bS
Event counter 2
Number underruns above
threshold
Maintenance alarm
The number of underruns of the process value (set in parameters "Lower
limit" and "Monitored value") has reached the threshold.
Reset and acknowledge event counter.
Check process conditions.
Check limit monitoring and event counter settings.
CA
Simulation mode
The device is in simulation mode and one or more of its device variables
are not representative of the process.
Disable the simulation to return to normal operation.
Cb
Diagnostics simulated
The device is in simulation mode.
Disable the simulation to return to normal operation.
Co
Loop current fixed
The loop current is being held at a fixed value and is not responding to
process variations.
Enter the loop current output value for simulation.
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.
CU
PV status: uncertain
The value is outside of the physical sensor range. Accuracy may decrease.
CY
PV status: bad
The measured value is 10% higher than the physical sensor range.
Review process conditions versus product specifications.
Use a device that fulfills your process conditions.
Fb
Supply voltage below limit. The supply voltage is too low.
Make sure input voltage is within product specification.
FC
Supply voltage above limit The supply voltage is too high.
Make sure input voltage is within product specification.
