c) Controls. This menu sets which input source is used for the listed items. Based upon the
application’s wiring, assign each of the menu’s parameters to a specic switch. e rottle,
Brake, and Steer sources are analog inputs. Set the input type (i.e., either a switch or an “analog”
voltage) for the Li, Li Limit Switch, and the Lower Input that matches the application. Refer
to Figure 6 as a guide.

Brake Source = 0 (not used in Fig. 6) *

Step 9. Inputs
Congure the Inputs menu. Analog1 default setting is as a 3-wire potentiometer. e other analog inputs
are available for general usage, although as illustrated in Figure 6, Analog 2 is the motor temperature
sensor, and Analog 3 and 4 are the encoder signal inputs. As such, Analog 2, 3, and 4 do not need to be
congured in this menu because their assignments are the default when the motor temperature sensor
is enabled and the motor Position Sensor Type is assigned.
If a voltage-based throttle is used, set it now. If a potentiometer-based throttle is used, set it now as
either a 3-wire or 2-wire. If a VCL throttle is employed, the Analog 1 Type parameter is ignored as a
throttle, freeing this input to function as assigned. For example, the input can be assigned as a brake
input, which would necessitate the Brake Source in Step 10 be set = 1 (for Analog 1). Figure 6 shows
Analog 18 as a 2-wire potentiometer the brake throttle. Yet, it could as easily be a voltage-type input,
or via the CANbus and processed in VCL, as shown in Figure 7, the CANbus Tiller-Head example.
See Programmer » Controller Setup » Inputs.
Traction Throttle Setup
e controller accepts Class III tiller handles with ipper and/or twist-grip throttles whether with
forward and reverse switches or those of the wigwag type (symmetrical throttle response in both the
forward and reverse directions, yet without directional switches). From Curtis, the ET-126 throttle
assembly oers a symmetrical 0–5 V Hall-eect throttle featuring a wigwag type throttle-return-to-
neutral, and solid-state forward and reverse switches. Alternatively, when implementing a traditional
foot throttle, Curtis oers both 3-wire potentiometer and Hall-eect voltage throttles—as complete
pedal-assemblies, which easily integrate into vehicles.
The throttle setup depends upon the type used. Possible types include voltage, 3-wire or 2-wire
potentiometers, and those received over the CANbus and processed using VCL. e controller also accepts
PWM (signal output) position sensor type throttles. See each of the representative setup examples below.
In all cases, the throttle command is as a percentage (%) and not voltage. e voltage at an input will
change due to the dynamic checks at the input which verify the integrity of the input signal. is is new
to the FOS-series controllers and diers from the E/SE-series controllers (that display a “steady” voltage).
All throttle setups use the Curtis Integrated Toolkit
TM
to assign/set the throttle parameters. Figure
24 illustrates the Programmer’s throttle-related parameters.
Before setting up the throttle parameters, turn the Interlock O. is will prevent accidental motor
operation. e Interlock was “assigned” to a switch (digital) input, the example being Switch 5 (pin 9)
as illustrated in Figure 6 (see Step 8b). Read the Interlock Input Source (value displayed) and then the
indicated switch for its On/O status in the Programmer » Controller Setup » IO Assignments » Switch
Assignment menu and then the Switch Status menu (or use Programmer » System Monitor » Inputs »
Switch Status menu). If the Programmer indicates the interlock is On, review how the Interlock Type
parameter set and turn the interlock O.
