ice the air filter.
• The sump tank separator element restric-
tion gauge is provided to monitor sump
tank separator element restriction. A reading
over 10 psid (0.7 bar) or in red zone, indi-
cates time to service the element.
• The scroll switch toggled to the left will indi-
cate gauges pertaining to the engine.
Toggled to the right will convert reading from
Metric to English.
• Check engine and warning lamp for further
engine diagnostics. See Section 2.9 and
Table 2, Possible Performance Effect of
Active Diagnostic Codes.
• The compressor discharge high tempera-
ture light or the low fuel level light will
remain on, indicating the specific problem,
until the rotary switch (engine switch) is
turned to "OFF" position. When the starter
switch is initially turned on, the lights will
come on to check bulb function. The lights
should go out after 15 seconds.
• The low fuel lamp indicates a low fuel shut-
down or open circuit.
• The compressor high temperature lamp
indicates a receiver or discharge high tem-
perature shutdown. Could also indicate an
open circuit.
• HI/LO selector valve; HI position allows
machine to operate at rated pressure (350
psig [24.1 bar]). The LO position forces
machine to run at ( 175 psig [ 12.1 bar])
rated speed.
2.9 ENGINE CONTROL MODULE, FUNCTIONAL
DESCRIPTION
Diagnostic Fault Codes are provided to indicate an
electrical or electronic problem has been detected
by the ECM (Engine Control Module). In some
cases the engine performance can be affected
when the condition causing the code exists. More
frequently, however, the operator cannot detect any
difference in the engine performance.
If the operator indicates a performance problem
occurs whenever the Check Engine Lamp is flash-
ing, the diagnostic code may indicate the cause of
the problem, and should be corrected.
If the operator does not indicate a problem with the
engine performance and a diagnostic code is
logged by the ECM, it indicates the ECM detected
an abnormal condition, but it did not affect perform-
ance.
If this is the case, unless there are several occur-
rences of the code in a very short period of time, or,
the ECM is indicating an Active Code at the present
time, there is most likely nothing wrong with the sys-
tem.
The diagnostic FLASH CODE may be retrieved
using this lamp.
The lamp is not required for engine operation, how-
ever it can be useful to determine Active diagnostic
codes. The lamp will illuminate (ON) at initial ECM
