Title: Where is the battery Post by: jay on January 20, 2014, 04:47:40 AM I have a number of progressive controllers older LED4 & LED5, they are no longer holding their programming for more than a day when the machines are off.
Which component is the battery ? that holds the info...... Title: Re: Where is the battery Post by: knagl on January 20, 2014, 08:43:12 AM I don't think I've seen one of those in person, but I'd take a close look at the green-wrapped circular thing -- could that be it?
Title: Re: Where is the battery Post by: stayouttadabunker on January 20, 2014, 01:35:44 PM I agree with Knagl...that green wrapped cell is a NEC 5.5V battery and it's positive (+) pole runs straight to
the 1st leg of the 4 diodes and 100 ohm resistor. It's negative (-) pole runs right to the blue capacitor next to it. Upon looking at it some more...it just looks like a cap? Now you've got me wondering where is the battery too? Here's a link to a similar .22 farad 5.5v green thing on Mouser. They call it a "Super Capacitor"...>>> http://www.mouser.com/ProductDetail/Kemet/FS0H224ZF/?qs=%2fha2pyFadugLzN1S7KquHrj1JFtHwCBEAT9DriN6mzG%2f%2fJx6hHuJew%3d%3d (http://www.mouser.com/ProductDetail/Kemet/FS0H224ZF/?qs=%2fha2pyFadugLzN1S7KquHrj1JFtHwCBEAT9DriN6mzG%2f%2fJx6hHuJew%3d%3d) |
