Alarms Menu
The Alarm List menu displays alarm codes.
Alarm codes are recorded in the controller
memory to simplify unit diagnosis procedures.
Some alarm codes are only recorded during a
pretrip (PTI) test or function test. Fault codes are
retained by the controller in a non-volatile
memory. If the Alarm LED is on or flashing on
and off, enter the alarm list to view the alarm.
A complete listing of the controller operating
menu is located on an 11” x 17” fold out on the
last page of this manual.
Alarm Types
There are two types of alarms:
Shutdown Alarm (Level 1):
Alarm LED flashes
and unit stops. Shutdown alarms indicate the unit
has been stopped to prevent damage to the unit or
cargo. The condition must be corrected before
restarting the unit. Alarm code 56 (compressor
temperature too high) is a shutdown alarm.
Check Alarm (Level 2):
Alarm LED flashes until
alarm is acknowledged. Check alarms indicate
corrective action should be taken before a
problem becomes severe.
Alarm Code States
There are three alarm code states for Shutdown
and Check alarms:
Not Active:
An alarm condition has occurred but
no longer exists in the unit. Not Active means the
condition was corrected and did not recur for 1
hour; or the Unit On/Off switch was turned Off
and then On.
When a Not Active alarm code is acknowledged
(
F4
key pressed while alarm code appears in LCD
display): The Alarm LED will turn off and the
alarm code disappears from the alarm list.
Active:
An alarm condition has occurred and
continues to exist in the unit; or the alarm
condition occurred within the past 1 hour but does
not currently exist in the unit.
If the alarm condition no longer exists in the unit
and the alarm code is acknowledged: The Alarm
LED will turn off and the alarm code disappears
from the alarm list.
