6 Inputs
The MVS has two programmable inputs, which allow remote control of the soft starter.
6A – Input A Function
Options:
Motor Set Select
The MVS 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 MVS 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) (default)
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.
(Refer to parameters 6C, 6D, 6E)
Input Trip (N/C)
When parameter 6A is set to Input Trip (N/C), an open
circuit across C53, C54 trips the soft starter.
(Refer to parameters 6C, 6D, 6E)
Local/Remote Select
Input A can be used to select between local and remote
control, instead of using the LLCL/RMT button on the
controller. When the input is open, the starter is in local
mode and can be controlled via the controller. When the
input is closed, the starter is in remote mode. The
START and LLCL/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 MVS
stops the motor.
