Introduction to the Model 3840 Electrician EVSE Tester
The Model 3840 Electrician EVSE Tester is a hand-held test unit that emulates an electric vehicle and is used to test the
operation and safety features of an installed Electric Vehicle Supply Equipment (EVSE). The tester complies with all of the
standards specified by the Society of Automotive Engineers (SAE), J1772 publications. This unit will test any
manufacturer/model EVSE that complies with the SAE J1772 standards.
The Model 3840 will measure signal levels, pulse widths and voltage levels generated by the EVSE under test and will indicate
to the operator (Electrician) the results of the measurement using high intensity LED’s.
The Model 3840 also allows the operator to test important safety features such as the ground fault protection circuit,
equipment grounding and reclosure functionality.
The unit is self-powered and requires no batteries. It is housed in a rugged, hand-held enclosure.

Product Description
The Model 3840 hand-held Electrician EVSE Tester was designed to provide a simple means of testing EVSE safety and operational
features. (Figure 2)
The control panel contains the following items:
(1) The range of currents that may be supplied to the electric vehicle from the EVSE under test, when powered from a 220VAC
source
(2) The range of currents that may be supplied to the electric vehicle from the EVSE under test when powered from a 110V AC
source
(3) Seven LED indicators to denote the maximum current that the EVSE under test is capable of supplying to the electric
vehicle. The value of this current is determined by the pulse width of the pilot signal received from the EVSE under test
(4) Charge on/off toggle switch necessary to activate the EVSE under test
(5) LED indicator to denote when the input voltage is between 95 and 125V AC
(6) LED indicator to denote when the input voltage is between 185 - 250V AC
(7) LED indicator to denote the presence and accuracy of the incoming pilot signal
(8) LED indicator to denote the presence and accuracy of the incoming proximity signal
(9) LED indicator to denote power is on/off
(10) Ground Fault Circuit Interrupter (GFCI) momentary switch, which applies a 20MA leakage path from line 1 to ground. This
will test the ground fault safety feature of the EVSE under test
The Enclosure:
(11) Rugged sealed high impact plastic enclosure

Operation
To test an EVSE, insert the J1772 connector of the EVSE under test into the J1772 inlet on the Model 3840 Tester (Figure 4).
Note: Your tester might have a cover over the SAE J1772 electric vehicle inlet. Press the latch on the right-hand side to
open the cover.
When the J1772 is inserted into the inlet, the Power LED lights, and the pilot voltage on Pin 4 (Figure 8) is reduced from +12VDC to
+9VDC with respect to Ground on Pin 3. This reduction in voltage signals the EVSE that the tester is connected. The EVSE in return
will convert the +9VDC signal to a +9VDC / -12VDC, square wave signal. The pulse width of this square wave will vary, from 10% to
95%, depending on the amount of current that the EVSE can supply to the Electric Vehicle.
In addition, a 150 ohm resistor to ground is connected to the Proximity input, Pin 5. This signals the tester that the J1772 connector
is attached and locked. The Model 3840 is now ready to test the EVSE.
When the Charge switch is toggled to the ON position (-), the Power LED will light up, the pilot signal will decrease to +6VDC peak.
This action will signal the EVSE to apply either 120VAC or 220VAC to Pins 1 and 2 on the Model 3840 Tester.
When AC power is applied to Pins 1 and 2, the microprocessor is activated and as a self-test, will sequentially light all of the status
LEDs.
The microprocessor will then measure the voltage on Pins 1 and 2, and depending on the amplitude, will light either the 110VAC or
220VAC status LED. When the AC voltage is between 185VAC and 250VAC, the 220V status LED is turned on steady. When the AC
voltage is between 95VAC and 125VAC, the 110V status LED is turned on steady. When the voltages are outside these ranges, the
voltage LEDs will flash (see Fault Conditions). The microprocessor will also measure the amplitude and pulse width of the pilot
signal. If the amplitude is within acceptable range, the maximum AC current available is determined by the microprocessor and
displayed by the current status LED indicators.
Based on the maximum current displayed, the rating of the service breaker should be 1.25 X the maximum current, i.e. 30A
displayed should be protected with a non-GFCI, 40A breaker. The maximum current displayed by the tester should never exceed the
rating displayed on the EVSE name plate. (The breaker rating should comply with all local and state electrical codes.) (Figure 5)
When the pilot signal is within the required J1772 specification, the pilot OK status LED is turned on steady. Should the pilot signal
not comply with the J1772 specification, the pilot LED will flash, indicating a problem (see Fault Conditions).
When the voltage, pilot and proximity status LEDs are on steady, the last two tests can be completed.

Press the release latch on the J1772 connector. (Do not remove the connector from inlet on Model 3840.) The proximity OK status
and Power LEDs should turn off when the release is pressed. (If not, see Fault Conditions). Push the J1772 connector back onto the
tester so that they lock back together.
Next, press the GFCI test momentary toggle switch to create a 20ma leakage current to ground. This should cause the EVSE under
test to drop AC power and indicate a ground fault condition. (If not, see Fault Conditions). All status LEDs on the Model 3840 will
turn off.
Most EVSE manufacturers will provide an automatic reclosure after a ground fault interception. Wait the specified time, and the
EVSE should once again supply voltage to the Model 3840 tester. (If not, see Fault Conditions).
The EVSE test is now completed.
