ALARMS/SHUTDOWNS MESSAGES
Auxiliary Digital Input #0-4 Shutdown (Zone 1 – 30) - A unit
Shutdown has occurred and message issued because the input
value to the Auxiliary Digital 0-4 input channel has not been
detected, and the Delay for that setpoint has timed out. This
setpoint is located by accessing MENU > SETPOINTS > AUXIL-
IARIES > DIGITAL INPUTS.
Consecutive Defrost Warning (Zone 1 – 30) – If the Max Con-
secutive Defrost value is exceeded, this Warning will occur.
Control Temperature 1 Sensor Fault (Zone 1 – 30) - This
shutdown message is issued if the reading for this temperature
sensor was to its upper or maximum range (out of range).
Digital Board 1-10 Port 3-4 Reset (Zones 1 - 30) - If a reset
of this Digital Board and port occurs, a shutdown will result.
Fan Auxiliary Shutdown (Zone 1 – 30)
Humidity Sensor Fault (Zone 1 – 30) - This shutdown mes-
sage is issued if the Humidity reading was to the upper or
maximum range (out of range) for its sensor.
High Humidity Warning (Zone 1 – 30) – The Humidity was
equal to or greater than the High Humidity Warning setpoint
for its time delay.
High Temperature Warning (Zone 1 – 30) - The Temperature
was equal to or greater than the High Temperature Warning
setpoint for its time delay.
Smoke Detector Shutdown (Zone 1 – 30) - This shutdown
message is issued if the Smoke Detector reading was to the
upper or maximum range (out of range) for its sensor.
Low Temperature Warning (Zone 1 – 30) - The Temperature
was less than or equal to the Low Temperature Warning set-
point for its time delay.
Max Days Between Defrosts Exceeded Warning (Zone 1 –
30)
Process Stopped (Zone 1 – 30) - One of the control program
subroutine processes has stopped functioning and a message
has been entered into the event log. This is a Warning mes-
sage.
Following is the alphabetical listing of all the possible alarms:
Ammonia Sensor Fault (Zone 1 – 30) - This indicates that a
shutdown has occurred, resulting from a failure of the Am-
monia Sensor.
Ammonia Shutdown (Zone 1 – 30) - The Ammonia level was
equal to or greater than the Ammonia Shutdown setpoint for
its time delay. MENU > SETPOINTS > SAFETY.
Ammonia Warning (Zone 1 – 30) - The Ammonia level was
equal to or greater than the Ammonia Warning setpoint for its
time delay. MENU > SETPOINTS > SAFETY.
Analog Board 1-5 Port 3-4 Comm. Shutdown (Zone 1 - 30)
- The Quantum™ LX controller is no longer able to communi-
cate to the Analog Board.
Auxiliary Analog Input #0-9 Low Shutdown (Zone 1 – 30)
- A unit Shutdown has occurred and message issued because
the input value to the Auxiliary Analog 0-9 input channel has
fallen below its Low Shutdown Setpoint value, and the Delay
for that setpoint has timed out. This setpoint is located by ac-
cessing MENU > SETPOINTS > AUXILIARIES > ANALOG INPUTS
> PAGE 1 or 2.
Auxiliary Analog Input #0-9 Low Warning (Zone 1 – 30) - A
unit Warning has occurred and message issued because the
input value to the Auxiliary Analog 0-9 input channel has fallen
below its Low Warning Setpoint value, and the Delay for that
setpoint has timed out. This setpoint is located by accessing
MENU > SETPOINTS > AUXILIARIES > ANALOG INPUTS > PAGE
1 or 2.
Auxiliary Analog Input #0-9 High Warning (Zone 1 – 30)
- A unit Warning has occurred and message issued because
the input value to the Auxiliary Analog 0-9 input channel has
exceeded its High Warning Setpoint value, and the Delay for
that setpoint has timed out. This setpoint is located by access-
ing MENU > SETPOINTS > AUXILIARIES > ANALOG INPUTS >
PAGE 1 or 2.
Auxiliary Analog Input #0-9 High Shutdown (Zone 1 – 30)
- A unit Shutdown has occurred and message issued because
the input value to the Auxiliary Analog 0-9 input channel has
exceeded its High Shutdown Setpoint value, and the Delay for
that setpoint has timed out. This setpoint is located by access-
ing MENU > SETPOINTS > AUXILIARIES > ANALOG INPUTS >
PAGE 1 or 2.
Auxiliary Digital Input #0-4 Warning (Zone 1 – 30) - A unit
Warning has occurred and message issued because the input
value to the Auxiliary Digital 0-4 input channel has not been
detected, and the Delay for that setpoint has timed out. This
setpoint is located by accessing MENU > SETPOINTS > AUXIL-
IARIES > DIGITAL INPUTS.
