Reclosing Event Memory (REM)

Data Retrieval

The following procedure is an example of retrieving data from the Reclosing Event Memory.
STEP 1.

Remove the relay from service.

STEP 2.

Position the NORMAL/TEST switch (on logic board) to TEST.

STEP 3.

Position RESET thumbwheels to 00.

STEP 4.

Adjust RECLOSE TIME 3 LSD thumbwheel to the desired type of event data to be retrieved.

(Refer to Table 3-4).

STEP 5.

Verify that the appropriate STATUS LEDs light. The correlation between the STATUS LEDs

and the RECLOSE TIME 3 (LSD) verify proper memory addressing.

STEP 6.

Position RECLOSE TIME 1 thumbwheels to 000.

STEP 7.

Observe STATUS 3 LED and RESET LED. These two LEDs guide the operator as to wheth-

er the RECLOSE TIME 1 thumbwheel number is less than or greater than the actual number

of events stored in memory.

STEP 8.

Begin with MSD of RECLOSE TIME l and increase setting until RESET LED lights, and

STATUS LED goes out. Setting is now greater than event count in memory. Decrease setting

one number.

STEP 9.

Increase the setting on RECLOSE TIME 1, 2nd MSD, until RESET LED lights, and then

decrease the setting one number.

STEP 10. Increase the setting on RECLOSE TIME 1, LSD, until the STATUS LED 3 and RESET LED

light. The number shown on RECLOSE TIME 1 setting equals the number of events record-

ed.

Data Retention

To retain the data that is stored in memory and resume the event count, proceed as follows:
STEP 1.

Position the NORMAL/TEST switch (on the logic board) to NORMAL.

STEP 2.

Return all front panel controls to their normal service positions.

STEP 3.

Return relay to service. Relay will resume normal operation and the event count from that

point.

Clearing Stored Data

To clear the old data from memory before returning the relay to normal service, proceed as follows:
STEP 1.

Toggle RESET lever once. This action clears memory. Memory clear can be verified by

keeping RECLOSE TIME l at 000, and by rotating the LSD of RECLOSE TIME 3 from 0

through 5. The STATUS 3 and RESET LEDs should light at each setting.

STEP 2.

Position the NORMAL/TEST switch (on the logic board) to NORMAL.

STEP 3.

Return all front panel controls to their normal service position.

STEP 4.

Return the relay to service. The relay will resume normal operation and begin a new count of

events.
