OPERATION
C
CAUTION
We recommend testing the soft starter's setup on a low voltage motor before beginning operation on a
medium voltage motor. This allows the operator to test that the soft starter is correctly connected to
the auxiliary equipment.
12.1
Start, Stop and Reset Commands
The soft starter can be controlled in three ways:
using the buttons on the controller
via remote inputs
via a serial communication link
The LLCL/RMT button controls whether the MVS will respond to local control (via the controller) or remote control
(via the remote inputs).
The Local LED on the controller is on when the soft starter is in local control mode and off when the soft starter is
in remote control mode.
Control via the fieldbus communication network is always enabled in local control mode, and can be enabled or
disabled in remote control mode (parameter 6R
Comms in Remote). Control via the serial communication
network requires an optional communication module.
The SSTOP button on the controller is always enabled.
12.2
Using the Soft Starter to Control a Motor
To soft start the motor, press the SSTART button on the controller or activate the Start remote input. The motor
will start using the start mode selected in parameter 2A.
To stop the motor, press the SSTOP button on the controller or activate the Stop remote input. The motor will
stop using the stop mode selected in parameter 2H.
To reset a trip on the soft starter, press the R
RESET button on the controller or activate the Reset remote input.
To stop the motor with a coast to stop, regardless of the setting of parameter 2H
Stop Mode, press the local SSTOP
and RESET buttons at the same time. The soft starter will remove power from the motor and open the main
contactor, and the motor will coast to stop.
