Staircase time switch. 1 NO contact not potential free 16A/250V AC
Staircase time switch with switch-off early warning and permanent light by pushbutton switchable. Standby loss 0.7 watt only. With ESL optimisation and multifunction. Zero passage switching to protect contacts and lamps. This prolongs in particular the lifetime of energy saving lamps. 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. In addition electrically isolated universal voltage. 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 30 minutes, settable by minute scale. Permanent light switch with the big rotary switch. If the function TLZ is set, the lighting is switched on again after a power failure provided the set time has not yet elapsed. With double connections for pushbutton and lamp in order to connect either above or below or only below. If switch-off early warning function is switched on, the light starts flickering approx. 30 seconds before time-out and is repeated three times at decreasing time intervals. If permanent light by pushbutton is switched on, permanent light can be switched on by pressing the pushbutton longer than 1 second. This is switched off automatically after 60 minutes or by pressing the pushbutton longer than 2 seconds. If both switch-off early warning function and permanent light by pushbutton are switched on, the switch-off early warning function is activated before the permanent light switches off.
