Text of the circular

Data logger is a Microprocessor 
based system, which helps in 
analyzing the failures of relay inter
analyzing the failures of relay inter
locking system (PI & RRI) / 
Electronic Interlocking system 
(EI).
Specification no.IRS S 99/2006

Data logger acts like a BLACK BOX
It records and stores all the information regarding the changes
that take place in the status of Relays, AC/DC voltages with Date
d Ti
and Time.
The same Data can be transferred to a FAS (Fault Analysis
System) to make further analysis of stored data in On line /Off line.
Print out of the data can be obtained by connecting a Printer to
the DATA LOGGER or to the FAS.

PRINTER DATA LOGGER

(a) Data logger helps in monitoring typical failures such as 
intermittent, auto right failures.
(b) It helps in analyzing the cause of accidents.
(c) It helps in detecting the human failures / errors such as :
(i)D i

(SPAD)
(i)Drivers Passing signal at Danger (SPAD).
(ii)Operational mistakes done by Optg./Electrical/Engg/S&T
staff.
(iii)On line and Off line track simulation is possible.
(iv) It helps as a “Diagnostic tool” in preventive maintenance
of signaling gears.

Data stored in data logger is of two types
DIGITAL DATA:
Relay contacts of PI/RRI & auto signal
Relay contacts of PI/RRI & auto signal,
Bits of EI’s etc.
ANALAG DATA:
AC/DC bus bar voltage (24V, 60V, 110V &230V etc.)
EX: Axle counter channel voltage, Temperature
