Staircase light delay switch, 1 normally open contact not potential-free 16A/250V AC, 230V LED lamps up to 400W, incandescent lamps up to 2000W, off-delay with switch-off warning and push-button permanent light can be switched on. Also for energy-saving lamps ESL up to 200 watts. Bidirectional. Standby loss only 0.2 watts. Modular device for mounting on DIN-EN 60715 TH35 mounting rail. 1 division unit = 18mm wide, 58mm deep. Connection to the Eltako RS485 bus. Cross-wiring of bus and power supply with jumper. Switching voltage 230V. Contact switching at zero crossing to protect the contacts and consumers. If the supply voltage fails, the switching state is retained. When the supply voltage returns, the time period begins, at the end of which the device is switched off. In addition to the bus control input, this staircase light delay switch can also be controlled locally with a conventional 230V control button. Glow lamp current up to 5mA, depending on the ignition voltage of the glow lamps. The upper rotary switch LRN is required for programming. The release delay is then set here from 1 to 30 minutes. The middle rotary switch is used to program radio buttons and/or radio motion brightness sensors FBH in the LRN position, including one or more central control buttons. The desired function of this staircase light delay switch is then selected with this: NLZ = delay switch with adjustable response delay. TLZ = staircase light timer. ESL = staircase light timer for ESL energy-saving lamps. + button permanent light = with button permanent light (TLZ only). + switch-off warning = with switch-off warning (TLZ + ESL). + Push button permanent light and switch-off warning = with push button permanent light and switch-off warning (TLZ + ESL). When the push button permanent light is switched on, you can press the button for longer than 1 second to set the light to permanent, which switches off automatically after 60 minutes, or you can press the button for longer than 2 seconds to switch it off. When the switch-off warning is switched on, the lighting flickers around 30 seconds before the time expires and a total of 3 times at increasingly shorter intervals. If the switch-off warning and push button permanent light are switched on, the switch-off warning only occurs after the permanent light is switched off. With the lower rotary switch, a response delay (AV time) can be set for NLZ when controlled with a switch. Position AUTO1 = 1s, AUTO2 = 30s, AUTO3 = 60s, AUTO4 = 90s and AUTO5 = 120s (right stop). You can also set the light to permanent manually here. If, however, NLZ is controlled with a button, the lighting is switched on when the button is pressed for the first time, and the time period only begins when the button is pressed for the second time, at the end of which the lighting is switched off. If wireless motion-brightness sensors FBH are taught in, the switching threshold is set for the last FBH taught in, at which the lighting switches off or on depending on the brightness when motion is detected.The release delay that can be set on the FTN14 is extended by the time of 1 minute set in the FBH. If wireless window/door contacts FTK are programmed, either an opener or a closer is programmed. Accordingly, the timing begins when the window or door is opened or closed. If switches are programmed for continuous operation, e.g. with wireless transmitter modules or FTS14EM, they are switched on when pressed and the time only starts when the button is released. The LED under the upper rotary switch accompanies the programming process in accordance with the operating instructions and indicates control commands during operation by flashing briefly.
