Appendix B—Protection

Thermal Overload

The S811+ Soft Starter features an electronic motor overload
protection feature. This is intended to protect the motor and
power wiring against overheating caused by excessive
current for extended periods of time.

Note: Short circuit protection must be applied on the

line side of the soft starter.

Enter the motor full load current rating, using the

Mtr

Nameplate FLA

parameter in the Soft Start Config Menu to

program the trip current. It is programmable from 32–100%
of the unit’s rated current.

Overload—Adjustment Range—Inline Connected

Overload—Adjustment Range—Inside-the-Delta
Connected

Note:

Mtr Nameplate FLA

parameter is adjustable to any

point within its range.

The thermal overload is designed to protect the motor from
overheating caused by excessive current. If the motor is
overloaded, the current drawn rises and heats the motor. The
FLA sets the trip threshold and the trip class (5 to 30) is set
with the

Ovrld Trip Class

parameter.

If the device trips on a thermal overload, an internal timer is
started which inhibits a reset for three minutes. After this
timer expires, the device may be reset and the thermal fault
is cleared. At this point another internal timer is started, this
timer is 26 x 3 or 48 minutes. If another trip occurs before
this timer expires, the reset inhibit time is increased to
6 minutes.
