Commands

Additionally to the external analogue command

inputs (Pins 5-7 and 6-7), the PCD00A-400-elec-

tronic 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.

n 1, 2 2 – Allocation of internal command signals

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 pa-

rameter 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 con-

nection (RS232C-null modem) by the computer-

software.

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.

Connection Examples

Certainly combinations and / or modiﬁcations of these examples are possible. The priority of the digital

inputs over the analogue inputs has to be kept in mind! Via parameter N=1 all four digital inputs may

be dedicated to channel A.

Enable input and status output

The enable input activates (9...30 VDC) the power

ampliﬁers or deactivates them (0 VDC). The status

output delivers 18...30VDC during normal operation.

It switches to 0 VDC in case of an error.

Installation guide to electronic modules to provi-

sion 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 con-

nected 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.
