We are starting to run production in our Hyundai Hit-15s with the 840c control.
Control button coolant on,off,auto won’t fire the pumps.
Nor will M codes M08-M09
We Can hold the contractor on the relay in for the pumps and they work. It looks like we have 2 pumps so I’m guessing we have high pressure coolant option?
Is there a R perimeter we can turn on or off in control. for the coolant? it looks like there is no signal from the control to the plc?
Any input would help thank you.
