Digital output

The alarms generated in the positioner can be polled via the

digital output as a collective alarm.

The desired information can be selected via the operator panel

or remotely via the configuration program.

The output can be set to “active high” or “active low”, as

required.

Digital input

For the digital input, one of the following safety options can be

selected. You may use the operator’s panel or configuration

program to select an option.

— No function (default)

— Move to 0 % position

— Move to 100 % position

— Hold previous position

— Disable local configuration

— Disable local configuration and operation

— Disable any access (no local or remote access via a PC)

The selected function is activated when the 24 V signal is no

longer connected to the digital input (< 11 V DC).

Switching points for the position

You can use these parameters to define two position limits for

signaling (see option “Module for digital position feedback”).

Digital output

The alarms generated in the positioner can be polled via the

digital output as a collective alarm.

The desired information can be selected via the operator panel

or remotely via the configuration program.

The output can be set to “active high” or “active low”, as required.

This parameter can be set separately for each end position.

When the respective configured limit value is exceeded, the

shut-off function causes immediate travel of the actuator until

reaching the set end position.

If the value “0” is entered for the corresponding parameter, the

position is further controlled, even in the respective end

position.

Shut-off function

This parameter can be set separately for each end position.

When the respective configured limit value is exceeded, the

shut-off function causes immediate travel of the actuator until

reaching the set end position.

If the value “0” is entered for the corresponding parameter, the

position is further controlled, even in the respective end

position.

Travel time prolongation

This function can be used to increase the max. travel time for

full travel. This time parameter can be set separately for each

direction.

This function can only be used with the pneumatics with the

safety function “fail-safe”.

Switching points for the position

You can use these parameters to define two position limits for

signaling (see option “Module for digital position feedback”).

The positioner has a local communication interface (LCI) as

standard. Additionally, a “HART communication” option for

communication via the 20 mA signal is available. Both

communications are based on the HART Protocol.

Alternatively, HART5 or HART7 are available.

Inputs / Outputs

In addition to its input for the analog position setpoint, the

positioner is equipped with a digital input which can be used

to activate control system functions in the device. A digital

output allows you to output collective alarms or fault messages.

Modular design

The basic model can be enhanced at any time by retrofitting

optional equipment.

Option modules can be installed for analog and digital position feedback.

Additionally, a mechanical position indicator, proximity

switches or 24 V microswitches are available for indicating the

position independently of the mother board function.

Use

The positioner has a built-in operating panel providing a 2-line

LCD display and 4 operating buttons for commissioning,

configuration and monitoring during live operation.

Alternatively, the appropriate configuration program can be

used via the available communication interface.
