The Checkout tests can all be performed at the time of installa-
tion or at any time during the operation of the system as a test that
the system is operable.
TROUBLESHOOTING
Alarms — The economizer module provides alarm messages that
display on the 2-line LCD.
NOTE: Upon power up, the module waits 60 minutes before
checking for alarms. This allows time for all the configured
devices (e.g. sensors, actuator) to become operational. The excep-
tion is the SAT sensor which will alarm immediately.
If one or more alarms are present and there has been no keypad
activity for at least 5 minutes, the Alarms menu displays and cy-
cles through the active alarms.
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
(Menu up/Exit) button to complete the action
and return to the previous menu.
NOTE: If the alarm still exists after you clear it, it is redisplayed
within 5 seconds.
WARNING
Failure to follow this warning could result in personal
injury, property damage, or death.
Before performing service or maintenance operations on
unit, always turn off main power switch to unit and install
lock(s) and lockout tag(s). Unit may have more than one
power switch. Ensure electrical service to rooftop unit
agrees with voltage an amperage listed on the unit rating
plate.
If any wiring changes are required, first be sure to re-
move power from the Economizer module before starting
work. Pay particular attention to verifying the power con-
nection (24 Vac).
CAUTION
Failure to follow this caution may result in damage to
equipment. Be sure to allow enough time for compressor
startup and shutdown between checkout tests so that you
do not short-cycle the compressors.
