Timeguard NSLB150C - Manual (Page 7)

WaLK teSt PRoCedURe
The sensor will rotate from left to right, and tilt forward or backward. Adjust the sensor to
point in the required direction and angle down to limit forward range as required.
the unit can be set up in daylight or at night.
Set the time adjustment to minimum(fully anti-clockwise) and the light threshold to
maximum (fully clockwise) see diagram C.
Turn the power to the unit on. The lamp will illuminate for approximately 30 seconds. This
indicates the unit is wired correctly.
The unit is in Test Mode when the light turns off.
teSt Mode
The lamp will now illuminate for approximately 5 seconds every time movement is detected.
Walk across the detection area approximately 5 metres from the unit (see diagram B). each
time you are detected the lamp will illuminate. now stand still until the lamp extinguishes
(this should take approx. 5 seconds) and then for a further 2 seconds.
Start moving again, when you are detected again, the lamp will illuminate.
Repeat the above, walking at various angles and distances to the unit. This will help you to
establish the detection pattern.
if the detection area is too small for your requirements, try angling the sensor head up. This
will increase the detection area. Angling the head downwards will reduce the detection
area should a smaller coverage be required.

When walk tests are complete, the unit can be set up for Automatic Mode.
The TiMe setting controls how long the unit remains illuminated following activation and
after all motion ceases. (See diagram C, the time adjustment knob is indicated by the
"Clock" symbol).
The minimum time (fully anti-clockwise) is approx. 5 seconds, whilst the maximum time (fully
clockwise) is approx. 5 minutes. Set the control to the desired setting between these limits.
The DUSK control determines the level of darkness required for the unit to start operating.
(See diagram C). The DUSK adjustment knob is indicated by the "Moon" and "Sun"
symbols).
Set the light threshold to maximum (fully clockwise/Sun end), then turn the control anti-
clockwise about three quarters of the way round to the Moon end. This will give operation
after DUSK approximately.
For a more accurate setting of the DUSK control turn it fully anti-clockwise (Moon end) and
leave for at least 20 seconds for the unit to settle.
When the ambient light level reaches that required for DUSK adjust the DUSK control a
small amount clockwise pausing to try to get the unit to detect and turn the lights under
control On by moving a hand slowly backwards and forwards across the front of the
detector lens for around 5 seconds.
Continue to turn the control small amounts in a clockwise direction, stopping after each
adjustment to try to get the unit to detect as above.
eventually detection will occur and the DUSK level is now set as required.
