Mains-powered units with back-up battery
If AMFLO SONIC UFA-280 is mains-powered, a battery can be inserted as back-up power supply to ensure continuous operation in the
®
event of power failure. Depending on duration and numbers of mains power failures, battery has a lifetime of minimum 6 years (one battery).
(Average: one mains power failure per day (duration 1 hour) for min. 6 years).
Check that mains power supply symbol appears in display when installation is complete.This symbol indicates that installation is correct.
If mains power supply connection is not established correctly, flowmeter will operate on battery power only. Battery life will be significantly
shorter if batteries are used continuously as opposed to only occasionally in a back-up function.
