The BZ820-EV is the ideal first-line tool for checking EV chargers fitted with Type-2 connectors. The unit detects 28 wiring fault conditions and also checks the voltage supply level (L1). Correct polarity is indicated by three flashing green LEDs and a continuous audible tone. Fault conditions are clearly indicated by 3 red LEDs and a warning buzzer.
Socket polarity and earth wiring faults are identified by a combination of red LEDs. A look-up chart on the tester provides basic fault diagnosis. Further information is available in the product manual.
The BZ820-EV connects to an EVSE charging point using a Type 2 connector. The integral CP mode slider switch enables the simulation of various vehicle states: No vehicle connected (A), vehicle connected but not ready to charge (B), and vehicle connected and ready to charge (C). Mode C is used for testing. The additional “E” (error) setting simulates failure of the CP signal, which should cause the charger to inhibit charging. LEDs on the integral Type-2 plug show the status of the CP signal and if the voltage supply is present, single (L1) or three-phase (L1, L2 L3).
