Sensorless Safety Standstill Monitor


2-channel standstill monitoring of motors

The new DOLD safety standstill monitor LH5946 detects standstill of disconnected motors
independent of the rotating direction. It fulfils SIL 3 and PL e/SK 4 and is used to release a
solenoid locking switch or to activate a mechanical hold in brake, e.g. on woodworking
machines, machine tools, conveyor systems etc. This provides fast access to dangerous areas
of a plant for service and maintenance.

Reliable fire and system protection

Differential current monitor type B with pre-warning function

Early detection of insulation faults can prevent failure of compl ete electrical plants. Fault
current monitoring by measuring differential current is the ideal method for this application.
The monitoring requirement for today’s supply systems get more and more complex.
Electronic control of drives, switched power supplies and chargers or fluorescent lamps with
electronic ballast units can create DC fault currents in the case of earth faults. Standard
differential current monitors do not detect this type of faults.
