P-manual mode

(as-delivered condition)

The “P-manual mode” is preset for the positioner in the

as-delivered condition. The digital display of the positioner shows

the current potentiometer position in the upper line. “NOINI”

blinks in the second line of the digital display. You can move the

actuator using the decrement and increment buttons. Switch to

Configuration” and “Initialization mode” to adapt the actuator as

per the positioner.
Alarms or position feedbacks can be triggered only after

initializing the positioner completely.

Configuration and initialization mode

To get to the “Configuration” mode, press the operating mode

button for at least 5 seconds. You can use the “Configuration”

mode to adjust the positioner individually as per your actuator

and start commissioning or initialization. The positioner reports

the “Configuration” mode with a configurable fault message. A

position feedback or display of limits A1 and A2 is not possible.

Note: If electrical auxiliary power supply fails when configuring,

the positioner responds as follows until the power supply is

reestablished:

• The positioner switches to the first parameter.
• Settings of the values already configured are retained.

In order to save the changed parameter values, exit the

“Configuration” mode or switch to another parameter. When

the “Configuration” mode is restarted, the control in the digital

display switches to the last activated parameter.

Manual mode (MAN)

You can move the actuator using the decrement and increment

buttons in this mode. The setting selected here is retained

irrespective of the setpoint current and leakages, if any.

Note: To accelerate the actuator movement keep one of the

two direction buttons pressed and simultaneously press the

remaining direction. In the event of a failure of the power

supply, once the power is reestablished the positioner switches

to “Automatic” mode.
