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
To keep the safety distances, the relay contacts on the device
must not be connected to both hazardous and non-hazardous
voltages at the same time.
SYSTEM 4000 must be mounted on a DIN rail according to DIN
46277.
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.
HAZARD-
OUS
VOLTAGE
INSTAL-
LATION
GENERAL
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.

4131V104-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 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,
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 indicating that it will switch off the
voltage 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
customer cannot advance a demand against PR electronics A/S that would

CONFIGURATION /
OPERATING THE FUNCTION KEYS
Documentation for routing diagram.
In general
When configuring the 4131, you will be guided through all parameters and you
can choose the settings which fit the application. For each menu there is a
scrolling help text which is automatically shown in line 3 on the display.
Configuration is carried out by use of the 3 function keys:
1 will increase the numerical value or choose the next parameter
2will decrease the numerical value or choose the previous parameter
3will accept the chosen value and proceed to the next menu
When configuration is completed, the display will return to the default state 1.0.
Pressing and holding 3will return to the previous menu or return to the default
state (1.0) without saving the changed values or parameters.
If no key is activated for 1 minute, the display will return to the default state
(1.0) without saving the changed values or parameters.
Further explanations
Fast setpoint adjustment and relay test: These menus allow you to make a
quick setpoint change and relay test when the FastSet menu is activated.
This function can only be activated when the relays are set for setpoint
function and are controlled by a setpoint.
Pressing 1and 2simultaneously will activate a relay test and change the
state of the relay.
Pressing 3will save the setpoint change.
Holding down 3for more than 1 second will return the unit to the default state
without saving the setpoint change.
Password protection: Programming access can be blocked by assigning a
password. The password is saved in the transmitter in order to ensure a high
degree of protection against unauthorised modifications to the configuration.
Default password 2008 allows access to all configuration menus.
