IDLE SHUTDOWN TIMER AND PTO SHUTDOWN

The Idle Shutdown Timer will shutdown the engine if it remains idling for a specified period
of time. The options that can operate with Idle Shutdown Timer are Idle Shutdown Override,
Vehicle Power Shutdown or Shutdown on Power Take-off (PTO).
5.15.1 OPERATION — IDLE SHUTDOWN NON-PTO MODE
There are four modes of operation for Idle Shutdown:
□ Disabled – in this mode, idle shutdown will not occur.
□ Park Brake – in this mode, idle shutdown will be enabled only when the park brake is
applied, the accelerator pedal position is at zero and the engine is idling.
□ No Park Brake – this mode is the same as Park Brake Mode above, except there is no
requirement for the park brake to be applied.
□ Edge Triggered Accelerator Pedal – this mode has no requirement on the park brake or on
the engine being at idle. The operator may reset the Idle Shutdown procedure by moving
the accelerator pedal from below 40% to above 80%.
The idle shutdown period can range from 1 to 5000 seconds (approximately 83 minutes).
Certain conditions must be met for the entire time-out period for shutdown to occur. These
conditions include:
□ Coolant temperature above 50°F (–10°C)
□ Engine operation at idle
□ The parking brake ON, digital input switched to battery ground (optional)
□ Ignition ON
□ Vehicle Speed Less than 3 mph (5 kph)
Fueling is stopped after the specified idle time; the ignition circuit remains active after the engine
shuts down. The AWL will flash 20 seconds before the shutdown occurs. The RSL will flash 10
seconds before shutdown occurs. The AWL will continue flashing until the ignition is turned off
to indicate shutdown has occurred. The RSL will turn off. The ignition switch must be cycled to
OFF (wait 10 seconds) and back to ON before the engine will restart, if shutdown occurs.
A Park Brake Switch may be installed (see Figure 5-23).
