condition must be present before a trip occurs. It is adjustable from 0.1…25.0
seconds.
Table 343 - Analog Module 4 – Channel 00 Over Level Trip Delay (Parameter 536)
Analog Module 4 – Channel 00 Trip Level
Analog Module 4 – Channel 00 Trip Level (Parameter 537) allows you to define
the magnitude of the analog signal in which the E300 Electronic Overload Relay
trips on an Analog Module 4 – Channel 00 Over Level trip. It is user-adjustable
from -32768…+32767.
Table 344 - Analog Module 4 – Channel 00 Trip Level (Parameter 537)
Analog Module 4 – Channel 00 Over Level Warning
The E300 Electronic Overload Relay indicates an Analog Module 4 – Channel
00 Over Level warning if:
• No warning currently exists
• Analog Module 4 – Channel 00 Over Level Warning is enabled
• The maximum phase current is equal to or greater than the Analog
Module 3 – Channel 00 Warning Level
When the Analog Module 3 – Channel 00 Over Level Warning conditions are
satisfied, the:
• TRIP/WARN LED flashes a yellow 4-long / 10-short blink pattern
• Bit 9 in Analog Warning Status (Parameter 14) sets to 1
• Bit 1 in Device Status 0 (Parameter 20) sets to 1
• Any relay outputs configured as a Warning Alarm closes
