nonvolatile storage or if it becomes corrupt. The Nonvolatile Storage Fault Trip is
always enabled.
The E300 relay trips with a hardware fault trip indication if:
• No trip currently exists
• Nonvolatile Storage Fault Trip is enabled
• An issue exists in the E300 relay’s nonvolatile storage
If
the E300 relay trips on a nonvolatile storage fault trip, the following occurs:
• The TRIP/WARN LED flashes a red 3-long / 14-short blink pattern
• Bit 13 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

Test Mode Trip
Some motor control center enclosures include a Test Position in which the motor
power is disconnected from the enclosure, but the control power is still active.
This allows motor control center commissioning staff to verify that the motor
starter is mechanically working and communication is established with the
automation control system. The E300 relay provides the capability to put the
The Protection Fault State of Relay 0, Relay 1, Relay 2, Digital Module 1 Output
Relays, Digital Module 2 Output Relays, Digital Module 3 Output Relays, and

• Output Digital Module 2 Protection Fault Action (Parameter 328)
• Output Digital Module 2 Protection Fault Value (Parameter 329)
• Output Digital Module 3 Protection Fault Action (Parameter 334)
• Output Digital Module 3 Protection Fault Value (Parameter 335)
• Output Digital Module 4 Protection Fault Action (Parameter 340)
• Output Digital Module 4 Protection Fault Value (Parameter 342)
