Figure 5-21: Wiring Diagram: 9852XTW1, 9852XTW2, 9853XTW1, 9853XTW2 Dispensers
Diagrams shown are for Q Model pumps. If your pump is an A model, DC junction box will be separate.
Notes:
1.The power resistor assembly is 8.2K OHM, 10W (P/N C05818) for 115/230 VAC domestic units and 30K OHM, 10W (P/N
C06683) for 230 VAC international units. Two assemblies required for twins.
2. Before applying power, the TopKAT Pump Control PCB jumpers must be set for electronic pulser as shown in
Block ID" on page
34. Failure to properly set the jumpers will damage the TopKAT.
3. Wire colors shown reflect current production since June 1998. If your 9800 is older than June 1998, your wire colors may
vary.
4. When multiple dispensers are used to control a common submersible starter relay or pump, and the 9800 is controlled
(authorized) through the Control/Subm Feed line (as in the case of some fuel management systems), it is important that the
lines from the 9800 to the submersible equipment be isolated from each other. This can be accomplished by running the
submersible control lines through a secondary set of relay contacts in the fuel management system. If a secondary set of
contacts is not available, external control relays must be used between the 9800 and the submersible starter relay or pump.
Another option is to provide a separate submersible starter relay for each hose outlet. In no case can the submersible drive
lines from the 9800 be tied together.
