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.
