WARNING

This device is designed for connection to hazardous electric volt-

ages. 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

electrical 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 manufac-

turer, 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:

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

To keep the safety distances, devices with two built-in relays must

not be connected to both hazardous and non-hazardous voltages

on the same device’s relay contacts.

SYSTEM 2200 must be mounted in socket type S3B Releco (order

no 7023).

GENERAL

2202V107-UK 3

SYMBOL IDENTIFICATION

Triangle with an exclamation mark: Warning / demand. Potentially lethal

situations.

The CE mark proves the compliance of the device with the requirements

of the directives.

The double insulation symbol shows that the device is protected by dou-

ble 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 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

4 2202V107-UK

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 telling it will switch off the volt-

age to the device.

CALIBRATION AND ADJUSTMENT

During calibration and adjustment, the measuring and connection of external volta-

ges 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 distil-

led water.

LIABILITY

To the extent 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.

HOW TO DISMANTLE SYSTEM 2200

The back panel of the device is detached from the housing by way of a screw-driver

as shown in picture 1.

On a device with knobs, these may have to be removed before the PCB can be

taken out as shown in picture 2.

After this, the back panel can be pulled out together with the PCB, but please

notice the position of the PCB as there is a number of different positions in the

house. Do not pull the wires unnecessarily, instead pull the PCB, see picture 3.

Switches and jumpers can now be moved.

When assembling the back plate and housing, please make sure no wires are stuck.

R/I TRANSMITTER 2202

• Input for Pt100, Ni100 or Ohm

• Sensor cable compensation

• Linearised analogue output

• 24 VDC or universally supplied

• Individual 0 and 100% adjustment

• DIN rail mounting on a standard 11-pole relay socket

Application

Electronic temperature measurement with a Pt100...Pt1000 or a Ni100...Ni1000

sensor. •Conversion of a linear resistance change to a standard analogue cur-

rent / voltage signal from e.g. valves or linear movements with attached poten-

tiometer. • As signal simulator via externally mounted 10-turn potentiometer.

• Suitable in applications with potentiometers that are not fully utilised as the 0

and 100% adjustments on the front can be adjusted individually without interacting.

Technical characteristics

General

The unit is built around a microprocessor core with an efficient program operation.

The supply voltage may be ordered to 24 VDC or with a universal supply of

24...230 VAC and 24...250 VDC with galvanic isolation between supply and input /

output ground. The adjustment range for the 0 and 100% trimmers has a standard

set-up for ±2.5% of span, but the device may be ordered with an adjustment range

of up to ±25%. The sensor connection is always a 3-wire connection with cable

compensation for up to 10 Ωin each wire. If a 2-wire connection is requested pins

7 and 6 must be short-circuited in the socket (no cable compensation).

Input

Pt100 temperature input according to the norm IEC 751 within the range

-200...+850°C. Ni100 temperature input according to the norm DIN 43760 within

the range -50...+250°C. Linear resistance input within the range 0...10 kΩ.

The measurement range should be specified when placing the order, e.g.

0...150°C. The min. span is 50°C for the RTD input; for linear resistance the min.

span is 30 Ω. The RTD input can be delivered as multiples of the main type

(e.g. Pt100 x 10 = Pt1000). The input can be reversed so that 0% e.g. is 150°C

and 100% is 0°C.

2202V107-UK 7

Output

Analogue standard current / voltage output of 0/4...20 mA / 0/2...10 VDC. The out-

put signal is proportional and linear to the value of the temperature or resistance

value that influences the input. Special current or voltage signals can be ordered.

The max. load of the current output is 600 Ω. The minimum load of the voltage

output is 500 kΩ. Also, a number of different sensor error detection methods are

offered, for instance Upscale ≥23 mA.
