New supply electronic board 12V/5V for SAUER
sensors
TECHNICAL SERVICE INFORMATION G05-0001 Date
30.08.2005 Brand Grégoire Model G117 G122
G170 et G140SW Subject Supply electronic
board 5Volts Kit N 167481 Modification
on machine equipped with a R.V.P. and having
SAUER wheel motors Availability 30.08. 2005
It was reported to us recently that a short cut
of a SAUER wheel sensor could generate an
electric overload on the 5 volts delivered by
calculator R.V.P. and cause a disturbance of the
hydrostatic system. A supply electronic board
must be installed on all the machines equipped by
a R.V.P. and SAUER wheel motors. This electronic
board makes it possible to supply the two rear
wheel sensors independently of the linear
potentiometer and the 5 turns potentiometer.
Moreover, it makes it possible to isolate the
wheel sensors circuit of the other electric
circuits of the machine. This kit is only
applicable to the G117, G122, G140SW and G170
machines, been driven with R.V.P. and SAUER wheel
motors. The machines equipped with R.V.P. and
POCLAIN wheel motors are not concerned.
