Timeguard MLWTS - Manual (Page 7)

TEST MODE – 3 LEDS VISIBLE
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. Each time you are
detected the lamp will illuminate. Now stand still until the lamp extinguishes (this should
take approx. 5 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.
Angling the head downwards will reduce the detection area should a smaller range
be required.
SETTING UP FOR AUTOMATIC OPERATION – 3 SCROLLING LED’S VISIBLE
When walk tests are complete, the unit will be switch into Automatic Mode.
Simply cease movement within the detection area for approximately 60 seconds, ensure the
lamp is not illuminated. The unit will then switch to Automatic Mode, this is indicated by
the illumination of three scrolling LEDS in the top transparent area of the sensor head.
These LED’s will scroll from left to right during daylight and darkness.
The TIME setting controls how long the unit remains illuminated following activation and
after all motion ceases.
(See diagram G. 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.
The setting is best achieved by the procedure below:
(See diagram G. the Dusk adjustment knob is indicated by the ‘Moon’ and ‘Sun’ symbols).
Set the DUSK control knob fully anti clockwise. Wait until darkness falls.
When the ambient light level reaches the level of darkness at which you wish the lamp
to become operative (i.e.: at dusk) SLOWLY rotate the control in a clockwise direction
until a point is reached where the lamp illuminates. Leave the control set at this point.
At this position the unit should become operative at approximately the same level of
darkness each evening. Observe the operation of the unit. If the unit is starting to operate
too early (i.e. when it is quite light) adjust the control slightly anti-clockwise. If the unit
starts to operate too late (i.e. when it is very dark). Adjust the control slightly clockwise.
Continue to adjust until the unit operates as desired.
The LED’s will scroll from left to right, day and night; indicating the unit is in Automatic
Mode. The LED’s will extinguish when the PIR activates the light for as long as the lamp
is illuminated.
MASKING THE SENSOR LENS
To restrict the sensor coverage, preventing detection in unwanted areas, mask the sensor
lens using the masks provided in the accessory pack (see diagram H). For your information,
the top section of the lens covers long range detection, the bottom covers short range.
Similarly the left and right lens sections cover the left and right detection areas respectively.
MANUAL OVERRIDE MODE – SINGLE LED ILLUMINATED
The light can be switched on for longer time periods by use of the Manual Override Mode.
This can be activated at night by using the internal wall switch or circuit breaker.
Switch the internal wall switch/circuit breaker twice (off/on, off/on) within 2 seconds.
The unit will now illuminate continuously or until it is switched back into Auto Mode.
