1.1.4 Memory Control Card / PCMCIA Card
The Micro controller based Memory card is an intelligent card and
generates the status of the memory and communicates with the main
controller card internally with a predefined protocol.
The memory is divided in to three partitions, attribute memory, fine
data and Coarse data. The fine data is stored at every second when
the train is in motion in a loop form for the period of 6 Hours . When
the train is in halt the fine data is not written into the memory. Like
wise the coarse data is stored at every 20 sec during the EMU run and
halt for 45 days in a loop form. In case of any accident, the authorized
person has to break the memory freeze glass fitted on the front panel
of the unit .and switch on the memory freeze switch. This prevents the
fine data storing into the memory till the memory freeze switch is off.
The PCMCIA card is a 68-pin, Type II is used and conforms to all
International Standard s with push button ejector for easy loading and
ejection.
1.1.5 Stepper Card

When the speed of the locomotive exceeds the set speed limit, an
audible alarm sounds and an OVER SPEED LED glows up, OVER
SPEED indication will blink on the LCD display, to have audio
visual alarm.
The audible alarm stops sounding and the Over Speed LED stops
glowing when the loco speed comes below the set speed.
2.No PCMCIA Card :
If PCMCIA is removed from the compartment, this error will blink up
on the display and System Fail LED glows. Necessary action is to
be taken by the shed staff to insert the PCMCIA in the slot. Keep
the PCMCIA card properly and the error NO PCMCIA CARD will
disappear on the display.
3. Internal Memory Fail :
If by chance the display shows up the Internal memory fail
continuously along with the SYS/FAIL lights up, i.e. system
indicating that the internal memory is not writing due to memory fail
condition existing in the memory card. Once this lights up Simply

change the main card of the RCI unit, and send back the fail card to
factory for repair/ replacement.
CAUTION: THE SYSTEM IS HAVING THE CAPABILITY TO
RECHECK THE INTERNAL MEMORY AND TRIES TO RECTIFY
THE FAULT FOR 10 TIMES. IF IT IS NOT ABLE TO RECTIFY THE
FAULT , THEN INDICATES INTERNAL MEMORY FAIL
CONTINUOUSLY.
4. External Memory Fail :
The fault is similar that of internal memory fail but it checks the
conditions for External memory. In case the fault continuously
appears on the display just remove the PCMCIA card and put the
new PCMCIA.
5.
Memory Freeze :
A memory freeze switch is provided on the front panel of the speed
recorder unit. A breakable glass is provided on the switch. In case
the fine memory is to be freezed, to access the written data and not
to be over written, then the option is to brake the glass and
MEMORY FREEZE switch should be put to ON condition. Once the
switch is ON fine memory is freezed and system will not write/ or
access the Fine memory area till the Memory Freeze switch is put to
OFF condition.
As long as the MEMORY is freeze the fault indication appears on
the display and a Red LED indication will appear in the memory
freeze compartment.
Only fine memory will be free zed during the memory freeze switch
is in ON condition. Long term memory will however be written.
6. Memory Full :
As per the specification if the data in the memory is more than 85%
of occupancy, then the systems should indicate the user as full
memory and cautions the user to down load the data at the earliest
to avoid the loosing the earlier data because of the looping format
of the data structure.
During this time SYS FAIL /Memory full LED lights up and this is an
indication to the user to verify the memory capacity on the display
