AE/AR driver signals "S-321" for 6DS1730-8AA module
When accessing the 6DS1730-8AA module, the AE/AR driver (or TM_AE of
PCS 7/TM-EA) signals "S-321". The electrical components of the module seem
to be OK. What shall we do?
Please check whether the jumper X10/15-16 on the 6DS1730-8AA module
(marked "Reserve" in the Operating Instructions) has erroneously been installed
during commissioning (address setting). This jumper must never be installed.
It is open when the module is delivered from the factory.
