What to do if KKT Chiller pump 1 motor protection has triggered?
If the pump 1 motor protection has triggered, it could be due to the motor current being outside the permitted range or the pump being blocked. Check pump 1 for a short-circuit in the supply cable, an internal short-circuit in the motor windings, or if the motor is blocked. Also, verify if the load contactor is working correctly.
What to do if the KKT Chiller pump 1 flow is insufficient?
If pump 1 flow is insufficient, it may be due to high pressure loss. Check the external piping for closed gate valves, a blocked water filter, or system leaks.
