2.5 Control box
The EBR-M1 control box, controls and monitors the forced draught burner. The microprocessor-
controlled program sequence ensures maximum stability of time periods, regardless of uctuations
in the power supply or ambient temperature.
The design of the control box protects it from the effects of ame outs. Whenever the supply
voltage drops below its rated minimum level (170 ± 8 V), the control box shuts down - even in the
absence of a fault signal.
The control box switches itself back on again once the voltage has exceeded the 190 ± 8 V.
