Using sensor simulation for troubleshooting

When sensor simulation is enabled, the transmitter reports user-specified values for basic
process variables. This allows you to reproduce various process conditions or to test the
system.
You can use sensor simulation to help distinguish between legitimate process noise and
externally caused variation. For example, consider a receiving device that reports an
unexpectedly erratic density value. If sensor simulation is enabled and the observed
density value does not match the simulated value, the source of the problem is likely to be
somewhere between the transmitter and the receiving device.
Sensor simulation requires an Enhanced Core and a communication device.
Important
When sensor simulation is active, the simulated value is used in all transmitter outputs and
calculations, including totals and inventories, volume flow calculations, and concentration
calculations. Disable all automatic functions related to the transmitter outputs and place the loop in
manual operation. Do not enable simulation mode unless your application can tolerate these effects,
and be sure to disable simulation mode when you have finished testing.

Check mA Output Fault Action

mA Output Fault Action controls the behavior of the mA output if the transmitter
encounters an internal fault condition. If the mA output is reporting a constant value
below 4 mA or above 20 mA, the transmitter may be in a fault condition.

Configuration and Use Manual
Choose Service Tools > Verification and Calibration > mA Output Trim.
Follow the instructions in the guided method.
Check the trim results. If any trim result is less than −20 microamps or greater than
+20 microamps, contact customer service.
Record your current process conditions.
Check the configuration of the LRV and URV.
Check the status alerts for active fault conditions.
If there are active fault conditions, the transmitter is performing correctly. If you
want to change its behavior, consider the following options:
• Change the setting of mA Output Fault Action.
