Please check the retaining ring. Your issue has to be either a mechanical blockage or an electrical connection.
The relay coil connects to the OpenEVSE controller on a 3 pin connector, one pin is open. This is a second relay channel. You can move the black wire from the side it is on to the open position.
When you plug into your car does the display change from "Ready" to "Connected" or "Charging"? Does the vehicle give any indication that the plug has be inserted?
@Antony - Programmers are now in stock, we just kitted up 100 pcs.
Any 6 pin Atmel AVR compatible programmer will work.
I have just now moved the black wire over to the open position.
OpenEVSE now goes ready - plug car in - connected - KLAK - a millisecond later ERROR NO GROUND.
Tried a few $ZS commands. Still ERROR NO GROUND. reset $ZS 255 255
Tried switching off Ground error detection - starts charging - at about 0.22A - even if set for 15A.
I don't see a retaining pin on the Struther Dunn, I don't see anything that would obstruct the Struther Dunn.
The issue is not likely the controller.
If the vehicle does not recognize the plug, the issue is the push button/latch. If the button does not click when you press and click again on release connected to the vehicle, charging will not begin.
You can test the button with a multimeter, if you measure resistance from the "Proximity" pin on the handle to the ground pin it should read 330 ohms and 480 ohms when pressed and released.
Type 2 still requires a resistor in the handle from the PP to ground. If the resistor is missing, the vehicle will not detect the plug.
|13 A||1.5 kilohms|
|20 A||680 ohms|
|32 A||200 ohms|
|63 A (3 phase) / 70 A (single phase)||100 ohms|
Testing procedure is the same, measure resistance from PP pin in handle to PE Earth.
What is the current capacity of the cable? A 32A cable should read 200 ohms. 10k does not correspond to any cable (see chart above).
