APPENDIX 2 - FACTORY RUN TEST PROCEDURE
Prompt Message #2
ROTATION CORRECT? – As the supply fan coasts
down, you can open the door and verify proper rota-
tion. Press the check key if the rotation is correct. If
not, identify why the rotation is wrong, and correct.
If both messages are accepted, PASS will be indicated
at the display. Use the down arrow key to move to the
next test.
COMPRESSOR SYSTEM TEST
(A, B, on all units; C and D on units 39 tons and great-
er; E and F on units 100 tons and greater).
To initiate the test press the check key (√ ). The control
will ask you ARE YOU SURE? Press the check key
(√ ) again.
Once underway, the controller will perform the fol-
lowing sequence:
1. Set COMPRESSOR A to ON.
2. Wait 5 Seconds.
3. Turn COMPRESSOR A to OFF.
Prompt Message #1
ROTATION CORRECT FOR 1A? – To verify proper
rotation you need to attach a gauge set to the com-
pressor system prior to conducting the test. If rota-
tion is correct, the discharge pressure should increase
rapidly. If the discharge and suction pressures remain
the same, the rotation is not correct. Press the check
key (√ ) if the compressor rotation is correct.
During this test sequence, the supply fan
blower will operate at 50 hertz. Make sure
this speed will not result in a static pres-
sure which could damage the building
supply duct system.
Perform the following:
1. Set the SUPPLY FAN to ON.
2. Set SUPPLY FAN VFD AO to 60%.
3. Wait 30 Seconds.
4. Set COMPRESSOR A to ON.
5. Wait 180 seconds.
6. Set COMPRESSOR A to OFF.
26
7. Wait 10 seconds.
8. PASS will be indicated for this test and all outputs
will be turned OFF.
If at any time during this test, the Com-
pressor System #1 status is not OKAY, all
outputs will be immediately turned OFF
and FAIL will be indicated for the test.
Repeat the above procedure for each of the compressor
systems.
ANALOG OUTPUT OPERATION TEST
To initiate the test press the check key (√ ). The control
will ask you ARE YOU SURE? Press the check key
(√ ) again.
Once underway, the Unit Controller will perform the
following sequence:
1. Set OUTSIDE AIR / RETURN DAMPER to
50%.
2. Set the CONDENSER WATER VALVE to 50%.
3. Set the CONDENSER BYPASS VALVE (if pres-
ent) to 50%.
4. Set the HOT WATER / STEAM VALVE (if pres-
ent) to 50%.
5. Wait 45 seconds.
Prompt Message #1
ALL DAMPERS OPEN 50%? – Check the above ac-
tuators and verify they are approximately 50%. If they
are press the ACCEPT - check key (√ ).
If the actuators operated properly, use the down arrow
key to move to the next test.
STAGED ELECTRIC HEAT TEST
This test can be run in one of two ways. The electri-
cal circuit could be checked without turning on the
heaters by removing the fuses feeding the electric heat
elements. Or if the fuses are left in place, the heater
elements will be energized. If the heater elements are
energized, the supply fan must be turned on or there is
a possibility the limits will trip. The following proce-
dure will turn on the supply fan:
