Smart Tachograph EFAS-4.10/4.11
many calibration/programming devices do not allow for entries after the decimal point, so that the values require multiplication
by a factor of 1000.
Typical settings are:
0.001 pulses/rev, 5.796 pulses/rev, 6.000 pulses/rev, 8.000 pulses/rev, 8.138 pulses/rev, 10.000 pulses/rev , 12.217 pulses/rev
Warning An incorrect parameter setting can lead to malfunction or damage to the transmission and other serious dis-
turbances of the driving and braking functions. Please make sure that the value is set correctly. If in doubt,
contact the vehicle manufacturer or take the value used for a tachograph previously installed in the vehicle.
8.3.10 Selection of engine-speed data source (RCI=0xFD3A)
In the “additional data recording” the engine speed of the vehicle is recorded by the tachograph. The engine speed signal is
either read from the CAN bus or it is taken from a corresponding pulse signal at the connector C3.
The engine speed source is selected with the parameter RDI=0xFD3A. The parameter RDI=0xFD32 (n-factor, see section8.3.11)
species the engine-speed factor to be applied when using the pulse input to calculate engine speed. If engine speed is read
over the CAN bus, no further conversion is necessary and the n-factor does not need to be set.
8.3.11 Engine speed factor (n-factor) (RDI=0xFD32)
This parameter contains the constant for the calculating engine speed from the pulse input at pin C3. The value of the constant
represents the number of pulses per 1000 revolutions of the drive shaft. The operating software does not evaluate this param-
eter if the engine speed is received via the CAN bus.
8.3.12 Conguration of the serial interface on D7 (RDI=0xFD26)
See section 13.2
8.3.13 Conguration of the serial interface on D8 (RDI=0xFD26)
If the K-line or the information interface on the EFAS is to be used, then the interface must be congured. The parameter
RDI=0xFD26 is used to set the communications protocol. Details on the K-Line and the information interface are described in a
separate section13.2.
8.3.14 Monitoring of pulse output B7 (RDI=0xFD35)
The tachograph can monitor the pulse signal at output connector B7 to detect external short-circuits. This is important because
the B7 signal is used in some buses to control the door lock during driving and in some other vehicles as a control value for the
overs-peed control. If a short circuit is detected an error code (DTC) is set in the tachograph’s error memory. Monitoring can be
switched on or o with the parameter RDI=0xFD35.
8.3.15 Function of the pulse output D6 (RDI=0xFDA0)
Unlike the motion sensor outputs B6 and B7, the pulse output D6 can be output at dierent frequencies as required by some
vehicle types. This additional factor represents the number of output pulses from the motion sensor for a travel distance of 1 km.
This value is set according to the connected display instrument (e.g. 8000 pulses/km). The value is independent of the k-factor.
8.3.16 CAN Heart beat monitoring of a connected bus subscriber (RDI=0xF90C)
By means of this parameter the monitoring of CAN-“reset” messages may be switched o (see section13.1.4).
8.3.17 Transmission interval of the TCO1 message (RDI=0xF920)
By means of this parameter the transmission interval of the CAN-“TCO1”-message may be adjusted (see section13.1.4)
8.3.18 Conguration of FMS service (RDI=0xFD9E)
Use this parameter for conguring the FMS-service for remote data download. The automatic adjustment of the parameter is
done via CAN message “FMS identity” (PGN=0x00FDD1). When this message is detected on a CAN bus, the FMS-service will be
automatically activated for this CAN bus.
