Switching between indication modes of “Total elapsed engine time “, “Instant fuel
flow”, “Remaining fuel volume”, “Time of running with remaining fuel”, “On-board voltage”,
“Engine operation time for selected period”, and switching between messages on faults
are effected with “Mode” button of the control panel 18 (figure 2.1.1). Description of mode
operation algorithms„Testing workability of speed sensors”, “Testing workability of fre-
quency fuel volume sensor (FFVS)”, “testing workability and connection of CAN-bus to the
Integrated Indicator” is given below.
1. Total elapsed engine time, h
The counter accumulates information on the total
elapsed engine time with uploading a message “engine
speed” from the engine control unit and stores it when
the power supply is off. The range of engine time indica-
tions is from 0 to 99999 hours.
2. Instant fuel flow, l/h
In this mode a current value of the instant fuel flow with a resolution
of 0,1 l/h is displayed.
3. On-board voltage, V
In this mode a current value of on-board voltage with an accuracy of
0,1 V is displayed in a digital form.
4. Remaining fuel volume in the tank, l
In this mode a current fuel volume remaining in the tank is dis-
played in liters.
This mode is available only when the tractor is stopped (i.e. when
there are no signals from the speed sensors).
Note: Tractor should be stopped on horizontal surface in order to increase displaying accu-
racy of fuel amount in tank.
5. Time of running on remaining fuel, h
In this mode assessed engine time, calculated for current values of
the instant fuel flow and remaining fuel volume is displayed, (indica-
tion increment is 0.1 hour).
6. Engine operation time for selected period
In this mode engine operation time with 1/10-of-an-hour accuracy for a
selected period of operation is displayed. If required it is possible to zero
the counter value by way of pressing the “Mode” button and keeping it
pressed for at least 2 sec.
