Protective Trip and Warning Functions Chapter 6
Preventive Maintenance
The E300 Electronic Overload Relay offers preventive maintenance warnings
based on the number of start cycles and the number of operating hours. These
warnings can be used to alert you that the number of starts or number of
operating hours has been reached, and it is time to perform preventive
maintenance.
Number of Starts Warning
The E300 Electronic Overload Relay warns with a number of starts warning
indication if:
• No warning currently exists
• Number of Starts Warning is enabled
• The value in Starts Counter (Parameter 29) is greater than the value set in
Total Starts (Parameter 207)
If the E300 Electronic Overload Relay warns on a number of starts warning, the
following occurs:
• The TRIP/WARN LED flashes a red 3-long / 12-short blink pattern
• Bit 11 in Control Warning Status (Parameter 13) sets to 1
• Bit 1 in Device Status 0 (Parameter 20) sets to 1
• Any relay outputs configured as a Warning Alarm close
Total Starts
Total Starts (Parameter 207) allows you to set the number starts until the starts
counter warning occurs.
