1MRS 752264-MUM 3.3. Protection relay indications 3.3.1. Indicator LEDs 3.3.1.1. Green indicator LED The operation of the relay can be monitored by means of three different kinds of indications on the HMI: Three indicator LEDs with fixed functionality: Ready, Start/Alarm and Trip Eight programmable indicator LEDs A text message on the display The protection functions are not affected by fault indications. When a protection stage starts or generates an alarm, the yellow indicator LED will be lit. When a protection stage trips, the yellow indicator LED will remain lit and the red indicator LED will be lit. When a starting protection stage is blocked, the yellow indicator LED will start to blink. The yellow indicator LED will also be lit to indicate an alarm from a protection stage. Green_a 3.3.1.2. Yellow indicator LED Fig. 3.3.1.1.-1 Green indicator LED Two different functions are embedded in the green indicator LED: power on and internal relay fault (IRF). Indicator off: The auxiliary voltage is not connected. Lit indicator: The relay is in operation. However, a less severe fault (warning) may have occurred. Refer to section Indications for internal relay faults (IRFs) and warnings. Blinking indicator: An internal relay fault requiring repair by an authorized service supplier has occurred. Refer to section Indications for internal relay faults (IRFs) and warnings. Yellow_a Fig. 3.3.1.2.-1 Yellow indicator LED Indicator off: No protection stage has started and there are no thermal alarms. 28

1MRS 752264-MUM Lit indicator: 3.3.1.3. Red indicator LED A protection stage has started or generated an alarm. The start and alarm indication can be selected to be either latching or non-latching with the SGF switches. A non-latching indication will automatically be cleared when the fault has disappeared and the protection stage has been reset, whereas a latching indication will remain lit until manually cleared. Blinking indicator: Starting protection stages have been blocked by an external digital input signal. The blocking indication is non-latching, i.e. it will disappear with the digital input signal. The yellow indicator LED will continue blinking for as long as a protection stage remains blocked. The blocking indication will disappear with the digital input signal or when the protection stage is no longer starting. If a protection stage is blocked when other protection stages are starting, the indicator will continue blinking. This because a blocking indication has a higher priority than a starting indication. Red_a Fig. 3.3.1.3.-1 Red indicator LED Indicator off: No protection stage has tripped. Lit indicator: A protection stage has tripped. The trip indication is latching, i.e. it will remain lit until manually cleared. 3.3.1.4. Programmable indicator LEDs In addition to the three fixed LEDs, the relay includes eight LEDs which you can program to indicate the status of different type of relay signals. The programmable LEDs can indicate the following information: Trip signals from protection stages Alarm signals from protection stages Motor status and restart inhibit status Status of the digital input signals Rout the signals to the LEDs via switchgroups SGL1...SGL8; to LED1 with the switches of switchgroup SGL1, to LED2 with those of SGL2, and so forth. Each SGL consists of 20 alternative signals. For detailed information on the signals, refer to the Technical Reference Manual. The LEDs are non-latching by default but you can also set them to operate as latching via switchgroup SGF5. 29

1MRS 752264-MUM 3.3.2. Indication messages For instructions on setting the switchgroups, refer to section Switchgroups. The messages give an overview of protection operations and internal relay faults. 3.3.2.1. Operation indication messages When a protection stage starts, the text START will appear on the display along with the name of the function. Additionally, in case of a latching start indication, the name of the energizing input(s) which caused the fault will be displayed (except for the motor start-up supervision based on thermal stress calculation and the unbalance protection). The yellow indicator LED will be lit. I>> START L1 StartIEC_a Fig. 3.3.2.1.-1 Latching start indication When a protection stage trips, the text TRIP will appear on the display along with the name of the function. Additionally, the name of the energizing input(s) which caused the fault will be displayed (except for the motor start-up supervision, phase unbalance, phase reversal, thermal overload and temperature protection). The red indicator will be lit. I>> TRIP L1/L2 TripIEC_a Fig. 3.3.2.1.-2 Trip indication In case of an alarm from the thermal overload or temperature protection, the text ALARM will appear on the display along with the function symbol and the yellow indicator LED will be lit. > ALARM AlarmIEC_a Fig. 3.3.2.1.-3 Alarm indication In case of a restart inhibit state, the text RESTART INHIBIT will appear on the display. The state will not affect the start/alarm and trip LEDs, but instead you can use a programmable LED to indicate the state; refer to section Programmable 30

