SURVEY OF ALARM AND CUTOUT TEXTS

 

 
In case of an alarm or a cutout the text "ALARM" or "CUTOUT" will appear in the top left-hand corner of the 
display followed by the alarm cause. Here you find a survey of alarm and cutout messages. 
 
CUTOUT FILTERDIF. 
 

Pressure drop over oil filter too high (set point K/F4). 

 

This cutout has a delay of 5 minutes. 

 
CUTOUT HT-OIL 
 

Maximum oil temperature (set point J/F2), measured in the oil manifold, has been exceeded. 

 

This cutout has a delay of 3 minutes. 

 
CUTOUT I-DATA 
 

Transformer factor under set point I/F5 not entered. 

 
CUTOUT LT-OIL 
 

Below minimum temperature in oil separator (set point J/F4). 

 
CUTOUT MOTOR 
 

No feedback from the compressor motor that it is running. 

 
CUTOUT LEVEL 
 

Oil level in oil separator too low. 

 
CUTOUT P-DISCH. 
 

Maximum permissible discharge pressure (set point C/F2) exceeded. 

 
CUTOUT OIL DIFF. 
 

The necessary oil differential pressure entered under set point K/F2 not available. Delay: 3 minutes. 

 

This cutout text will also appear, if the oil differential pressure si < 0 (zero), delay 45 sec during start 
up. 

 
CUTOUT R-DATA 
 

Refrigerant (set point R/F5) or compressor type (set point R/F2) not entered. 

 
CUTOUT T-DISCH. 
 

Maximum permissible discharge pipe temperature (set point L/F4) exceeded. 

 
CUTOUT EXTERN 
 

  IN 7 is OFF, which means that the emergency stop, the safety pressure control KP7ABS or another 

external fault has stopped the compressor. 

 
CUTOUT VALVE 
 

At starting up of compressor the oil pump is started to press the capacity slide to minimum. If the slide 
is not in its minimum after 5 minutes the oil pump is stopped, and the text "CUTOUT VALVE" 
appears in the display.
