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. A “Temperature Fault” will cause the “Fault Detected” message to flash
intermittently on the ITM display. The Modbus™ fault register bit for Temperature Fault will be set and will
not clear until the fault condition has been cleared. If a Temperature Fault occurs, the 4-20mA signal remains
operational.
AutoSpan Fault
If 180 days has elapsed since the last successful AutoSpan, an AutoSpan Fault will be generated.
An
“AutoSpan Fault” will cause the “Fault Detected” message to flash intermittently on the ITM display. The
Modbus™ fault register bit for AutoSpan Fault will be set and will not clear until the fault condition has been
cleared by executing a successful AutoSpan. If an AutoSpan occurs, the 4-20mA signal remains operational.
