WIRING: Standard Configuration C (with multiplexer & PV)
Figure 5 shows the typical wiring configuration for applications where a pro-
portional valve is used with the tiller multiplexer. Most 1230 models designed
for use with a multiplexer include an internal main contactor (see specifications
in Table C-1); for the 1230-2301 and -2401 models, which do not, the main
contactor should be wired as shown in Figure 3. If there is a load hold valve,
it needs to be controlled externally.
The proportional valve in configuration C is controlled by the hydraulic
throttle in the multiplexer, providing variable speed lift/lower operation.
