PRODUCT DATA AND INSTALLATION SHEET
ELLIPSE AND KH2 ELECTRONIC
TIME LAG SWITCHES The ELLIPSE and KH2 time lag switches are a quick and effective
way to reduce energy consumption for lighting applications. Press-
ing the button or touch pad brings the lights on; the lights will then
switch off automatically after a preset time period has elapsed.
These units do not require a neutral connection, therefore they can
be used to replace an existing light switch. The duration of the time
delay is set by a thumbwheel on the reverse of the unit.
The ELLIPSE/TN and KH2N have neon illumination to allow the
unit to be located in the dark.
Time lag switches can be used in two way and intermediate switch-
ing arrangements without any extra wiring.
DESCRIPTION AND OPERATION
WIRING
Warning. This device works at mains potential. Be sure to take care when
working with electricity.
1. Make sure the load is connected and in working order.
2. Isolate the mains supply to the circuit at the main consumer unit.
3. Connect the controller via the terminal block. Live supply to the L
terminal and the load to the LIVE OUT terminal.
4. Push the override switch to the off position (see diagram).
5. Set the timing range using the thumbwheel. Turn clockwise to
increase timing.
6. Screw the unit to the wall and switch the mains supply back on at
the distribution board.
7. Wait 20 seconds before pushing the button
8. Push the button or touch pad and the lights will come on
9. Wait for the time period and the lights will turn off again.
INSTALLATION
Conventional Wiring
Wire the units as in diagram 1. When using multiple switch posi-
tions see diagram 2.
For two way and intermediate switching follow the diagrams over-
leaf. Note that as long as each switch position has a Live feed
and a Live Out connection to the load then the switch will be
properly wired.

LOAD
10A of lighting including incandescent, fluorescent, compact fluorescent, low voltage (switch
primary of transformer).
Fluorescent and compact fluorescent fittings with “switch start” ballasts - 10 ballasts maximum.
Power factor correction capacitors must be fitted.
Most fluorescent fittings have power factor correction capacitors fitted. If they are not present
the unit may fail to turn off properly or flicker. In this case fit one capacitor per circuit with a
minimum value of 1μF for every unit installed. The capacitor should be fitted across switched
live and neutral. Note that it is not necessary to fit a capacitor on every fitting. This also applies
to fittings controlled with high frequency ballasts and maintained emergency fittings.
Not suitable for switching contactors
Not suitable for SON lighting
Not suitable for heating or ventilation loads.

LIGHTS DO NOT COME ON
Check to see if the live supply to the circuit is
good. Strap across the L and LIVE OUT termi-
nal to turn the load on.
LIGHTS DO NOT GO OFF
Ensure that you have waited for the time out
period.
If the lights still do not go off then it is likely the
unit was not given the 20 seconds start up pe-
riod on installation. Follow this procedure:
1. Isolate the mains supply to the circuit at
the main consumer unit and unscrew
the unit from the wall.
2. Push the override switch to the off posi-
tion.
3. Reapply the mains and wait for 20 sec-
onds.
4. Activate timer as normal.
LIGHTS FLICKER
Ensure that there are sufficient power factor
correction capacitors fitted.
