Description of Changes
G A March 2004
Correction to the fault recorder window for current based trips
so that it can terminate properly once the FAULT_REC_TRIG
signal (DDB 288) is reset. Previously it needed to wait for
Relay 3 to reset also before termination
Power measurement limits added to prevent non zero values
with no current voltage. Also power factor measurements
Resolved possible reboot caused by failure to time sync from
DNP 3.0 when IRIG-B is active which is also providing the
time sync. Now any failure of the DNP 3.0 to time sync will
only produce a maintenance record
Resolved possible problem with disturbance recorder
triggering which could cause loss of disturbance record data,
temporary freezing of the user interface or loss of rear port
Resolved unreliable MODBUS framing
Resolved creation of spurious password expired event when
menu cell or MODBUS register is accessed
Resolved error code 0x 8D840000
Resolved incorrect derived ‘IN’ value on front panel default
display
