Adjustment of the hydraulic control
●
The hydraulic control is adjusted for an operating pressure
(operating pressure of the carrier
–
e.g. excavator) of
about 200 bar.
●
Should the HVZ are mounted to a carrier with a higher
operating pressure (e.g. 200 bar or higher) must first be
checked, if the complete sequence (close and reopen)
works without problems.
●
If the case occurs, that the main clamping (HSP) is already
opened, when the side clamping (SSP) is opening, the
bypass valve (1) needs to be open slightly.
5.3
Setting 170 bar and 200 bar
The bypass valve (see
) integrated in the control unit allows the hydraulic control to be adapted to carrier
machines (crane) with various oil flow rates. For loaders with large oil capacities, the bypass valve is opened even
wider (200 bar). On carrier machines with small oil capacities, the bypass valve is closed (170 bar).
Setting the side clamping / main clamping
Approx. 2 turns to the left to "+" = side clamping
and main clamping open simultaneously.
Approx. 2 turns to the right to "-" = first the side
clamping opens and only then does the main
clamping open.
