Should trouble persist, check whether
motor starter contacts are functioning
properly.

Inlet Air Valve Not Fully Open
Check actuation and butterfly disc
position.
Low oil pressure defective control
solenoid valve.
Transducer P2 Malfunction
Check connections from trans---
ducer. If adequate, replace trans---
ducer.
Blowdown Valve Leaking
Refer to Component Manual for
or Sluggish

Limit Switch Controlling BVD Failed
Check limit switch and cam adjuster
to Operate
on butterfly valve.
Defective LP Stage
Consult Sullair Service Department.

valve maintenance.
Inlet Throttling Valve Not Fully Open
See inlet valve adjustment.
Limit Switch Controlling BVD Failed
Check limit switch and cam adjuster
to Operate
on butterfly valve.
Transducer P2 Malfunction
Check connections from transducer.
If adequate, replace transducer.
Control Air Filter Clogged
Refer to Component Manual for valve
maintenance. Check operation of limit
switch.
NOTE ON TRANSDUCERS:
Whenever a sen-
sor is suspected of fault, the recommended
cause of action is to measure the signal (pres-
sure, temperature, etc.) with an alternate cali-
brated instrument and compare readings. If
readings conflict, the electrical and/or tubing
connections should be inspected, and if no
faults are evident, then replace the sensor and
re---evaluate against the calibrated instrument.
8.3 CALIBRATION
The Supervisor
II
has software calibration of the
pressure and temperature probes. This calibra-
tion affects the offset but not the slope of the
pressure and temperature calculations. Be-
cause of this, the most accurate method is to
heat or pressurize the transducer to its operating
value. If this is too difficult, room temperature/
open atmosphere calibration is adequate. Cal-
ibration may only be done while machine is
stopped and unarmed.
NOTE
Calibration mode may be entered from the de-
fault display mode when the machine is in
“MANUAL” SHUTDOWN.
To enter calibration mode, you must press the
following keys in sequence:
“LOGO”, DELTA,
DSP, “ ”, PRG
. Once in calibration mode, you
will see a screen like the following: In the above
example, “0” refers to the amount of adjustment
(in psi or
_
F, “97” refers to the current value of
P1).
CAL P1
97
0
To make adjustments, Press the
“DELTA”
key to
increase the value, press the
“ ”
key to de-
crease the value. The number on the left will in-
crease or decrease always showing the total
amount of adjustment. Maximum adjustments is
+/---7.
Other keys operate the same as in program
mode. The
“LOGO”
key restores the original val-
ue of the current item. The
“DSP”
key exits, wip-
ing out changes to the current item, while saving
changes to any previous items. The
“PRG”
key
saves the current item and advances to the next.
Items following P1 calibration are (in order): P1,
P2, P3, P4, T1, T2, T3, T4 and T5 calibration.
