General

The Eaton arc flash relay 101C (EAFR-101C) is a sophisticated microprocessor- based arc flash protection relay including complete self-supervision functionality. It is designed to minimize the damage caused by an arcing fault (arc flash) by sensing light from the point sensor and acting to trip the circuit breaker sourcing the fault current. The EAFR-101C complete system self-supervision function provides the highest level of dependability by continuously monitoring all internal system functions along with external connections. The EAFR-101C is designed according to the latest protection relay standards and is therefore suitable for installations in rough environments, such as utility, traditional or renewable power plants, offshore, marine, oil and gas, mining, steel, or any other heavy industry applications. It is also well suited for commercial and institutional electrical systems. The EAFR-101C is suitable for either medium voltage or low voltage switchgear and motor control center applications in both new and retrofit installations.

EAFR-101C features

The EAFR-101C is a multipurpose arc flash protection relay that can receive light from four different channels of light point sensors and can be applied for a variety of applications. The EAFR-101C can be used as a stand-alone relay or as part of a more complex arc protection system through the binary bus.

Main features of EAFR-101C

• (110-220) Vac / (125-250) Vdc auxiliary power supply;
• (18-72) Vdc optional power supply;

Simplified block diagram

The EAFR-101C simplified block diagram (see Figure 2) shows the main components of the EAFR-101C relay.

Operation and configuration

LED indicator functions
The EAFR-101C contains 16 indication LEDs. A user-definable text pocket can be slid in under the label for identifying each LED function (except POWER and ERROR LEDs). LEDs are located at the front plate of the relay for clear viewing without a need for opening doors. During power-up, the relay performs an LED test. All LEDs are turned on for two seconds and then off. Only the blue POWER LED will remain on. After powering up, the relay goes into protection mode in 50 ms even while the LED test is being performed. During normal operation, the blue power LED is ON, as are any CB open/close status LEDs for connected CBS. The sensor LEDs are off during the inactive condition. If a point arc sensor is activated, the corresponding sensor channel LED will turn on if the activation is longer than 1.5 ms. The sensor LED activation function is latched (steady light). To clear the LED, the “SET” button should be pressed.

In case of a loose sensor wire and binary input wires or configuration mismatch (new sensor attached without running auto-configuration system setup (see Section 3.3.1) situation, the corresponding LED for that sensor will start flashing and the ERROR LED will activate.
The Binary I/O LEDs indicate the I/O-line status. If any of the lines become active for more than 1.5 ms, the corresponding LED will turn on (latch).
In a trip situation, the corresponding trip LED will turn on. Trip outputs are controlled by the dipswitch settings (see Section 3.5). All activation and trip indication LEDs are latched, even if the dipswitch setting is in the non- latched mode. They have to be cleared by pushing the “SET” button. LED indications are stored in non-volatile EPROM memory for identifying the trip information in case the auxiliary power is lost. When re-powering the relay after power supply loss, the actual LED status can be visualized from the front of the relay.

Push-button description

The EAFR-101C contains one single push-button (SET) that can be used for all operational functions of the relay. The push-button is used to initialize the auto-configuration of the system (see Section 3.3.1) and for resetting the indicators and latched output relays.

Autoconfiguration (System setup)

When all sensors and binary lines have been connected, an
the auto-configuration procedure must be executed. The initialization sequence is performed by pressing the “Set” button for two seconds. The EAFR-101C sensor LEDs and all binary LEDs start blinking. The relay scans these inputs to see if they are connected and when an input is detected, the corresponding LEDs are illuminated to mark that a connection was found. The inputs without connection continue blinking during the remaining three seconds. After five seconds, all LEDs are turned off. During this system setup, the dipswitch setting are also stored in non-volatile memory. All sensor inputs will remain operational even when they are not auto-configured. The auto-configuration is only used for self-supervision purposes. Note: To redo auto-configuration for a relay containing fewer connections (binary inputs/outputs or sensors) than in a previously memorized set-up, a dipswitch (anyone) must be moved back and forth prior to performing- ing auto-configuration. The timeout allowing a new configuration is one minute. Reconfiguration with more connections is allowed without moving a dipswitch.

