7.2 EZ 1000 with AMS 6500
Use an additional diode when connecting an EZ 1000 converter through safety barriers to
cards for eddy current sensors of the AMS 6500 system.
The nominal voltage of the safety barriers with U
0
= -28 V is slightly lower than the nominal
supply voltage of the AMS 6500 cards for eddy current measuring chains. To reduce
unintentional and disturbing effects, it is necessary to integrate a diode module into the
converter supply circuit. Install the diode module between the safety barrier for the supply
circuit and the AMS 6500 card. Diode module and safety barrier for the supply circuit are
delivered together in a package (order code: MPT9001/00-280/085/101)
