Curtis 1230 Manual, Rev. C
2 — INSTALLATION & WIRING: Controller
Fig. 4 Standard wiring configuration B: Curtis 1230-2X01 controller,
in applications with a 1312 tiller multiplexer (but without a proportional valve).
WIRING: Standard Configuration B (with multiplexer)
Figure 4 shows the typical wiring configuration for applications where a tiller
multiplexer is used. 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.
With configuration B, there is no control of the lift/lower speed; the lift
relay (at Pin 23) is a contactor that turns the pump motor on and off, and the
lower valve output (at Pin 24) opens and shuts the lowering valve.
