FIGURE 41 - FAILURE AND ALARM SCREEN

This screen displays failure indications (time-outs, op-
eration interlock, overcooled refrigerant, over and un-
der temperatures, and problems with the unit's pumps)
and system alarms.
The failure light in the upper right corner is red. The
alarm light is orange.

Failure

When a failure occurs, an alarm sounds (buzzer). The
type of failure button lights in the Failure section of
the screen. Press the BUZZER STOP button to turn
off the alarm sound. This can be done even before the
failure is addressed. Turning off the buzzer does NOT
fix the problem.
Press the lit failure button to access an on-screen han-
dling guide for each item. An on-screen guide is avail-
able for each item in the Failure and the Alarm sec-
tions. See an example to the right.
