Restriction of the control function!
Risk of death or injury, or property damage.
Moving parts in control and regulation systems (e.g. control spools) may in certain
circumstances become stuck in an undefined position due to contamination
(e.g. contaminated hydraulic fluid, abrasion or residual dirt from components). The
volume flow of the driven consumer will then no longer follow the commands of the
operator.
▶
Secure the machine against rolling away and unintentional movements
according to the specifications of the machine manufacturer.
▶
Observe the specified cleanliness level of the hydraulic fluid in accordance with
a data sheet.
Risk of pressurized hydraulic fluid leaking or fly-away parts!
Danger to life or risk of injury. If fasteners without sufficient high pressure
resistance are used, they can cause rupturing and leakage of hydraulic fluid and/or
fly-away parts. The ports and fastening threads of the control block are designed
for the specified maximum pressure.
▶
Only ever connect connecting elements and lines that match the ports of the
control block and can resist the intended application conditions (e.g. pressure
level, flow, hydraulic fluid, temperature) with the necessary safety factors.
Faulty power supply!
Danger to life or risk of injury due to uncontrolled valve settings! These settings can
lead to unexpected behavior of the control block.
▶
Always connect the ground connection of the control block to the corresponding
ground system in your installation.
▶
Only ever use a power supply unit with safe separation. Always take into
account your country-specific specifications.
