Introduction
Scope
This manual provides information required for installation, operation,
and configuration of the DPRSOO Integral Controller.
Description of Manual
Section 1 = Introduces the user to the organization of the manual,
contents of other sections, and DPRSOO Controller specifications.
Section 2 = Describes the mechanical and electrical installation
procedures for the controller, including power and grounding
requirements.
Section 3 = Explains the functions and use of the front panel controls
and indicators.
Section 4 = A brief description of the procedures used to set
FCODE’s.
Section 5 = Instructions for configuring the DPRSOO Controller.
Appendix A = Fault Codes
Appendix B = FCODE Index
Appendix C = Field Replaceable Pans
The DPRSOO Integral Controller is a single-loop, proportional, integral,
derivative (PID), user-configurable controller. All controller functions
reside in the controller. Configuration consists of selecting the
appropriate functions and setting the tuning parameters, using the
controls and indicators on the front panel. Configuration may be
entered or changed while the controller is operating. The controller
scans and updates all input and output signals five times a second.
When the controller is communicating with a computer via the RS-485
serial interface, this I/O scan and update rate is not valid, due to
communications link limitations. Connection to and communication
with external equipment is via four analog and four digital inputs, two
analog and six digital outputs, and a serial data port (RS-485).
l-2
Introduction
The controller may communicate with a central computer system via
the RS-485 serial data communication channel. The communications
mode is half-duplex, using the COMLI communications protocol.
Two discrete inputs may be used to directly control either the output
signal or setpoint value. Other discrete inputs can switch the controller
to a remote or extra internal setpoint or a predetermined value. These
external discrete signals may also switch the controller between
different modes: Auto/Manual or Local/Remote.
The terminal block, which connects all input power and signal lines, is
at the back of a separate, permanently installed mounting cassette.
The controller slides into this cassette, eliminating the need to
disconnect cables or disturb the electrical installation when changing
a controller.
A configuration reference card is located in the slot behind the hinged
flap at the top of the controller’s front panel. It lists the controller
functions and tuning parameters. Space is provided for the user to
indicate the configuration and tuning values currently entered in the
controller.

Installation
Mechanical Installation
The DPRSOO Integral Controller units fit into a cutout in a vertical
panel, allowing for high packing density. The cutout may be for a
single controller unit or for multiple units mounted side by side. For
typical installations the panel must be between 0.06 inch (2 mm) and
0.16 inch (4 mm) thick. For installation information on thicker panels,
contact your Fisher Representative.
The figure shows a controller’s external dimensions, along with the
spacing and dimensions for panel cutouts. Front panel cutouts
conform to DIN standards.

Make the cutouts in the panel according to the dimensions and
spacing shown. For multiple installations, make the cutout wider
according to the following formula:
Cutout width (W) = N x B - 0.19 inch (4.5 mm)
where:
N = number of controllers to be mounted
B = unit width = 2.84 inches (72 mm)
Tolerance = + 0.04 inch (1 mm) per unit
Wiring the Mounting Cassette
The DPRSOO Integral Controller fits into a standard panel-mount
cassette. The mounting cassette has terminal blocks on the rear for
all electrical connections.
Connect all wiring to the terminal blocks before inserting the cassette
into the panel cutout unless the rear of the cassette will be accessible
after installation.

Power and Ground Wiring
The power source for the DPRSOO Controller should be free of
electrical noise. Do not use sources that supply power to relays,
contacts, or thyristor-controlled equipment. If no other source is
available, use an isolation transformer or magnetic voltage stabilizer.
Do not connect electrically noisy equipment and the DPRSOO to the
same secondary of such a transformer. Closely follow the
manufacturer’s recommendations concerning the grounding 01 the
isolation transformer.
When operating the controller from an alternating current source,
always use a 3-wire power cord. Connect the neutral wire to terminal
41 and the ground wire to terminal 42 on the terminal block. Connect
the supply line wire to the appropriate terminal for the power being
The controller operates on either 50 or

For proper operation of DPR products, it is essential that ground
wiring be installed as indicated. To reduce electrical noise and
interference and increase safety, connect separate ground wires from
each unit to the Local Ground Bus (LGB) in the cabinet or enclosure.
The ground wire from the LGB to the plant ground should be run in
plastic or other non-ferrous material conduit. Ground connection of
the same type, i.e. dc common connections, may be to the same point
on the LGB. Never intermix dissimilar grounds.
Terminal 36, the dc common and Terminal 42, the case ground,
should always be connected to the LGB. The remaining connections
are dependent on type of input power (AC or DC).
If 14 or 16 AWG wire is used to supply AC power, the incoming
ground wire should terminate at the LGB. A second wire should be
run from the termination point on the LGB to Terminal 42. If a smaller
wire size is used, connect the incoming ground wire to Terminal 42.
Then run a second wire from Terminal 42 to the LGB.
When considering the incoming wire size, ensure that any line loss
does not exceed the voltage tolerance of the DPR unit. A power
conditioner may be required.
If the unit is mounted in a metal panel or enclosure, the panel,or
enclosure must be grounded to the DPR. Use the terminals lugs at
the rear of the mounting cassette for this purpose.

