EQUIPMENT PROTECTION
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 safety valve connection on the side
of the separator tank.
All sensors will automatically reset when the problem
condition is corrected.
Automatic Shutdown/Diagnostics
Should any of these problem situations occur, the unit
will automatically shutdown and stop.
BEFORE
restarting the unit or flipping the POWER switch to
“Off”, check the DIAGNOSTICS area on the
instrument panel.
In a shutdown situation, the function of the panel lamps
is to indicate what specific failure caused the unit to
shut down. These lamps will remain illuminated until
the Power Switch is turned “OFF”.
Note:
None of the panel lamps should be glowing
when machine is operating. If they are, shut unit down
and investigate.
The upper four (4) lamps are electronically “latched” to
only respond to the first or primary signal for a
shutdown. In other words, if the automatic shutdown
is the result of one of these four problems, only that
particular problem lamp will be lit. And the lamp will
remain lit as long as the batteries provide power.
Refer
to
OPERATING
CONTROLS
AND
INSTRUMENTS 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, evidence of excessive heat, etc.) and corrections
made.
Sensors (1) through (5) will automatically reset when
the problem condition is corrected.
Other possible causes for an unexpected shutdown
are listed on the Trouble Shooting Chart.