Reset

All LED indications and latched trip relays are reset by pressing the “SET” button for one second. Otherwise, the latched trip relays will remain activated until auxiliary power is disconnected. All LED indications will remain active until reset is performed by the operator, even when the auxiliary power supply is disconnected (see Section 3.6: Non-volatile memory).

Dipswitch settings

EAFR-101C functionality, such as tripping logic, is configured using dipswitch settings. Different trip configurations can be easily programmed by selecting the appropriate dip switch positions. This gives users the flexibility to change settings depending on the application. Tripping may be selected based on arc light only or arc light and current thresholds. Current threshold or other tripping criteria may be applied to binary input BI1 for blocking a trip caused by natural light sources. Dipswitches 1 and 2 are used as configuration selection. Dipswitch 3 is for configuring BI5 to operate as a Master Trip input or as a current information input. Dipswitch 4 and 5 are for setting binary input pairs 1-2 and 3-4 as active or inactive. If a circuit breaker is connected to a binary input pair, the respective dip switch should be set to ON. Dipswitch 6 sets whether trip relay outputs T1 and T2 latch or activate momentarily. Dipswitches 7 and 8 set whether sensor channels 1/2 and 3/4, respectively, pick up on light only or on light and current. Dipswitches are located at the back of the relay for easy access (see Figure 3: EAFR-101C Dipswitch SW1 and Table 2: EAFR-101C dipswitch setting selection for details of settings).

Arc sensors

The EAFR series provides the choice of different types of arc sensors to be utilized in different units and different switchgear types, according to the specific application requirements. Available sensor types are arc light point sensors and arc light fiber optic loop sensors. Arclight point sensors are typically installed in metal-enclosed compartments, providing quick accurate location of the faulted area. Arclight fiber loop sensors are installed typically to cover a wider protected area with one fiber when no need for a more exact fault location exists. The EAFR-101C only accepts light point sensors.

Arclight point sensor EAFR-01

The EAFR-01 is an arc light point sensor with a light-sensitive photo-diode element activated by receiving arc light. The EAFR-01 arc sensors should be mounted in the switchgear cubicles in such a way that the light sensitive part can receive light from the protected area.
The fixed light sensitivity of the EAFR-01-A sensor is 8,000 Lux. The sensor does not require any user settings. The point sensor’s light detection radius is 180 degrees. Other point sensors are available with different Lux sensitivities: EAFR-01-B at 25,000 Lux and EAFR-01-C at 50,000 Lux.

installation and wiring

The EAFR-01 point sensor can be installed either on or through the compartment wall. An example of on-the-wall mounting is seen in Figure 55. The EAFR-01 is fixed against the wall using two screws. The same screw pattern is utilized in a through-wall mounting arrangement. In this arrangement, the unit is turned around and the point of the eye of the photodiode sensor protrudes through a small hole cut in the wall. The point of the sensor now faces the compartment to be protected. This allows for the body of the sensor and cabling to be located outside the compartment. For both types
of installation, two screws are attached from the backside of the sensor. No external mounting plates are needed.
The EAFR-01 cable connectors are located beneath the covers that can be conveniently detached for fastening the sensor wires. The cover will be attached after installing the wires. The cable connec-tors are located at both ends of the sensor for a series connecting a maximum of three sensors in one line.

point sensors technical data

System self-supervision

The EAFR-101C includes an extensive self-supervision feature. Self-supervision includes both internal functions and external connections. The self- supervision module monitors power supply, hardware, and software malfunctions, and binary input connection and sensor problems. Dipswitch settings are also supervised by comparing the actual value with stored non-volatile memory data (see Section 3.3.1: Auto configuration [System setup]). In a healthy condition, the POWER LED is on and the System Failure (SF) relay is energized. If the self-supervision function detects a faulty condition or the power supply fails, the self-supervision relay is released and the ERROR LED is illuminated. If a sensor failure occurs, the relay will go into ERROR mode. The ERROR LED will illuminate, the SF relay will release, and the corresponding faulty SENSOR CHANNEL LED will start blinking. In this situation, the relay is still in the protection mode, but with the faulty sensor, the channel is blocked. If the error is resolved, the ERROR LED will automatically clear the SF-status and failed SENSOR CHANNEL LED will remain in blinking status. This means that the SF relay will energize and the ERROR LED will turn off. If one or more of the sensors are disconnected, the healthy sensors remain in use, and the relay remains operational. The EAFR-101C will remain in error mode until the disconnected sensors are repaired. If a dipswitch setting is changed after the auto-configuration function (see Section 3.3.1: Autoconfiguration [System setup]) has been executed, the relay will go into SF alarm mode. The configured (stored) the setting is however still valid and the relay is still operational.

