Hours counters
The controller supports many different hours counters for various functions. Some counters run
on all units and some only run on the Gen4 configured as the vehicle master.
Hours counters are preserved with a minimum resolution of 15 seconds when the system is
powered down.
Local hours counters
Local hours counters which run on all units are:
Controller key hours: increments while the keyswitch is in the ON position (5200
Controller pulsing hours: increments when the controller is powering its connected motor
(4601
).

Vehicle hours counters
Vehicle hours counters which run only on the Gen4 configured as the vehicle master are:
Vehicle key hours: increments as controller key hours (2781
Vehicle traction hours: increments when the vehicle is driving or braking (2782
Vehicle pump hours: increments when the pump motor is running (2783
Vehicle power steer hours: increments when the power steer motor is running (2784
Vehicle work hours: increments when the traction, pump or power steer motors are running
(2785
).

Since these hours are specific to the vehicle, they are writeable so that they can be reset to
known good values if the master controller is replaced.
Logging
The controller can log events in the system (along with additional event-related information) and
minimum and maximum levels of important parameters. You need different levels of access to
clear the contents of the logs.
Logs are normally reset individually. However, to reset all logs at once write to 4000
FIFO event logs
Events are recorded by these two separate FIFOs (first in, first out logs), which operate
identically:
System: this FIFO is 20 elements deep and is used for events such as software upgrades,
user logins and some hardware upgrades (4100
Faults: this FIFO is 40 elements deep and is used for fault logging (4110
