2.8 - MONITORING OF WELDED RELAY CONTACTS FAILURE

According to IEC 61851-1 and EV/ZE Ready requirements, EVC04 EV Charging Station has welded
contactor sensing function, and welded contactor information is provided as a contactor welded
output signal from the control board. To detect welded contact failure for the relays, CN33 connector
output terminals must be used.
In case of a welded contact for the relays CN33 connector output will be 230V AC. The output
which has 230V AC should be connected to a shunt trip for RCCB triggering as shown in figure-22.
The cabling should be done as shown in figure-23.
Connector (CN33) terminals must be connected to a Shunt trip module. Shunt Trip module is
mechanically coupled to RCCB (or MCB) at the fuse box of the charging station.
The circuitry block diagram that must be used at the fuse box of the charging station is shown below.
