Commands
Additionally to the external analogue command inputs (Pins 5-7 and 6-7), the PCD00A-400-elec­tronic includes, for each channel, two internal programmable command values S1 to S4, which can be activated by the switching inputs (Pins 13, 14, 15, 16). S1 (Pin 13) has a higher priority than
Signal Flow Diagram A
S2 (Pin 14) and S3 (Pin 15) has a higher priority than S4 (Pin 16).
If only one amplifier channel is used, it is possible to switch all four internal commands to this channel by setting parameter N=1.

All parameters are saved in an EEPROM and become active directly after supply voltage is switched on.
Ramp-function / Min-Max-function
The PCD00A-400-electronic includes two internal programmable ramps for each channel. Addition-
ally a current step may be programmed (Min) and / or the current may be limited (Max) for each
Nominal current adjustment
The nominal current can be adjusted by one pa­rameter separately for each channel (Pin 9, 10, or 11, 12). The default nominal current is 800 mA.
Parameterization
All parameters can be adjusted via a serial con­nection (RS232C-null modem) by the computer­software. The computer-software shows the parameters in textform. So they are easy to use.
The connected valves may not operated
before loading an appropriate parameter set from the PC into the module electronics.

Installation guide to electronic modules to provi­sion of electromagnetic compatibility
Power Supply
The utilized power supply has to comply with the EMC-standards (CE-sign, certificate of conformity).
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 solenoids, position transducer, 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 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 compensation wire has to be provided between the control cabinet and the machine frame (cable wire >AWG 7 cross section) to prevent ground loops.
