Start, Stop and Reset Commands
The soft starter can be controlled in three ways:
•
using the buttons on the keypad
•
via remote inputs
•
via a serial communication link
The LCL/RMT button controls whether the EMX3 will respond to local control (via the keypad) or remote control (via the remote
inputs).
•
The Local LED on the keypad is on when the soft starter is in local control mode and off when the soft starter is in
remote control mode.
•
The Remote LED on the EMX3 is on when the soft starter is in Remote mode and off when in Local mode. The
Remote LED is located on the main body of the starter (behind the keypad) and is only visible if the keypad is remotely
mounted.
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

communication module.
The STOP button on the keypad is always enabled.

mode, the starter will ignore any auto-start/stop setting. To configure auto-start/stop operation, use parameters 3A~3D.
