E1ZT

1. Functions

Electronic staircase lighting timer with switch-off warning. The control input allows the connection of pushbuttons with a total glow lamp load up to 100mA and enables the application in 3- or 4-wire circuits. The unit can be retriggered via the connected pushbuttons. A long keypress will switch off the light (energy saving function). A fast sequence of pushes (pumping) will extend the period to a multiple of the selected value. Depending upon distinct type, the following operating methods can be selected by the controls on the unit:

TW Automatic timer with switch-off warning T Automatic timer without switch-off warning 1 Steady light (ON) 0 Switch-off P

Impulse switch mode without time function (only types with option P)

Impulse switch mode power fail latch (only types with option PN)

Function sets on distinct types are according to table ordering information or printing on the unit.

Functions

Function automatic timer (T, TW): After the pushbutton at B1 has been

pressed, the output relay R closes (terminals L-18) and the set interval t begins. If the pushbutton is pressed again before the interval t has expired, the interval begins again (restart function complies with EN 60669-2-3). Rapid, multiple pressing of the pushbutton (pumping) adds 2, 3 or more time intervals to extend the time up to 60min. Prolonged pressure on the button (>2s) aborts the interval running and switches the relay off (energy saving function). In the TW mode the device provides a switch-off warning (in accordance with DIN 180-158-2) by generating

short pulses (ashing) at 30s, 15s and 5s prior to switch-off.

Operating possibilities at B1 in mode T and TW:

Connections

3-wire-circuit

4-wire-circuit with attic illumination

The additional control input C1-C2 can be used in the T and TW modes to control the staircase lighting timer with a voltage of 8 to 230V AC/DC. This input can be used to start and restart the cycle. It cannot be used for switchoff (energy saving function) or for programming long intervals (pumping).

Impulse switch mode (P), (PN): n this mode, every keypress toggles

the output relay R (ip-op). In function P, the output relay R remains in

off-position, whenever the supply voltage is applied. In function PN, the

Dimensions

output relay R switches into on-position after applying the supply voltage U, if the output relay R was in on-position last before power failure. The output relay R switches into on-position, if a short voltage impulse (<2s) is applied to the additional control input (C1-C2). (central ON) A longer voltage impulse (>2s) opens the output relay R. (central OFF)
