OVERVIEW
1.2.1.
INTRODUCTION TO F650 AND F600 FAMILY OF RELAYS
This platform of relays has been designed to meet the goals that are appearing nowadays in the environment of new
substations. Historically, protection, control and metering functions have been performed by electromechanical
elements at the beginning, then static devices, and finally by digital equipment able to integrate all these functions in
a single device, called IED (Intelligent Electronic Device).
Due to the huge number of signals to be controlled and monitored nowadays in a substation environment, there is a
new need for a great number of digital inputs and outputs to retrieve states and to signal or perform all different
operations. CIO units respond to this need, allowing connection to F650 and F600 IEDs, and increasing the number
of available inputs and outputs depending on the connected equipment.
1.2.2.
HARDWARE ARCHITECTURE
CIO units incorporate a series of interconnected modules to operate. These modules are a power supply and
input/output boards.
CIO
Contact Inputs
Contact Outputs
FIGURE 1-3 HARDWARE ARCHITECTURE
As shown on the diagram above, Contact Inputs/Outputs are signals associated to physical input/output contacts in
the relay, and their status is sent/received through the CAN BUS of the associated equipment, F600 or F650.
This CAN connection to the master unit can be made through fiber optic cable or through copper cable.
CIO units can incorporate up to two I/O boards, each of which must have a unique address in the system. For this
purpose, there is a switch at the rear of the unit with 16 positions (0 to F), that allows indicating the address for board
H. The address of board J is fixed to “board H address + 1”.
1.2.3.
SOFTWARE ARCHITECTURE
Each I/O board includes a microprocessor that manages communication with the master unit, as well as sampling
and activation of the corresponding inputs and outputs.
The firmware (software embedded in the boards) has been designed using object oriented programming techniques
(ODD/OOP). These techniques are based on the use of objects and classes, and provide the software architecture
with the same characteristics as the hardware architecture, i.e., modularity and flexibility.

OVERVIEW
1.2.4.
COMMUNICATIONS ARCHITECTURE
CIO units incorporate a CAN BUS port in two physical media: glass fiber optic and cable. The fiber optic port allows
connection to the master unit for a single CIO unit. For connections including several CIO units, the cable port must
be used. If the master unit is a F650, then communication must always be in fiber optic.

2.1.
OVERVIEW
The CIO module is an input/output extension for F650 and F600 units. Using this module, the number of available
inputs/outputs can be increased, these inputs/outputs operation being identical to the one of the original I/Os in
the master unit.
The CIO module has been designed to be installed close to the substation switchgear, and connected to the main
unit through a CAN bus in fiber optic or cable. Fiber optic connection provides total immunity against
electromagnetic disturbances, as well as simplified wiring and commissioning.
CIO module I/O configuration and management are performed exclusively from the master unit. This master unit
manages the CIO inputs and outputs in the same way as its own.

FIGURE 3-1 BLOCK DIAGRAM
F650 units incorporate the following modules:
Power supply
Input/Output module
Optionally, a second I/O module can be added.
A relay connected to the low voltage side of the power supply monitors this voltage. The three contact terminals,
normally open, common, and normally closed, are available at the external connector terminals. This relay monitors
only the power supply integrity.
This is a “fly-back” type power supply, providing high efficiency, stability and reliability thanks to the maturity of this
technology. There are two available ranges, Hi and Low, in order to optimize efficiency and general performance,
including the capability to tolerate auxiliary voltage interruptions (dips).
Oversized components highly resistant to temperature are used. For example, all capacitors are specified to stand up
to 105ºC, transformer components are specially designed to stand up to 180ºC, the used MOSFET transistor is of
very low resistance, supports high voltage and is refrigerated by an oversized heat sink. This allows supporting
extremely high temperatures, and prolonged overloads such as the ones occurring at batteries in deep charge mode
(much higher than the maximum voltage shown in the Technical Characteristics section).
High capacity capacitors are also used, providing high tolerance to prolonged dips, 100ms, even in the most
unfavorable consumption conditions. This allows the relay to continue with normal operation without undesired resets,
which would cause a long time of protection unavailability

