NOTE ON TRANSDUCERS:
Whenever a sensor is suspected of fault, the recom-
mended cause of action is to measure the signal
(pressure, temperature, etc.) with an alternate cali-
brated instrument and compare readings. If read-
ings conflict, the electrical and/or tubing connec-
tions should be inspected, and if no faults are evi-
dent, then replace the sensor and re-evaluate
against the calibrated instrument.

9.3 CALIBRATION

The Supervisor II has software calibration of the
pressure and temperature probes. This calibration
affects the offset but not the slope of the pressure
and temperature calculations. Because of this, the
most accurate method is to heat or pressurize the
transducer to its operating value. If this is too diffi-
cult, room temperature/open atmosphere calibra-
tion is adequate. Calibration may only be done while
machine is stopped and unarmed.
To enter calibration mode, you must press the fol-
lowing keys in sequence while in the default status

PROBABLE CAUSE
Air Demand Exceeds Supply
Inlet Air Filter Clogged
Inlet Valve Not Fully Open
Pressure Sensor and/or Connections
at Fault
Pressure Sensor P2 at Fault
Unloading Device (i.e., Blowdown
Valve, Sullicon Actuator, Optional
Spiral Valve) Failed to Operate
Solenoid Valve Failed
to Operate
Control Air Signal Leaks
Control Air Signal Filter Clogged
Clogged Return Line Strainer or
Orifice
Damaged or Improperly Gasketed
Separator Elements
Fluid System Leaks
Fluid Level Too High
Excessive Fluid Foaming
Check air service lines for open
valves or leaks.
Check for maintenance message
on Supervisor display. Inspect and/or
change element.
Check actuation and butterfly disc
position.
Check connections from trans-
ducer. If adequate, replace trans-
ducer.
Check connections from trans-
ducer. If adequate, replace
transducer.
Check operation of unloading device.
Check operation of solenoid
valve.
Check tubework feeding control
signal for leaks.
Service filter assembly.
Clean strainer - screen and o-ring
replacement kit available. Clean
orifice.
Inspect separator elements and
gaskets. Replace if damaged.
Check tube/pipework for leaks.
Drain excess fluid.
Drain and change fluid.

In the above example, "0" refers to the amount of ad-
justment (in psi or °F, "97" refers to the current value
of P1).
To make adjustments, Press the "
ROW) key to increase the value, press the "
(DOWN ARROW / LAMP TEST) key to decrease
the value. The number on the left will increase or de-
crease always showing the total amount of adjust-
ment. Maximum adjustment is + 7.
The DSP key exits, wiping out changes to the cur-
rent item, while saving changes to any previous
items. The PRG key saves the current item and ad-
vances to the next. All temperatures and pressures
may be calibrated individually.
