9BSELF-DIAGNOSIS FUNCTIONS
PROTECTION, CONTROL AND METERING FUNCTIONS
2.9. SELF-DIAGNOSIS FUNCTIONS
2.9.1. INTERNAL SELF-DIAGNOSIS
The smART P500 relay includes routines that continuously check the status of the
following parameters:
Internal battery voltage.
Auxiliary voltage.
Hardware.
Analog-digital converter
FLASH memories
SDRAM memories
SRAM memories
FPGA
By using the View / Status option in software proART, the result of these self-diagnosis
routines can be examined. The error codes shown on the display of the relay are:
Error
No.
Signal
Comment
1
Battery level
Low level of clock and SRAM backup battery
2
Auxiliary
voltage level
Low level of the relay auxiliary voltage (user configurable)
3
CAD
Error in the analog-digital converter
4
FPGA
Error in FPGA
5
SDRAM
SDRAM memory error
6
SRAM
SRAM memory error
7
FLASH2
Error in FLASH memory where oscillographic records are saved
8
FLASH
Error in FLASH memory where the relay code and configuration are
stored.
9
7FFF
Internal Error
10
RTC
Error in the real time clock
11
Ethernet
Ethernet module error
