General Instructions
IG-258-EN, version 02, 16/11/2018

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.

1. Description and main characteristics
1.1. Definition
The ekor.bat-200 unit is a 24 Vdc or 48 Vdc battery charger,
depending on the model, for connection of units which
feed Ormazabal cubicles.
1.2. Architecture
The ekor.bat-200 charger is a UPS where the battery is
connected to the output, as shown in the image below.

1.3. Processes
1.3.1. Start-up and battery connection
When the unit is connected at 230 Vac, it is energised at this
instant since the unit does not have an on switch.
When the charger is energised, the initial PowerUP process
extracts output voltage and checks that there are batteries
connected; if there are, the internal contact closes, starting
the battery charge process.

General Instructions
ekor.bat-200
Description and main characteristics
1.3.2. Battery charge
Battery charge starts following absence of alternating
current voltage (AC) or after a battery test.
The battery charge process starts with fast charge state.
The charger establishes a voltage setpoint (v_carga) and
controls battery current to ensure it does not exceed
maximum charge current (i_lim). Current is lost as the
battery discharges.
It switches from fast charge state to floating for either of the
following two reasons:
1. The maximum time set for fast charge state (tlim_carga)
is exceeded.
2. The battery current drops below a set threshold (i_flot).
Once the battery current drops below a minimum threshold
(i_flot) or maximum time is exceeded (tlim_carga), it passes
to floating state. In this state the charger establishes the
battery float voltage (v_flot). Following a float time interval
(tmin_flot), it is taken that the battery is completely charged.
The unit remains in floating state until there is an absence of
alternating current or a battery test starts.
The image below shows the typical charge process of a
battery.
In order to extend the working life of the battery, battery
voltage is compensated in accordance with temperature
in floating state. A parametrisable variable (comp_flot)
can be used to adjust the voltage to vary by each degree
centigrade.
The compensation range is limited between a maximum
and minimum temperature (comp_tmin and comp_tmax).
Temperature compensation (hab_comp) can also be
enabled in fast charge state, and there is a voltage variation
setting by degree (comp_carga). Enabling this option is only
recommended when a study indicates that it is required.

1.3.3. Battery discharge and disconnection
In the event of absence of alternating voltage, the batteries
keep the equipment supplied for a specific time interval. A
disconnection process starts if end of battery life is reached
and the alternating voltage input is not restored.
The following operation guidelines are followed in the
disconnection process:
• The unit detects that battery life reaches its end using a
parametrisable setting (desc_v_min)
• The "End of battery life" alarm is enabled at this moment.
• If the AC input is not restored after a few minutes on
standby, the unit disconnects the battery and both the
unit and the connected charges therefore go off.
Apart from the normal discharge process, there are two
other reasons for the battery disconnecting:
• Minimum battery voltage (desc_inm). If it drops below
this threshold, the battery disconnects instantaneously.
• Maximum battery voltage (desc_v_max). If this level is
exceeded, the battery disconnects for safety reasons.

1.3.4. Slow test or capacity measurement
The unit has an automatic mechanism implemented, which
regularly carries out a battery capacity test.
The test consists of:
• The capacity supplied by the battery is measured until:
- The minimum capacity indicated in the standard
(cap_desc) is reached, in which case the test is
passed.
- The maximum time defined for each attempt (tlim_
prueba) is reached, in which case the test is passed.
- The voltage of the battery used to fail the test (v_fin)
drops, in which case:
- If not all the envisaged re-attempts have been
carried out (rein), the battery charges and a test
attempt starts.
- If all attempts have been made, the test is failed and
the "Battery failure" alarm is generated.
Whenever a battery test is failed, the "Battery failure" alarm
is generated and no more battery tests are carried out
until this alarm is recognised. The "Battery failure" alarm is
grouped within the "Urgent failure" digital output.
1.3.5. Fast test or Impedance measurement
The fast test or battery impedance test consists of subjecting
the battery to a specific consumption in order to determine
whether it is still in a good state.
The user can carry out the "battery test" whenever
considered necessary, provided the system is floating or in
constant voltage.
Start-up can be forced using the "Forced battery test"
button in the charger's web. The result of the test is
transmitted immediately to the outside via a potential-free
alarm contact ("Urgent Alarm").
Figure 1.4 shows the response of a battery in poor state.
Figure 1.3. Battery in good state
Figure 1.4. Battery in poor state
In any case, this test is merely to indicate battery state.
If the result is that the battery is in a poor state, repeating
the test after charging for several hours and in floating
state is recommended, in order to ensure the battery was
correctly charged at the moment of the test.

Connections
4.4. Front button (B1)
The ekor.bat-200 charger has a button for the following
actions.
• In total disconnection state. In other words, with charger
off, without alternating voltage input and batteries
connected. If the button is pressed for 5 seconds, the
unit starts up from batteries, provided battery voltage
has an admissible value greater than the minimum
parameterised.
• With the unit running at constant voltage or floating,
the system carries out a battery reconnection in order
to check they are connected whenever the button is
pressed for more than 3 seconds. If there is a battery
connected, the charge process continues and the
battery test failure alarm resets if it is enabled. If there
is no battery, the urgent alarm due to non-connected
battery is enabled.
4.5. Earthing
When installing the equipment, it must be checked that it
is duly earthed. It must be ensured that the charger's two
earth points are duly connected.
Firstly, there is a check by initiation to ensure that earthing
has been carried out correctly in the terminal block. See
section 4.1 for the position of the earth terminal in the
terminal blocks.
It is then confirmed that the earth connection for the chassis
has been carried out correctly. The image below shows the
location of the earth connection.
