Table 333 - Analog Module 2 – Channel 02 Warning Level (Parameter 494)
Analog Module 3
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 3 – Channel 00 Over Level Trip
The E300 Electronic Overload Relay trips with an Analog Module 3 – Channel
00 Over Level Trip indication if:
• No trip currently exists
• Analog Module 3 – Channel 00 Over Level Trip is enabled
• The measured analog input signal is greater than the Analog Module 3 –
Channel 00 Trip Level for a time period greater than the Analog Module 3
– Channel 00 Over Level Trip Delay.
If the E300 Electronic Overload Relay trips on an Analog Module 3 – Channel
00 Over Level, the:
• TRIP/WARN LED status indicator flashes a red 4-long / 7-short blink
pattern
• Bit 6 in Analog Trip Status (Parameter 8) 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)
