5. Troubleshooting Guide
5.1 Fault Codes
If the ITM detects any functional errors the ITM will bring the mA output to 0mA and hold it there until the
problem has been resolved. If the unit has a Display, the display will show an error code. Error codes are
displayed as “Fxx” where xx is the actual error code.
The Display Error Codes are:
F01 Span
Fault
F02 Temperature Fault
F03 4-20mA Fault
F04 Input Voltage Fault
F05 ITM Memory Fault
F06 Processor Fault
F07 Clearing Fault
F08 Stability Fault
F09 Range Fault
F10 Sensor Fault
F11 Zero Fault
F12 Sensor Fault 2
CF Communication Fault
F01 – Auto Span Fault
If the sensor fails the minimum signal change criteria during a span calibration an “Span Fault” is declared,
and ‘F01’ will be displayed. This is normally a calibration error. The sensor should be considered “Out-of-
Service” until a successful span calibration is performed.
F02 – Temperature Fault
If the detector is currently reporting an ambient temperature that is outside of the –40C to +75C range, a
“Temperature Fault” is declared, and the display will change to ‘F02’. If a Temperature Fault occurs, the 4-
20mA signal remains operational.
F03 – 4-20mA Fault
If the sensor detects a condition where the 4-20mA output loop is not functional (high loop resistance or failed
circuit function) a “4-20mA Fault” is declared, and ‘F03 will be displayed. If a 4-20mA Fault occurs, the 4-
20mA signal will be set to 0mA until the fault condition is resolved.
F04 – Input Voltage Fault
If the detector is currently receiving an input voltage that is outside of the 10-28VDC range, an “Input Voltage
Fault” is declared, and ‘F04’ will be displayed. If an Input Voltage Fault occurs, the 4-20mA signal will be set
to 0mA until the fault condition is resolved.
F05 – ITM Memory Fault
If the detector has a failure in saving new data to memory, a “Memory Fault” is declared, and ‘F05’ will be
displayed. If a Memory Fault occurs, the 4-20mA signal will be set to 0mA until the fault condition is
resolved.
F06 – Processor Fault
If the detector has any unrecoverable run-time errors, a “Processor Fault” is declared, and F06 will de
displayed. If a Processor Fault occurs, the 4-20mA signal will be set to 0mA until the fault condition is
resolved.
