Setting values for parameters, Self-retaining Remote M0100 and Self-retaining
Remote II M0101:
Push-to-run operation activated, self-retaining off:
Actuator only runs in directions OPEN or CLOSE while an operation command is
being received. The actuator stops if the operation command is cancelled.
In direction OPEN = self-retaining (in direction CLOSE push-to-run operation):
After an operation command in direction OPEN, 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 OPEN or an intermediate position OPEN
has been reached.
In direction CLOSE = self-retaining (in direction OPEN push-to-run operation):
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 CLOSE command or if end position CLOSED or an intermediate position
CLOSED 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 the 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 the operation direction without STOP command is possible.
Direct reversal of operation is also possible without the STOP command. However,
operation can be stopped at any time by the STOP command.

The indication in the top row of the display shows: EMERGENCY
The operation mode EMERGENCY is initiated by the EMERGENCY signal.
The actuator performs an EMERGENCY operation. For example, the actuator
moves to a predefined EMERGENCY position (i.e. end position OPEN or end
position CLOSED).
As long as the EMERGENCY signal is present, the actuator does not respond
to any other operation commands (EMERGENCY signal has top priority).
The actuator can start immediately when switching on!
Risk of personal injuries or damage to the valve.
Ensure that the EMERGENCY signal is present when switching on.
Should the actuator start unexpectedly: Immediately set selector switch to pos-
ition 0 (OFF).

An EMERGENCY stop button (latching) is either located on the electrical connection
or outside.
The indication in the top row of the display shows: EMCY stop
In an emergency, the EMERGENCY stop button can be used to interrupt the
power supply of the motor control (contactors or thyristors).
Operation mode EMERGENCY stop supersedes all other operation modes.
