WARNING
Faulty assembly, leaking hydraulic fluid!
Carelessly or incorrectly mounted valves may become loose during operation,
fall down and cause serious injuries. A powerful hydraulic fluid jet may leak at
incompletely mounted hydraulic connections and connection lines and cause
serious injuries.
▶ Only commission the system after all hydraulic connections and the valve
have been completely and properly mounted according to the specifications.
▶ Look out for defective sealing points and exchange defective seal rings
immediately.
▶ Wear personal protective equipment during the initial commissioning.
Inadmissibly high operating pressure!
In hydraulic applications with different area ratios, the hydraulic pressure is
fortified and may - in case of incorrect design - lead to exceedance of the maximum
admissible operating pressure. Valves may burst, or the cap elements may fly
around and cause serious injuries.
▶ Ensure before the commissioning of the hydraulic system that the maximum
admissible pressure of the valve in the system is not exceeded by any means.
▶ Ensure that in your system, the maximum admissible operating pressure is
secured by means of a pressure relief valve.
Commissioning by persons without the required knowledge!
Danger of damage to property and personal injuries. Commissioning of the valve
requires basic hydraulic and electrical/electronical knowledge.
▶ The valve may only be commissioned by qualified staff.
8.1 First commissioning
▶ Prior to commissioning, make sure that all electrical and hydraulic connections
are either used or covered. Commission the product only if it is installed
completely.
▶ Make sure that only hydraulic fluid specified in the valve data sheet is used.
▶ Allow the valve to acclimatize for some time prior to commissioning as the
electronics might be damaged by the generation of condensed water.
▶ Immediately depressurize the system if hydraulic fluid still leaks despite proper
assembly and continue with chapter 14 "Troubleshooting".
