Cleaning
Warning: Before cleaning the IED, ensure that all AC and DC supplies
and transformer connections are isolated to prevent any
chance of an electric shock while cleaning.
Only clean the equipment with a lint-free cloth dampened with clean water. Do not use detergents,
solvents or abrasive cleaners as they may damage the product's surfaces and leave a conductive
residue.
2.4 Troubleshooting
The relay continuously monitors the hardware and detects any hardware fault/error. In case of
hardware failure relay displays the corresponding error code on the LCD. These faults errors are
stored in the error log file and can be viewed from “Error Log” menu. Error log is stored in 16 bit
integer. The bit definition applicable to P15D is as under:
Bit 10 -
15
Bit 9 Bit 8 Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0
