APPENDIX 2 - FACTORY RUN TEST PROCEDURE
Each unit undergoes a final QA check before the unit
is shipped from the factory. This final check includes
a complete operational test that verifies the operation
of all of the systems and installed options on the unit.
This Run Test is built into and performed by the unit
controller (IPU). This mode can also be used in the
field to verify operation at start-up.
The unit will arrive in the field with all the ordered
options already configured. As part of start-up you
may need to change set points and turn features ON or
OFF based on the desires of the customer. Once con-
figured, the FACTORY RUN TEST mode can be used
to verify operation. The controller will begin with the
first applicable test in the order indicated in the table
below. The controller will prompt you with a question
“Initiate Test”. Indicate Yes by pressing the accept key
(check key) or move to a different test on the list by
pressing the up or down arrow keys. Pressing the can-
cel key will leave the RUN TEST mode.
For each test, the controller will indicate the test name
and the state of the test. For the state of the test, the
following information will be displayed:
• NO TEST – This message indicates that the test
shown has never been performed.
• UNDERWAY – This message indicates the test
shown has started.
• PASS – This message indicates the test shown
was completed successfully. When started in the
field all the items should show PASS.
• FAIL – this message indicates the test shown has
ended and was not successful.