Application examples

The EAFR-101C may be applied to a variety of power switchgear layouts. Please refer to IB0191003EN, manual for standard arc configurations in low voltage switchgear.

CONNECTIONS

Outputs

The EAFR-101C relay has integrated trip relays T1 and T2 for tripping of the circuit-breakers. T1 and T2 relays are normally open types (NO) relays.
Trip relay T3 is a (NO) trip relay that operates anytime the T1 or T2 relay operates and can be used either for tripping one more disconnecting device or for a trip alarm to local or remote monitoring and alarming system.

Binary output BO1, and BO2

Two binary outputs are available (+ 24 Vdc). BO1 is the light signal output to connected EAFR-110PLV relays. This output activates when light is received on one of the light sensor inputs. BO1
also transmits a health pulse back to the EAFR-110PLV relay that
is specific to the serial number of the relay. This health pulse is interpreted by the EAFR-110PLV as an indication of a good connection with the 101C relay. BO2 is the Block Out signal. This output activates when either of the connected circuit breakers opens. This sends the blocking signal to all other connected EAFR-101C relays. For more information on the blocking signal, see Section 7.2.2 Circuit breaker binary inputs BI1, BI2, BI3, and BI4.
Note: The binary output is polarity sensitive (see IB0191003EN

System failure (SF) relay

The SF relay is a form C type (NO/NC) and is energized in a healthy condition. Whenever the EAFR-101C detects a system error or disconnection of the auxiliary power supply, the contact changes its state. The state of the SF relay remains the same until the EAFR-101C returns to a healthy condition and the SF relay is again energized.

Inputs

The EAFR-101C has four arc point sensor channels. A maximum of three arc point sensors (type EAFR-01) may be connected to each channel.
For details on sensors refer to Section 4: Arc sensors.

Circuit breaker binary inputs BI1, BI2, BI3, and BI4

The EAFR-101C contains six binary inputs. The inputs are activated by connecting a dc signal exceeding the specified nominal threshold level of the corresponding input. The nominal threshold level is 24 Vdc. The actual activation of the binary input occurs at 80% of the specified nominal threshold value (i.e. 16 Vdc). BI1 and BI2 are reserved for the breaker open/close status informa-tion. When an air-insulated circuit breaker interrupts a fault, a high current is present, as is light from the arc chutes on the circuit breaker, and the EAFR system may operate as if this event were an arc flash. If the CB has outputs that give an indication of an opening operation before the primary contacts part, these outputs can be connected to BI1 + BI2 or BI3 + BI4. If an input is received on either of these two input pairs, the EAFR-101C restrains sending any light information out on BO1 for 50 ms. This gives the circuit breaker a long enough time to clear the fault. Also at the time of input, the EAFR-101C outputs a blocking signal on BO2 to all other connected EAFR-101C relays. This communicates to the other relays in the system to also restrain passing light information out for 50 ms. After 50 ms, if any light is still present, the EAFR-101C will then give a light-out signal on BO1. This blocking operation only occurs when a connected circuit breaker opens. A normally open (Form a) and normally closed (Form b) output is required from each connected circuit. This is for signal redundancy and error checking. If the input is the same on BI1 and BI2, or on BI3 and BI4, the self-supervision relay is released and the ERROR LED is illuminated. The corresponding LEDs for the circuit breaker input will blink synchronously on the front of the EAFR-101C. If a circuit breaker will be taken out of service for an extended period, it is advisable that the input for that circuit breaker be disabled. This is done via the dip switches on the rear of the EAFR-101C. For details on dipswitch settings, refer to Section 3.5 Dipswitch settings.

