Characteristics

Electronic module for the control of proportionalthrottle valves. The valve opening and its changesare achieved by command and ramp poten-tiometers. The measured value (Volts) on themodule is indirectly proportional with the throttleopening or alternatively the resulting volume flowQ (l/min). )(

INSTALLATION GUIDE TO ELECTRONIC MODULESTO PROVISION OF ELECTROMAGNETIC COMPATIBILITY.

Power Supply

The utilized power supply has to comply with the EMC-standards (CE-sign, certificate of conformity).Parker is offering the following power supplies:

EX00-N01 ( 2.5 Amp.)EX00-N04 ( 5.0 Amp.)EX00-N08 (10.0 Amp.)

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

Wiring Cable

The wires between the installation site of the module and the peripheral units, as power supply, valvesolenoids, command signal source have to be shielded. The following wire sizes must be reached:power supply AWG 16, 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 withinthe wired shielded cables to the electronic module. The cable shield has to be connected to groundat 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 cableshields must be tied to ground at the control cabinet. A low-ohmic potential compensation wire hasto be provided between the control cabinet and the machine frame (cable wire >AWG 7 cross section)to prevent ground loops.
