Single‐Acting Relays
WARNING
For Instrument Level ODV only:
If the unused port is monitoring pressure, ensure that the pressure source conforms to ISA Standard 7.0.01 and does not
exceed the pressure supplied to the instrument.
Failure to do so could result in personal injury or property damage caused by loss of process control.
Single‐Acting Direct Relay
The single‐acting direct relay is designated by “Relay C” on a label affixed to the relay itself. Relay C requires no
adjustment.
Single‐Acting Reverse Relay
The single‐acting reverse relay is designated by “Relay B” on a label affixed to the relay itself. Relay B is calibrated at the
factory and requires no further adjustment.
Restoring Factory Settings
Field Communicator Configure > Calibrate > Restore Factory Settings (1‐3‐4)
Note
After restoring factory settings you will need to re‐configure and calibrate the instrument.
Follow the prompts on the Field Communicator display to restore calibration and all parameters to the factory
settings. You should only restore the calibration if it is not possible to calibrate an individual sensor. Restoring
calibration returns the calibration of all of the sensors and the tuning set to their factory settings. Following restoration
of the factory calibration, the individual sensors should be recalibrated.
