Hi all, I am having an issue with a Telemecanique counting module TSX CTY2A. This is a dual channel module. One of the encoders on the machine that was connected to channel 1 was damaged (cable broken). When I arrived at the machine, there was a solid red IO light on the TSX CTY2A module and also a red IO light on the TSX P57203 base PLC unit. On closer inspection the TSX CTY2A module has suffered some sort of surge or short as the board inside was burned and damaged. We installed a new encoder and a spare TSX CTY2A module. Once we powered up again, the red IO lights were still on both modules and I could immediately see some smoke coming from the newly installed module. The power was immediately switched off. The encoder cable has been belled out and checks out ok. I can only assume that there is an incorrect voltage somehow getting onto the counting side of the module. Any suggestions most welcome.
