Error Message Indicators (any
display line)
Disab
Thermocouple
Indicates that the selected thermocouple (TC1, TC2, or TC3) is not
enabled through the menu options.
OPEN
Thermocouple is
Open or Failed
Open
Indicates that a thermocouple is not connected or that it has failed in
an open condition.
If a thermocouple indicating "OPEN" is enabled, all solenoid valve
outputs will not open and the CSC400 system will not start until the
thermocouple "OPEN" condition is fixed.
Uncal
Indicates that the CSC400 Controller's thermocouples are
uncalibrated.
Seen if the internal thermocouple calibration procedure failed.
Indicators (Shutdown line
PilF 1
Output Fail, IGN1
IGN1's Pilot solenoid output has failed but it's supposed to be open.
ie: no output voltage is present on the Pilot + terminal
P1 Fault
Solenoid Fault -
Pilot, IGN1
There has been a fault on IGN1's Pilot Solenoid output due to a short
circuit or excessive current draw on the Pilot + terminal (to ground).
M1 Fault
Main, IGN1
There has been a fault on IGN1's Main Solenoid output due to a short
circuit or excessive current draw on the Main + terminal (to ground).
TM1 Fault
TMain, IGN1
There has been a fault on IGN1's T/Main Solenoid output due to a
short circuit or excessive current draw on the T/Main + terminal (to
ground).
PilF 2
Pilot Solenoid
Output Fail, IGN2
IGN2's Pilot solenoid output has failed but it's supposed to be open.
ie: no output voltage is present on the Pilot + terminal
P2 Fault
Pilot, IGN2
There has been a fault on IGN2's Pilot Solenoid output due to a short
circuit or excessive current draw on the Pilot + terminal (to ground).
M2 Fault
Solenoid Fault -
Main, IGN2
There has been a fault on IGN2's Main Solenoid output due to a short
circuit or excessive current draw on the Main + terminal (to ground).
TM2 Fault
TMain, IGN2
There has been a fault on IGN2's T/Main Solenoid output due to a
short circuit or excessive current draw on the T/Main + terminal (to
TC1 F
Intermittent Pilot
TC1 has shut off power to the ignition module in Intermittent Pilot
mode due to a fault condition on thermocouple 1.
4201 OPN
Open
Indicates that the 4-20mA Input 1 is Open. A Shutdown has been
triggered and all Ignitors and output solenoids are turned off.
If "Lo Alarm" or "Hi Alarm" are Enabled in the 4-20mA Input 1
settings, the 4-20mA Input 1 has been detected as being open.
4202 OPN
Open
Indicates that the 4-20mA Input 2 is Open. A Shutdown has been
triggered and all Ignitors and output solenoids are turned off.
If "Lo Alarm" or "Hi Alarm" are Enabled in the 4-20mA Input 2
settings, the 4-20mA Input 2 has been detected as being open.
R9Fail
relay) output
Indicates that there is an internal error with the 12VDC voltage level.
This message may show briefly during normal operation timing. If
condition persists, contact ACL for details.
