NOTE The removal/drainage of both main battery and RTC battery will delay sensitivity of the product. The presence/non-drainage of main battery and removal/drainage of the RTC battery will not impact the sensitivity of the product.
6.4.5 The 7SR45 Argus relay has 2 batteries: a main battery CR123A and a coin cell RTC battery CR1632. This section is applicable to the main battery CR123A, 3 V 1400 mAh Li non-rechargeable battery . The battery is used to energize the device when auxiliary voltage or phase current or USB are not available.
Sleep Mode The 7SR45 Argus Relay goes into sleep mode when the auxiliary power/CT power, and USB power are not available. When the relay is in sleep mode, you can access the LCD by pressing the BAT ON/OFF key. In case of inactivity, the relay goes to the sleep mode after 60 s.
Page 72
6.4 Modes of Operation NOTE Siemens recommends replacing the battery when the LOW BATTERY indication is displayed. In the low battery mode, the following relay operations lead to insufficient operating voltage. The LCD displays the INSUFFICIENT ENERGY message and the relay enters the sleep mode.

In Service Operation 6.6 Indications Reset via Communication Protocol You can initiate acknowledgment of stored indications also via communication through a connected substa- tion automation technology system. This can occur in conformance to standards (Modbus RTU, IEC 60870-5-103) or via configuration (mapping) of the LED reset input signal for any protocol. Stored LEDs, output contacts, and spontaneous fault displays are reset.
In Service Operation 6.7 Logs Logs Data Storage 6.7.1 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.
The stored events can be cleared by using the DATA STORAGE > Clear Events setting in the HMI or from Reydisp. NOTE Before you delete the content of a log on your 7SR45 device, save the log with Reydisp Evolution on the hard disk drive of your PC. NOTE...
Edit Measured and Metered Values Overview of Measured and Metered Values 6.8.1 The 7SR45 devices have numerous measured and metered values. The following Table 6-4 gives you an over- view of the scope and sequencing principle. Measured and metered values are referred to hereafter as meas- ured values.
Setting Time and Date You can set the date and time of your 7SR45 device using the relay fascia as well as Reydisp Evolution. Settings on the Device Using the On-Site Operation Panel To reach the settings for date and time from the main menu, use the navigation keys on the on-site operation panel.

Commissioning 7.2 Test Suite Integrated in the Device Test Suite Integrated in the Device Testing Protection Functions 7.2.1 The purpose of this test is to verify the correct setting of protection functions and the routing of signals. To do this, you can feed the test signals with test equipment. Digital test equipment offers you multiple test programs and test sequences.
Commissioning 7.3 Initial Startup Initial Startup Establishing Readiness for Operation State It is assumed that you have gone through steps in chapters 1 to 4. Check the connection of the auxiliary power supply if it is a dual powered relay (type1: DC 24 V to 60 V and type2: AC 60 V to 240 V/ DC 60 V to 240 V) or phase CT connection if it is a self powered relay.
Commissioning 7.4 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/VT CONFIG Set phase CT and earth ratio FUNCTION CONFIG...
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 and Outputs Check that the connection from the output of the testing equipment to the device is correct and the binary inputs and outputs are connected correctly.
Device Maintenance 8.1 Execute Checks Execute Checks Protection-Function Test 8.1.1 General NOTE When performing a protection-function test, make sure that it does not lead to any undesired tripping. Likewise no information must be transmitted to a higher-level systems control where the operator may incorrectly interpret it.
The relay is functional only when the setting error message is acknowledged. 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.
