3.6) PRESSURE CONTROL DATA SHEET
DEFINITIONS:
“CONTROL” PRESSURE CONTROL This pressure control should be the only one controlling
the operating pressure of the generator.
“SAFETY” PRESSURE CONTROL This pressure control is only used if the “Control” fails. It
is always set higher than the “Control”; if the operating pressure is passed, The “Safety” will turn
the heaters off.
SAFETY RESET This reset is tripped when the “Safety” turns the heaters off. It must be
manually pushed to turn the heaters back on. This lets the user know there was a problem. If it is
tripped, the “Control” most likely failed.
PRESSURE ADJUSTING DIAL These dials adjust the set pressure at which each pressure
control will turn the heaters off.
DIFFERENTIAL ADJUSTING DIAL This dial is only on the “Control”. When the “Control”
turns the heaters off, the amount of pressure that is dropped before it turns the heaters back on (the
differential) can be adjusted by this dial. This dial should never have to be adjusted, unless desired.
PRESSURE GAUGE This tells the user what pressure is in the chamber. The pressure controls
are set to this gauge.
5 PSI PRESSURE CONTROL (Only used with “MAFD” Motorized Auto-Flush & Drain) this
control prevents the MAFD from opening when there is more than 5 pounds off pressure in the
generator.
