WARNING
SYSTEM 4000 must be mounted on a DIN rail according to DIN
46277.
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 instruc tions of this manual must be observed and the
guidelines fol lowed. 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 disconnected device and under ESD safe conditions:
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
Do not open the front plate of the device as this will cause damage
to the connector for the display / programming front PR 4501. This
device contains no DIP-switches or jumpers.

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.
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,

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.
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 indicating that it will switch off the
volt age to the device.
Year of manufacture can be taken from the first two digits in the serial number.
UL INSTALLATION REQUIREMENTS
Use 60/75°C copper conducters only.
For use only in pollution degree 2 or better.
Max. ambient temperature ............................ 60°C
Max. wire size ...................................................... AWG 26-14
UL file number .................................................... E231911
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
custom er cannot advance a demand against PR electronics A/S that would otherwise exist according to the concluded sales agreement.

UNIVERSAL I/f CONVERTER
4222
• Input for RTD, TC, Ohm, potentiometer, mA and V
• Frequency output NPN, PNP and TTL
• Generates frequencies from 0.001...25000 Hz
• 2-wire supply > 16 V
• Universal AC or DC supply
Advanced features
• Programmable by way of detachable display front (4501), process calibration,
signal simulation, password protection, error diagnostics and help text available
in several languages.
Application
• Linearised, electronic temperature measurement with RTD or TC sensor.
• Conversion of linear resistance variation to a frequency signal, e.g. from solenoids
and butterfly valves or linear movements with attached potentiometer.
• Power supply and signal isolator for 2-wire transmitters.
• Process control by way of a frequency signal transmitted to e.g. a PLC or a process
computer.
• Galvanic separation and conversion of analogue signals to frequency signals.
Technical characteristics
• When 4222 is used in combination with the 4501 display / programming front,
all operational parameters can be modified to suit any application. As the 4222
is designed with electronic hardware switches, it is not necessary to open the
device for setting of DIP-switches.
• A green front LED indicates normal operation.
• Continuous check of vital stored data for safety reasons.
• 3-port 2.3 kVAC galvanic isolation.

PR 4501 DISPLAY / PROGRAMMING FRONT
Functionality
The simple and easily understandable menu structure and the
explanatory help texts guide you effortless ly and automatically
through the configuration steps, thus making the product very
easy to use. Functions and configuration options are described in
the section ”Configuration / operating the function keys”.
Application
• Communications interface for modification of operational parameters in 4222.
• Can be moved from one 4222 device to another and download the configuration
of the first converter to subsequent converters.
• Fixed display for readout of process data and status.
Technical characteristics
• LCD display with 4 lines; line 1 (H = 5.57 mm) shows input signal, line 2
(H = 3.33 mm) shows units. Line 3 alternates between digital output value and
scaling (kHz, Hz, mHz, P/m, P/h, P/d) or shows TAG no. Line 4 shows tendency
readout for the input signal and communication status.
• Programming access can be blocked by assigning a password. The password is
saved in the converter in order to ensure a high degree of protection against
unauthorised modifications to the configuration.
Mounting / installation
