Fault messages / error codes at (blue) IMP pumps
Fault messages / error codes at (blue) IMP pumps
Answer
Typical reasons for fault messages of the pumps in operation:
1.air inside the liquid cooling system (try to bleed the system by opening the related valves / make sure that there is a bleeding valve installed at the highest point of the cooling system)
2. deposits inside pump make it getting blocked or running tight (flush the pump by manually running at 100% speed for 5 minutes; if situation will not improve, replace the pump)
3. check and clean the filter inside the coolant system
4. run the system with latest software version (SW 20.0.2 has an improved regulation algorithm for the pumps and SW 21.0. has an additional flushing cycle for pumps, giving sporadic errors)
