GENERAL OVERVIEW CONTINUED
•
NOTES:
While in Manual operation mode only one cylinder may be operated at a time.
System pressure should be low enough, there will be cylinder movement, but not high
enough to allow the load to be lifted.
• Depending upon the length of hoses and the size of the cylinder’s used as well as the
length of the initial stroke it may be necessary to add additional oil to the tank.
• In any circumstance it is recommended to use pre filled hydraulic hoses with the same oil
as the rest of the system before any lift is performed.
• While manually raising a cylinder, disconnect the connector wire from the position sensor at
that cylinder and confirm that an alarm response is received and the system stops
operating.
• Reattach the cable and touch re-set button on home page to continue testing.
CYLINDER APPROACH TO LOAD
(Set the system into Manual mode)
There is NO control of the actual movement of the load in the manual mode!
Set
the maximum pressure to a setting that allows the plunger of each cylinder to move.
However, this pressure setting must be low enough such that the cylinder cannot move
the load, but only make firm contact with the load to be lifted.
During this operation the plunger of each cylinder will come into contact with the
lifting point of the load. This can cause a pinch point. Make sure all personnel
stand clear from moving plungers.
IMPORTANT:
Too high of a pressure setting can cause a cylinder to start moving
the load and cause unduly stress or even damage to the structure to be moved.
Activate each circuit one by one until the plunger is in full contact with the load
and the pre-set max pressure has been reached.
