Staircase time switch. 1 NO contact not potential free 16A/250V AC
Digital settable staircase time switch with switch-off early warning and permanent light by pushbutton switchable. Standby loss 0.5 watt only. With ESL optimisation and multifunction. The functions and times are entered using the MODE and SET keys as described in the operating manual and indicated on the LC display. A keylock function is provided. Zero passage switching to protect contacts and lamps. This prolongs in particular the lifetime of energy saving lamps. The noiseless electronics do not even bother the sensitive ear Â– unlike many synchronous motors with mechanical gears. By using a bistable relay coil power loss and heating is avoided even in the on mode. The switched consumer may not be connected to the mains before the short automatic synchronisation after installation has terminated. Control voltage, supply voltage and switching voltage 230V. In addition electrically isolated universal voltage from 8 to 230V UC. 3-wire and 4-wire circuits, resettable, with attic lighting if 4-wire circuit. Automatic detection of the method of connection. Glow lamp current up to 50mA, dependent on the ignition voltage of the glow lamps. Precise variable time range from 1 to 99 minutes. Separate continuous light pushbutton with projecting SET button in the functions STS, ISO, IS and R. With motion detector control input BM, which converts the input signal into a control impulse if the function STS is set.
