PTO Mode Interlocks
PTO interlocks provide an extra level of component protection when operating the
engine in PTO Mode. The engine enters PTO Mode when the engine receives a
signal via hardwired engagement feedback or a signal from a body controller via
BCAN. If an interlock condition exists, the engine will not enter PTO Mode until the
interlock condition is eliminated. An existing interlock condition does NOT prevent
the PTO from mechanically engaging or cause the PTO device to disengage and will
only prevent the engine from entering PTO Mode. When in PTO Mode, if one of the
interlock conditions occur, the engine control unit (ECU) reverts back to normal
driving mode and all controls, logic, and limits related to PTO Mode will become
inactive. This includes limits related to minimum engine speed, maximum engine
speed, maximum vehicle speed, and maximum engine torque. Other PTO Mode
features, such as disabling the idle shutdown timer and logging PTO Mode hours
and fuel usage will also become inactive.
The following list describes the available PTO Mode interlocks and the conditions
that will prevent the engine from entering PTO Mode, or cause the engine to exit
PTO Mode:
Disable PTO Mode w/Clutch Depressed (
– When this interlock is
enabled, operating the clutch pedal will cause the engine to exit PTO Mode.
o
Disabled for mobile applications
Disable PTO Mode w/ Brake Depressed (
– When this interlock is
enabled, operating the service brake pedal will cause the engine to exit PTO
Mode.
o
Required for Mobile Cab Station Accelerator and Switches
PTO Mode Vehicle Speed Limit (N080)
is greater
than 3 MPH
o
May be disabled for Mobile Cab Station Accelerator Only and all
Remote station configurations
Require Parking Brake for PTO Mode (
– When this interlock is
enabled, disengaging the parking brake will cause the engine to exit PTO
Mode, or prevent the engine from entering PTO Mode.
o
This interlock is automatically configured based on the selected
configuration and is
required
for all stationary PTO applications.
Neutral Required for PTO Mode (
– When this interlock is enabled,
the transmission must be in neutral to allow the engine to enter PTO Mode.
With this interlock enabled, shifting the transmission out of the neutral
position will cause the engine to exit PTO Mode.
o
This interlock is disabled for mobile applications.
PTO Mode Vehicle Speed Limit (
– While in PTO Mode, the vehicle
will not accelerate past the
Maximum Vehicle Speed During PTO Operation
