Instructions for the FP-6000 Protective Relay
5.4.8 Cold Load Pickup Settings
A greater amount of current than normal load current may be
experienced due to the load inrush when manually or
automatically closing the breaker after it had been open for a
prolonged time. This high starting current causes some
overcurrent elements to unnecessarily trip the breaker. The cold
load pickup function prevents this from happening. The cold
load pickup function is initiated only if:
1) Cold load pickup control function is enabled.
2) The breaker had been opened for a specified amount of
time before closing.
3) Not in the process of auto-reclosing.
Once a cold load pickup control is initiated, the instantaneous
overcurrent elements may be blocked at the user’s choice and the
time inverse overcurrent elements may also be desensitized at
the user’s choice. When the load current drops below a certain
level for a specified time all the OC elements will use the normal
pickup settings. The cold load pickup timeout setting is used for
terminating the use of cold load pickup control if the load inrush
diminishing signal has not been received within the timeout.
The cold load pickup threshold setting (P1 in figure 25) is an
inrush current indicator. When the load current exceeds this
level, occurrence of load in rush will be identified and the load
inrush diminish timer will be initiated.
5.4.9 Clock Settings
Once the FP-6000 is properly installed, the real-time clock needs
to be set, to get the right date and time for clock display, and all
Metering and Logging date and time stamp values.
To set the clock, select the clock setting in the “Setting Main”
display window. Configure the settings below to set the clock.
Date Mode:
Sets the mode for the date used in all time stamp displays.
Time Mode:
Sets the mode for the time used in all time stamp displays.
Choose 12 hour mode for AM and PM display of the time.
Choose 24 hour mode for military display. Example; 1 P.M. would
be displayed as 13:00.
Year:
Sets the current year for the real-time clock update.
Month:
Sets the current month for the real-time clock update.
Day:
Sets the current day for the real-time clock update.
Hour:
Sets the current hour for the real-time clock update.
Minute:
Sets the current minute for the real-time clock update.
Second:
Sets the current second for the real-time clock update.
Update Clock:
Pressing Enter updates the clock with the date and time specified
above, with the message stating that the real-time clock was
properly updated.
