1. Introduction
1.1. This manual
This manual provides basic information on the voltage relay REU 610 and
presents detailed instructions on how to use the human-machine interface
(HMI) of the relay. In addition to the instructive part, a short chapter on
commissioning and maintenance of the relay is included.
1.2. Use of symbols
This publication includes the following icons that point out safety-related
conditions or other important information:
The electrical warning icon indicates the presence of a hazard
which could result in electrical shock.
The warning icon indicates the presence of a hazard which could
result in personal injury.
The caution icon indicates important information or warning
related to the concept discussed in the text. It might indicate the
presence of a hazard which could result in corruption of software
or damage to equipment or property.
The information icon alerts the reader to relevant facts and
conditions.
The tip icon indicates advice on, for example, how to design
your project or how to use a certain function.
Although warning hazards are related to personal injury, it should be
understood that operation of damaged equipment could, under certain
operational conditions, result in degraded process performance leading to
personal injury or death. Therefore, comply fully with all warning and
caution notices.
1.3. Intended audience
This manual is intended for operators, supervisors and administrators to
support normal use of the product.

2. Safety information
Dangerous voltages can occur on the connectors, even though
the auxiliary voltage has been disconnected.
Non-observance can result in death, personal injury or
substantial property damage.
Only a competent electrician is allowed to carry out the electrical
installation.
National and local electrical safety regulations must always be
followed.
The frame of the device has to be carefully grounded.
When the plug-in unit has been detached from the case, do not
touch the inside of the case. The relay case internals may contain
high voltage potential and touching these may cause personal
injury.
The device contains components which are sensitive to
electrostatic discharge. Unnecessary touching of electronic
components must therefore be avoided.
Breaking the sealing tape on the upper handle of the device will
result in loss of guarantee and proper operation will no longer be
insured.

3. Product overview
3.1. Use of the relay
The voltage relay REU 610 is a versatile multifunction protection relay
mainly designed for overvoltage and undervoltage protection and for
supervision of medium voltage distribution networks. The relay can also be
used for protecting generators, motors and transformers.
The relay is based on a microprocessor environment. A self-supervision
system continuously monitors the operation of the relay.
The HMI includes a liquid crystal display (LCD) which makes the local use
of the relay safe and easy.
Local control of the relay via serial communication can be carried out with a
computer connected to the front communication port. Remote control can be
carried out via the rear connector connected to the control and monitoring
system through the serial communication bus.

4.1.2. Display
4.1.2.1. Display test at power up
When connecting the auxiliary voltage to the relay:
1. The backlight is turned on after the relay has performed the internal
power-up tests and entered into the protection mode.
2. The display is tested by inverting it for approximately three seconds, see
Fig. 4.1.2.1.-1.
3. The display is returned to the idle mode and the backlight is turned off if
no operation target message is displayed. However, if the non-volatile
function is active, a message shown on the display before the auxiliary
voltage was disconnected reappears on the display.

4.1.6. HMI password
The HMI password protects all user-changeable values on the technical level
from being changed by an unauthorized person. The password function
remains inactive until the default password is replaced. The default HMI
password is 999. You can also change the password from a remote unit via
parameter V162, but you can only read the password via the HMI.
As soon as you have replaced the default HMI password, the new password is
required for altering parameter values. Once you have given the valid
password, the display remains in the setting mode until returned to the idle
mode.