1MRS 752264-MUM indicator LEDs. The text message for the restart inhibit state is non-latching, whereas the status indication via a programmable LED can be either latching or nonlatching. The restart of a motor can be inhibited by the thermal protection, the cumulative start-up time counter or an external digital input signal. For the priority of indications for the restart inhibit state; refer to section Priority of operation indication messages. RESTART INHIBIT S tsi RestInhIEC_a Fig. 3.3.2.1.-4 Restart inhibit indication Latching and non-latching indications A latching operation indication message will remain on the display until manually cleared or until replaced by a message of higher priority. However, if the fault is stable and has not disappeared, the operation indication message and the LED(s) will not be cleared. An operation indication generated by a non-latching start will automatically be cleared when the stage is reset. Priority of operation indication messages The messages on the display have a certain priority order. If different types of indications are activated simultaneously, the message with the highest priority will appear on the display. The priority order of the messages: 1. CBFP 2. Trip 3. Start/Alarm 4. Restart inhibit 4.1. Thermal protection 4.2. Cumulative start-up time counter 4.3. External restart inhibit When several protection stages generate starts or alarms, the last start/alarm indication message will be displayed. When several protection stages trip, the first trip indication message will be displayed until the time, as specified by the NEW TRIP IND. setting value, has expired. After this, a new trip indication message can displace the old one. A hidden trip indication message can be brought forward by pressing. 3.3.2.2. Disturbance recorder indication When the display is in the idle mode, an asterisk * indicating that the disturbance recorder has been triggered and is ready to be unloaded, will be shown in the lower right-hand corner of the display. 31

1MRS 752264-MUM 3.3.2.3. Indications for internal relay faults (IRFs) and warnings There are two types of fault indications; internal relay fault (IRF) indications and warnings. Internal relay faults prevent relay operation while less severe faults (called warnings) allow continued relay operation with full or reduced functionality. Internal relay fault (IRF) At permanent internal relay faults, the relay is no longer protecting and has to be sent for repair at an authorized service supplier. When the self-supervision system detects a permanent internal relay fault, the green indicator LED will start to blink and the text INTERNAL FAULT and a fault code will appear on the display. State the fault code when sending the relay for service. As long as the green indicator LED (ready) is blinking, the fault indication cannot be cleared. In case an internal fault disappears, the green indicator LED will stop blinking and the relay will be returned to the normal service state, but the fault indication message will remain on the display until manually cleared (or a motor start up begins). INTERNAL FAULT FAULT CODE :30 IntFault_a Fig. 3.3.2.3.-1 Permanent IRF The fault code is of a numerical kind and identifies the fault type. The fault codes are listed in the table below: Table 3.3.2.3-1 IRF codes Fault code Type of fault 4 Error in output relay PO1 5 Error in output relay PO2 6 Error in output relay PO3 7 Error in output relay SO1 8 Error in output relay SO2 9 Error in the enable signal for output relays PO1,PO2,SO1,SO2 10, 11, 12 Error in the feedback, enable signal or output relays PO1,PO2,SO1,SO2 20, 21 Auxiliary voltage dip 30 Faulty program memory 50, 59 Faulty work memory 51, 52, 53 2), 54, 56 Faulty parameter memory 1) 55 Faulty parameter memory, calibration parameters 75 RTD module faulty 80 RTD module missing 81 RTD module unknown 82 RTD module configuration error 85 Power supply module faulty 86 Power supply module unknown 90 Hardware configuration error 95 Communication module unknown 32

Warning Type of fault In case of a less severe fault (warning), the relay will continue to operate except for those protection functions possibly affected by the fault. At this type of fault, the green indicator LED will remain lit, but the text WARNING with a fault code or a text message indicating the fault type will replace the name of the motor drive on the display in the idle mode. Some of these faults can be corrected by a relay operator at site. After the fault has disappeared or been corrected, the message will automatically be cleared. WARNING BATTERY LOW Warning_a Fig. 3.3.2.3.-2 Warning with text message If more than one type of fault occur at the same time, one single numeric code which indicates all the faults will be displayed. For instance, 2049 implies two faults: the battery is low and the temperature sensor RTD6 is faulty. The code is composed of the weighting factors assigned to each fault type as follows: 1 + 2048; see Table 3.3.2.3-2. WARNING FAULT CODE: 2049 Warning2_a Fig. 3.3.2.3.-3 Warning with numeric code Table 3.3.2.3-2 Warning codes Fault Weighting factor Description Battery low 1 Battery voltage level low - Battery should be replaced - Warning will not be displayed if non-volatile memory settings have been set to 0 - In case only this warning is active, it will be displayed in text format (BATTERY LOW) 33
