Curtis Model 1351 – December 2018
THE SYSTEM CONTROLLER’S WIRING DIAGRAM (EXAMPLE)
The 1351’s Inputs and Outputs (I/O) can easily conform to a wide range of applications. Use this chapter
and Chapter 3’s parameters information for insight into using and setting up each type of I/O. Figure
4 is the example-wiring diagram using the 1351 as an ICE driven hydraulic systems controller. In this
example, the Lift/Lower and Steer Angle potentiometers connections are 3-wire potentiometer inputs,
while the control of the main contactor is by another device. Figure 4’s connections are representative
of just some of the possible 1351 System Controller wiring configurations.
Note: In cases where an application’s wiring and I/O usage deviates from the wiring shown in Figure 4,
it is up to the OEM to evaluate the overall system safety. Always ensure a configuration is thoroughly
tested and verified for the application.
