Power Supply

The utilized power supply has to comply with the EMC-standards.

Relais and solenoids operating from the same supply circuit as the valve electronics have to be fitted by surge protection elements.

Wiring Cable

The wires between the installation site of the module and the peripheral units, as power supply, valve sole- noids, command signal source have to be shielded. The following wire sizes must be reached: power supply and solenoids AWG 15, other connections AWG 20.The capacity should not exceed a value of approx. 130 pF/m (wire/wire). The maximum cable length is 50 m.No power current lines may be placed within the wired shielded cables to the electronic module. The cable shield has to be connected to ground at both ends (see also chapter“Grounding“). Please be aware of ground loops.

Installation

The module has to be mounted within a conductive, shielded enclosure.Usable is i.e.an EMC-approved control cabinet.A perfect grounding of the enclosure is mandatory (see also chapter “Grounding“).

Grounding

The mounting plate of the valve has to be connected to the grounded metal machine frame. The cable shields must be tied to ground at the control cabinet. A low-ohmic potential compen-sation wire has to be provided between the control cabinet and the machine frame (cable wire >AWG 7 cross section) to prevent ground loops.