MECHANICAL DESCRIPTION
The model number and electrical characteristics of the unit are indicated on the label located on the right side of the
relay case.
The metallic case of the unit is highly resistant to corrosion. It is made of stainless steel (AISI 304), coated with an
epoxy layer, and the rest of the metallic pieces are covered with a high quality resistive coating that has successfully
passed at least 96 hours in the salt spray chamber (S/N ASTM B-117).
The front of the relay is made of a conductor thermoplastic, flame retardant (V0), highly resistive material, which
guarantees the unit’s immunity to all kinds of EMI/RFI/ESD interferences. As well, an IP51 (IEC 529) protection
degree against dust and water through the front and with the relay mounted in the panel.
In order to guarantee safety and preventing access to the unit by unauthorized personnel, the front communications
port and the operation mode key are protected by a sealable cover.
3.2.1.
MOUNTING
The unit is designed for both semi-flush mounting with the terminals on the back, and rear panel mounting, with the
terminals towards the front. In both cases the relay should be secured to the panel with the M6 screws provided with
the unit.

BOARD OPTION 2
Option 2 I/O board includes two groups of 4 inputs with one common, in terminals 9 to 10. It also includes 6 auxiliary
outputs, in terminals 19 to 30 with normally open contacts and two current sensing (latching) outputs.
Besides, there are 2 groups of inputs for trip circuit supervision. The first group includes two isolated digital inputs,
terminals 1-2 and 3-4. The second group, symmetrical and identical to the first, is formed by isolated voltage inputs
15-16 and 17-18.
Inputs in both groups are wet contacts, this means they need to receive a positive in the terminal labeled as + coming
from a power supply whose negative is connected to the terminal labelled as -.
Using voltage detectors and current sensing, it is possible to implement several trip or close circuit supervision
schemes, as well as protection of the unit output contact.
In order to implement these schemes, it is not necessary to perform any setting in the unit. Internal functions are
always operative and provide the following logic operands:

(SUP_COIL2)
A continuity failure is detected in a circuit when both voltage detectors (Va and Vb) detect lack of voltage during more
than 500 ms. This function is not influenced by the breaker status.
These operands can be associated to internal signals (virtual outputs), LEDs or unit outputs, to issue alarm signals or
to block elements, for example for blocking the Breaker close if an abnormality is detected in the trip circuit.
Available schemes are as follows:
1. Without supervision
2. With current supervision (with seal-in)
3. With simple voltage supervision
4. With double voltage supervision
5. With current and simple voltage supervision (with seal-in)
6. With current and double voltage supervision (with seal-in)

HARDWARE
The following lines describe the different types of connection to create each scheme in an easy way. As the
supervision circuits are identical, we will describe connection examples for the first group. They are also applicable to
the second group.
The symmetrical location of digital inputs is an optimization for ensuring a high isolation between groups that,
belonging to different groups could be connected to separate batteries, and therefore a greater distance between
circuits is required.
3.4.2.1. WITHOUT SUPERVISION
This is a very frequent case, and we must only wire the tripping circuit to terminals 35 and 36, leaving unused
terminals 34, 15, 16, 17, 18.

HARDWARE
3.4.2.2. WITH CURRENT SUPERVISION (WITH SEAL-IN)
In this case, as shown on FIGURE 3-9, the current supervision circuit consists in a circuit connected in series with the
output contact, so that the external circuit is wired to terminals 34 and 36. This supervision circuit includes a low
impedance reed relay that is activated when the current value exceeds 100 mA, and sends a signal to the main
microprocessor. This indication can be used to produce a latching of the output relay, so that it will remain closed
while the circulating current is over 100 mA. For this purpose we don’t need to program any setting, it is enough to
wire it as shown on FIGURE 3-9.
With this scheme, in the case of a failure to open from the breaker auxiliary contact, the CIO output relay will not be
the one to open the tripping coil current, as in this case the contact may result damaged, as it is prepared for opening
currents around 0.5 A at 125 Vdc.
This latching or memory function is only guaranteed while the unit is powered.

TRIP with 52 open
There is a possibility to monitor the trip circuit and trip coil continuity. This can be done by monitoring Vdc through the
output contact when this is open.
As shown on FIGURE 3-10, when the relay is not tripped, trip contact 35-36 remains open. If the breaker is closed, its
auxiliary contact 52a is closed. Therefore, a little current is flowing, about 2 mA, through terminals 15 and 16 through
the voltage detector circuit, which flows through 52/a and the tripping coil 52TC (TC = tripping coil). Current will only
circulate when there is continuity in the whole circuit, so the complete circuit is monitored, and not only the trip coil.
This circuit includes auxiliary 52/a as well as the whole wiring between the battery and the relay tripping terminals,
and between these and the breaker tripping circuit.
This is the first case shown on the table. With closed breaker, voltage is detected by V 52/a sensor, and this means
that there is continuity in the supervised circuit.
In this table, ON means that the voltage detector V52/a is active, detecting voltage presence.

