FACTORY RUN TEST FEATURE
All operational tests are performed at the factory and
must pass before the unit is shipped. For startup pur-
poses, use the Supply Fan, Water Flow Switch, All
Compressors, and Damper Tests. The High Potential
test is completed at the factory. The Stage Electric
Heat (if installed) test is completed later. The Water
Flow Switch, Damper, and Electric Heat are options
and may not show on the test list.
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 arrives in the field with all the ordered op-
tions 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 configured,
use the FACTORY RUN TEST mode to verify opera-
tion. The controller begins with the first applicable test
in the order indicated in the table below. The control-
ler prompts you with a question “Initiate Test”. Press
the accept key (check key) to confirm or move to a
different test on the list by pressing the up or down ar-
row keys. Press the cancel key to leave the RUN TEST
mode
For each test, the controller indicates the test name and
the state of the test. For the state of the test, the follow-
ing information is displayed:
• NO TEST – indicates that the test shown has nev-
er been performed.
• UNDERWAY – indicates the test shown has start-
ed.
• PASS – indicates the test shown was completed
successfully. When started in the eld all the
items should show PASS.
• FAIL – indicates the test shown has ended and
was not successful.
To start the test, turn the UNIT rocker switch to the
OFF position. Press the SERVICE key and enter pass-
word 9725. See Section 6 of the IOM for information
on how to enter the PASSWORD.
Use the down arrow key to scroll down to FAC-
TORY RUN TEST. Press the check key (√) and use the
right arrow key to change from USER DISABLED
to USER ENABLED. Press the check key (√ ). The
following test sequences appear:
SUPPLY FAN TEST FOR CONSTANT VOLUME
OR VAV/FLEXSYS UNITS
During this test sequence, the supply
fan blower operate at 42 Hz. Make sure
this speed not result in a static pressure
which could damage the building supply
duct system.
To initiate the test press the check key (√ ). The control
asks you ARE YOU SURE? Press the check key (√ )
again.
Once underway, the controller performs the following
sequence:
1. Start the Supply Fan and set the Supply Fan VFD
output to 50%.
2. Wait 30 Seconds.
3. Stop the Supply Fan.
After the fan starts to verify that the LED light at BI1
has lit or locate the Supply Fan Status in the DI sec-
