and the NPS current as a multiple of the full load
current (FLA) of the motor. The ground fault current, In, as a percentage of
the rated current of the CT used. When an element generates a pickup or an
alarm signal, or when a motor start up ends, the maximum currents during
the pickup period will be stored. When an element trips, the values at the
time. of the trip will be stored.
*
Thermal stress value, I

2
x (48/14 TDLY). If start-up supervision based on thermal stress
calculation has been selected and the pickup criteria for the element have
been met, the maximum calculated thermal stress value will be stored. The
value 100% indicates that the calculated thermal stress has exceeded the
set reference value.
*
Number of motor start ups. The number indicates the motor start up during
which the event was stored and provides history data since last
commissioning. Writing to parameter V53 will reset the number of motor start
ups.
*
Thermal level, as a percentage of the maximum thermal level of the motor, at
activation of a pickup, alarm or motor start-up signal.
*
The maximum thermal level during the time the pickup, alarm or motor
startup signal was active, as a percentage of the maximum thermal level of
the motor, or in case of a trip, the thermal level, as a percentage of the
maximum thermal level of the motor, at activation of a trip signal.
*
The temperatures from inputs RTD1...6 (optional) and the resistance values
of thermistors 1 and 2 (optional). When an element generates a pickup or an
alarm signal, or when a motor start up ends, the maximum temperature(s)
and thermistor resistance value(s) during the pick-up period will be stored.
When an element trips, the temperatures and resistance values at the time
of trip will be stored.
*
Duration of the last pickups of elements 48/14, 50P, 46, 51N and 37, and of
the last alarms and trips of elements 49/38-1 (optional) and 49/38-2
(optional), expressed as a percentage of the set or calculated operate time.
The timing will start when an element picks up. The elapsed operate times of
elements 49/38-1 and 49/38-2 for the RTD input which has been activated
the longest in their respective groups. A value other than zero indicates that
the corresponding element has picked up whereas the value 100% indicates
that the operate time of the element has elapsed, i.e. the element has
tripped. If the operate time of an element has elapsed but the element is
blocked, the value will be 99% of the set or calculated operate time.
*
Time stamp for the event. The time when the collected data was stored. The
time stamp is displayed in two registers, one including the date expressed as
yy-mm-dd, and the other including the time expressed as HH.MM; SS.sss.
EVENT 2 Same as EVENT 1.
EVENT 3 Same as EVENT 1.
EVENT 4 Same as EVENT 1.
EVENT 5 Same as EVENT 1.
Number of
pickups The number of times each protection element, 48/14, 50P 46, 51N and 37, has
picked up, counting up to 999.
