COMPRESSOR MOUNTING
Portable compressors, which are modified to remove the running gear
and mount the compressor directly to trailers, truck beds or frames, etc.
may experience failure of the enclosure, frame, and/or other
components.
It is necessary to isolate the compressor package from the carrier
basewith a flexiblemounting system. Such a system must also prevent
detachment of the package from the carrier base in the event the
isolators fail.
Contact your Portable Power representative for flexible mounting kits.
Warranty does not cover failures attributable to mounting of the
compressor package to the carrier base unless it is a Portable Power
provided system.

FAULT DETECTION
Flash out of fault codes: Fault flash out mode can be entered through
the use of a diagnostic switch located next to the fault lights. To enter
the flash fault out mode, the keyswitch must be ON, with the engine not
running. When a diagnostic switch is used to enter the mode, the ECM
will automatically flash the first fault code after the code is turned on.
The diagram below depicts the pattern of the fault code flash out
scheme as indicated by the stop lamp. A blink is equavalent to the stop
lamp being ON for 0.5 seconds and OFF for 0.5 seconds. A pause
between fault code digits has duration of 2 seconds.
Example: Diagnostic lamp diagrams
Fault Code 244
Fault Code 112
Fault lamps: If the keyswitch is turned ON, but the diagnostic switch
remains OFF, the indicator lamps will illuminate for approximately 2
seconds and then go off, one after the other, to verify they are working
and wired correctly.
In the illustration below, the indicator lamps are all on and then go off
one at at time, at an interval of 0.5 seconds each.
Fault lamp sequence
• Warning Lamp - The warning lamp provides important operator
messages. These messages require timely operator attention. The
warning lamp is also used to delineate diagnostic fault codes.
• Stop Lamp - The stop lamp provides critical operator messages.
These messages require immediate and decisive operator response.
The stop lamp is also used to flash out diagnostic fault codes.
NOTE: The maintenance schedule in this manual describes the
service intervals that should be followed for normalapplications of this
compressor. This page may be reproduced and used as a checklist
by service personnel.
In more severe applications such as sandblasting, quarry drilling, well
drilling, and oil and gas drilling, more frequent service intervals will be
required to ensure long component life.
Dust and dirt, high humidity, and high temperatures will affect
lubricant life and service intervals for components such as inlet air
filters, oil separation elements and oil filters.
