6 Pressure control valve
The pressure control valve (
arrow) is factory
set to ca. 210 bar.
Prevents a sudden lowering of the lift in the
event of a leak in the hydraulic hose (lowering
speed = max. 1.5 x default speed).
7 Lowering valve (emergency release) and
emergency manual valves
●
Pos. 7.1 Lowering valve for emergency re-
lease of the main lift or the rolling jack
(Fig. 12 = default configuration).
●
Pos. 7.2 and 7.3: Emergency manual valve
for main lift and rolling jack. Fitted differently ac-
cording to variant. Before use check assignment
to main lift and rolling jack
.
During a power failure the valves close and
stop any movement.
8 Broken cable and slack cable switch
●
Pos. 8.1: Broken cable switch:
This switch is activated if the cable is broken. All
movement of the post lift stops immediately. The
control buttons will not function. Consult a com-
petent person for repair.
●
Pos. 8.2: Slack cable switch:
This switch is activated when the cable is too
slack. All movement of the post lift stops imme-
diately. The Down button will not function. The
Up button will however function in order that the
cable can be pulled tight again by raising the lift
slightly.
