7�5�7 Connecting the control block hydraulically
Dangerous movements of the hydraulic consumers!
Risk of injury due to incorrect pin assignments or mixed up cable connectors
because of inadvertent consumer movement!
▶ Make sure that all the pipes and/or hoses have been attached to the correct
control block port and have not been mixed up under any circumstances.
▶ After completing connection work, check that the cable connectors are
correctly assigned to the respective control block solenoids.
Damage due to improper installation!
Hydraulic lines and hoses which are installed under tension create additional
mechanical forces during operation which reduce the service life of the control
block and the entire machine.
▶ Install hydraulic lines and hoses without mechanical stress.
The machine manufacturer is responsible for dimensioning the lines. The control
block must be connected to the rest of the hydraulic system in accordance with
the hydraulic circuit diagram of the machine manufacturer.
The ports and fastening threads are designed for the maximum pressure
specified in the data sheet. The machine manufacturer must ensure that the
connecting elements and lines correspond to the specified application conditions
(pressure, flow, hydraulic fluid, temperature) with the necessary safety factors.
Only connect hydraulic lines that are appropriate for the control block port
(pressure level, size, system of units).
Observe the following notices when routing hydraulic lines.
• Lines and hoses must be installed without pre-charge pressure so that no further
mechanical forces are applied during operation that will reduce the service life of
the control block and possibly of the entire machine.
• Remove any resinification that has been created due to improper storage.
• Use suitable seals as sealing material.
– Observe the sealing capability of the hydraulic fluid used.
– Use the provided seal at each hydraulic port.
– Pay attention to cleanliness and integrity of the connections.
• Make sure the connections and connecting elements are airtight.
• Pressure lines
– For the pressure lines, use only pipes, hoses and connecting elements rated
for the working pressure range specified in the data sheet. These must also be
pressure resistant against the external air pressure.
• Drain line
– Always route the drain lines in a way that the control block is always filled with
hydraulic fluid and even during extended standstill periods cannot be emptied
hydraulically.
