Testing with the EVX
6.7 Running a loop impedance test:
To perform any Loop impedance measurements on the EV charger the charger must be in
State C2. The EVX will automatically set the charger to this state when the MFT-X1 and the EVX
are connected and switched on.
NOTE : The hands-free automatic Loop test does not operate with the EVX connected.
1. Ensure the EVX is connected to the MFT-X1.
2. Connect the test lead from the EVX to the EV charger if not already connected.
3. Select the Loop test function on the left rotary knob of the MFT-X1.
4. The EV Charger should switch to State C2 and live voltage should be indicated in the
voltage widget on the MFT display as below:
Loop mode widget shows live volts
NOTE : The Interlock should also engage on the EV charger to prevent the EVX connector from
being disconnected from the EV charger.
5. Press Hot key 1 to select Z
6. Press Hot key 5 to select the circuit connection you wish to test, either:
L1-PE, L1-N, L2-PE, L2-N, L3-PE, L3-N, L1-L2, L2-L3, L1-L3.
7. Press Hot key 4 to select either 3 wire or 2 wire depending on the type of test being run.
e.g. For a L-PE test you can select 3 wire. For a L-N or L-L test select 2 wire.
8. For testing L-PE circuits select RDC EV or RCD on Hot Key 2 depending on the protection
device in the EV charger. If testing L-N or L-L circuits select NO RCD on Hot key 2
9. Select L-PE on Hot key 5
10. Select the circuit path to be tested using Hot key 4 as below:
11. For 7 kW or lower EV chargers select L1-PE
12. For >7 kW chargers select L1-PE, L2-PE or L3-PE for earth loop impedance testing, or
L-N, L1-L2, L2-L3 or L1-L3 for multi-phase testing.
13. Touch the TEST button and verify no PE or Reverse L-N error is generated. If a PE error is
displayed the earthing of the EV charger should be checked for bonding errors. If an L-N
swapped error is displayed verify the live conductors are not swapped in the supply to the
charger.
NOTE : Both of these warnings will inhibit the MFT-X1 from performing a loop measurement.
NOTE : The L-N swapped warning and inhibit can be disabled in SETTINGS for the MFT-X1.
