Switching State; Electrical Connection - Fema DCM Série Mode D'emploi

3. Pressure limiters with mechanical interlock of the

switching state

Maximum pressure limiter ABC...-205
Minimum pressure limiter ABC...-206
Instead of the microswitch with automatic reset, a "bistable" microswitch is
installed in the limiters.
When the pressure reaches the value set on the scale, the microswitch
switches over and remains in this position. The catch can be relased by
pressing in the unlocking button (marked on the scale side of the switching
device by a red dot). The limiter can not be unlocked until the pressure has
decreased by a certain amount or, in the case of interlocking at the lower switching point, is
increased again. According to version, the interlock can be effective for a rising value
ABC ...-205 or for a falling value ABC...206.
