Question
recently we have an issue where a zr400 compressor starts but cannot load due to low inter cooler pressure

Hi,
It is a safety to protect the machine. Please let me know the intercooler pressure when the machine runs unloaded.
I believe most machines will trip around -0.7 bar (vaccuum).
How old is the machine? If you are getting close to 40.000 running hours, it's probably the LP element that needs overhauling.
Best,
Cas
