9. Idle/Rated Switch Status displays the status of discrete input at terminal 17.
Closed indicates 24 Vdc is applied to the input selecting rated speed and
the maximum fuel limit is selected. Open indicates idle speed and the idle
fuel limit.
10. Raise Switch Status displays the status of discrete input at terminal 19.
Closed indicates 24 Vdc is applied to the input selecting raise speed.
11. Lower Switch Status displays the status of discrete input at terminal 18.
Closed indicates 24 Vdc is applied to the input selecting lower speed.
12. Alternate Dynamics Switch Status displays the status of discrete input at
terminal 20. Closed indicates 24 Vdc is applied to the input selecting the
Alternate Dynamics.
13. Remote Reference Switch Status displays the status of discrete input at
terminal 21. Closed enables the remote speed setting at terminals 14 and
15 and disables the Raise and Lower switches.
14. Isoch displays the status of the contacts at terminal 16. Open is droop,
closed is in isochronous.
15. Diagnostic indicates the status of the diagnostics switch.
16. Speed Switch A, terminal 3, indicates the on/off position of the switch.
17. Speed Switch B, terminal 4, indicates the on/off position of the switch.
18. Speed Switch C, terminal 5, indicates the on/off position of the switch.

Menu 6—Configuration Set Points
1.
Configuration Key is a code which must be entered before you can change
any of the set points on the configuration menu. This helps prevent
accidental modification of the set points. The code is factory set to “49”. Use
the “rabbit” or “turtle” keys to select the code. The code will be returned to
“0” when the menu is exited.
2.
Number of Gear Teeth is the number of teeth or holes in the gear or
flywheel that drives the speed-sensing device. If the gear is running at
camshaft speed (one-half engine speed) then you must enter one-half the
number of teeth on the gear. The control requires the number of teeth seen
by the MPU per engine revolution.
Best control performance will be obtained when sensing speed from
a gear rotating at full engine speed. Slower-speed gears (such as the
camshaft) provide a lower sampling rate which reduces control
response time.
