Europrot+ Maintenance guide_rev1.3en 4/9
1 Introduction
The members of the EuroProt+ protection product line, made by Protecta are designed
basically to require no special maintenance.
In each sampling cycle the device performs self-check in the analog input channels to detect
possible errors as soon as possible.
The periodic revision of the device can improve long-term error-free operation, and if possible,
it supports the required maintenance.
2 Safety precautions
The members of the EuroProt+ protection product line –depending on the type –operate with
dangerous power supply voltage (220 VDC, 230 VAC, 60 VDC, 48 VDC).
In all cases, when the connections of the device are mounted
or the device is opened, the operation should be performed in
all cases by qualified personnel.
In all cases the first step of this kind of operation should be the
disconnection of all power sources.
The internal operating temperature of the devices of the EuroProt+ product line is relatively
high. When contacting the device, immediately after operation, the hot parts can cause
dangerous burning damages.
The activities related to the device may be performed by
qualified personnel only.
The hardware and software of the EuroProt+ protection devices compose a complex system.
Setting, modifying, mounting the individual components may influence the operation of the
whole system.
In all cases, when the device is operated or maintained, the
activities should be performed by qualified personnel only.

3 Hardware maintenance
In order to assure long term, continuous error-free operation, the components with the longest
possible life-time were selected to compose the device.
In case of certain components, e.g. electrolytic capacitors, backlight of the LCD, optical
transmitter-receiver etc., after increased operating time, the availability of the components or
parts may decrease, requiring supervision or replacement as follows.
3.1 Maintenance of the power supply unit
The power supply units are composed of electrolytic capacitors of longest possible life-time.
This expected life-time depends on the environment of the device.
If the device is operated in the range of the permitted temperature limit then in certain time
periods the state of the capacitors is advised to be checked.
During this supervision a qualified expert should check the power supply unit to detect any
deviations of the capacitors, leakage of the electrolytic fluid or considerable loss of
capacitance.
In case of problems, please contact the supplier in the following link:

3.2 Maintenance of the CPU
In the real-time clock of the CPU the actual date and time is running for a certain time even in
disconnected state. The required power is supplied by an EDLC, the expected life time of
which depends on the temperature of the environment.
If the device is operated in the range of the permitted temperature limit then in certain time
periods the state of the capacitors is advised to be checked.
During this supervision, a qualified expert should check the CPU to detect any deviations of
the capacitors, leakage of the electrolytic fluid or considerable loss of capacitance.
In case of problems, please contact the supplier in the following link:

3.3 Maintenance of the display
The operating time of the front panel LCD is about 5000 operating hours. Depending on the
usage of the display, after a certain time the brightness decreases, the readability gets worse.
This functionality is advised to be checked. With normal usage of the display the readability
can be tested.
If the readability of the display does not meet the requirements, please contact the supplier to
perform the exchange of the display.
The supplier can be contacted in the following link:

3.4 Maintenance of the optical data communication
The sender –receiver units of the optical data communication can get weaker, and depending
on the applied components they cannot transmit information with the required power.
Accordingly, in certain time periods the state of this unit is advised to be checked by a
qualified expert or by the manufacturer.
In case of problems, please contact the supplier in the following link:
http://buy.protecta.hu/support/?language=English
3.5 Maintenance of the batteries
The members of the EuroProt+ product line made by Protecta do not contain single-use of
rechargeable batteries.

4 Maintenance of the software
The device can be operated during the lifetime of the device with the software installed by the
manufacturer. No software maintenance is needed.
This chapter lists the software components applied in the device. Also the procedures are
described to achieve the most effective operation of the protection.
4.1 Upgrading the firmware
If the manufacturer detects any critical errors in the applied firmware, then based on the
available device database the users of the device are informed and contacted to coordinate
the needed operations.
Additionally the firmware is continuously developing. If the usage of the latest version is
required then please contact the manufacturer to get information concerning the availability
and need of a new firmware. The link is:

4.2 Upgrading EuroCAP
If the manufacturer detects any critical errors in the applied software, then based on the
available device database the users of the software are informed and contacted to coordinate
the needed operations.
If the user operates several protective devices from one location and some problems are
detected with the application of EuroCAP in case of devices installed recently then please
contact the experts of the manufacturer in the following link:
http://buy.protecta.hu/support/?language=English
Additionally the software is continuously developing. If the usage of the latest version is
required then please contact the manufacturer to get information concerning the availability
and need of a new firmware. The link is:

4.3 Updating the Ethernet browser
The manufacturer does not define preferred browsers. The requirement is the HTML5
compatibility only.
If any problem is detected related to the browser then please contact the manufacturer. The
link is:
http://buy.protecta.hu/support/?language=English
Upgrading the browser is the responsibility of the developer of the browser. Please check the
related product support.

5 Checking and maintenance of the mechanical parts
5.1 Detecting damages
The qualified personnel responsible for the maintenance and operation of the device should
check during any other activities the state of the device for damages, cracking, discolor due to
overheating or high current, or any other disorder.
If any disorder is detected, please act according to the prescriptions of the company, and if
needed, please contact also the manufacturer. The link is:

5.2 Cleaning
No additional external cleaning is needed, only the usual cleaning procedure applied in the
power industry.
If a device is hardly contaminated especially at the human-machine interface then contact the
manufacturer the find the cleaning method to be applied:

5.3 Fastening the screws of the cable connections
The devices of the EuroProt+ product line made by Protecta are equipped with screwed
connectors to connect the cables.
These kinds of connectors do not need any maintenance and fastening the screws.
Accordingly no periodic maintenance or repair is prescribed by the manufacturer.
In order to assure long-term error-free operation it is advised during the cyclic maintenance to
check also the state of the connections.
