Expansion Bus Trip
Expansion Bus Trip is enabled by setting Control Trip Enable (Parameter 186)
bit 10 to 1. When communications is disrupted between the Control Module
and digital and/or analog expansion I/O modules, the E300 Electronic Overload
Relay will go into a tripped state in which the Trip/Warn LED on the
Communication Module and Operator station will blink a red 3 long and 11
short blinking pattern.
Table 49 - Expansion Bus Trip Bit Function Detail— Control Trip Enable (Parameter 186)
To return to Operation/Run Mode, verify that the expansion bus cables are
properly plugged into the Bus In and Bus Out ports of all of the expansion
modules. When all of the expansion I/O modules’ status LEDs are solid green,
reset the trip state of the E300 Electronic Overload Relay by pressing the blue
reset button on the Communication Module, via network communications, with
the internal web server of the EtherNet/IP communications module, or by an
assigned digital input.
