7 Speed Controller Status input (input pulses
between B+ and GND to indicate error status
from Speed Controller)
121mV Normal (No faults). Voltage pulses
when fault is present.
Both
8 Baery “+“ lead 24.0v With vacuum motor running Both
9 Not used Both
10 Not used Both
11 Soluon Solenoid Valve winding 116mV When energized (Hold soluon but-
ton down)
Both
12 Vacuum Contactor winding 4.9V When energized, voltage inially
drops to 90mV then seles at 4.9v.
This is due to 100% “on” me at rst
to pull in the contactor, which is then
reduced to 80% to hold it in.