HARDWARE
For the second case shown on the table, open breaker, its auxiliary contact 52/a remains open, and current cannot
flow through it for detecting continuity. In order to correctly monitor the circuit, a resistor must be used, not included in
the protection, connected in parallel. The value of resistance will be selected so that the V 52/a input circuit minimum
detection current flows, but not as high as to activate the breaker tripping coil. The figure shows the following
equation:
V min – 15
R = -------------------
2
Where:
Vmin
Is the minimum voltage, in Volts, expected in the battery (e.g. 80% of Vn)
Resistance, in kilo ohms.
R
2
2 mA of approximate current flowing through input V 52/a
As shown in the second case in the table, with an open breaker, as current will flow through R if there is continuity in
the WHOLE tripping circuit, voltage will be detected in input V 52/a.
This works correctly in steady state. However, if the breaker trips, while it is opening, the V 52/a input signal can be
deactivated without this meaning that the circuit is not correct. This is due to the fact that the tripping relay, terminals
35-36, short circuits input V 52/a temporarily.
Therefore, if there is a trip signal, it is admitted that no signal will be detected during a period of 1 s to allow the
breaker to open, and reopen the tripping relay 35-36.
FIGURE 3-11 shows the possibility of monitoring the circuit only when the breaker is closed. In this case resistance R
will not be used, but it must be observed in the unit logic, that the corresponding signal CONTACT INPUT_00_15
(SUP_COIL2), will be activated showing a failure when the breaker is open, and therefore it will be required to
supervise the continuity failure signalling by the breaker status information.

There is a possibility to monitor the trip circuit continuity not only via its auxiliary contact 52/a, but also with auxiliary
contact 52/b. This avoids the need to install a resistance in parallel with auxiliary 52/a. The correct connection is
shown on FIGURE 3-12.
The circuit works in a similar way to the one described in the previous section, but it uses both supervision inputs 15-
16 and 17-18.
The advantage in this case is that circuit supervision with 52 open is more complete, as input V 52/b is used through
contact 52/b, (that is closed when the breaker is open).
We must point out that in this scheme, the tripping contact, shown in the example as the CIO trip relay, can be the
one in the relay (terminals 35 and 36), or be provided by another protection or by the parallel of several protections.
This provides high flexibility in the use of this circuit.
The battery voltage can also be monitored, by using one of the standard digital inputs.

SOFTWARE
CIO units need to be connected to a master unit, either an F650 or an F600. If the master unit is an F650, the CIO
can be programmed using EnerVista F650Setup program; in case of using an F600 as master unit, the CIO can be
programmed using GE-CONF software. In both cases, CIO inputs/outputs will be shown as if they were part of the
master unit, with the same programming options as the master unit I/O.
EnerVista F650Setup software provides a simple way to configure, monitor and maintain operation of F650 and the
connected CIO unit. Please refer to the F650 user manual for a more detailed reference about EnerVista F650Setup.
In the same way, please refer to GE-CONF software manual for details about programming a CIO unit connected to
an F600 master unit.

CIRCUIT SUPERVISION AND CONTACT SEAL-IN CIRCUITS
5.1.1.
CIRCUIT SUPERVISION
CIO units can include type 2 boards. This type of board includes 4 voltage detectors for implementing tripping or
opening circuit supervision control logics.
5.1.2.
CONTACT SEAL-IN
The current seal-in circuit is used for verifying the current condition in a circuit during the time that the tripping contact
remains closed. If the current in the tripping circuit is maintained over 100 mA, the function is sealed independently of
the status of the function that caused the trip.
This current seal-in function in tripping circuits is mainly used in applications where auxiliary contacts 52/a (in charge
of cutting the current in the tripping circuit) are very slow. This may cause that, once the function that produced the
trip is reset, the relay contact will open before the breaker auxiliary 52/a, even if the time delay of the first has expired.
By using this function, we prevent the relay contact from cutting the current (basically inductive and high) from the
tripping circuit, which could cause damage to the unit, as these currents exceed the nominal breaking characteristics.
The circuit and the current threshold of the function are as follows:

