NOTICE
Do NOT wire around or bypass a shutdown
sensor or switch.
All units in this family of machines are protected by five
(5) sensors or switches at the following locations:
(1) High engine COOLANT temperature in the engine.
(2) Low engine oil pressure, in the engine.
(3) Low Fuel Level. (First, the light on the control panel
will come on as a warning).
High Discharge AIR Temperature
(4) At the airend outlet.
(5) In the side cover of the separator tank.
All sensors and additional low oil pressure switch
(mentioned above) will automatically reset when the
problem condition is corrected.
UNITS RATED BELOW 200 PSI (1400 kPa)
These units include an additional low oil pressure
switch in the supply line to the airend bearings.
AUTOMATIC SHUTDOWN / DIAGNOSTICS
Should any of these problem situations occur, the unit
will automatically shutdown and stop. BEFORE re-
starting the unit or flipping the POWER switch to “Off”,
check the DIAGNOSTICS area on the instrument pan-
el.
The upper four (4) lamps are electronically “latched” to
only respond to the first or primary signal for a shut-
down. In other words, if the automatic shutdown is the
result of one of these four problems, only that particu-
lar problem lamp will be lit. And the lamp will remain
lit as long as the batteries provide power.
Refer to OPERATING CONTROLS AND INSTRU-
MENTS, for the various problem signal criteria (
°
F, psi,
etc.). The indicated problem area should be inspected
for a physical cause (low fluid, broken fan belt, evi-
dence of excessive heat, etc.) and corrections made.
