Timeguard MLB98 - Manual (Page 5)

The TIME setting controls how long the unit remains illuminated following activation and
after all motion ceases.
(See diagram E 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 E. 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.
MASKING THE SENSOR LENS
To restrict the sensor coverage, preventing detection in unwanted areas, mask the sensor
lens using the masking label provided in the accessory pack (see diagram F). 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 (on/off, on/off) within 2 seconds. The
unit will now illuminate continuously until dawn or until it is switched back into Auto
Mode.
To switch the unit back into Auto Mode, flick the internal wall switch/circuit breaker off/on
once within 1 second. The unit will return to Auto Mode.
HOLIDAY MODE - SINGLE LED FLASHING
The benefit of Holiday Mode is that the user can program the unit automatically illuminate
for a certain time, (1- 8 hours) each night. At dusk the unit will illuminate for this set period
after which it will extinguish. The unit will continue to operate normally when it senses
movement until dawn. At dusk the following night the process will be repeated, the unit
will remain on for this set period
(1 - 8 hours) then operate as a PIR unit until dawn.
HOLIDAY MODE
Switch the internal wall switch/circuit breaker 3 times (off/on off/on off/on) within 2
seconds.
The unit will now illuminate for a user defined time between 1 and 8 hours. The time can
be set by rotating the centre adjustment knob as required. (See diagram E, the adjustment
knob is identified by the letter T inside a circle.)
