General The Eaton Arc Flash Relay 0S (EAFR-0S) is a sophisticated micro-processor 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 tripping the circuit breaker sourcing the fault current. The EAFR-0S complete system self-supervision function provides the highest level of dependability by continuously monitoring all internal system functions along with external connections. The EAFR-0S 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, off shore, 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-0S is suitable for either medium voltage or low voltage switchgear and motor control center applications in both new and retrofit installations.. EAFR-0S Features The EAFR-0S is a multipurpose arc flash protection relay that can receive light from four different channels of light point sensors and can be applied for variety of applications. The EAFR-0S 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-0S: (0-0) Vac / (5-50) Vdc auxiliary power supply; Four arc point sensor channels (S, S, S, and S); Six binary inputs (BI, BI, BI, BI, BI5, and BI) nominal voltage of Vdc; Three normally open trip relay outputs with direct trip circuit rated contacts (T, T, and T); One normally open electronic lock-out trip relay with direct trip circuit rated contacts (T); Three VDC binary outputs (BO, BO, and BO); One system failure relay, form C output (SF); indication LEDs; and One push-button (SET).

8 . Operation and Configuration. Operation and Configuration. LED Indicator Functions TThe EAFR-0S contains indication LEDs. A user definable text pocket can be slid in under the label for identifying each LED function (except POWER and ERR 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 a LED test. All LEDs are turned on for two seconds and then off. Only the blue POWER LED will remain on. After powered up, the relay goes into protection mode in 50 ms even while the LED test is being performed. During normal operation, only the blue power LED is ON. 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.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..) situation, the corresponding LED for that sensor will start flashing and the ERR LED will activate. The Binary I/O LEDs are indicating the I/O-line status. If any of the lines become active for more than.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.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.

Check why the sensor activated, check the sensor wire connection, or perform system set-up (see Section..: Auto-Configuration (System Setup).. Push-button Description The EAFR-0S 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..) and for resetting the indicators and latched output relays... Auto Configuration (System Setup) When all sensors and binary lines have been connected, an auto-configuration procedure must be executed. The initialization sequence is performed by pressing the Set button for two seconds. The EAFR-0S 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. NNote: To redo auto-configuration for a relay containing less connections (binary inputs/outputs or sensors) than in a previously memorized set-up, a dip-switch (anyone) must be moved back and forth prior to performing auto-configuration. The timeout allowing a new configuration is one minute. Reconfiguration with more connections is allowed without moving a dipswitch. 5

10 . Operation and Configuration. 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 auxiliary power supply is disconnected (see Section.: Non-volatile Memory)..5 Dipswitch Settings EAFR-0S functionality, such as tripping logic, is configured using dipswitch settings. Different trip configurations can be easily programmed by selecting the appropriate dipswitch positions. This gives users the flexibility to change. settings dependent 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 BI for blocking a trip caused by natural light sources. Also, the CBFP configuration may be enabled using the dipswitches (dipswitch number is enabling the CBFP function for corresponding configuration selections). Dipswitches through are used as configuration selection. The configuration number is according to binary arithmetic. Switch equals a count of, switch equals a count of, switch equals a count of, and switch equals a count of five. Dipswitches are located at the back of the relay for easy access (see Figure : EAFR-0S Dipswitch SW and Table : EAFR-0S Dipswitch Setting Selection for details of settings). Figure.

The CBFP feature is applied into this configuration.. Non-volatile Memory All critical system data, including dipswitch settings and auto-configuration file described in Section.., are stored in EPROM non-volatile memory to ensure correct operation and full self-supervision, even if auxiliary power is temporarily lost. Also, all LED indications described in Section. are stored in non-volatile memory in order to provide quick recovery of the system status indication, even if auxiliary power is temporarily lost. This feature is especially important if auxiliary power is lost after tripping. Non-volatile memory does not require a power supply to maintain information and will retain settings and indications permanently without power.

