BB-4 Wiring
Standard WATERAX wiring configuration:
All vehicle BB-4 pumps are wired from the factory to work with an XCP control panel. To revert to the
original engine controls, refer to the next section for instructions.
XCP vs. Engine Controls:
A
WATERAX
XCP control panel should not be operated simultaneously with the original engine controls;
undesired behaviors may occur. It is recommended to remove the key switch from the engine and store it
in a safe location if equipped with an XCP.
Warning LED Indicators:
The BB-4-21H (GX630) comes equipped with a Honda Engine Controls Box (ECB) which has a Low Oil
LED indicator. When operating the pump with an XCP control panel, the Honda ECB Low Oil LED will turn
on when the stop toggle switch or the Low Pressure Protection turns off the engine. The Honda ECB Low
Oil LED indicator MUST be ignored. To turn off the ECB Low Oil LED, cut the power to the engine.
Only
the warning indications on the XCP panel are to be considered when operating the pump with an
XCP panel.
