Installation and debugging

Preparation of installation tools

A set of Phillips screwdriver, adjustable wrench, and Allen wrench

Oil circuit connection

After adding hydraulic oil, connect the main engine to the control cabinet using the randomly provided rubber hose, as shown in the figure. Please keep the oil plug at the unscrewed pipe joint properly to avoid loss and inconvenience in moving the machine in the future. The connection must be tight and sealed with a gasket.

Electrical Connection:

Remove the entire set of data cables from the host and connect them to the left interface of the oil source cabinet according to the data cable markings.

When connecting the power cord, please strictly follow the power cord label that comes with it.

Open the packaging of the random computer and install it (this step is only applicable to models with computer configuration); After installing the computer, connect one end of the random communication cable RS-232 to the controller communication serial port and install the other end on the computer host communication serial port. Please do not replace the random computer (with built-in measurement and control software and factory calibration parameters)

Initial operation and test drive:

Connect the power supply to raise the center beam a certain distance (ifLiangWhen descending, the operation should be stopped immediately and the phase sequence of the main power supply should be adjusted. Then, according to the longitudinal requirements in the user manual, the equipment should be operated without load. During the process of the worktable rising (not exceeding the maximum stroke), observe for any abnormal phenomena. If there are, it should be unloaded and stopped for inspectioncheck, troubleshooting; If none, unload to lower the piston to its original position and end the debugging of the equipment.
