ÉCLAT SUB STATION INVERTERS AND CONTROLS
The ECLAT ESU
Inverters and Timers, provide Emergency
Lighting for Sub Stations which are usually positioned at some distance from the
respective Maintenance Personnel.
In the event of a Power Failure, the Emergency Lighting will
activate as per normal. However the rated Time Duration Period is cut short by
the Timer Unit. (the Time Period is adjustable; usually set at around 10
minutes.) When this Time Period has expired, the Emergency Lighting will
de-activate, placing the Inverters in Standby Mode. This is done to ensure that
the Emergency Luminaire Batteries are not depleted by the time Maintenance
Personnel arrive at the Sub Station, (which could take some time.) This is also
done to ensure that, in the event that there are persons present in the Sub
Station, they are not plunged into total darkness, and can find their way to the
Wall Mounted Timer Unit.
Upon arrival at the Sub Station, (or in the event that
persons are present) all that has to be done is to set the Timer to the required
time, (up to 2 Hour Duration; which can also be extended if required,) and push
the "Activate" Button. this will return the Emergency Lighting to Active Mode.
The ESU Mode of Operation will ensure that there is still
sufficient power in the Battery Packs to supply power to the Inverters and their
respective Lamps for approximately 98% of the Luminaires Rated Duration.
The Inverters will continue to run until, either, Mains Power
is restored, Low Battery Voltage Cut Off Voltage is achieved, or until the Set
Time has expired (whichever event occurs first.)
If the Mains Power is restored, the Inverters will switch to
Mains Mode and resume Charging of the respective Battery Packs and Mains
Monitoring for the next Power Failure.
If Low Battery Voltage Cut Off Voltage is achieved, the Timer
Unit will not re-activate the Inverters, as they will no longer be in Standby
Mode, but instead, in De Activated or Off Mode.
If the Timer Unit has timed out (if the Timer was set for
Short Duration; say 10 minutes,) the "Activate" Button can once again be pressed
to restore the Emergency Lighting. This is provided that there is sufficient
Power in the respective Battery Packs.
The entire range of ECLAT Inverters can be utilized for the
purpose of ESU. Up to 20 Inverters or Luminaires can be catered for within the
same Sub Station. (See INVERTER 105 DS

IN THE EVENT OF NO TIMER BEING REQUIRED, A SIMPLE ON / OFF
SWITCH CAN BE UTILIZED FOR OPERATING THE EMERGENCY LIGHTING. THIS ALLOWS FOR THE
INVERTER AND ASSOCIATED LAMP TO REMAIN IN THE STANDBY MODE, IN THE EVENT OF A
Upon entering the Sub Station, the Maintenance Personnel can
then Manually Switch the Emergency Luminaires from Standby Mode to Active Mode,
utilizing this Switch. This will allow the Emergency Luminaires to remain On or
Active, for their Full Rated Emergency Duration, or, until Mains Power is
restored, or, the Low Battery Cut off Voltage is reached.
It is however, very important to remember with this Option,
to switch the Emergency Lighting Switch back to Standby Mode upon departure from
the Sub Station. This function is usually carried out automatically by the Timer
With respect to Additional Wiring, over and above the normal
4 Wires for Standard Emergency Maintained Luminaires, or 3 Wires for Standard
Non-Maintained Luminaires: -
For the option without the relevant Timer Unit, an additional
2 Wires are required. These 2 Wires are parallel connected to each Emergency
Luminaire. Polarity of this additional wiring however, is most important.
For the option with the relevant Timer Unit, this is usually
set up in a "Master and Slave" Luminaire arrangement. An additional 4 Wires are
required between the "Master" Luminaire and the Timer Unit, and an additional 2
wires are required between the Timer Unit and each subsequent "Slave" Luminaire.
