Installation/Operating Instructions for
Time Delay Switch
Part No: TLSN
Thank you for purchasing a quality time delay switch from GreenBrook. Please
read these instructions fully prior to initial use.
Every effort has been made to ensure that the guidance information on this
sheet will enable the installation of the switch to be carried out safely and
correctly.
THIS PRODUCT SHOULD BE INSTALLED BY A COMPETENT PERSON AND IN ACCORDANCE
WITH THE CURRENT IET WIRING REGULATIONS, AND BUILDING REGULATIONS.
The TLSN is suitable for controlling incandescent (GLS), fluorescent, and
compact fluorescent lighting. The timer can be used on its own, or with other
units in a 2-wire (no neutral) lighting circuit, and can therefore be
installed on new installations or replace existing single gang switches.
IMPORTANT
All metal boxes must be earthed.
Please ensure that the top and bottom lugs are removed, if fitted, from metal
wall boxes before fitting as there is a danger of the common terminal (marked
com) fouling a mounting lug and causing an earth fault if boxes having four
lugs are used.
INSTALLATION
The TLSN has been designed for mounting on a 20mm or 25mm deep standard BS
single gang accessory box. However, it is recommended that deeper boxes are
used where extra space is required for additional cables, for example when
looping in. Please ensure that there is adequate space for wiring.
It is recommended that if using molded backing boxes, please ensure that the
backbox only has two mounting lugs as certain manufacturers do not allow
adequate clearance for the Time Delay Switch terminal connections. Some molded
boxes also have two locating pips on the mounting face which can obstruct the
Time Delay Switch and prevent it from fitting flush. These will need to be
ground off.
If mounting on surfaces such as unplastered brickwork or the mounting box 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.
OPERATION
The switch is operated by pressing the plunger button. This will “make”. The plunger will gradually return to its original position during the time delay sequence, eventually returning the contacts to their original position. The face-plate is molded in a semi-translucent material and therefore it is normal to occasionally see a flash when the contacts “make” or “break”.
WIRING
The live feed should be connected to COM (common). Contacts are connected
when the plunger button is pressed and will stay connected for the period of
the time delay.
As these units are designed for lighting circuits, a neutral feed is not
required at the switch position.
To use the Time Delay Switch as a normal light switch type operation, connect
the “Live Feed” Wire into the COM Terminal, and the “Switched Live” wire
into the NO terminal.
Additional switches can be wired in parallel to control the same load (please
see diagram below).
WIRING DIAGRAM
TIMER ADJUSTMENT
The timing can be adjusted between 10 seconds and 10 minutes (approx) by turning the brass timing screw in the center of the plate on the back of the unit. Turning the timing screw clockwise will increase the time delay.
