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
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
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:
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).
If the device is used with a current transformer, this must be
internally protected against disconnection or mounted with an
alternative external measuring shunt.

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
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,
PR electronics A/S

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
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 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
Picture 1:
The back panel of the device is detached
from the housing by way of a screw-
driver.
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.
Switches and jumpers can now be
moved. When assembling the back
plate and housing, please make sure
no wires are stuck.

TRIP AMPLIFIER 2231
• AC/DC trip amplifier
• 2 adjustable alarm limits
• Galvanically isolated 3.75 kVAC
• Front programmable
• 3-digit LED display
• 24 VDC or universal supply
Applications
Alarm detector in connection with measurement of AC/DC current or voltage
signals. The unit is used where accurate setpoint setting and different alarm
functions are required.
The unit can be used as a single or dual trip amplifier.
Alarm detector can be installed in PELV and SELV circuits.
Technical characteristics
General
The unit is microprocessor-based, which allows a very accurate setting of process
parameters. Each unit is supplied with basic calibration data, which eliminate the
tolerances in the component data. This means that the input can be programmed
to the requested signal range without re-adjustment.
Measurement ranges less than the min. measurement range of 0.5 V down to 10
mV may be entered, though this will affect the resolution and the response time.
Please note that the electric specifications of the device are only kept as long
as the stated min. measurement ranges and max. zero offsets are not exceeded.
Input
Standard DC current signals in the range 0...20 mA.
The current signal is detected by a 50 Ωshunt, which is manually connected
through an internal jumper.
DC voltage signals in the range 0...250 VDC.
By measurement of AC current signals up to 1 A from a current transformer or
current clamp a 1 Ω/ 2 W input shunt is used.
True RMS measurement of AC voltage signals in the range 0...250 VRMS, with a
crest factor < 5.

Functions
The front-operated push buttons are used for programming of the different
standard functions.
Single or dual trip amplifier can be selected. Dual trip amplifier with relay 2 as
pre-setpoint, single or dual trip amplifier with hysteresis in each relay, which is
set as setlow or sethigh and dual trip amplifier with hold on relay 2 until relay 1
is activated.
Make or break function can be selected by an internal jumper.
Programming
The front keys are used for selection of function and for setting all other
parameters like setpoint, reset, active relay for increasing or decreasing signal,
delay, and input signal.
The arrow keys are used as hotkeys if a quick change of setpoint is required.
If the setpoint is changed, the resetpoint follows, so the selected hysteresis is
conserved. A password can prevent access for changing parameters.
Display
During normal operation the 3-digit display shows the input signal in %. All
programmed parameters can be shown by using the front-operated push buttons
(see the routing diagram).
