Protection
The.electric.actuators.are.fitted.with.external.and.internal.protecting.terminal.for.securing.protection.against.
dangerous.shock.voltage..
The.protecting.terminals.are.marked.according.to.ČSN.IEC.417.
(34 5555).
The actuator must be properly secured against both overload and short circuit.

DMS2.or.DMS2 ED..Both.systems.scan.
position.of.the.output.shaft.and.torque.of.the.electric.actuator.by.contact-free.magnetic.sensors..Long.service.life.is.
guaranteed.for.the.contact-free.sensors.that.do.not.get.mechanically.worn.

(set parameter can be backed up on a computer)
.or.manually.without.a.computer.
(for the
electronics DMS2, parameters can be manually set and it can be checked without computer only if the system is
equipped with a display and local control).
