In Service Operation 6.7 Indications Indications General 6.7.1 During operation, indications deliver information about operational states, that include: • Measured data • Device supervisions • Device functions Data records are stored in the non-volatile memory. The Data Storage menu contains the settings for clearing events and faults.
In Service Operation 6.7 Indications [sc_events_faults, 1, --_--] You will find additional information about deleting and saving logs in 6.8.2 Saving and Deleting the Logs. Displaying Indications 6.7.3 Displayed indications in Reydisp and on the on-site operation panel are supplemented with the following information: Table 6-5 Overview of Additional Information...
Page 64
In Service Operation 6.7 Indications Reset with Reydisp Evolution You can reset stored indications via Reydisp Evolution in online mode. Reset via Communication Protocol You can initiate acknowledgment of stored indications also via communication through a connected substa- tion automation technology system. This occurs in conformance to standards (Modbus RTU, IEC 60870-5-103) or via configuration (mapping) of the LED Reset input signal for any protocol.
In Service Operation 6.8 Logs Logs Data Storage 6.8.1 The relay stores 2 types of data: Fault records, event records. Data records are stored in the non-volatile memory. The Data Storage menu contains the settings for clearing events and faults. Fault Records (Trip Log) The fault records are generated when the protection function detects a fault condition and the trip alert message appears on the LCD.
In Service Operation 6.8 Logs Saving and Deleting the Logs 6.8.2 Deleting the logs of the device in the operating state is not required. If storage capacity is no longer sufficient for new indications, the oldest indications are automatically overwritten with new incoming events. For the memory to contain information about the new faults in the future, for example, after an inspection of the system, a deletion of the log makes sense.
In Service Operation 6.9 Edit Measured and Metered Values Edit Measured and Metered Values Overview of Measured and Metered Values 6.9.1 The 7SR46 devices have numerous measured and metered values. The following Table 6-7 gives you an over- view of the scope and sequencing principle. Measured and metered values are referred to as measured values.

Commissioning 7.1 Overview Overview This section contains information about the commissioning of the 7SR46 device. Test functions in the device support you during testing, simplify testing processes, and reduce testing times. The secondary test is used for checking: • Correct setting of functions •...
Ensure that all test equipment and leads have been correctly maintained and are in good condition. • Siemens recommends connecting all power supplies of the test equipment via a residual current relay (RCD) which must be located as close to the supply source as possible.
Commissioning 7.2 Before Testing Test Equipment 7.2.3 The following test equipment is required: • Secondary injection equipment with integral time interval meter • Primary injection equipment • A power source with rated voltage within the working range of the auxiliary-supply rating of the relay. •...
Commissioning 7.3 Applying Settings Applying Settings The relay settings for the particular application must be applied before any secondary testing occurs. If relay settings are not available, then the relay with default settings can be used for precommissioning tests. Note that the tripping and alarm contacts for any function must be programmed correctly before any scheme tests are carried out.
Commissioning 7.4 Initial Startup Initial Startup Establishing Readiness for Operation State It is assumed that you have gone through steps in chapters 1 to 6. Check the connection of the auxiliary power supply. You can also read the rated voltage range from the name plate. After successful testing of your voltage source, switch it ON.
Commissioning 7.5 Precommissioning Tests Precommissioning Tests Secondary Tests In the numerical relay test kits, select the appropriate burden (VA) for testing the relay functionalities. The following settings must be configured on the relay during testing. Parameters Settings System frequency Set nominal frequency CT CONFIG Select CT type and set I value...
Startup. The device is ready for operation. If devices are built into cabi- nets, additional wiring and communication connections are necessary. Siemens recommends the following procedure in this order: Testing Binary Inputs, Binary Outputs and External Trip Input Check that the connection from the output of the testing equipment to the device is correct and the binary inputs, binary outputs and external trip input are connected correctly.
Device Maintenance 8.1 Execute Checks Execute Checks General Make sure that the HEALTHY LED (Green) on the front fascia lights up. This is how the device indicates ² that it is properly functioning and that no failures have been observed during self-monitoring. Make sure that the LEDs on the front fascia present a plausible image of the actual state of the device.
Device Maintenance 8.2 Self-Monitoring Self-Monitoring The 7SR46 Argus relay is built in with several self-monitoring features. The self-monitoring is performed peri- odically when the relay boots up. The supervision includes monitoring of power supply signals, code execution watchdog, memory checks by checksum, RTC check, and battery health checks. The Healthy LED is illumi- nated when the internal power supply signals are healthy.
Page 82
Device Maintenance 8.2 Self-Monitoring NOTE If the device is faulty due to a Card error and/or MLFB error, it must be returned via the standard Siemens returns process. Contact your regional office. NOTE Internal supply voltage error and card error is seen on device HMI only when user applies CT power or auxil- iary power supply.
Device Maintenance 8.3 General Information General Information No special maintenance is required for 7SR46 devices. The only maintenance measure is to replace the battery. Since the device is mainly self-monitoring, hardware and software errors are automatically forwarded. This action minimizes any downtime of the device. It also eliminates the need for frequent maintenance inspec- tions.
Check the battery healthy voltage. Additional Support If these measures do not lead to the desired result, the support team will help you. Please contact the local Siemens office or contact customer support: • Phone: +49 911 2155 4466 •...

Device Maintenance 8.4 Troubleshooting NOTE • Keep the device serial number at hand for the support team • Read out the version of the installed firmware. • Read the device-related log (settings files, fault records, event records, IRF statuses) of 7SR46 device with Reydisp Evolution so that the support employee has all the necessary information.
When returning the device ensure the protective film is inserted between the battery and the battery clip. Pack the complete device. ² In order to return the device to the Siemens factory or any Siemens location, contact the customer ² support center and follow the instructions specified by them.
Device Maintenance 8.6 Firmware Update Firmware Update In the 7SR46 Argus relay, firmware can be updated by performing the following procedure: How to proceed Connect the relay to a local PC using a USB cable. ² Run the valid executable file from the local PC. ²...
The confirmation ID validation screen also displays a numerical code. If the confirmation ID is lost or forgotten, you can communicate this code to the Siemens customer support representatives and the confirmation ID can be retrieved. The 7SR45 Argus relay allows you to set the confirmation ID via SETTING MODE > SYSTEM CONFIG > Pass- word.
