7.6 Inputs
3-1 Local/Remote
Option:
Function:
Selects when the [Auto On] and [Hand On]
buttons can be used to switch to Hand On or
Auto On modes.
Lcl/Rmt
anytime
*
The user can change between local and
remote control at any time.
Local Control
Only
All remote inputs are disabled.
Remote Control
Only
Selects whether the starter can be used in
Hand On or Auto On modes.
3-2 Comms in Remote
Option:
Function:
Selects whether the starter will accept Start
and Stop commands from the serial
communication network when in Remote
mode. The Force Comms Trip, Local/Remote
Control and Test Start and Reset commands
are always enabled.

3-3 Input A Function
Option:
Function:
Selects the function of Input A.
Motor Set
Select
*
The MCD 500 can be configured with two
separate sets of motor data. The primary motor
data is programmed using Parameters 1-1 to
1-16. The secondary motor data is programmed
using Parameters 7-1 to 7-16.
To use the secondary motor data, this parameter
must be set to
Motor Set Select
and 11, 16 must
be closed when a start command is given. The
MCD 500 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 this parameter is set to
Input Trip (N/O)
, a
closed circuit across 11, 16 trips the soft starter
(Parameters 3-5, 3-6, 3-7).
Input Trip
(N/C)
When this parameter is set to
Input Trip (N/C)
, an
open circuit across 11, 16 trips the soft starter
(Parameters 3-5, 3-6, 3-7).
Local/Remote
Select
Input A can be used to select between local and
remote control, instead of using the buttons on
theLCP. When the input is open, the starter is in
local mode and can be controlled via the LCP.
When the input is closed, the starter is in
remote mode. The [Hand On] and [Auto On]
buttons are disabled, and the soft starter will
3-3 Input A Function
Option:
Function:
ignore any Local/Remote select command from
the serial communications network.
To use Input A to select between local and
remote control,
3-1 Local/Remote
must be set to
LCL/RMT Anytime
.
Emergency
Run
In emergency run the soft starter continues to
run until stopped, ignoring all trips and
warnings (see
15-3 Emergency Run
for details).
Closing the circuit across 11, 16 activates
emergency run.
Opening the circuit ends emergency run and the
MCD 500 stops the motor.
Emergency
Stop
The MCD 500 can be commanded to emergency
stop the motor, ignoring the soft stop mode set
in
1-10 Stop Mode
.
When the circuit across 11, 16 is opened, the
soft starter allows the motor to coast to stop.
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).
3-4 Input A Name
Option:
Function:
Selects a message for the LCP to display
when Input A is active.

3-5 Input A Trip
Option:
Function:
Selects when an input trip can occur.
Always Active
*
A trip can occur at any time when the soft
starter is receiving power.
Operating Only A trip can occur while the soft starter is
running, stopping or starting.
Run Only
A trip can only occur while the soft starter is
running.
3-6 Input A Trip Delay
Range:
Function:
0 secs
*
[0:00 - 4:00 (min:secs)] Sets delay between the input
activating and soft starter
tripping.
