Staircase time switch, 1 NO contact 10A

1 NO contact not potential free 10A/250V AC. 230V LED lamps up to 600W, energy saving lamps ESL up to 200W, incandescent lamps up to 2000W. Switch-off early warning and permanent light by pushbutton switchable. Standby loss 0.7 watt only. With ESL optimisation. Built-in device for installation. 45mm long, 45mm wide, 18mm deep. Zero passage switching to protect contacts and 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. Control voltage, supply voltage and switching voltage 230V. With infinitely variable time range from 1 to 12 minutes. 50mA glow lamp current, dependent on the ignition voltage of the glow lamps. 3-wire and 4-wire circuits, resettable, with attic lighting if 4-wire circuit. Automatic detection of the method of connection. After a power failure the lighting is switched on again in case the set time has not elapsed yet. 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. When energy saving lamps ESL are completely or partially switched, then set the switch-off early warning with the pushbutton permanent light ESL on the lower rotary switch. If the function TLZ is selected the time can be extended within the first second after switching on or resetting by pressing the pushbutton repeatedly up to three times (incrementing). Each momentary-contact control increments the set time once. The function ESV, impulse switch with release delay up to 120 minutes, can be selected optionally. If this function is set it is automatically disconnected after the set delay is timed out if a manual OFF command has not been given. If the timing period is set to minimum in the function ESV, the release delay is switched off. The standard impulse switch function ES is then set.
