P-T Unit Self Check Test
The Unit Self Check is a functional test of the
unit’s operating capability. Once the test is started
by the operator, it is fully automatic and requires
no operator attendance.
Starting the Unit Self Check
The following steps are necessary to start a Unit
Self Check:
1. Turn the On/Off switch On.
2. Clear any alarms.
3. Press and hold the
TK L
OGO
key for at least
3 seconds until the Unit Self Check [USC]
prompt screen appears.
4. Press the
E

show [Lod] and the unit will then start the
Unit Self Check.
If any alarms were not cleared before starting the
Unit Self Check, they will be displayed at this
time. They can be cleared by pressing the
E
NTER
key.
The balance of the Unit Self Check is fully
automatic and requires no operator attendance.
The following tests are performed:

the diesel engine.

All segments of the display will be lighted at the
same time.
Show Programmable Settings
All programmable settings will be sequentially
displayed. These settings may be verified by the
operator if necessary.

RPM Check
The diesel engine RPM is checked in both high
and low speed.
Cooling Check
The ability of the unit to cool is checked.

Unit Self Check Report
At the completion of the Unit Self Check, the
check results will appear on the display. They will
remain until any key on the controller is pressed.
Check results are shown as either [PASS],
[CHEC] or [FAIL].
[PASS]—The unit has passed the Unit Self Check.
[CHEC]—Stored or check alarm conditions were
detected during the Unit Self Check. These alarms
will be preceded by a dash (-) to indicate that they
were detected during a Unit Self Check.
[FAIL]—Shutdown alarm conditions were
detected during the Unit Self Check and the unit
has been shut down to prevent possible damage.
This will occur as soon as a shutdown condition is
detected. The Unit Self Check will not be
completed.
If check or shutdown alarms are detected during a
Unit Self Check the condition(s) should be
corrected and the check repeated before releasing
the unit for service. See the

P-T Microprocessor
Diagnosis Manual for details.
