Engine Operation
Idle
After the operator starts the engine:
the Controller will set the TSC1 request to TSC Min
throttle keys will be locked out until the operate digital input is asserted
Idle mode is entered in one of two ways:
manually – the operator asserts the Idle digital input
automatically – the engine generates a red-lamp fault
General Operating Mode
After the operator switches the Operate digital input:
the Controller will immediately set the TSC1 request to the High Pressure On Setting
no ramping
after the engine reaches the High Pressure On Setting (within ± 50 RPM tolerance), the
Controller will:
energize the clutch output
begin targeting (speed or pressure)
enable the throttle keys
When the operator switches to the Idle digital input the Controller will:
disable the throttle keys
de-energize the clutch output
drop the engine speed back to TSC minimum (no ramping)
RPM Operating Mode
The RPM Operating Mode begins after the engine has reached the High Pressure On Setting.
The Controller will:
set the TSC1 requested speed to the target speed
it is the responsibility of the engine electronic governor to maintain the requested speed
increase the target speed by 50 RPM in response to each Throttle Up button press
maximum of 2150 RPM
TSC1 requested speed will immediately follow this change
decrease the target speed by 50 RPM in response to each Throttle Down button press
minimum of 1200 RPM
TSC1 requested speed will immediately follow this change
