Hydraulical connection
•
The two hydraulic hoses (for opening and closing the device) on the carrier must be screwed onto the
two hydraulic connections on the valve block of the device (
VZ-H-UNI
).
•
A second control circuit is necessary if a rotating motor is integrated at the
VZ-H-UNI
.
•
In accordance with the enclosed hydraulic wiring diagram a unblockable
non-return valve
is built into the
(
VZ-H-UNI)
circuit to prevent, that the kerb stone does not fall down
,
loss of pressure.
•
Is there only one (two) hydraulic circuit on the lifting apparatus, you can split one of the circuits by using
a electromagnetic valve ELMV.
•
The hydraulic hoses must be free of breaks and abrasion. Take care that there are no outstanding edges,
where the hoses could hook in.

A faultless and reliable in operation function of the device (
VZ-H-UNI
) is ensured, if the following values are
adjusted.
Installed load:
optimal
minimal

To avoid disorders and failed functions it is absolute necessary, for every commissioning of the device
(
VZ-H-UNI
), to check the correct connection of the hydraulic hoses!
