PRODUCT SENTRY PRESSURE GOVERNOR BY AMS
6.6.9. Governor Gain (RPM per volt)
This menu item allows configuration of the RPM change per step. A larger number changes the RPM more with
each INCREASE or DECREASE click of the Twister control knob.
Note: Option only available with the Analog control type. This parameter is automatically set by the SENTRY when
the Auto Scale routine is run (see section 6.3.5 for more information). Enter the OEM 2 menu and select
“Governor Gain (RPM/V)” then press the INCREASE or DECREASE buttons to change to the desired value (250 to
1750 RPM/V in 25 RPM/V increments). Press the SAVE button to save the OEM 2 menu items and exit the menu.
6.6.10. Pressure Gain (pressure change per step)
This menu item allows configuration of the psi change per step. A larger number changes the PSI more with each
INCREASE or DECREASE click of the Twister control knob. Enter the OEM 2 menu and select “Pressure Gain
(PSI/kPa/Bar)” then press the INCREASE or DECREASE buttons to change to the desired value (1 to 5 PSI in 1
PSI increments). Press the SAVE button to save the OEM 2 menu items and exit the menu.
6.6.11. DITHER (Engine handshake)
This menu item allows enabling/disabling of engine handshake. Some engines require constant RPM modification
in order to maintain remote RPM control. When enabled, the SENTRY will vary the engine speed +/- 5 RPM
around the desired engine speed (CAN communication methods only). Enter the OEM 2 menu and select “Dither”
then press the INCREASE or DECREASE buttons to change to the desired value (YES or NO). Press the SAVE
button to save the OEM 2 menu items and exit the menu.
6.6.12. LAG (PSI/kPa/Bar)
This menu item allows configuration of the pressure lag which defines the maximum allowable difference that the
actual pressure is behind the commanded set-point before a “wait” (catch-up) state is introduced while operating in
pressure mode. Enter the OEM 2 menu and select “Lag (PSI/kPa/Bar” then press the INCREASE or DECREASE
buttons to change to the desired value (1 to 20 PSI in 1 PSI increments). Press the SAVE button to save the OEM
2 menu items and exit the menu.

This menu item allows configuration of the message configuration version transmitted in the Scania Body Control
Message 1. Enter the OEM 2 menu and select “BCM1 Ver” then press the INCREASE or DECREASE buttons to
change to the desired value (1 to 255). Press the SAVE button to save the OEM 2 menu items and exit the menu.
