MOUNTING, FUNCTIONING
CONNECTING
1. Disconnect the power supply from the
mains by the phase fuse, the circuit-bre-
aker or the switch-disconnector that are
joined to the proper circuit,
2. Check if there is no voltage on connec-
tion cables by means of a special mea-
sure equipment,
3. Install WZM-01 device in the switchboard
on TH-35 DIN rail,
4. Connect the cables with the terminals
according to installing diagram,
5. Switch on the power supply from the
mains,
6. Adjust the demanded switch on time by
means of a potentiometer.
The system works properly after switching
on the power supply from the mains. Turning the
potentiometer in the direction of „ ” causes the
lighting device to switch on at lower lighting level, in
the direction of „
☼
” causes the device to switch on
at higher lighting level. In case the inner sensor’s
luminous flux density falls below the preset thres
-
hold the system switches on the output relay and
its lighting devices. The relay is switched on until
the luminous flux density is over the preset thres
-
hold. Using the luminous flux density hysteresis
(delta) and relay switching off time delay (T) makes
the system resistant to momentary and accidental
sensor lighting. While mounting the twilight switch
pay attention the switched on lighting does not
disturb the functioning of the external light sensor.

Typical application:
The twilight switch operates the light control functions (e.g. garden lighting). The
light sensor should be installed in a place which is not directly illuminated by lights
that are operated by this twilight switch.
