3. Features
This adapterKEW8602, simulating an EV (Electric Vehicle), can be
used for interfacing the EV charge stations, commonly named EVSE
(Electric Vehicle Service Equipment), and performs operation check
and electrical safety tests of EVSE.
In combination with a Multi-Function tester (not included), this adapter
also allows to carry out various electrical installation safety tests from
the EVSE socket.
KEW 8602 can test EVSE with TYPE 2 plug. When you test EVSE with
TYPE 1 plug, optional adapter (KEW 8603) is required.
Fig.3-1
Examples of connection: to an EVSE with cable or to an EVSE without cable
Note: This adapter is designed for testing the EVSE Mode 3 for AC
charging only.

Available functions:
●Pre-Test
verifies that there is no presence of dangerous voltage at the
grounded PE terminal.
●CP (Control Pilot) state check
varies Control Pilot signal (resistance between CP-PE) to simulate
various vehicle states (A/B/C/D) for EVSE operation check.
●PP (Proximity Pilot) state check
varies Proximity Pilot signal (resistance between PP-PE) to imitate
various charge cables with different ratings for EVSE operation
check.
●CP (Control Pilot) signal error simulation
simulates the state that CP signal short-circuited to PE and confirm
that EVSE stops AC power flow.
●PE (Earth fault) Error simulation
simulates an interruption of PE conductor and confirm that EVSE
stops AC power flow.
● Phase voltage check LED
indicates the phase voltage of charge plug of EVSE.
●CP (Control Pilot) signal output terminal
is connected to an oscilloscope to analyze Control Pilot signal.
●Measuring terminal and mains socket
are available for various installation tests.
(Mains socket is dedicated to test EVSE connected to single phase
supply.)

5.Test procedures
5.1Connection
Connect EVSE connection plug of KEW 8602 to an EVSE to be tested
(with or without cable as the following examples).
5.2 Pre-Test
After connected with the EVSE under test, touch the touch pad (4)
with a bear finger. Normally the PE conductor is connected to ground
and has no voltage to ground. If a dangerous high voltage is present
at the PE conductor, Pre-Test warning LED (4) lights up. In such a
case, stop further testing immediately and check the wiring
connections. (e.g.: The PE conductor isn't connected to ground or is
connected to phase by mistake.)
* Pre-Test must be conducted prior to other tests.
* Touch the touch pad with a bare finger. Do not wear insulated
gloves.
Ensure a proper connection to the ground (though your shoes),
otherwise, warning indication with (4) Pre-Test warning LED may not
be reliable.

5.3CP (Control Pilot) state check
Switch the CP state selector (6) to simulate various vehicle state (A/
B/C/D) and check the behavior of EVSE.
Fig.5-3
1) Set the CP state selector (6) to position “A” (car not connected)
and connect KEW 8602 to EVSE.
2) Turn and set the CP state selector (6) to position “B” (car
connected).
(The EVSE under test may require payment information.)
3) Turn and set the CP state selector (6) to position “C” (car
charging) or “D” (car charging with ventilation).
Confirm that EVSE is ready for charging.
The phase indicators are LEDs, one LED for each phase. When
phase voltages are present at the EVSE, the LED indicators will
light up.
* LED L1 lights up when testing a single-phase circuit and LEDs
L1/ L2/ L3 light up for a three-phase circuit.
* In the case where the circuit under test doesn’t have a neutral
wire, no LED light up.
* If the EVSE isn’t ready for charging, turn the CP selector (6) to
“A” and wait for a few minutes. Then turn the CP selector (6) to
position C or D.
