ac 800m controller program washes away every time it restarts.
I am using ac 851controller. I downloaded a program into a fresh controller after upgrading firmware and setting ip address and it gets into run mode. But once i switch off the supply and restarts the controller the program doesn't exists as if the controller is empty. What could be the reason?

Check your internal battery (3.6V) or SB821 (3.6V).

Hi
There is screw on the top right front of the Controller open this and then slide the top cover then you will find there is small battery inside which is normally with these spec
Built-in back-up battery
Type: Lithium, 3.6 V, 0.95 Ah, size 1/2 AA (it's easyily avilable in the local markets)
just take this one out and insert new battery and close the cover. when your battery will be healthy then "B" lite with stop blinking and it will be stable like run and other lights. Your controllr suppose to be on UPS power (highly recommeneded)

Better yet, take your internal battery and throw it away. Replace it with an external battery ( SB821 or SB822 ). The internal batteries are not very reliable, mainly because they do not last very long and get forgotton about.