I/O MODULES DESCRIPTION
Settings relative to Inputs:
Input Activation Voltage Threshold: This value can be from 0 to 255 volts. There is a single setting for all inputs in
the same group (inputs sharing the same common). In mixed and supervision boards there are two groups of inputs,
called A and B.
Debounce Time: This is the debounce time set for inputs (1 to 50 ms). The debounce time is the time window for
input filtering. If an input suffers a change of level that lasts less than this set time, the change will not be considered.
There is a single setting for all inputs in the same group.
Delay Input Time: This is the delay applied to the input signal; the default value is zero, meaning no delay; the
setting range is 0 to 60000 milliseconds (1 minute). This setting is used in slow switchgear applications.
This is not a grouped setting; there is a different setting for each input. It is important not to confuse this delay input
time with the debounce time used for filtering undesired transients in the input signal. The Debounce time is always
added to the delay input time.
Input Type: Type of logic associated to the physical input. Possible settings are, positive and negative.
Positive and Negative settings correspond to signals that are activated or deactivated with the input level, considering
the delay setting. Positive-edge, and Negative-edge settings correspond to signals that are activated with the change
of the input signal; in this case, the Delay Input Time will not be considered, only the Debounce Time; this edge
signals are deactivated automatically after one PLC scan cycle. FIGURE 5-2 shows the types of signals associated to
the different input configuration types.

Settings relative to Outputs:
Output Logic_0X _XX: Type of logic applied to outputs. Possible values are positive and negative. The default
value is positive.
Output Type_0X _XX: Type of output adjusted. Possible values are normal, latched or pulse; the default value is
Normal.
Pulse Output Time_0X _XX: This is the output pulse length in case the output type is selected to be pulse; the
default value is 10000 ms.
Output Logic: Type of logic applied to outputs; possible values are Positive and Negative; the default value is
Positive. Depending on the type of setting selected, the physical output will be in the same direction (positive) or
opposite (negative) the output activation command.
Output Type: This is the set output type. Possible values are normal, latched or pulse; the default value is Normal.
Normal type follows the activation command. Pulse type delays the time, according the Pulse Output Time setting.
Latched type remains active after the activation command. The physical output reset when it is configured as latched
can be performed using a deactivation command. Such command must be configured at Setpoint > Relay
Configuration > Outputs > Contact Output Reset”.
Pulse Output Time: This is the output pulse length, applicable only to signals set as pulse type; the default value is
10000 ms and the setting range is 0 to 60000 ms (1 minute).

6.1.
VISUAL INSPECTION
Verify that the relay has not suffered any damage during transportation, and that all screws are correctly fixed, and all
relay terminal boards are in good condition.
6.2.
GENERAL CONSIDERATIONS ON THE POWER SUPPLY NETWORK
All devices running on AC current are affected by frequency. As a non-senoidal wave is the result of a fundamental
wave plus a series of harmonics from this fundamental wave, it can be deducted that devices running on AC current
are influenced by the applied waveform.
For a correct testing of devices running on AC current, it is fundamental to use a current and/or voltage senoidal
waveform. The pureness of a senoidal wave (lack of harmonics) cannot be expressed specifically for a specific
device. However, any relay incorporating sintonized circuits, R-L and R-C circuits, will be affected by non-senoidal
waveforms.
These devices respond to the voltage waveform in a different way to the majority of AC current voltmeters. If the
power supply network used for the testing contains wide harmonics, the voltmeter and relay responses will be
different.
When the device is tested, a power supply network with no harmonics in its waveform must be used.
It is important to point out that the accuracy with which the test is performed depends on the network and on the
instruments used. Functional tests performed with unsuitable power supply network and instruments are useful to
check that the device operates properly and therefore its operating characteristics are verified in an approximate
manner.
The following sections detail the list of tests for verifying the device functionality.

ISOLATION TESTS
During all tests, the screw located on the rear of the relay must be grounded.
For verifying isolation, independent groups will be created, and voltage will be applied as follows:
2000 RMS volts will be applied progressively among all terminals in a group, short-circuited between them
and the case, during one second.
2000 RMS volts will be applied progressively between groups, during one second.
WARNING: No communication circuit shall be tested for isolation.
Groups to be created will depend on the type of modules included in the CIO, selectable according to the model.
The following table shows the different groups depending on the module type:
