Dismantlement of the device for setting of dipswitches
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

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 device without damaging it. The packing should always follow the
device until this has been permanently mounted. Check at the receipt of the device
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.
MOUNTING
Only technicians who are familiar with the technical terms, warnings, and
instructions 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.a. wire cross section, protective fuse, and location.
Descriptions of input / output and supply connections are shown in the block
diagram and side label.

6 5225V101-UK
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.
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 the instructions in this manual are not strictly observed, the customer
cannot advance a demand against PR electronics A/S that would otherwise exist
according to the concluded sales agreement.

HOW TO DISMANTLE SYSTEM 5000
First, remember to demount the connectors with hazardous voltages. By lifting the
bottom lock, the device is detached from the DIN rail as shown in picture 1.
Then, by lifting the upper lock and pulling the front plate simultaneously the PCB
is removed as shown in picture 2.
Switches and jumpers can now be adjusted. By opening the front, the programming
connector is accessible as shown in picture 3.

----------------------------------------------------------------------------------------------------------------
IN GENERAL
By way of a standard PC and the Loop Link programming kit, the 5225 f/I - f/f
Converter is configured acc. to the requested function.
Alternatively, the 5225 may be delivered fully-configured acc. to your
specifications.
Typical pulse sources are flow meters, tacho generators, mechanical switches, or
inductive proximity sensors.

5225V101-UK 9
APPLICATIONS
The f/I function performs frequency to current and voltage conversion.
The output can be programmed to show period meaning that the input frequency
can be converted to a linear time signal.
The digital outputs are used as e.g. a frequency watch for speed control or as a
window comparator having one status between 2 limits and the opposite status
outside these limits.
The f/f function can be used for pulse division or multiplication and as a buffer
collecting fast pulse trains. The input pulses are calculated, counted in a buffer, and
sent to the output as a pulse train with the programmed pulse width.
The concurrent f/I and f/f functions enable a scaled digital output signal in
conjunction with the analogue output.
The frequency generator function is used as e.g. a time base or clock
generator.
TECHNICAL CHARACTERISTICS
INPUT
Programmable input for standard pulse generator connection.
Normally, the auxiliary supply and trigger level follow the sensor type, but these
can be programmed acc. to other values.
At contact input, the 50 Hz filter should be applied.
The PRecon 5225 is protected against polarity reversal on input and supply.
ANALOGUE OUTPUT
The analogue current and voltage output can be scaled acc. to your choice in
relation to the digital input. Max. zero offset is 50% of selected measurement
range. Programmable response time.
Short circuit-protected output.
When both current and voltage signals are used simultaneously, the mA loop to
ground passes through the internal shunt.
Standard voltage output (pin 12) is obtained by leading the current signal (pin
13) through an internal shunt resistor (pin 12). At current signals in the ranges
0...1 VDC, a 50 Ωshunt (JP1) is applied; in the ranges 0...10 VDC, a 500 Ωshunt
(JP2) is applied.

10 5225V101-UK
DIGITAL OUTPUT(S)
Both NPN / PNP and relay outputs can be set up with delayed on and off. The
action on the outputs can be inverted, and the hysteresis can be set acc. to your
specifications.
At power-up, shifts on the outputs can be delayed for up to 999 s.
NPN and PNP outputs for external relay, electromechanical counter, PLC input, or
equivalent load.
The outputs are current-limited by way of PTC resistors.
Active output is established by connecting the NPN to the PNP output (jumper
pins 22-23).
RELAY OUTPUTS
The PRecon 5225 can be delivered with 2 relay outputs that are programmed
individually.
STATUS INDICATION
The 5225 is equipped with 4 front LEDs.
f in: Indicates an active input (non-active at NPN input).
Dig. out. 1: Indicates active NPN or relay 1 output.
Dig. out. 2: Indicates active relay 2 output.
Error: Indicates sensor error at NAMUR input.
