The stroke limit can be entered after clicking the appropriate
textbox. For lifting, the stroke limit has to be larger then the
maximum stroke value; for lowering, the stroke limit has to be
smaller than the minimum stroke value.
After entering tolerance and stroke limit, the movement can be
started by clicking either automatic up or automatic down. Lifting or
lowering will be stopped when the tolerance is exceeded. In this
case the reason for the deviation has to be found and eliminated.
After that, the deviation can be removed either by driving single
cylinders in the manual mode or by switching of the deviating
cylinder for a short period.
NOTE: If cylinder positions are reset to zero after lifting, the load
cannot be lowered unless a minus (-) sign is entered before the
stroke limit.
NOTE: Movement can be stopped at anytime either by clicking the
command button STOP or by hitting any key on the keyboard
(except the return or space bar key).
10.3 Automatic Mode - Stroke Step Function (Special)
The special mode is activated by clicking the appropriate control
box. This mode allows a higher accuracy of the synchronize
movement while the speed of the movement is reduced.
The operation of the program in the SPECIAL mode is similar to
the description in Section 10.1. This mode allows to enter a step
width, in addition to the above mentioned entries. The smaller this
time is chosen, the better will be the accuracy of the synchronous
movement, but the speed of the movement will decrease. Useful
step widths are between 0.1 and 0.3 sec.
10.4 Automatic Mode - Load / Pressure
Choosing the automatic mode LOAD, all activated circuits will be
operated until the first circuit has reached the preset load. It is to
be remarked, that, depending on cylinder-capacity, flow and load,
increase and decrease of the pressure might happen very quickly,
so that the preset target-value might be exceeded.
10.5 Exiting the Program and Disassembly
Before switching off the system, check that all hydraulic hose are
vented and have no pressure. If not, the appropriate circuits have
to be relieved by extending or retracting in manual mode for a short
period.
To exit the program click on the EXIT command button. After that,
exit Windows and power off the PC. After switching off the master
switch of the electric control, all electric cords, connection cords off
the displacement sensors can be uncoupled and stowed carefully.
All electric couplers have to be protected from moisture. Hydraulic
couplers have to be protected by dust caps after uncoupling.
WARNING: This system is not intended as a load
holding device. When holding a lifted load, the system
may periodically cycle the valves on/off to make up for
any leakdown which might occur. Extended periods of load
holding require blocking (cribbing) the load. Failure to do so
could result in personal injury and/or property damage.
11.0 MAINTENANCE
Refer to supplied manufacturers maintenance literature for
recommended component maintenance.
