General Information
S801+ Soft Starter MN03900002E—November 2012 www.eaton.com 49
11
Overload Fault Motor overloaded for an extended period of
time.
Reduce the motor’s load.
Thermal Memory is over 100% Verify the Overld Trip FLA and/or Ovrld Trip Class for proper
adjustment.
Note: Exceeding nameplate ratings will shorten equipment life.
Fault during motor start: Verify system is not exceeding the specified
maximum starts per hour.
Increase the initial torque and/or reduce ramp time to bring the motor
up to speed faster.
Increase Trip Class setting (30 maximum) and/or reduce ramp time
setting.
Notes:
Higher than normal thermal memory may indicate an abnormal operating condition and signal an impending Overload fault.
12
Motor Stall Motor not at rated RPM at end of start ramp
time and/or current is in excess of 2X FLA.
Lengthen Soft Start Time and/or increase Initial Torque
potentiometers
Bypass contactors not closed at the end of
the start time (start current low/ramp time
short).
Loads that are heavily loaded (high inertia) during a start such as fans
will often need an initial torque setting much greater than the factory
default.
Set Kick Start parameters.
Notes:
Motor rpm is monitored for a synchronous speed condition. A Motor Stall fault will occur at the end of the ramp time (default is 20 seconds) if the
motor is not at synchronous speed and the current is in excess of 2X FLA. This feature is not user settable. Verify that the motor is properly sized
for the load.
13
Jam Soft Starter in Bypass: Motor below rated
RPM and/or current exceeds 3X FLA.
Remove obstruction.
Verify proper FLA setting in Protections Menu.
Jam Fault can be disabled if trips occur during normal operation (Over
Current Fault will provide protection at a higher current threshold of
4X catalog FLA).
Notes:
The Jam Fault may be disabled (not recommended). The maximum RMS value of the 3 phase currents is monitored when the internal bypass
contactors are closed.
The Jam Fault Trip threshold is 3X Motor FLA and is not user settable.
14
Motor Voltage Phase
Reversal
Incoming line phase rotation sequence
opposite of device setting.
Exchange two incoming mains phases.
One phase missing and/or open fuse or
breaker.
Verify that all circuit breakers are closed or fuses are serviceable.
Notes:
If mains leads need to be changed, swap incoming leads and set Phase Sequence to match incoming sequence. If an upstream reverser is used,
disable Phase Rev Fault (not recommended). This fault is not uncommon in new installations. In the event of a blown fuse prior to a START
command, this fault may occur as the unit is not able to determine phase rotation with one open fuse. If motor rotation requires exchange of
phases, exchange the cables between the soft starter and the motor.
