X9 

Change machine pressure-/flow characteristic curve. 

Open

 - the pressure is lower 

closed – higher pressure 

X20 

Cooling unit start  

*Open

 – waiting for start signal  

Closed – Continuous run 

X21 

Liquid temperature alarm.  

*Open

 – PTC monitoring by cooler  

Closed – PTC monitoring by power source 

X22 

Pump motor current minimum limit alarm, pressure low or no water. 

*Open

 – alarm on 

Closer – alarm off. 

 

H1 

Cooling liquid temperature too high. 

H2 

Pump motor current too low, no water. Alarm level can be adjusted 
by trimmer R57 (Default 230mV – 1,4A) 

H3 

Pump motor current too high. Blocked water hoses, no circulation. 

 
 
Adjusting pump motor current minimum: measuring points X7 and X8, adjust voltage using R57 to 230mV 
(current limit will be then 1,4A). When adjusting the current limit pump should not be running. 
 
Operational voltages and used connectors are the same as in the card SPW006214.
