2 — INSTALLATION & WIRING: Throttle
Wiring for various throttles is described below. : In the text, throttles
are identified by their nominal range and not by their actual operating range.
If the throttle you are planning to use is not covered, contact the Curtis
office nearest you.
5kΩ–0 Throttle (“Type 1”)
e 5kΩ–0 throttle (called a “Type 1” throttle in the programming menu of
the handheld programmer) is a 2-wire resistive throttle that connects between
the 2-Wire Pot and Pot Low pins (Pins 16 and 14), as shown in Figure 4. It
doesn’t matter which wire goes on which pin. For Type 1 throttles, zero speed
corresponds to a nominal 5 kΩ measured between the two pins and full speed
corresponds to 0Ω. (: is wiring is also shown in the standard wiring
diagram, Figure 3.)

throttle (“Type 1”).
In addition to accommodating the basic 5kΩ–0 throttle, the Type 1 throttle
can also be used to implement a wigwag-style throttle. Using a 20kΩ pot wired
as shown in Figure 5, the pot wiper can be set such that the controller has 5 kΩ
between Pins 16 and 14 when the throttle is in the neutral position. e throttle
mechanism can then be designed such that rotating it either forward or back
decreases the resistance between Pins 16 and 14, which increases the controller
output. e throttle mechanism must provide signals to the controller’s forward
and reverse inputs independent of the throttle pot resistance. e controller
will not sense direction from the pot resistance with rottle Type 1. For true
