INSTALLATION
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.
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).
LED OPERATION
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
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 rotation will turn the ACTIVE LED ON for a
half- second and each 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.
If an error is made while entering a password, release the IDLE
button to clear and then re-attempt the password from the beginning.
