Operating Principles

After the power is supplied to the controller and if the 'ON' command exists, the controller supplies full voltage to the system.
Providing the 'Energy Saving' contact is enabled, the programmed delay time will commence, which is fixed at approximately 6 minutes.
After the timer expires the LES-E is in 'Energy Saving' mode and the output voltage is reduced by approximately 25V or 20V according the customer requirement and order (e.g. if the input voltage is 232V, the output voltage will be 207V).  
In the case of power failure, after the power returns (restart), and all the control signals ('ON' & 'Energy Saving') are still present, the controller provides full voltage to the system and energy saving will begins after the time delay as mentioned above.
If, during energy saving mode, it becomes necessary to restart some or all lamps, this can be achieved by opening the connection to terminals 3 & 4 (disable 'Energy Saving' mode).
The unit will now supply full voltage until the 'Energy Saving' mode is again enabled via terminals 3 & 4 and the timer has elapsed.
