General instructions
IG-150-EN, version 04, 03/10/16

In view of the constant evolution in standards and design, the characteristics of the elements contained in this manual are subject
to change without prior notice. These characteristics, as well as the availability of components, are subject to confirmation
byOrmazabal.
CAUTION!
When medium-voltage equipment is operating, certain components are live, other parts may be in movement and some may
reach high temperatures. Therefore, the use of this equipment poses electrical, mechanical and thermal risks.
In order to ensure an acceptable level of protection for people and property, and in compliance with applicable environmental
recommendations, Ormazabal designs and manufactures its products according to the principle of integrated safety, based on
the following criteria:
• Elimination of hazards wherever possible.
• Where elimination of hazards is neither technically nor economically feasible, appropriate protection functions are
incorporated in the equipment.
• Communication about remaining risks to facilitate the design of operating procedures which prevent such risks,
training for the personnel in charge of the equipment, and the use of suitable personal protective equipment.
• Use of recyclable materials and establishment of procedures for the disposal of equipment and components so
that once the end of their service lives is reached, they are duly processed in accordance, as far as possible, with the
environmental restrictions established by the competent authorities
Consequently, the equipment to which the present manual refers complies with the requirements of section 11.2 of Standard
IEC 62271-1. It must therefore only be operated by appropriately qualified and supervised personnel, in accordance with the
requirements of standard EN50110-1 on the safety of electrical installations and standard EN50110-2 on activities in or near
electrical installations. Personnel must be fully familiar with the instructions and warnings contained in this manual and in other
recommendations of a more general nature which are applicable to the situation according to current legislation[1].
The above must be carefully observed, as the correct and safe operation of this equipment depends not only on its design but also
on general circumstances which are in general beyond the control and responsibility of the manufacturer. More specifically:
• The equipment must be handled and transported appropriately from the factory to the place of installation.
• All intermediate storage should occur in conditions which do not alter or damage the characteristics of the equipment
or its essential components.
• Service conditions must be compatible with the equipment rating.
• The equipment must be operated strictly in accordance with the instructions given in the manual, and the applicable
operating and safety principles must be clearly understood.
• Maintenance should be performed properly, taking into account the actual service and environmental conditions in
the place of installation.
The manufacturer declines all liability for any significant indirect damages resulting from violation of the guarantee, under any
jurisdiction, including loss of income, stoppages and costs resulting from repair or replacement of parts.
Warranty
The manufacturer guarantees this product against any defect in materials and operation during the contractual period. In the
event that defects are detected, the manufacturer may opt either to repair or replace the equipment. Improper handling of this
equipment and its repair by the user shall constitute a violation of the guarantee.
Registered Trademarks and Copyrights
All registered trademarks cited in this document are the property of their respective owners. The intellectual property of this manual
belongs to Ormazabal.

337/2014 is obligatory.

1. General description
The ekor.rps units are multifunctional protection relays
of numerical technology, and they constitute the basic
element of protection, measurement and control for
cogeneration facilities or for HV/MV electrical bays. They
can be used as autonomous elements of protection, control
and measurement of an electric bay, or integrated within an
integrated protection and control system.
Inside the family dierent models exist that dier to each
other for some hardware aspect or for their functionality.
The Firmware is common for all the models; the available
functions for the user in each model are dened in a circuit
of programmable logic (PLD). The Firmware is chargeable in
the equipment through the serial port, what facilitates the
versions updating.
1.1. Scope of the manual
This manual does not t a certain ekor.rps model, it ts the
whole options (for FW version equal or newer than W). For
each specic model only the physical characteristics and
functions of the model are applied. The manual consists of
two volumes: The rst contains the information regarding
conguration, functions etc. and the second contains the
following appendixes: Curves for the operation of the timed
functions,communicationprotocols,keyboard/displaymenu
structure, etc.
Anyway,eachunitisprovidedwitharesumed“characteristics
sheet”, which describes the functions of the specic model
and its interconnections diagram.

For models with two communication ports,
COM 2 port protocol is programmable, and
COM 1 protocol is always PROCOME.
79 (81 m) (recloser by underfrequency) unit,
only exist for models with 81 U
For the models marked with an * in the
transformer arrangement table
Only for models with 67 N and T9 = Ip
(*olarization current)
With “T” type box, the communication must
be“T”
In this case, the Ethernet port protocol is
encapsulated PROCOME

1.4. User interface
1.4.1. Local
The front board has:
1. 16 key keyboard
2. 4 signaled push-buttons
a. : Breaker closure
b. : Breaker opening
c. : Local/remote
d. :It validates the other three pushbuttons, to avoid
unwished maneuvers. It must be pushed at the same time
you push the other buttons for them to have effect
These pushbuttons must be pushed at least for 0.5 s to be
considered active.
Moreover, the pushbuttons to be eective, “push-
button enable” setting must be set as “YES” (see “other
conguration settings”chapter).
3. 2 line, 16 character LCD
4. 7 red LEDS and one green/red
5. RS232 connector for direct connection with a PC.
PROCOME protocol
1.4.2. Remote
Depending on model the rear board has one or two ports
which can be glass ber optic (ST type connector), plastic
ber optic, RS232 or RS485 for connection to PC, modem or
substation control unit (in integrated systems).The protocol
can be PROCOME, DNP 3.0, MODBUS or IEC 870-5-101 or
IEC870-5-103.
There are also models with one Ethernet port (ber optic or
RJ45), with PROCOME TCP/IP protocol.

directional inputs (with polarity).
f. Restricted 220 Vdc: 165 up to 264 Vdc. They are single-
directional inputs (with polarity).
5. Number of digital inputs/outputs:
a. Standard:
8 inputs (5 independent, 3 with a common point).
7 outputs (4 independent, 3 with a common point).
b. Extended: Adds to the standard:
9 inputs (6 independent, 3 with a common point).
7 outputs (4 independent, 3 with a common point).
c. Extended (option 2): adds to the standard:
5 independent inputs.
6 outputs (4 independent, 2 with a common point).
2 analog outputs (0 to 5 mA); for other ranges please
consult Ormazabal’s technical–commercial department.
6. Rear communication:

In case of having two rear ports, the one mentioned in second
place is in parallel with the front RS232 (they occupy the same
port).
7. Analogue inputs:
The unit can have up to 9 analog inputs (through
transformer).– Preferential option.
Inputs 1, 2 and 3 are used for phase currents measurement.
Input 4 is used for neutral current measurement.
Input 5 depends on model. There are the next possibilities:
a. No input
b. Sensitive neutral or isolated neutral current
measurement
c. Zero sequence voltage measurement V0
Inputs 6,7 and8 areused for thephase voltagesmeasurement.
Input 9 depends on model. There are the next possibilities:
a. No input
b. Zero sequence voltage measurement V0for the
Syncrocheck function

1.9. Wiring diagrams
All the following wiring diagrams show one of the possible
digital input and output programming (very simple). See
all the possibilities in “programming of digital inputs” and
“programming of digital outputs”sections.
In the outputs with change-over contact the common point
is the middle one.
