3. To display correctly the PTO’s rotational speed (540 and 1000), it is necessary to pro-
gram the gear ratios of the PTO 540 “K3” and PTO 1000 “K4” from Table 9 and the num-
ber of teeth of the pinion at the place of installation of the PTO sensor “Z2” in the speci-
fied order:

- in case of absence of the PTO rotational speed sensor (from the phase winding of the
alternator serves as that for indication of the PTO rotational speed), the entered value of
the parameter “Z2” shall be equal to 0.
