operation on the label (Fig.4).
The N conductor terminals are only used for running time de-
tection purposes and are not at neutral potential.
If drives with high-impedance inputs are connected to the
device, the respective N conductor can be used. The output
concerned must not be activated without interruption for a
prolonged period by retriggering; this can cause inadmissible
heating of the device. Observe the maximum duty cycle (Tech-
nical Data).
Connecting the device with automatic running time detection
If programmed and connected accordingly, the shutter actuator de-
tects the running time of the individual blinds/shutters and stores
them. The actuator measures the voltage against the connected
N terminal at the drives and can thus recognize the limit positions.
In operation, the shutter actuator can adapt itself to changes in
the running times of the blinds/shutters that are due, for instance,
to ageing of the motors.
