26 PME120-AI / PME120-AN (Contrac) ELECTRICAL ROTARY ACTUATOR | SEI/PME120-EN REV. A
... 8 Electrical test values

Test values (Brake and Motor)

Brake voltage

DC 135 V with AC 115/AC230 V mains supply.

Motor voltage

Check for currents symmetry (i. e. with clip-on ammeter).

Winding resistance

Depending on the actuator version proceed as follows:
PME120-AI (integrated electronic unit)
A Mains fuse
B Spare fuse
C Heater fuse
(only for 25 °C Version)
Figure 36: Pin assignment
1. Remove the plug.
2. Remove the actuator hood with electronics.
3. Check pins at pin carrier,Refer to pin carrier in Figure 36.
