Off times for intermediate positions (pivot points): set
An off time can be defined for each pivot point.
If a pivot point is reached with the operation behaviour
Off time in OPEN
,
Off time
in CLOSED
or
Off time in OPEN & CL.
, the actuator controls generate a signal during
off time:
Operation pause active

Two-wire control
Conditions
●
<Additional inputs> or additional <parallel interface>
●
Operation mode
Remote
(Selector switch = position Remote control).
Characteristics
With the <Two-wire control> function, the actuator can be operated to end position
OPEN or CLOSED via one digital input.
Information
In this function, the actuator only reacts to commands via the input
OPEN / CLOSE
.
Other inputs to which the operation commands OPEN, STOP, CLOSE were assigned,
do not have any function.
Execute operation commands via digital input:
Designation of digital input
OPEN / CLOSE
(Wiring diagram designation:
OPEN/CLOSE
Default setting
●
Input
OPEN / CLOSE
= low level (0 V DC or input open):
Actuator runs in direction CLOSE.
●
Input
OPEN / CLOSE
= high level (standard: +24 V DC):
Actuator runs in direction OPEN.
Configuration of digital input
For the two-wire control, a digital input for the
OPEN / CLOSE
signal has to be
configured.
Required user level:
Specialist (4)
Device configuration M0053
I/O interface M0139
Digital inputs M0116
Example
Use input DIN 5 for signal
OPEN / CLOSE
:
Parameter:
Signal DIN 5 M0122
=
OPEN/CLOSE
Information
The logic for the digital inputs may be inverted. Depending on the parameter setting
(e.g.
Coding DIN 6 M0128
), the input is either
High active
or
Low active
. Default
setting is
High active
.
