Foam Pump Cables
1. Connect the control cable (8 pin) from the control box terminal to the back
of the OIT control panel. Labels on the control box identify the terminal as
"OIT". See Page 13, Advantus Foam Pump Schematic.
2. All other cables for the manifold flow sensors.

tions.
3. Making round coils of extra OIT and flow sensor cables in the pump com
partment can act as an antenna. While the flow sensor and OIT cables
cannot be shortened, various lengths of cable are available to minimize
the "extra" cable in the truck. When routing cables, take care to avoid
routing them next to antenna cables, radio power lines and radio compon
ents. When there is extra cable, double the cable back on itself and secure
in a flat bundle with plastic wire ties instead of making a round coil.
Never attempt to cut or lengthen the molded cables. Cables can be
daisy-chained to obtain longer lengths.
Always disconnect the ground straps and control cables from the Operator
Interface Terminal (OIT) or other Advantus equipment before electric arc
welding at any point on the apparatus. Failure to do so could result in a
power surge through the unit that could cause irreparable damage to the
electronic components.

CAUTION
Foam Manifold Grounding
The manifolds must be grounded. If metal piping is used, sufficient grounding
may be present. However, Victaulic joints, plastic pipe, rubber hoses and
rubber mounted pumps interfere with proper grounding and an additional
ground wire may be required.
