Failure Type Failure Description Corrective Action
Input 1, 2 Input 1 or 2 does not appear
to recognize a contact
closure 1. Check the supply voltage on the power connector.
2. If the applicable contact closed but the E1 Plus EtherNet/IP Module Input does not
recognize the closure, check the continuity and wiring to the connected contact.
3. Check the IN 1 and 2 status LEDs. If the appropriate LED does not illuminate, measure the voltage
across and current through the applicable input. Verify they are within the ratings of the E1 Plus
EtherNet/IP Module (See Appendix A).
4. If the appropriate Input LED does illuminate, but the input status is not reported properly over the
EtherNet/IP network, check the programmable controller ladder logic and I/O mapping.
Input 1, 2 Trip reset operation Check the programming of Parameter 40, IN1 Assignment or Parameter 41, IN2 Assignment.
OUT A Output A does not appear to
turn on (close) when
commanded to do so. 1. Check the supply voltage on the power connector.
2. Check the OUTA status LED. If the appropriate LED does not illuminate, check the programmable
controller ladder logic and I/O mapping.
3. If the appropriate Output LED is illuminated, remove the control circuit power and check for
continuity across the appropriate output terminals (13/14). If the continuity test indicates the
output is open, replace the E1 Plus
EtherNet/IP Module. Check the supply voltage against
the ratings of the contactor and the relay output before installing a new unit.
4. Remove control circuit power and check the control circuit fuse and the control wiring to the E1
Plus EtherNet/IP Module output terminals.
5. Check the control circuit power supply. Verify the voltage is within the contactor and overload
relay ratings.
6. Check the DEVICE STATUS and TRIP STATUS parameters. If a Protection Fault exists, refer to the
TRIP STATUS parameters. If a EtherNet/IP -related fault exists, refer to the EtherNet/IP
troubleshooting procedure.
7. Check the OUTA Pr FltState, Pr FltValue, En FltState, En FltValue, En IdlState, and En IdlValue
programmable parameters. The Pr FltState and Pr FltValue parameter supersede the En Flt or En
Idle parameters.
OUT A Output A does not appear to
turn off (open) when
commanded to do so. 1. Check the OUTA status LED. If the appropriate LED remains illuminated, check the programmable
controller ladder logic and I/O mapping.
2. If the appropriate Output LED is not illuminated, remove the control circuit power and check for
continuity across the appropriate output terminals (13/14). If the continuity test indicates the
output is closed, replace the E1 Plus
EtherNet/IP Module. Check the supply voltage against
ratings of the contactor and the relay output before installing a new unit.
3. Remove control circuit power and check the control circuit fuse and the control wiring to the E1
Plus EtherNet/IP Module output terminals.
4. Check the OUTA Pr FltState, Pr FltValue, En FltState, En FltValue, En IdlState, and En IdlValue
programmable parameters. Then check the DEVICE STATUS and TRIP STATUS parameters. If a
Protection Fault exists, refer to the TRIP STATUS parameters. If a
EtherNet/IP -related fault
exists, refer to the EtherNet troubleshooting procedure.
OUT A The contactor connected to
Output A appears to
“chatter” 1. Verify the OUT A LED remains in the appropriate On or Off state. If the LED is flickering, check the
programmable controller’s ladder logic program.
2. Check the control circuit supply voltage. Verify it is within the ratings of the contactor coil and the
overload relay’s outputs.
3. Remove the control circuit power. Verify all control wiring is properly secured.
