TROUBLESHOOTING

Alarms
The Economizer module provides alarm messages that
display on the 2-line LCD.
NOTE: JADE will be in the "set up" mode for the first 60
minutes after powered. If a sensor for OA air or
Sylkbus device (sensor, actuator) is discon-
nected during the set up mode, the JADE will not
alarm that failure. The MA sensor is a system
"critical" sensor; if the MA sensor is removed
during the set up mode, the JADE will alarm.
After 60 minutes the JADE controller will change
to operation mode and all components removed
or failed will alarm in the operation mode.
You can also navigate to the Alarms menu at any time.
Clearing Alarms
Once the alarm has been identified and the cause has been
removed (e.g. replaced faulty sensor), the alarm can be
cleared from the display.
To clear an alarm, perform the following:
1. Navigate to the desired alarm.
2. Press the  button.
3. ERASE? displays.
4. Press the  button.
5. ALARM ERASED displays.
6. Press the
button (MenuUp/Exit) to complete the
action and return to the previous menu.
NOTE: If an alarm still exists after you clear it, it re-dis-
plays within 5 seconds.

Checkout Tests

Use the Checkout menu (Table 4) to test the damper operation
and any configured outputs. Only items that are configured
are shown in the Checkout menu.
NOTE: See "Interface Overview" on page 18 of 63-2700 for
information about menu navigation and use of the
keypad.
To perform a Checkout test:
1. Scroll to the desired test in the Checkout menu using
the
and
buttons.
2. Press the  button to select the item.
3. RUN? appears on the display.
4. Press the  button to start the test.
5. The unit pauses and then displays IN PROGRESS.
6. When all parameters have been tested, press the
button (Menu up) to end the test (e.g. turn off the relay).
The checkout tests can all be performed at the time of
installation or any time during the operation of the system as a
test that the system is operable.
CAUTION
Equipment damage may result.
Be sure to allow enough time for compressor startup
and shutdown between checkout tests so that you do
not short-cycle the compressors
