ÉCLAT SUB STATION INVERTERS AND CONTROLS (ESU)

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 INVERTER 105 PS INVERTER 205D ESU T , INVERTER 205P ESU T , INVERTER 116P ESU T  INVERTER 216P ESU T)

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 POWER FAILURE.

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 Unit.

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.
