Protective Trip and Warning Functions Chapter 6
Table 303 - Control Warning Status (Parameter 13)
Test Trip
The E300 Electronic Overload Relay provides the capability to put the overload
relay into a Test Trip state. You can implement this feature when commissioning a
motor control circuit to verify the response of the E300 Electronic Overload
Relay, its associated Expansion I/O modules, and the networked automation
system.
The E300 Electronic Overload Relay trips with a test trip indication if:
• No trip currently exists
• Test Trip protection is enabled
• You press the blue reset button on the Communication Module for more
than 3 seconds.
If the E300 Electronic Overload Relay trips on a test trip, the following occurs:
• The TRIP/WARN LED flashes a red 3-long / 1-short blink pattern
• Bit 0 in Control Trip Status (Parameter 7) 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)