Binary inputs BI5 and BI6

BI5 is the Master Trip/Current input. If set to Master Trip, upon receipt of this input the EAFR-101C will trip without other conditions being present. If set to Current, this input is permissive to tripping if any light signal is received on light sensor channels set to Light and Current (see section 3.5 Dipswitch settings). BI5 also receives a synchronization signal from the EAFR- 110PLV relay is it connected to. This synchronization signal is an integral part of the relay’s self-supervision functions.
BI6 is the Block In input. If a signal is received on this input, the EAFR- 101C will restrain any light signal received for 50 ms. This input should be connected to the Block Out BO2 from all other connected EAFR-101C relays (refer to IB0191003EN).

Auxiliary voltage

The auxiliary power supply voltage is (110-220) Vac/(125-250) Vdc. After powering up the relay, protection is active and operational within 50 ms.
An optional 18-72 Vdc power supply is also available.

Dimensions and installation

The EAFR-101C is either door mounted or panel mounted in stan-dard, 19 in. (482.6 mm) rack (height of 4U and 1/8 of a unit-wide).

Testing

It is recommended that the EAFR-101C relay be tested prior to substation energizing. Testing is carried out by simulating arc light to each sensor and verifying the tripping and LED indication. For arc light simulation, a suitable light source is provided as part of the Eaton AQS Tester kit. If an AQS Tester is not present, a camera flash can be used. A Canon Speedlite® 430EX or equivalent works well. Check that the light source has a fully charged battery(ies) when testing.

Carrying out testing in the light only mode

• Check that the dipswitch setting positions are in accordance with your application.
• Activate the light source close to the EAFR-01 to be used.
•  Verify that the corresponding sensor channel indication LED status is changed to ON.
•  Verify the relay output(s) activation(s) by checking the circuit breaker status or by monitoring trip contact status. If a circuit breaker is connected to a trip output, the circuit breaker should open or contacts operate.
• Note: A best practice is to operate the circuit breaker during testing.
•  Verify that the corresponding relay output(s) LED(s) indication status is changed to ON.
• If the binary output (BO1) signal is utilized, verify the BO1 signal activation by the status change of the relevant input where the binary output signal is connected, or by measuring the signal output voltage.
• If a binary output signal is utilized, verify that the BO1 LED is illuminated.
• Press the SET push-button to reset all indications and latches.

Carrying out testing in light and current mode

• Carrying out testing in light and current mode
• Check that the dipswitch setting positions are in accordance with your application.
•  Activate the light source close to the EAFR-01 to be used and simultaneously activate the binary input BI5 used for over-current conditions. BI5 activation may be done by supplying current to a connected EAFR-110PLV (see AQS Tester Manual IB019011EN).
•  Verify that the sensor channel indication LED status is changed to ON.
•  Verify that the binary input indication LED status is changed to ON.
•  Verify the relay output(s) activation(s) by checking the circuit breaker status or by monitoring trip contact status.
• Note: A best practice is to operate the circuit breaker at testing. The circuit breaker should open or the contacts should operate.
• Verify that the corresponding relay output(s) LED(s) indication status is changed to ON.
• If binary output (BO1 and BO2) signals are utilized, verify the BO signal activation by status change of relevant input where the binary output signal is connected, or by measuring the signal output voltage.
• Verify that the corresponding relay output(s) LED(s) indication status is changed to ON
• Press the SET push-button to reset all indications and latches.

Relay self-check of input connections

The EAFR-101C has a user-initiated self-check test feature that gives the user feedback as to the number of external devices connected to each input on the relay. This feature is particularly helpful in trou-bleshooting, or in verifying that the relay has correctly identified any externally connected devices, such as light sensors, or other relays.
To initiate this test, press the Set button three times quickly. One at a time, the LED for each input will blink for the number of devices connected to that input. For example, if three light sensors are connected to S1, then the LED for S1 will blink three times. The relay continues this function until feedback has been given for all inputs. The relay remains operational during this test, and at no time is the protective function compromised.
