Sensor Fault
When a prealarm or cutout occurs, a flashing ALARM or
CUTOUT indicator will appear in the lower right hand cor-
ner of the Operating display. To determine the fault, rotate to
the Annunciator display by pressing the [CHANGE] key.
The Annunciator display lists all key operative points on four
sequential displays. These displays can be rotated from page
#1 through page #4 by pressing the [STEP] key. When a
prealarm or cutout is triggered, the pertinent point will flash,
and the time of the occurrence will be recorded to the right
of the alarm. Prealarms are self-clearing. At this time the
alarm will stop flashing, but the time of the first occurrence
will still be recorded to the right of the alarm. Pressing the
[CLEAR] key while at the Annunciator display will clear all
alarms and/or cutouts.
In order to restore the Annunciator display and resume nor-
mal operation it will be necessary to go through the follow-
ing steps:
1. Correct the conditions causing the alarm.
2. Press the [ALARM SILENCE] key. (This action may pre-
cede correcting the conditions causing the alarm).
3. To clear or reset the Annunciator pages, press the
[CLEAR] key. This will also clear the ALARM or CUTOUT
indicator from the Operating display.
4. Press [F1] to call up the Operating display. If the condi-
tions causing the alarm have not been corrected or a new
fault has occurred, a new ALARM or CUTOUT message will
appear.
NOTE: Use of the Emergency Stop Button may trip one
or more alarm setpoints.

The Shutdown Record display keeps a record of the last six
shutdowns (cutouts). This information will help troubleshoot
persistent operational problems. The most recent cutout will
appear on the top line of the display with the oldest appearing
on the last or bottom line. When a cutout occurs, all informa-
tion is moved down one line and the new cutout appears at
the top. When the display is full, the oldest record is dropped
off the display and is not retained in memory. The informa-
tion presented is echoed from the Annunciator display; pro-
viding the type of cutout, the day, the date, and the time.
NOTE: This information will not be lost due to power
failure.

The Freeze display has the same appearance and contains
the same information as the Operating display. (For a de-
scription of the information presented by the Freeze display,
refer to the Operating display.) The Freeze display freezes
the information of the Operating display AT THE MOMENT
OF A COMPRESSOR CUTOUT. The information on the
Freeze display can help the operator to identify the cause of
a fault which occurred when no one was present. The Freeze
display will retain the information generated by a cutout un-
til a new cutout occurs or power is removed from the micro-
processor.
Do not confuse the Freeze display
with the Operating display. In order
to avoid confusion remember that
the displayed information on the Operating display is
constantly being updated and changed. The Freeze dis-
play is fixed and FREEZE DISPLAY appears in the upper
left hand corner of the display.
NOTE: The Freeze display will appear as a blank screen
when power is initially furnished to the unit, and it will
return to a blank screen anytime power is removed from
the microprocessor.
