Configuration Protection

To setup and calibrate the instrument, the protection
must be set to None with the Field Communicator. If
the protection is not None, changing the protection
requires placing a jumper across the Auxiliary
terminals in the terminal box.
To remove protection:
1. Connect a 4-20 mA source to the instrument.
2. Connect the Field Communicator to the instrument
and turn it on.
3. Press the Hot Key on the Field Communicator and
select Protection.
Note
If the Aux Terminal Mode is configured
for Auto Calibration, be sure the
jumper remains across the auxiliary
terminals until the Field Communicator
prompts you to remove it. Removing
the jumper too soon will cause the
instrument to begin auto calibration.
Auto calibration can be terminated by
shorting the Aux Terminals for one
second.

WARNING
If the jumper is removed too soon,
and auto calibration begins, the valve
will move full stroke. To avoid
personal injury and property damage
caused by the release of pressure or
process fluid, isolate the valve from
the process and equalize pressure on
both sides of the valve or bleed off
the process fluid.
4. From the Protection menu, select None. When
prompted by the Field Communicator, temporarily
attach the jumper to the AUX + and AUX − terminals
in the instrument terminal box.
