HI All,
I am experiencing one problem for few months which i would like to share with you experts. My SLC and Micro Logix Controller especially Micro Logix are experiecing this problem. The Power Supply of the Controller is powered up by an external 24V DC Battery Source which is charged by compressor alternator so that the battery doesnt get drained, but usually we found out during Preventive Maintenance of Compressor when the compressor is down and the alternator also. When we try to start the PLC after 7 or 8 Hours later its program is washed out from the controller which then needed to be downloaded again. The interesing part is this that i have tried several of time to disconnect power of controller by myself during compressor running then after power up it shows the program but i think when the battery get drain gradually it program is washed out from it. Does this assumption of mine is correct and what can we do to avoid it.
Regrads,
Sam Khan
