Table 407 - Analog Module 3 – Channel 02 Warning Level (Parameter 525)
Analog Module 4
The E300 Analog I/O Expansion Module scans up to three analog signals. An
over level trip or warning can be configured for each input channel.
Analog Module 4 – Channel 00 Over Level Trip
The E300 relay trips with an Analog Module 4 – Channel 00 Over Level Trip
indication if:
• No trip currently exists
• Analog Module 4 – Channel 00 Over Level Trip is enabled
• The measured analog input signal is greater than the Analog Module 4 –
C
ha
nnel 00 Trip Level for a time period greater than the Analog Module 4
– Channel 00 Over Level Trip Delay.
If the E300 relay trips on an Analog Module 4 – Channel 00 Over Level, the:
• TRIP/WARN LED status indicator flashes a red 4-long / 10-short blink
