S611 Fault Codes, continued

Note:

All mains and control power connections must be completed and voltage applied prior
to a START command. Failure to make all connections will result in one or more faults.

All isolation and/or reversing contactors must be staged prior to any START commands.
Manipulating contactors after the START command will result in one or more faults.

Code

Fault

Condition

Solution

Voltage Phase Imbalance

•

The voltage imbalance of the incoming
phases exceeds the trip threshold

•

Correct imbalance problem with mains

•

Increase the

Voltage Fault Imbalance

parameters

•

Disable the fault if the other issues cannot be resolved

Note:

Phase imbalance may be impacted by voltage issues and/or current issues.
Voltage imbalance trip threshold range is 1–100% (default 6%). Voltage imbalance trip delay range is 0–60 seconds (default 10 seconds).
Voltage phase imbalance protections may be disabled (not recommended).

Note:

Phase loss is a severe condition of phase imbalance, even momentarily. In cases of severe imbalance causing nuisance trips, this feature may be disabled
(not recommended). Prior to disabling this protection, adjust the

Phase Loss %

trip parameter value (default is 80%) to see if it will improve the condition.

Adjusting the

Phase Loss Delay

(default is 0.5 seconds) may also improve performance in cases where phase instability is a problem. Phase performance

should be monitored for an appropriate length of time to ensure that the phase is not dropping just long enough for the soft starter to detect the condition.

Jam

•

Soft starter in bypass: Motor below rated
RPM and/or current exceeds 3 x motor
FLA

•

Remove obstruction

•

Verify proper FLA setting in Operation mode

•

Jam fault can be disabled if trips occur during normal
operation (Overcurrent fault will provide protection at
a higher current threshold of 4 x catalog FLA)

Note:

The jam fault may be disabled (not recommended). The maximum rms value of the three-phase currents is monitored when the internal bypass
contactors are closed.
The jam fault trip threshold range is 150–400% of motor FLA. Jam trip delay range is 1–20 seconds (default is 2.0 seconds).

Contactor Overcurrent

•

Only active in bypass if the jam fault is
disabled

•

Current exceeds the fault threshold of
4 x catalog FLA

•

Remove obstruction in motor drive train

•

Verify S611 is properly sized for the application

Note:

This feature is active only with the

Jam Fault

trip parameter disabled, and the internal bypass contactor(s) are closed. This results in a higher current trip

threshold in most cases. Monitors the maximum rms value of the three-phase current and is not user settable. Catalog FLA refers to the maximum
continuous line current capacity of the frame size of the S611, NOT the motor rated FLA. At 4 x FLA, the following approximate trip delay times are; Class
5 = 4.5 seconds, Class 10 = 9.0 seconds, Class 20 = 16.0 seconds, Class 30 = 23.0 seconds. Do not confuse this parameter with Instantaneous Overcurrent
(FC19), Thermal Overload (FC20), or SCR Overcurrent (FC27).

Missing Temp Sensor

•

Temperature sensor failure

•

Internal connection failure

•

Internal hardware failure (sensor and/or cable)

•

Note:

Disabling this feature (

Temp Sense

fault in

Protection

menu) will remove protection from

excessive temperature exposure (not recommended)

•

Not field repairable, contact Eaton Support

Note:

There are three (3) independent temperature sensors that incorporate a current sensor on each power pole (phase). This fault may be generated by any
one of the sensors. Temperature and/or current values observed in the

display should be within ±5% of each other. Verify that the values of all phases

are approximately equal. Sensors are calibrated to the printed circuit board (PCB) during manufacture and are not field serviceable. The

Device Temp

value shown in the

display monitors a sensor mounted directly on the PCB and is not related to any Temperature Sensor fault. Contact EatonCare for

service.

Cannot RESET fault

•

Fault condition still exists

•

Soft starter has not received RESET
signal
