ID Symbols Message Cause/Remedy
Co Loop current 󹪝xed The loop current is being held at a 󹪝xed value and is not responding to
process variations.
Disable the simulation to return to normal operation.
CP Loop current in saturation The loop current has reached its upper (or lower) saturation limit and
cannot increase (or decrease) any further.
Adjust loop current scaling.
E4 Internal RTD sensor error Sensor error is detected at the internal temperature sensor.
Reset the device or switch it o󹪜 and back on.
If the problem persists, contact Technical Support.
EL Electronics temperature alarm Device LED 󹪞ashing red: The device is operated outside its speci󹪝ed
temperature range.
Check the operating temperature.
Device LED lights permanently red: The device is operated outside
its speci󹪝ed temperature range in functional safety mode.
Check the operating temperature.
Fb Minimum supply voltage not
reached
Device LED is o󹪜: A supply voltage is probably applied but still too low.
Check the power supply (at the output terminals).
If the problem persists, contact Technical Support.
Device LED lights permanently red: The device is operated below its
speci󹪝ed supply voltage range.
Check the power supply (at the output terminals).
Reset the device or switch it o󹪜 and back on.
If the problem persists, contact Technical Support.
FL Electronics defect Defect of device electronics.
A replacement of the device is recommended.
Contact Technical Support.
Fn Error in communication with in‐
put CPU
An unrecoverable error occurred in the internal communication to the
input CPU.
Reset the device or switch it o󹪜 and back on.
If the problem persists, contact Technical Support.
FE Loop current read back error The loop current does not correspond to the expected value.
Check DAC trim settings.
Restore to factory DAC calibration.
If the problem persists, contact Technical Support.
