Blocking And Automatic Gear Change Of Multiplier - Zetor PROXIMA POWER Z90 2012 Operator's Manual

Recommendations:
Prior to turning on the controller of multiplier pre-selection on dashboard, shift manually while driving a multiplier gear by means
of H and L buttons (once with H button and once with L button) on a gear lever with requested engine revolutions. The values
(engine revolutions) are saved and with subsequent switch of the controller of multiplier pre-selection on dashboard, the system
of automatic gear change of multiplier will shift the gears of multiplier automatically according to these engine revolutions.
With a controller of pre-selection multiplier on, in the event of travel clutch release, for example while shifting gears, stopping and
subsequent starting of a tractor or while using reversal, the system of automatic multiplier shift with subsequent closure of taxing
clutch sets a suitable gear of multiplier automatically.

BLOCKING AND AUTOMATIC GEAR CHANGE OF MULTIPLIER

If brake pedals are used with the controller of multiplier pre-selection on, the system of automatic gear change of multiplier blocks
the automatic shift of multiplier to a higher gear (increasing taxing speed), automatic shift of multiplier to lower gear (lowering tax-
ing speed) remains in operation.
Cancelling the blockage:
a - In the event when brake pedals were used with taxing speed higher than 12 km/h, the full-function of the system of automatic
gear change of a multiplier is reset by releasing brake pedals and pressing any key for multiplier operation on gear lever (H
or L) or we release a travel clutch. The full function of the system of multiplier automatic shift is not renewed auto-
matically.
b - If the brake pedals are used with taxing speed lower than 12 km/h, the full function of the system of automatic shift of multi-
plier will be renewed automatically after releasing brake pedals.
Blocking of automatic gear change of multiplier serves for the need of braking with an engine, e.g. while going down the
slope.