The 24 Vdc terminal can supply a maximum
external load of 100 mA when powered from 110,
120,220 or 240 Vat power sources. This supply is
intended to power transmitters or relays connected
to the discrete outputs. The 100 mA limit applies
only to ac powered units. No internal load,
including the two analog outputs, need be included
in the 100 mA total.
Controllers powered from 24 Vdc sources have a
current limit of 250 mA on each output.
To operate the controller from a 24 Vdc supply, connect the power
supply leads to 24 V terminals 35 and 36 (observe the proper
polarity).
Signal Wiring
Connect all input and output wiring to the terminal blocks at the rear
of the mounting cassette. Use direct runs of individually shielded,
twisted-pair wire in an insulating jacket. The maximum wire size for
terminal connectors is 14 AWG (1 .5mm2). The insulating jacket
should only be stripped to allow the length of wire required to connect the twisted-pair to the terminals.
For long runs, it may be practical to route field wiring to a junction
box, then through multi-pair shielded cable. Lace wires as required
by local electrical codes or plant standards. Connect the shield and
drain wires to the grounding bus bar as shown. Standard practice is
for shields to be grounded at the signal source only. If the shield is
grounded at the DPR (vs the external instrument), also tie it to the
LGB. Shield wires should not be stripped further than one inch from
the end of the signal wires.
Route a 14 AWG (1.5 mm*) conductor from the mounting cassette
ground to the panel ground point. Then use an AWG 8 (8.37 mm2)
multistrand conductor or 0.50 inch (12.7 mm2) braided ground
conductor (preferred) to connect the panel ground point to the LGB.
The panel ground point and the ground of the ac power source for the
unit should be connected to the same grounding bus bar. This
minimizes the possibility of significant voltage between ground points.
Use crimped or thermal-welded connections at all ground points.

Route a 14 AWG (1.5 mm*) conductor from terminal 36 to the
instrumentation system dc ground point. Then run a 10 AWG (5.26
mm*) multistrand conductor from the instrumentation system dc
ground point to the existing plant ground grid. This point on the plant
ground grid must be dedicated exclusively to the instrumentation
system dc ground and must not be used for other equipment
grounding. Use crimped or thermal-welded connections at all ground
points.
Jumper Module
@
Caution
Ensure that power to the controller is OFF,
prior to cutting jumpers. Leave sufficient
metal to solder jumper back together if
required.
The jumpers on the back of the mounting cassette determine the
electrical termination characteristics of the four analog inputs and the
RS-485 communications wiring. All of the analog inputs, All thru Al4,
have 250 ohm input resistors. There is also a 100 ohm termination
resistor on the RS-485 connection. The figure shows the jumper
module and the table describes the connection each jumper makes.

Jumpers 1 thru 4 connect the 250 ohm input resistors in series so
that the 4-20 mA input signal can be converted to a I -5V signal inter-

Jumper 9 is used to terminate the last controller on the RS-485
communication link. When the link is used, this jumper must be cut on
all but the last controller on the link. Otherwise, it should remain intact.

Low-Level Temperature Input
A DPRlOO Series Temperature Input Module may be plugged into the
controller to allow direct connection of a low-level input signal. The
controller internally connects this input to All. This disables All for
other uses. For further information on the DPRlOO, refer to Fisher
Controls Bulletin 6.1 :DPRlOO. The figure illustrates the wiring of the
temperature input module.

Analog Input Signals
Connect analog inputs All thru Al4 to the appropriate terminals on
the back of the mounting cassette. Some examples of connections
are shown in the figure. Select the Al signal ranges (O-20 mN4-20
mA or O-5 V/l -5 V) during configuration as explained in Section 5.
Ensure that shields are connected to chassis ground by using either
of the two lugs at the upper edge of the rear panel.
If a Pt-100 sensor or thermocouple is used without a transmitter, it
must be connected directly to a DPRIOO Temperature Input Module
mounted on the module block. This disables the use of All for any
other signal.
D For voltage Inputs the
resistance jumper
must be cut.
The DPRSOO accepts signals from field-powered transmitters and
can supply the required 24 Vdc to most remotely-powered
transmitters. The figures show how to connect external sensors
powered either by the controller or by an external source. The
terminal block connector numbers for All are shown, although the
connection information applies to all analog inputs.

Analog Output Signals
Two analog outputs are available on the DPRSOO and
both deliver a 4-20 mA/O-20 mA signal proportional to
the 6100% selected output signal. The controller PID
output signal is always available at AOI. A02 is a re-
transmission of a user selected internal signal value.
Connect the analog output signal wires to terminals 9 and
10. Configure the output signal range using FCODE 116.

If an actuator position feedback potentiometer for a positioning
motor output is required as shown in the figure. The potentiometer
is connected to A01 where the current input will be supplied.
The negative input of any Al must be jumpered to
supply ground when the potentiometer setup is
used.
Digital Input Signals
All digital input signals (Dll thru D14) to the controller are isolated
by opto-couplers. The input current source may be from the
controller or from an external power supply as shown.
