Technical requirements
♦In automatic gear, when the common power supply is under voltage, over voltage, loss of voltage, switch to standby power; when the standby power supply has the same fault, switch to double points position, the display shows automatic and alarm at the same time.
The LCD screen protects 30s, display screen when button is pressed for the first time, the second time can enter the setting, enter the setting need password input.
♦When the manual setting is messy (dead), there is a reset key to reset to the default value.
♦When the controller is set in automatic and manual position, the display shows double points when pressing the double points button on the controller panel, but no alarm.
♦the controller is set to delay the time of switching, when the power supply is back to normal within the set value, the double power supply is not switched.
