If "PTO Throttle Override Enable" is enabled, the throttle pedal can override the PTO Engine
speed up to the Maximum Engine Speed for Throttle Override. If the throttle pedal or remote
throttle engine speed is less than current PTO engine speed, the engine will not respond to throttle
requests less than the current PTO engine set speed. The previous PTO set speed will become
active again, if it is greater than the engine speed equivalent to the throttle pedal percentage.
NOTE:
If remote PTO is active and then disabled due to one or more disabling conditions, PTO
mode will automatically reactivate when the disabling condition is removed.
There are three options using preprogrammed set speeds:
□ Pulsed Input using pin 2/9
□ Gray Coded using pins 2/9, 1/11, 2/11
□ Binary Coded using pins 2/9, 1/11, 2/11
Pulsed Input Using Pin 2/9
Between one and three preset speeds can be set via "No of Speeds via Remote PTO". The first
speed is selected by toggling 2/9 ON. The second speed is selected by toggling 2.9 OFF and ON
within two seconds. The third speed is selected by toggling 2.9 OFF and ON within two seconds.
Remote PTO speed is disabled for any of the following:
□ Turning the Remote PTO switch off for more than two seconds
□ Vehicle speed is greater than Max Vehicle Speed in PTO (programmable – default 10 km/h)
□ VSS fault
□ Clutch Released Pedal or Service Brake Pedal are pressed (if configured)
□ Park Brake is OFF (if configured)
□ Park Brake or Service Brake is applied (PTO Dropout Serv Brk Prk Brk)
□ Cruise Switch fault
□ Clutch Pedal is pressed (PTO dropout on clutch enabled)
□ Optimized Idle is active
NOTE:
If remote PTO is active and then disabled due to one or more disabling conditions,
Remote PTO mode will automatically reactivate when the disabling condition is removed.
