lift cylinders causing them to extend. The gear motor will automatically shut off once the
programmed pump upper limit is reached.
4.2 Retraction Cycle
(Refer to
Movotec
®
Q-Drive Schematic
on page 7)
When the motor switch
“DN”
arrow button is depressed, the 24VDC gear motor shaft
begins to rotate in a
(CW)
clockwise direction. Since the gear motor shaft is
mechanically coupled to the pump leadscrew shaft, the leadscrew shaft rotates in the
same
(CW)
direction. As the gear motor continues to rotate in a
(CW)
direction, the
threaded pusherblock moves down the leadscrew in the direction of arrow
“B”.
As long
as there is sufficient load on the lift cylinder piston rods, the fluid in the lift cylinders
flows back through the hydraulic tubing and into the pressure elements. The gear motor
will automatically shut off once the programmed pump lower limit is reached.
5.0 Unpacking Instructions
The system comes packaged in a cardboard carton. To unpack the system:
•
Check the carton label to confirm that you have received the correct system; open
the carton and remove packaging material.
•
Carefully remove the system from the carton, and verify all components are
present (reference chart below), and that the correct lift system was received.
Do not handle the lift cylinders and motorized pump by the hydraulic tubing. Incorrect
handling of hydraulic tubing could weaken the tubing material and system tubing
connections.
DAMAGE TO TUBING OR TUBING CONNECTIONS
COULD CAUSE FLUID LOSS AND UNCONTROLLED
DESCENT OF THE WORK-SURFACE.
