Over Pressure Problem Correction - Glas Craft MH II User Manual

In an over pressure situation, the system will remain
shut down until it is manually reset.
At this point, it is necessary to determine if the problem
is an over pressure situation.
When the sensor engages, the system will be frozen,
giving you the pressure readings at the time the problem
was detected.
Inspect the fluid pressure gauges, in an over pressure
situation, one of the fluid pressure gauges will be
significantly higher than the other gauge.
