idle. If the signal is removed at any point the engine will remain at the
ACTUAL engine speed.
• Set / Resume mode. This mode provides the full Throttle Lock mode
functionality and uses all 5 available functions. This is the standard
Throttle Lock format.
The following sections describe the operation of each of the mode switches
and configurable settings.
11.3.1.1 ON/OFF switch
When this switch input is open then the Throttle Lock feature cannot be
engaged, and none of the other buttons will have any effect. When the switch
is turned off, any adjusted memorized speed will be lost.
11.3.1.2 Raise / Resume Button
When Throttle Lock has been switched ON, but not engaged, pressing the
Resume button will ramp the speed to the configured preset speed. Note: Any
overall ramp rates will only be applied to this ramp in speed (configured
separately from Throttle Lock feature).
If the Throttle Lock mode has already been engaged by the set button, then
the Raise / Resume button can be pressed or held down to increase the
engine speed. The ramp rates configured in the Throttle Lock feature will be
applied as well as any overall ramp rates (i.e. whichever is lowest).
After the mode has been disengaged using the disengage switch described
below, then pressing the Raise / Resume button will set the engine speed to
the last memorised speed.
11.3.1.3 Lower / Set Button
When the Throttle Lock mode is on but not engaged, the first time that the set
button is pressed it will save the current engine speed as the memorized
speed, and the engine will try to run at this speed.
Once that a Throttle Lock speed has been engaged, if the button is pressed
again, or if it is held down, then the engine speed will be lowered. The ramp
rates configured in the Throttle Lock feature will be applied as well as any
overall ramp rates (i.e. whichever is lowest).
11.3.1.4 Disengage Switch
If the disengage switch input is opened the engine speed will not follow the
memorised speed, but will return to the next highest engine speed demand
The disengage switch may be an operator panel switch, or may be a micro
switch on the brake, clutch, or other component of the application
11.3.1.5 Speed Toggle Switch
The Speed toggle switch enables the operator to select between two
configurable Set Speeds. This enables the operator to manually set two
Throttle Lock speeds and manually switch between them via a single switch.
