3. Overview
3.1. Product description
The Twister Electronic Throttle (p/n 119971) controls engine speed using a variable analog voltage connected to the
engine ECM for remote throttle applications. The Twister’s analog voltage range is 0.235 volts to 4.448 volts and the
minimum (idle) and maximum voltages can be configured between the standard range for specific engine
manufacturer requirements (refer to section 4.6).
The Twister utilizes L
READY LED is on the left-side of the control knob and the blue ACTIVE LED is on the right-side of the control knob.
The Twister has a control knob and an idle button for the operator to control engine speed. The control knob allows
manipulation of the engine speed within the configured (and engine allowable) RPM range. The idle button returns
the engine speed to the configured idle RPM.

To enter a password:
Press and hold the IDLE button until the ACTIVE LED blinks twice (two seconds). Continue holding the
IDLE button while entering the password.
A clockwise
rotation will turn the ACTIVE LED ON for a half- second and a counter-clockwise rotation
will turn the THROTTLE READY LED ON for a half-second. Wait for the LED indication to turn OFF before
rotating the knob again.
A rotation consists of at least one tactile click and a single rotation event is complete when the knob remains
stationary for at least half a second.
If an error is made while entering a password, release the IDLE button to clear and then re-attempt the
password from the beginning.
Invalid password entry
The THROTTLE READY and ACTIVE LEDs will quickly flash numerous times to indicate an attempted password is
invalid.

The Twister’s default configurations are:
Knob increase direction: Clockwise
Interlock polarity: Positive voltage
Maximum output signal voltage: 3.990 VDC
Idle output signal voltage: 0.235 VDC
Control knob initial dead band: 5 initial tactile clicks
4.6. Engine RPM range configuration
The Twister allows configuration of its idle output signal voltage and maximum output signal voltage which directly
affects the engine’s RPM range. The defaults are 0.235 volts at idle and 3.990 volts at maximum.
The idle offset voltage level affects the Twister’s maximum voltage level. When the idle offset voltage is configured to
its lowest level (0.235 volts) the maximum attainable voltage is 3.990 volts. When the idle offset voltage is configured
to its maximum level (2.392 volts) the maximum attainable voltage is 4.448 volts. The graph below (Figure 4) shows
the relationship between the configured idle offset voltage and its associated maximum voltage level.

Release the IDLE button.
The Twister sets its output signal voltage to the lowest point. Use the control knob to increase the output signal
voltage until the engine begins to increase its RPM. Use the control knob to find the base limit of control and then
press the IDLE button to save the output signal voltage as the idle voltage.
Engine manufacturers will program their ECMs for a curb idle. The Twister cannot force the engine ECM to attain a
lower RPM than the manufacturers curb idle.
4.6.2. Maximum RPM configuration
Enter the password:
Release the IDLE button.
The Twister sets its output signal voltage the configured idle voltage. Use the control knob to increase the output
signal voltage until the desired maximum RPM is attained. Press the IDLE button to save the output signal voltage
as the maximum voltage.
Engine manufacturers will program their ECMs for a maximum safe RPM limit. The Twister cannot force the engine
ECM to attain more RPM than the manufacturers limit.
4.7. Output Ramp Rate
The Twister (software version 1.2 and above) can be set for two different output ramp rates. The normal mode, which
is the default, increases/decreases the output signal voltage for every click of the control knob. The slow mode
increases/decreases the output signal voltage for every two clicks of the control knob, effectively creating a slower
response to the user input. In slow mode, the ramp time when returning to IDLE using the IDLE button is also twice as
long. The slow mode can be useful in matching the Twister to certain engines if the default ramp speeds are too fast.
Normal Mode (default):
Slow Mode:

Figure 5. Twister initialization.
5.2. Interlocking (enabling the Twister)
The Twister will not allow control of the engine speed until the interlock input (pin 3) has been activated. The interlock
input is activated when the proper voltage level is applied. The interlock voltage can be configured for system voltage
(default) or system ground (see section 0).
Figure 4 illustrates a typical interlocking scheme with the Twister’s interlock configured for system voltage. In this
example the OEM makes certain that the park brake and transmission are in the proper modes before allowing
system voltage to pass through to the Twister’s interlock input (pin 3).
Figure 6. Twister interlocking example.
The Twister’s green throttle ready LED will be ON when the proper voltage is applied to the interlock input. This
indicates that the Twister is ready for operator initiated control via the control knob. Refer to table Table 1 in section
3.2 for a description of the throttle ready LED status indication.

The OEM is responsible for creating a safe interlocking scheme to enable the Twister.

5.3. Controlling engine speed
The Twister allows the operator to control of the engine’s speed by rotating the control knob as long as the interlock is
active.
The blue ACTIVE LED will be ON once the control knob has been rotated in the increase RPM direction enough
clicks to overcome the configured initial deadband (default is 5 clicks).
Each tactile click of the control knob equals a 0.014 volt increase of the analog output signal voltage. With most
manufacturers this equals from 5 to 10 RPM per tactile click.

The blue ACTIVE LED indicator shows the status of the twister control (see Table 2 in section 3.3). The ACTIVE
LED will blink when the control knob is being rotated while the output signal voltage is already at the configured limit
(minimum or maximum voltage).
5.3.1. Control knob initial deadband
The Twister requires a number tactile clicks of the control knob in the increase direction before it will allow engine
control. This initial deadband keeps the Twister from inadvertently controlling engine speed caused by accidental
bumps, vibration, etc. The default number of tactile clicks is five (5) with each click occurring within a half-second
of the last. The blue ACTIVE LED activates and throttle control is allowed once the number of tactile clicks has
been established.

In the previous graphic (Figure 8) the first three tactile clicks are more than a half-second apart and are not counted
for the required number of deadband clicks. The next series of tactile clicks are a half-second (or less) apart and
the deadband counter counts each one up to the required number of clicks (5). The Twister then activates the blue
ACTIVE LED and allows active throttle control. Subsequent tactile clicks change the RPM of the engine and the
timing between clicks is not important. The initial deadband requirement will not be required again until the IDLE
button has been pressed and the engine RPM has been reduced to curb idle.
5.3.2. Returning the engine speed to idle
Press the idle button for a half-second to return the engine speed to idle. The twister will ramp the engine speed
from the current RPM down to the configured idle RPM at which time the blue ACTIVE LED will turn OFF to
indicate that idle has been reached.
