Mount the Twister™ (p/n 119971) on the operator’s panel with four
#6 screws and nuts. The dimensions in the detail below are in
inches [millimeters].

WIRING

The Twister has a single six (6) pin Deutsch connector. The mating
connector is a DT06-6S.

The Twister has two (2) LEDs located on its front panel on either side
of the control knob.

Throttle Ready LED:

The green THROTTLE READY LED is ON when the Twister’s
interlock (pin 3) is active. This indicates the Twister is ready for
operator initiated control via the control knob.

The THROTTLE READY LED flashes when the Twister’s

analog
signal is not within the valid range. No throttle control is permitted
when the THROTTLE READY LED is flashing.

Active LED:

The blue ACTIVE LED is ON when the Twister’s knob has been
turned in the increase RPM direction. This LED indicates the Twister
is actively controlling the engine with its analog output voltage.

The ACTIVE LED flashes when the operator is rotating the control
knob while the Twister’s output voltage is at the configured minimum
or maximum.

ENTERING PASSWORDS

IDLE BUTTON OPERATION

The Twister’s IDLE button is used to set the engine RPM back to
idle (and enter passwords for configuration).

Press and hold the IDLE button for a half second and the engine
ramps down to the configured idle RPM. The ACTIVE LED remains
ON while the Twister ramps the engine to idle and then it turns OFF.

CONTROL KNOB OPERATION

The Twister’s control knob is used to control engine RPM (and enter
passwords for configuration).

The “increase RPM" direction of the control knob can be configured
for clockwise or counter-clockwise rotation (clockwise is default).

The control knob utilizes 5 ¼ turns for full span of output voltage
(from idle to maximum).

The Twister utilizes passwords to modify its operational parameters.
All operational parameters are stored in memory and will not be lost
when power is disconnected.

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.

 Each clockwise

half- second and each counter-clockwise

rotation will turn the ACTIVE LED ON for a

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.

If an error is made while entering a password, release the IDLE
button to clear and then re-attempt the password from the beginning.

ANALOG OUTPUT VOLTAGE CONFIGURATION

KNOB ROTATION CONFIGURATION

Engine manufacturers have different requirements for the analog
voltage input into their Engine Control Modules. Some
manufactures may require and idle voltage of 0.7 VDC and a
maximum voltage of 4.0 VDC and others may require an idle voltage
of 1.0 VDC and a maximum voltage of 3.7 VDC.

The Twister allows configuration of its minimum and maximum
analog output voltage for meeting the analog voltage requirement of
Engine Control Module. The Twister’s default analog output voltage
range is 0.25 VDC to 4.2 VDC.

Idle voltage configuration:

Enter the password -

Release the IDLE button.

Make certain the interlock input (pin 3) is active, the engine is
running, and the ECM’s remote throttle enable is active.

Rotate the Twister’s knob in the INCREASE RPM direction
(clockwise is default) until the engine’s RPM increases.

Rotate the Twister’s knob in the DECREASE RPM direction
(counter-clockwise is default) until the engine’s RPM has just
reached its natural idle RPM.

Press the IDLE button for one (1) second to save the idle voltage.

Maximum voltage configuration:

Enter the password -

Release the IDLE button.

Make certain the interlock input (pin 3) is active, the engine is
running, and the ECM’s remote throttle enable is active.

Rotate the Twister’s knob in the INCREASE RPM direction
(clockwise is default) until the desired maximum engine RPM is
reached.

Press the IDLE button for one (1) second to save the maximum
voltage.

The analog output voltage configurations are saved in memory and
will not be lost due to power interruption or by unplugging the
Twister’s connector.

The Twister allows the knob rotation direction for increase RPM to be
configured. The default is clockwise rotation yields an increase in
engine RPM. But this may be changed to counter-clockwise rotation
yields an increase in engine RPM by entering a password.

Clockwise rotation equals increase engine RPM (default):

Counter-clockwise rotation equals increase engine RPM:

INTERLOCKING

The interlock input (pin 3) must be active before the Twister will
allow control of the engine’s RPM.

It is the OEM’s responsibility to create a safe interlocking scheme to
activate the Twister’s interlock input.

The Twister’s green THROTTLE READY LED will ON when the
interlock input is active. The Twister is now ready for operator
initiated control.

The Twister
activation polarity (positive voltage or ground).

Positive polarity interlock configuration password (default):

Ground polarity interlock configuration password:

allows configuration of the interlock input’s (pin 3)
