Under kW Inhibit Time
Under kW Inhibit Time (Parameter 378) allows you to inhibit an under real
power (kW) trip and warning from occurring during the motor starting
sequence. It is adjustable from 0…250 seconds.
Table 317 - Under kW Inhibit Time (Parameter 378)
Over kW Inhibit Time
Over kW Inhibit Time (Parameter 382) allows you to inhibit an over real power
(kW) trip and warning from occurring during the motor starting sequence. It is
adjustable from 0…250 seconds.
Table 318 - Over kW Inhibit Time (Parameter 382)
Under kW Trip
The E300 relay trips with an Under kW indication if:
• No trip currently exists
• Under kW Trip is enabled
• Current is present
• Voltage is present
• Under kW Inhibit Time has expired
• The total real power (kW) is less than the Under kW Trip Level for a time
p
erio
d greater than the Under kW Trip Delay.
If the E300 relay trips on an under real power (kW), the:
• T
RIP/WARN LED status indicator flashes a red 2-long / 1-short blink
patter
n
• Bit 0 in Power Trip Status (Parameter 6) sets to 1
• Bit 0 in Device Status 0 (Parameter 20) sets to 1
