressor must run during cab air sensor error. In case of cab air sensor error controller will send this 
frequency to compressor drive during Error run time "Ert". and during error stop time it will send the Off frequency "CoF"

"Ert" 

Min. 0 min 
Max. 60 min 
Default 5 min  

Error Run Time 
This parameter only become active in the unlikely event of cabinet air sensor error. Ert define the duration the refrigeration 
system will run during cab air sensor error. 
Example: "Ert=4" [min] and "ESt=16" [min] will provide an average cooling system activity of 20%. Ert and "ESt" values must be 
configured based on OEM experience   

"ESt" 

Min. 0 min 
Max. 60 min 
Default 5 min

 Error Stop Time 
This parameter only become active in the unlikely event of cabinet air sensor error. ESt define the duration the refrigeration 
system will stop during cab air sensor error

"CSt"

Min. 0 min
Max. 30 min
Default 2 min

Minimum Stop Time
It determines the minimum number of minutes the compressor must remain idle before a Temperature cut-in can take effect. For 
example, if the temperature sensor indicates that the cut-in temperature has been reached, but the number of minutes set in this 
parameter have not elapsed since the compressor last stopped, then the compressor will stay OFF.
It will only start once the duration given by "

CSt

" has been reached provided the temperature is still high enough. "

CSt

" thus 

overrides the cut-in.

"Crt"

Min. 0 min
Max. 30 min
Default 0 min

Minimum Run Time
It determines the minimum number of minutes the compressor must run before a Temperature cut-out can take effect. For 
example, if the temperature sensor indicated that the cut-out temperature has been reached, but the number of minutes set in 
this parameter have not elapsed since the compressor last started, then the compressor will continue. It will only stop once the 
duration given by "

Crt

" has been reached – provided the temperature is still low enough.

"

Crt

" thus overrides the cut-out.

"uSt"

Min. 0 sec
Max. 30 sec
Default 1 sec

Minimum On time at Start Speed 
Minimum time the compressor must run at start speed

"Cdd"

Min. 0 min
Max. 15 min
Default 15 min

Compressor Door Open Delay/Cdd 
This parameter sets the delay in minutes before the compressor stop frequency signal 
when the door is opened. If set to 15, the function is disabled.

"Srt"

Min. 0 min
Max. 60 min
Default 0 min

System resume after door open
Fan and Compressor resume after cut out by door open.

Con

Condenser Protection settings

NOTE: A condensor temperature sensor is required to use these parameters.
Condenser protection is generally used in dusty environments where 
the condenser may accumulate a layer of dust or dirt and therefore be 
at risk of overheating.

"CAL"

Min. 0°C
Max. 200°C
Default 80°C

Condenser Alarm Limit/CAL
This parameter sets the temperature for the condenser at which an alarm 
will be generated.

"CbL"

Min. 0°C
Max. 200°C
Default 85°C

Condenser Block Limit/CbL
This parameter sets the temperature which if reached will cause the 
compressor to switch OFF.

"CoL"

Min. 0°C
Max. 200°C
Default 60°C

Condenser OK Limit/CoL
This parameter sets the temperature at which the compressor is 
allowed to start again after the temperature set in "

CbL

" above has been 

exceeded and the compressor stopped.
