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.
