Problems with the ready led of FP-PG-522

[Visintin]

After 6 months of good functioning, now I often have the READY LED on my FP-PG-522 goes off. My configuration is: 1: FP-1601, 2: FP-AI-100; 3: FP-AI-100; 4: FP-DI-301; 5: FP-PG-522; 6: FP-PG-522; 7: FP-QUAD-510.

In detail I have several times the READY LED off on the board in FP-PG-522 on position 5 and only sometimes the READY LED off on the board FP-PG-522 in position 6.

The installation of the modules is in vertical direction. Could be a problem?

Please, could you suggest any troubleshooting. For the moment I solved my problem by moving a little the Terminal bases without swapping anything.

Thanks

Sometimes such a beavior depends on small adjustements in DIN rails, due to seasonal temperature changes. The only workaround is to release slightly the screws of the Din rail in order to let it move with less tight bonds.
hope it works

Massimo,

Since the problem went away when you shifted the terminal bases, it is likely that the bases had shifted such that one or more pins was no longer making contact. If you do not already have DIN rail locks in place, I would recommend installing them.
