Push-to-run operation or self-retaining Remote

After an operation command in direction CLOSE, the actuator continues to run, even
if the operation command is cancelled (self-retaining). The actuator is either stopped
by the STOP command or if end position CLOSED or an intermediate position CLOSE
has been reached.
In directions OPEN and CLOSE = self-retaining:
After an operation command, the actuator continues to run in directions OPEN or
CLOSE, even if the operation command is cancelled (self-retaining). The actuator
is either stopped by the STOP command or if an end position or intermediate position
has been reached.
Direct reversal of operation is not possible. Operation commands in directions OPEN
or CLOSE must be stopped first by STOP command. Only then is an operation
command into the opposite direction allowed.
In directions OPEN and CLOSE = self-retaining without stop:
Direct reversal of operation is also possible without the STOP command. However,
operation can be stopped at any time by the STOP command.
Hold down push buttons
ate self-retaining, press STOP to reset the operation mode to push-to-run operation.
Selector switch is in position Remote control (REMOTE).
The indication in the top row of the display shows the set source of the operation
commands:
Remote (parallel interface)
Remote II (parallel interface, push button station)
Depending on the control, a distinction is made between:
OPEN - CLOSE control (operation mode Remote OPEN - CLOSE):
Control is made via binary operation commands OPEN, STOP, CLOSE.
(or for activated Multiport Valve function via operation commands CW, CCW)
Setpoint control (operation mode Remote SETPOINT):
Control via analogue operation commands, e.g. 4 – 20 mA.
Binary signals (e. g. +24 V DC) via digital inputs are only recognised as valid
operation commands if the signal is present for at least 10 ms.
If a positioner or process controller is available, change-over between OPEN -
CLOSE control (operation mode Remote OPEN - CLOSE) and setpoint control
(operation mode Remote SETPOINT) is possible. Refer to chapter <Change-
over between OPEN - CLOSE control and setpoint control>.
Parameters Self-retaining Remote M0100, Self-retaining M01193 and Self-retaining
Remote II M0101 determine the actuator operation behaviour to binary operation
commands (OPEN, STOP, CLOSE or CW, CCW), which control the actuator from
Remote" via I/O interface.
