AUMATIC mounted separately from the actuator, including plug/socket connector. Connecting
cables on request. Recommended for high ambient temperatures, difficult access, or in case
of heavy vibration during service

The control voltage of the reversing contactors is interrupted by operating the EMERGENCY
STOP button.

COM-AC. An interface cable is required for the standard infra-red programming interface.Programming software for PC
14) The lifetime depends on the load and the number of starts. A high starting frequency will rarely improve the modulating accuracy. To
reach the longest possible maintenance and fault-free operating time, the number of starts per hour chosen should be as low as permis-
sible for the process
15) Cable length between actuator and AUMATIC max. 100 m. Not suitable for version with potentiometer in the actuator. Instead of the
potentiometer, an RWG has to be used.
