“A” line sends oil under pressure to the deviator valve
, that is physically
included into the hydraulic manifold, this valve is commanded directly by the
control module to feed right side ground valveblock or to aerial part valveblock.
Deviator valve normally (when not fed) sends oil to aerial part valveblock, so
that it feeds right side ground valveblock only when its coil is energized.
Its coil is energized (oil to the right side ground part) when machine is ON but
not stabilized (or not respecting all the conditions to allow aerial part
movements) and with engine/electric motor running.
For instance, deviator coil is energized when, with engine or electric motor
running, all outriggers are touching the ground but remote control is not
placed on its support.
NOTE: On lithium machine deviator coil is always energized when machine is
ON and not stabilized (or not respecting all the conditions to allow aerial part
movements), doesn’t matter if engine/electric motor are running or not.
“B” line sends oil under pressure to the double pump valve
, that is physically
included into the hydraulic manifold, and that normally feeds left side ground
valveblock.
Double pump valve normally (when not fed) sends oil to left side ground
valveblock, so that it sends oil to the deviator only when its coil is energized.
While “N” or “HARE” speed is selected, whe
n some aerial part movement are
in progress, double pump valve is fed by the control module in order to feed
also with the second pump the aerial part valveblock, increasing the movement
speed even without increasing the rpm.
