PROGRAMMING MENU
This function is ideal for remote installations using 2-wire control in Remote mode. If the 2-wire start signal is present after an
auto-reset, the EMX3 will restart.

6 Inputs
The EMX3 has two programmable inputs, which allow remote control of the soft starter. If required, two extra inputs are available
on the input/output expansion card.
6A – Input A Function
Options:
Motor Set Select (default)
The EMX3 can be configured with two separate sets of motor data.
To use the secondary motor data, parameter 6A must be set to 'Motor Set
Select' and C53, C54 must be closed when a start command is given. The
EMX3 checks which motor data to use at a start, and will use that motor data
for the entire start/stop cycle.
Input Trip (N/O)
Input A can be used to trip the soft starter. When parameter 6A is set to
Input Trip (N/O), a closed circuit across C53, C54 trips the soft starter.
Input Trip (N/C)
When parameter 6A is set to Input Trip (N/C), an open circuit across C53, C54
trips the soft starter.
Local/Remote Select
Input A can be used to select between local and remote control, instead of
using the LCL/RMT button on the keypad. When the input is open, the starter
is in local mode and can be controlled via the keypad. When the input is
closed, the starter is in remote mode. The START and LCL/RMT buttons are
disabled, and the soft starter will ignore any Local/Remote select command
from the serial communications network.
To use Input A to select between local and remote control, parameter 6Q must
be set to 'LCL/RMT Anytime' or 'LCL/RMT When Off'.
Emergency Run
In emergency run the soft starter continues to run until stopped, ignoring all
trips and warnings (refer to parameter 15C for details).
Closing the circuit across C53, C54 activates emergency run.
Opening the circuit ends emergency run and the EMX3 stops the motor.
Starter Disable
The EMX3 can be disabled via the control inputs. An open circuit across C53,
C54 will disable the starter. The EMX3 will not respond to start commands.
If running, the soft starter will allow the motor to coast to stop, ignoring the
soft stop mode set in parameter 2H.
Jog Forward
Activates jog operation in a forward direction (will operate only in Remote
mode).
Jog Reverse
Activates jog operation in reverse direction (will operate only in Remote mode).
