Method of Operation

All EOM-B units are designed for installation within the contactor supply cable to the distribution boards of the lighting system.

(Input contactor should be installed before the controller)

The EOM-B is usually mounted next to, as far as is practicable, the lighting distribution board.

Protection

The supply and load are protected by suitably rated Miniature Circuit Breakers.

The EOM-B is equipped with thermal trips on the windings of the coils that will trip the supply on over temperature alarm.

Under and over voltage is a preset parameter of the microprocessor and will activate an alarm and in the case of under input voltage will prevent the unit from going into ‘Energy Saving’ mode.

The EOM-B is fitted with a Manual Bypass Switch.

OPERATING PRINCIPLE

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 6 minutes.

After the timer expires the EOM-B is in Energy Saving’ mode and the output voltage is reduced by approximately 10% (e.g. if the input voltage is 230V, the output voltage will be 205V).

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 enabled and the timer has elapsed.
