Switching a contactor from a new Sub-meter

[Sparksfly]

Hello

Does anyone have experience of switching a E7 contactor from a meter?

I am swapping out a RPTS Sangamo used for E7 Heating (via Moeller 50A contactor), it swaps high/low rate on an old analogue sub-meter.

Customer has given me a dual rate Iskra ME162 -D3A42-G22-M3K0 meter which has 4 main terminals and small auxiliary terminals. Tried testing while rate 2 was on but could not switch the contactor on via the Aux outputs. Maybe this meter just indicates dual rate !

I can switch the contactor manually
I have tried Iskra via email and phone numbers that seem invalid, supplier scratching head, so struggling with technical help.

Any pointers on this subject would be much appreciated, thanks in advance.

The meter says NC above the middle terminal. NC would imply it is normally closed. I guess these are clean contacts, it does look like there are 3 separate connections, have you tried for continuity between any of them?

Also how does the meter "know" when to switch? you would need to over ride it to test the contactor.

You might need the software https://www.iskra.eu/en/Iskra-Software/MiQen-Settings-Studio/
and optical interface https://iskraemeco.com/products/sonda-optical-probe/ to set the time and operating parameters

Where do the brown black and blue go to?

I put these in to test individual outputs from the meter to contactor, as space restrictions were so tight swapping wires out ....unfortunately the rate 2 timed out after 07:30...so I left them in for next time.

I tried to test continuity between the terminals on the right but I cant remember if between NC Terminals and those three. Also tested between neutral and live to the smaller terminals. Nothing seemed to show anything had switched or was linked to anything else while on rate 2.

Thank you for these will look into it. I did have the tech document but the auxiliary outputs mentioned pulsed input/outputs.... was hoping for a switched/linked output in the meter to neutral.
