5.2.2 Component Test Mode
WARNING
If the unit is in Standby Operation and
powered, voltage will be applied to high
voltage components (i.e. the fan motor con-
tactor) and those components will operate
(i.e. the fan blades will turn) when those
components are energized using Compon-
ent Test Mode.
Component Test Mode allows the technician to energize
individual circuits for 5 minutes at a time. The engine or
compressor, when in Standby Operation, is not allowed
to start when the microprocessor is in Component Test
Mode. To enter the Component Test Mode:
a. Enter the Technician Interface - Component Test
Mode as described in Section 5.2.
b. To read through the Component Test list, press either
the UP or DOWN ARROW keys. The list is circular,
meaning that once the end is reached, it is repeated
from the beginning. Refer to Table 5
−
1 for a list of
component tests available.
c. Once the desired test is displayed in the Mes-
sageCenter, press the ”=” key to select that test. For
example, if Buzzer is selected, the buzzer will come
on, and “BUZZER OFF IN 5 MINUTES” will display in
the MessageCenter. The minutes will count down to 0
at which time the buzzer circuit will be de-energized,
and the MessageCenter will display the last compo-
nent tested.
Should you need more than 5 minutes, the timer may
be reset for another 5 minutes anytime during the test
by pressing the “=” key. The timer may only be reset
once during each test. After the 5 minute timer ex-
pires, the MessageCenter will return to the Compo-
nent Test Mode Menu, and display the last compo-
nent tested.
To retest the same component and circuit again,
press the “=” key. Press the UP or DOWN Arrow key
to select another component.
To stop an individual component test, press and hold the
“=” key for 6 seconds. The microprocessor will still be in
Component Test Mode, and ready for another
component to be selected. To stop component testing,
and turn the microprocessor off, place the Main Power
switch in the OFF position.
To go to Configuration Mode or Service Mode, select
Main Menu and press the “=” key.
The only keys that operate during Component Test
Mode are the ALARM and SELECT keys. The alarm list
is available for review of any active or inactive alarms.
The SELECT key will only allow access to the data list
Amp Draw information for the component that is
currently being tested.
