PRM_5535 Selector
Or directly via the tool bar in the “Device”tab in PRM_5535 Selector or Remote
control.
Default setting: Operation mode = REMOTE
Information The actuator only reacts to the currently selected command source. However, the
command source can be changed during running operation.The OPEN/CLOSE
operation is usually performed via the digital inputs.The setpoint control (e.g.for
modulating duty) can only be performed via the analogue inputs or the fieldbus.
Change-over between OPEN-CLOSE control and setpoint control
For PROFOX actuators, it is possible to select between OPEN - CLOSE control
(REMOTE OPEN-CLOSE) and setpoint control (REMOTE SETPOINT).
For the change-over, a digital input must be available and configured for the PZD_22
MODE signal.
●PZD_22 MODE input = high level (default:+ 24V DC) = Remote OPEN-CLOSE
Control is made via binary OPEN, STOP, CLOSE commands.
●PZD_22 MODE input = low level (0 V or input open) = REMOTE SETPOINT
Control takes place via an analogue signal (e.g. 0/4 –20 mA).
Change-over between fieldbus control and OPEN-CLOSE via I/O signals (for
actuators with fieldbus interface)
As standard, the actuator is supplied with fieldbus and digital signals.A digital input
is used to define which source is active, this means whether the actuator is controlled
via fieldbus or via I/O signals. It is not possible to use both sources to active
simultaneously.The PRM_926 Signal DIN 3 signal is assigned to PZD_275 I/O
interface as factory setting:
Not live (= 0V) means that control is made from REMOTE via fieldbus.
Live (= 24V) means that control is made from REMOTE via binary I/O signals.
Commands for the operation function:
OPEN/CLOSE operation commands can be issued via fieldbus or a setpoint can be
sent for any position.Change-over is made via the PZD_332 Fieldbus SETPOINT
command.
●Setpoint control:
Fieldbus SETPOINT command bit = 1 = REMOTE SETPOINT
The actuator reacts to the setpoint E1 transmitted via the fieldbus.
●OPEN - CLOSE control:
Fieldbus SETPOINT command bit = 0 = REMOTE OPEN-CLOSE
Actuator can be operated via Fieldbus OPEN/Fieldbus CLOSE command bits
in direction OPEN or CLOSE.
Configuration of digital input
Required user level:Specialist (4).

Example: Use Signal DIN 1 input for change-over:
Parameters: PRM_873 Signal DIN 1
Setting value: MODE

EMERGENCY operation
An EMERGENCY operation is triggered by a signal at EMERGENCY input or the
Fieldbus EMERGENCY command bit.The actuator moves to a predefined
