Green Brook TLS Manual

Thank you for purchasing a quality time delay switch from Green rook. Please read
these instructions fully prior to initial use.
Every effort has een made to ensure that the guidance information on this sheet will
ena le the installation of the switch to e carried out safely and correctly.
IF IN DOUBT, INSTALLATION SHOULD BE
MADE BY A QUALIFIED ELECTRICIAN
IN ACCORDANCE WITH CURRENT
WIRING REGULATIONS.
The TLS is suita le for controlling incandescent (GLS), fluorescent and compact
fluorescent lighting. The timer can e used on its own, or with other units in a 2-wire
(no neutral) lighting circuit, and can therefore e installed on new installations or
replace existing single gang switches.
All metal oxes must e earthed.
Please ensure that the top and ottom lugs are removed, if fitted, from metal wall oxes
efore fitting as there is a danger of the common terminal (Marked Com) fouling a
mounting lug and causing an earth fault if oxes having four lugs are used.
The TLS has een designed for mounting on a 20mm or 25mm deep standard BS single
gang accessory ox. However, it is recommended that deeper oxes are used where
extra space is required for additional ca les, for example when looping in. Please ensure
that there is adequate space for wiring.
It is recommended that if using moulded acking oxes, please ensure that the ack ox
only has two mounting lugs as certain manufacturers do not allow adequate clearance
for the Time Delay Switch terminal connections. Some moulded oxes also have two
locating pips on the mounting face which can o struct the Time Delay Switch and
prevent it from fitting flush. These will need to e ground off.
If mounting on surfaces such as unplastered rickwork or the mounting ox is
completely true to the wall surface, please avoid over tightening the mounting screws,
as this may cause the switch faceplate to distort and in turn lock the plunger in the
“ON”position.

The switch is operated y pressing the plunger utton. This will “make” or “ reak” the
change-over contacts. The plunger will gradually return to its original position during the
time delay sequence, eventually returning the change-over contacts to their original
position using the snap action of the switch. The face-plate is moulded in a semi-
translucent material and therefore it is normal to occasionally see a flash when the
contacts “make” or “ reak”.

COM (Common) and NC (Normally closed) Contacts are connected when the timer is
off.COM and NO (Normally open) Contacts are connected when the plunger utton is
pressed, and will stay connected for the period of the time delay. As these units are de-
signed for lighting circuits, a neutral feed is not required at the switch position.
To use the Time Delay Switch as a normal lightswitch type operation, connect the “Live
Feed” Wire into the COM Terminal, and the “Switched Live” wire into the NO terminal.
Additional switches can e wired in parallel to control the same load.
(please see diagram elow)
Timer Ad ustment
The timing can e adjusted etween 10 seconds and 10 minutes (approx.) y turning
the Brass Timing Screw in the centre of the plate on the ack of the unit. Turning the
Timing screw clockwise will increase the time delay.
