Troubleshooting Chapter 10
Non-Volatile Storage
Fault
1. Firmware Downgrade corrupted: Non-volatile
memory 1.Execute the Clear Command to the operating
Statistics, History Logs, and % TCU
2. Internal product failure 2. Consult the factory.
Hardware Fault
1. Firmware of sensing module is not
compatible with control module firmware
1. Verify firmware revisions of control module
and sensing module
2. Upgrade firmware of control module to v2.0
or higher
2. Hardware configuration failure
3. Consult the factory.
4. Verify that the Sensing, Control, and
Communication Module are connected properly.
5. Verify that connection pins between sensing
module and control module are not bent.
Configuration Fault
1. Single/Three Phase (Parameter 176) is set to
"Single Phase" and current is being sensed in
phase L3 during motor operation.
1. For three-phase applications, Single/Three
Phase (Parameter 176) should be set to “Three-
Phase”; for single-phase applications, verify
that current is flowing through L1 and L2 only.
2. Operating Mode "Overload (Network)" does
not have an assigned Trip Relay
2. Verify that one of the Output Assignments
(Parameters 202-204) is configured as a "Trip
Relay"
3. Illegal configuration value
3. Review Invalid Configuration Parameter
(Parameter 38) and Invalid Configuration Cause
(Parameter 39) to identify which configuration
parameter is illegal and the reason why.
Remote Trip
1. Contact closure of remote sensor (e.g.,
vibration switch).
1. Take corrective action to address the issue
that caused the sensor to actuate.
2. Check sensor for proper operation.
3. Check wiring.
Total Starts Warning
1. Starts Counter (Parameter 29) is equal to or
greater than the value set in Total Starts
(Parameter 207) 1. Set Clear Command (Parameter 165) to "Clear
Operating Statistics" to reset Starts Counter
(Parameter 29)
Total Operating
Hours Warning
1. Operating Time (Parameter 28) is equal to or
greater than the value set in Total Operating
Hours (Parameter 208) 1. Clear Command (Parameter 165) to "Clear
Operating Statistics" to reset Operating Time
(Parameter 28)
Blocked Start
1. The number of starts count within the past
hour period equals the value set in the Starts
Per Hour (Parameter 205) 1. Check Time to Start (Parameter 31) and wait
that amount of time, or change the
configuration to allow more starts/hour.
2. The time expired since the most recent start is
less than the value set in the Starts Interval
(Parameter 206)
2. Check Time to Start (Parameter 31) and wait
that amount of time, or change the
configuration to shorten the interval between
starts.
