Protective Trip and Warning Functions
Table 256 - Under kW Warn Level (Parameter 381)
Over kW Trip
The E300 Electronic Overload Relay trips with an Over kW indication if:
•
No trip currently exists
•
Over kW Trip is enabled
•
Current is present
•
Voltage is present
•
Over kW Inhibit Time has expired
•
The total real power (kW) is greater than the Over kW Trip Level for a
time period greater than the Over kW Trip Delay.
If the E300 Electronic Overload Relay trips on an over real power (kW), the:
•
TRIP/WARN LED status indicator flashes a red 2-long / 2-short blink
pattern
•
Bit 1 in Power Trip Status (Parameter 6) sets to 1
•
Bit 0 in Device Status 0 (Parameter 20) sets to 1
•
Any relay outputs configured as a Trip Relay open
•
Any relay outputs configured as a Control Relay open
•
Any relay outputs configured as a Trip Alarm close
•
Any relay outputs configured as a Normal Relay are placed in their
Protection Fault state (if so programmed)
