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: + 24 V 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).

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
EMERGENCY position (i.e. end position OPEN or end position CLOSED). During
EMERGENCY operation, the actuator does not react to other operation commands
such as Remote OPEN/Remote CLOSE, Remote SETPOINT, Fieldbus
OPEN/Fieldbus/CLOSE or Fieldbus SETPOINT.
