WARNING
This device is designed for connection to hazardous electric
voltages.
Ignoring this warning can result in severe personal injury or
mechanical damage.
To avoid the risk of electric shock and fire, the safety instructions
of this manual must be observed and the guidelines followed.
The specifications must not be exceeded, and the device must
only be applied as described in the following.
Prior to the commissioning of the device, this manual must be
examined carefully.
Only qualified personnel (technicians) should install this device. If
the equipment is used in a manner not specified by the
manufacturer, the protection provided by the equipment may be
impaired.
WARNING
Until the device is fixed, do not connect hazardous voltages to
the device.
The following operations should only be carried out on a discon-
nected device and under ESD safe conditions:
Dismantlement of the device for setting of DIP-switches
and jumpers.
General mounting, connection and disconnection of wires.
Troubleshooting the device.
Repair of the device and replacement of circuit breakers must be
done by PR electronics A/S only.
WARNING
SYSTEM 5000 must be mounted on DIN rail according to DIN
46277.
The communication connector of SYSTEM 5000 is connected to
the input terminals on which dangerous voltages can occur, and
it must only be connected to the programming unit Loop Link by
way of the enclosed cable.

SYMBOL IDENTIFICATION
Triangle with an exclamation mark: Warning / demand.
Potentially lethal situations.
The CE mark proves the compliance of the device with
the essential requirements of the directives.
The double insulation symbol shows that the device
is protected by double or reinforced insulation.
Ex devices have been approved for use in connection
with installations in explosive areas.
SAFETY INSTRUCTIONS
DEFINITIONS
Hazardous voltages have been defined as the ranges: 75 to 1500 Volt DC, and
50 to 1000 Volt AC.
Technicians are qualified persons educated or trained to mount, operate, and also
troubleshoot technically correct and in accordance with safety regulations.
Operators, being familiar with the contents of this manual, adjust and operate
the knobs or potentiometers during normal operation.
RECEIPT AND UNPACKING
Unpack the module without damaging it. The packing should always follow the
module until this has been permanently mounted. Check at the receipt of the
module whether the type corresponds to the one ordered.
ENVIRONMENT
Avoid direct sunlight, dust, high temperatures, mechanical vibrations and shock,
as well as rain and heavy moisture. If necessary, heating in excess of the stated
limits for ambient temperatures should be avoided by way of ventilation.
All devices fall under Installation Category II, Pollution Degree 1, and Insulation
Class II.

4 5115V104-UK
MOUNTING
Only technicians who are familiar with the technical terms, warnings, and instruc-
tions in the manual and who are able to follow these should connect the device.
Should there be any doubt as to the correct handling of the device, please contact
your local distributor or, alternatively,
PR electronics A/S
www.prelectronics.com
Mounting and connection of the device should comply with national legislation
for mounting of electric materials, i.e. wire cross section, protective fuse, and
location. Descriptions of input / output and supply connections are shown in the
block diagram and side label.
The following apply to fixed hazardous voltages-connected devices:
The max. size of the protective fuse is 10 A and, together with a power
switch, it should be easily accessible and close to the device. The power
switch should be marked with a label telling it will switch off the voltage
to the device.
Year of manufacture can be taken from the first two digits in the serial number.
CALIBRATION AND ADJUSTMENT
During calibration and adjustment, the measuring and connection of external
voltages must be carried out according to the specifications of this manual. The
technician must use tools and instruments that are safe to use.
NORMAL OPERATION
Operators are only allowed to adjust and operate devices that are safely fixed in
panels, etc., thus avoiding the danger of personal injury and damage. This means
there is no electrical shock hazard, and the device is easily accessible.
CLEANING
When disconnected, the device may be cleaned with a cloth moistened with
distilled water.
LIABILITY
To the extent that the instructions in this manual are not strictly observed, the
customer cannot advance a demand against PR electronics A/S that would other-
wise exist according to the concluded sales agreement.

HOW TO DEMOUNT SYSTEM 5000
First, remember to demount the connectors with hazardous voltages.
Picture 1:
Detach the device from the DIN rail
by lifting the bottom lock.
Picture 2:
By lifting the upper lock and pulling
the front plate simultaneously the
PCB can be removed
Switches and jumpers can now be
adjusted.

FUNCTION DESCRIPTION
In general:
Output 1 and output 2 can be configured for standard current / voltage signals
in the ranges 0/4...20 mA and 0...10 VDC. When selecting the arithmetical
functions, up to 4 constants, K1, K2, K3, and K4, must also be defined.
The functions can be selected individually for both outputs. Duplication of the
signal from e.g. input 1 is obtained by selecting the function Input 1 for both
output 1 and output 2.
Selection of functions for the outputs (to be selected in the configuration
program PReset):
Input 1:
Input 1 is transmitted directly to the selected output.
Input 2:
Input 2 is transmitted directly to the selected output.
Addition: (Input 1 *K1 + Input 2 *K2 + K4)
After calculation, the result of the addition is transmitted to the selected
output.
Example 1:
When adding 2 identically scaled input signals of e.g. 4...20 mA, the output
would be 8...40 mA at the same scaling. But as the output follows standard
current signals of 0/4...20 mA, the scaling on the output is double of the
scaling on the inputs. This means that each input must be scaled by only half
the scale of the output. This is done by setting K1 and K2 at 0.5.
The offset constant K4 will typically be 0.
Example 2:
When adding 2 differently scaled input signals, K1 and K2 can be calculated as
follows:
Input 1: 4...20 mA corresponding to a flow of 0...100 m3 / h.
Input 2: 4...20 mA corresponding to a flow of 0...150 m3 / h.
The output signal of 4...20 mA must correspond to a flow of 0...250 m3 / h.
Input 1 must be scaled by 100/250 corresponding to a K1 of 0.4.
Input 2 must be scaled by 150/250 corresponding to a K2 of 0.6.
The offset constant K4 will typically be 0.
