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)
D
Fuse against active feed at 20 mA
setpoint input
