Once the AC source rises above 104-volts, or below the 132-volt level the time delay indicator flashes for the preset time and then automatically restores power to RV.Time delay for Air Conditioning Compressor: Whenever power is interrupted to the EMS or a fault shuts the protector down the built in time delay is activated.