21 . Arc Sensors. 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. Arc light point sensors are typically installed in metal clad compartments, providing quick accurate location of the faulted area. Arc light fiber loop sensors are installed typically to cover a wider protected area with one fiber when no need for more exact fault location exists.. Arc Light Point Sensor EAFR-0 The EAFR-0 is an arc light point sensor with a light sensitive photodiode element activated by receiving arc light. The EAFR-0 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. Typically, one sensor per closed metal clad compartment is used. In open spaces, such as the busbar section, arc sensors should be mounted at a maximum of two meters (.5 ft) apart. The fixed light sensitivity of the EAFR-0-A sensor is 8,000 Lux. The sensor does not require any user settings. The point sensor s light detection radius is 80 degrees. Other point sensors are available with different Lux sensitivities, EAFR-0-B at 5,000 Lux and EAFR-0-C at 50,000 Lux... EAFR-0 Installation and Wiring The EAFR-0 point sensor can be installed either on or through the compartment wall. An example of on the wall mounting is seen in Figure. The EAFR-0 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 back side of the sensor. No external mounting plates are needed. The EAFR-0 comes without the connection cable. Connection cable installation on site is simple. The 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 connectors are located at both ends of the sensor for series connecting a maximum three sensors in one line. Figure 5.

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..: 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 ERR LED is illuminated.. Application Examples The EAFR-0S may be applied to a variety of power switchgear and control gear layouts and technologies. Some typical applications are described in this section. Please consult your nearest Eaton representative for a solution to your particular application.. MV or LV Double Busbar Application with Current and Light condition The EAFR-0S may be applied requiring both over-current and arc light conditions for trip. In this application, tripping is performed only if both conditions are fulfilled simultaneously. Typically, the over-current condition is obtained from an EAFR-0 relay or monitored by non-eaton products (e.g. generic feeder protection relay) and the total operation time is then dependent on device feeding the over-current signal to EAFR-0S. Figure shows an example of a double busbar arc protection system applying both over-current and arc light for tripping. S channel is typically monitoring the outgoing cable compartment. S channel is monitoring the breaker compartment. S and S are respectively monitoring the reserve busbar and main busbar. The busbar arc light fault information is sent out through the binary output channel BO (main busbar) and channel BO (reserve busbar). Figure. Double Busbar Application. If a sensor failure occurs, the relay will go into ERR mode. The ERR LED will illuminate, the SF relay will released-energize, 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 channel blocked. If the error is resolved, the ERR 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 ERR LED will turn off. If one or more of the sensors are disconnected, the healthy sensors remain in use and relay remains operational. The EAFR-0S will remain in error mode until the disconnected sensors are repaired. CB S S If a dipswitch setting is changed after the auto-configuration function (see Section..: Auto Configuration) has been executed, the relay will go into SF alarm mode. The configured (stored) setting is however still valid and the relay is still operational. T S S T(Trip Alarm ) BI BO BO EAFR-0S 8

The position of the breaker can be manually connected with either the main busbar or reserve busbar. For indicating the precise breaker location, its position information is sent to EAFR-0S via the binary input channel BI (main busbar) or BI (reserve busbar). The trip contact T is responsible for tripping the breaker. The trip contact T gives trip alarm information synchronically. The connection of this example application is also shown in Section 8: Wiring Diagram.. Connections Figure. EAFR-0S Terminals at the Rear Plate. X X. Circuit Breaker Failure Protection (CBFP) The EAFR-0S includes a selective circuit breaker failure function that can be enabled by the dipswitch settings (see Section.5: Dipswitch Settings). When enabled, the breaker failure function activates when the tripped breaker fails to operate. The breaker failure function is activated if the EAFR-0S detects the presence of light after a set operating time. When the EAFR-0S is set to operate on light and current, both parameters must persist to activate CBFP. Breaker failure can be set to operate either on 00 ms or 50 ms delay (see Section.5: Dipswitch Settings) S S S S ON OFF S/S/S Chan L L+C S Channel L L+C T / T Latch N L CBFP Time Config.

