Important information!
According to the switch value tables, wires 2 and 3 or terminals 2 and 3
should not receive H potential at the same time.
The holding torque is
not guaranteed with simultaneous H potential.
Holding torque
Actuator with unconnected cable end:
When applying an L signal to wire 2 of cable 2 and simultaneously an L sig-
nal to wire 3 of cable 2, the actuator receives a holding torque.
Actuator with Ex-e terminal box:
When applying an L signal to terminal 2 and simultaneously an L signal to
terminal 3, the actuator receives a holding torque.
Stopping the actuator
The actuator can be stopped at any position. Activation is identical to that of
the holding torque.
Left end position
When the left end position has been reached, the actuator is switched off via
an electromagnetic limit switch. The end position is set via the assigned con-
trol cam.
Actuator with unconnected cable end:
When the left end position is achieved, an H signal for evaluation purposes is
provided to the customer's programmable logic controller (PLC) via wire 4 of
cable 2.
Actuator with Ex-e terminal box:
When the left end position is achieved, an H signal for evaluation purposes is
provided to the PLC at terminal 4.
