Voltage dip at Mark V during DC lube oil pump starting

We are facing resetting of Mark V when DC lube oil pump is started. I want to know up to what voltage Mark V system can sustain the voltage dip. Also, what can be the voltage dip when charger is working normally?

Your 125 VDC circuit has no ampere support or you DC motor is heavily grounded. I have seen this on the MK I turbine controller. Check for grounds on the DC lube oil pump motor. The DC lube oil pump also shares the same distribution panel (just above and to the right) as the 125 VDC distribution panel for the MK V and EX2000. Check for grounds. When the DC pump starts, the voltage drops below 90 VDC. Mk V resets.