24 . Connections. Outputs.. Trip Relays T, T, and T The EAFR-0S relay has integrated trip relays T and T for tripping of the circuit-breakers. T and T relays are normally open type (NO) relays. Trip relay T is a (NO) trip relay that operates anytime the T or T 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 BO, BO, and BO Three binary outputs are available (+ Vdc). The binary output function can be configured using the dipswitches (see Section.5: Dipswitch Settings. NNote: The binary output is polarity sensitive (see Section 8: Wiring Diagram)... System Failure (SF) Relay The SF relay is a form C type (NO/NC) and is energized in the healthy condition. Whenever the EAFR-0S 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-0S returns to a healthy condition and SF relay is again energized... Binary Inputs BI, BI, BI, BI, BI5, and BI The EAFR-0S contains six binary inputs. Typically, BI and BI are reserved for the breaker position signal information. In the most applications, the BI is responsible for the receiving over-current from the EAFR-0P. The BI, BI5, and BI can be used for receiving a trip signal or arc light signal (see Section.5: Dipswitch Settings). NNote: When the EAFR-0S receives an over-current signal from a non-eaton device, the actual operation time depends on the operation time of the external device and so the total operational time cannot be specified or guaranteed. The inputs are activated by connecting a dc signal exceeding the specified nominal threshold level of the corresponding input. The nominal threshold level is Vdc. The actual activation of the binary input occurs at 80% of the specified nominal threshold value (i.e. Vdc).. Auxiliary Voltage The auxiliary power supply voltage is (0-0) Vac / (5-50) Vdc. After powering up the relay, protection is active and operational within 50 ms.. Inputs.. Arc Sensor Channels S, S, S, and S The EAFR-0S has four arc point sensor channels.

Testing is carried out by simulating arc light to each sensor and verifying the tripping and LED indication. For arc light simulation, a superior camera flash type is used: Canon Speedlite 0EX or equivalent. For testing of non-latched signals and the CBFP function, use a Mini Maglite Cell AAA or equivalent type of flashlight. Check that the camera flash or flashlight has fully charged battery(ies) when testing. M 59 (.) 8 (.) 0. Carrying Out Testing in the Light Only Mode. Check that the dipswitch setting positions are in accordance to your application.. Activate the camera flash within 0 cm (.8 in.) of the EAFR-0 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. The circuit breaker should open or contacts operate. NNote: A best practice is to operate the circuit breaker during testing. 5. Verify that the corresponding relay output(s) LED(s) indication status is changed to ON.. If the binary output (BO) signal is utilized, verify the BO signal activation by the status change of the relevant input where the binary output signal is connected, or by measuring the signal output voltage. NNote: The BO signal is a non-latched type.. If a binary output signal is utilized, verify that the BO LED is illuminated. 8. Press the SET push-button to reset all indications and latches.

Testing the Arc Flash Protection Unit Operation Time The EAFR-0 operation time test is not required at commissioning as it is performed by Eaton as a type test and routine production test. Refer to the routine test reports sent with EAFR-0 relay and consult your nearest Eaton representative for type test reports. However, if it is deemed necessary, a site timing test may be conducted using the following instructions.. Use a calibrated relay test set.. Connect an output from the relay test set to the camera flash (Metz 0B or equivalent input) for initializing the flash and configure a relay test set timer to be started simultaneously with flash.. Connect the EAFR-0 trip output T, T, or T to the relay test set input and configure the input to stop the timer.. Place camera flash to a maximum 0 cm (8 in.) distance of the EAFR-0 or EAFR fiber sensor. 5. Initiate the flash and timer using the relay test set output.. Read the measured time between simulated arc and trip contact operation.. Subtract the digital input delay of the relay test set from the final measured time if applicable. For specific test instructions consult the manufacturer of the relay test set.
