The Diagnostic Test Plug should only be used by a technical representative from
Parker in order to diagnose compressor issues. Please keep this plug with the
generator’s documentation or accessories.
!
!
!
Description
: The purpose of this test is to isolate and verify that the generator’s compressor reaches
max pressure (specified in the Table in Step 5)
within 2 minutes. If the Pressure is OK then the
pressure problem is downstream of the compressor.
!
Diagnostic Procedure
!
1. Power Down generator and allow enough time for the generator to depressurize, verify by
observing the generator’s pressure gauge located on the front panel.
!
Note: It can take up to an hour if fully pressurized.
!
!
2. On the back panel, locate the air outlet connection (not labeled) that
connects to black separator assembly.
!
!
3. While pushing down on the connection’s collar, pull to remove the
3/8” tubing from this location.
!
!
!
!
!
4. Insert The Diagnostic Plug into this connection.

5. Power ON generator, and time how long the generator takes to come up to max pressure and
shuts off the pressure switch. Refer to chart below for times. If test passes, then the problem is
downstream of the compressor. If test fails a problem resides with compressor.
