8 Commissioning
WARNING
Faulty assembly!
If the valve is not correctly mounted, persons might be injured and the valve
or system could be damaged when commissioning the valve.
▶
Only commission your 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.
▶
The solenoid coil may only be commissioned if mounted to the valve including
pole tube and mounting nut and if the protective grounding conductor and the
connection for potential equalization conductor are connected.
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. Thus, valves may burst, or the cap
elements may be ejected and cause personal injury.
▶
Before commissioning the hydraulic system, ensure 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 limitation element.
Damage to persons and property!
Commissioning the valve requires basic hydraulic and electrical knowledge.
▶
Only qualified personnel (see section 2.4 “Qualification of personnel”)
is authorized to commission the valve.
NOTICE
Risk of short-circuit!
Condensed water can build up in the terminal box and cause a short-circuit!
▶
Allow the valve to acclimatize for some hours prior to commissioning as the
electric connections in the terminal box might be damaged by the generation
of condensed water.
