TROUBLESHOOTING
Fault diagnosis is As long as the mud level in the tank remains at or above the pump bolting flange,
the degasser will circulate fluid up to the spray tank. Malfunctions are generally caused by incoming
power disruptions or tripping of overloads or blown fuse(s) in the electrical power source. Always
check these items and for correct incoming power first before proceeding with further checking and
tests.
If degasser is equipped with a Derrick-supplied electrical control panel, an electrical schematic
diagram is included in Section 8 for assistance in tracing electrical malfunctions. If equipment is
operated by a customer-supplied starter box or other power source, consult the corresponding
electrical diagram for assistance in fault analysis. Before performing electrical continuity checks,
always shut down, lock out, and tag out electric power to degasser.
WARNING! TO AVOID SERIOUS PERSONAL INJURY BE SURE EQUIPMENT IS
LOCKED OUT, TAGGED OUT, AND DE-ENERGIZED PRIOR TO PERFORMING
MAINTENANCE.
