mined safety set point when the

positioner is in automatic mode

(AUTO). This function is not performed in

the manual mode

(MAN) or fail-safe

position mode (SAFE).

Switch AUTO/MANUAL

The positioner changes from the auto-

matic mode

(AUTO) to the manual

mode

(MAN) or vice versa.

This function is not performed if the

positioner is in the fail-safe position

mode (SAFE).

Start data logger

The data logger starts recording when

the binary input is activated (refer to Op-

erating Instructions EB 8389-1 EN on

EXPERTplus Valve Diagnostics).

Reset diagnostics

Active tests and monitoring are stopped

and the diagnostic data is reset once.

Additionally, the external solenoid valve

function can be selected if a non-floating

contact is configured:

External solenoid valve

The voltage for an external solenoid

valve is connected in parallel to terminals

+81/–82. This allows the switching state

of the solenoid valve to be monitored.

Note:

The optional binary input can only be

configured using the operator software e.g.

TROVIS-VIEW 4. The switching state is

transmitted when the switch is closed by de-

fault.

External position sensor

In this version, only the sensor is mounted to

the control valve. The positioner is located

separately from the valve.

The connection of controlled variable (x) and

output variable (y) signals to the valve is es-

tablished by cable and piping for air.
