Motorized Rotary Actuator baelz 375-E42
5.3.2 Switching off in end positions
Risk of electric shock!
Danger
If the switches in the actuator are not factory-wired, check proper switching off in end positions:
With the cover removed, the rotary actuator may only be operated briey for test runs or
when performing absolutely essential adjustments on electrical components, such as
potentiometer, limit switches or positioning electronics.
While performing this activity, there is unobstructed access to hazardous, live, exposed,
moving and rotating parts. Adjustments performed incorrectly or without exercising the
necessary caution may result in death, serious injury or substantial material damage.
Any operation of the rotary actuator with the cover removed for a purpose other than
that described above is prohibited.
Use an insulated screwdriver to actuate the switching rollers of the DE switches as shown in
the wiring diagram, Fig. 9, page 19, and check that the each switch actually switches off the
motor. If necessary, change the motor supply jumpers.
