    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.

  • Page 83: General Information

    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.
