8.8.4 Group 3 - Digital Inputs
The Digistart D3 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.
3A – Input A Function
Options:
Motor Set Select
The Digistart D3 can be configured with two separate sets of motor
data.
To use the secondary motor data, Pr 3A must be set to 'Motor Set
Select' and DI4, +24V must be closed when a start command is
given. The Digistart D3 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 Pr 3A is set to Input
Trip (N/O), a closed circuit across DI4, +24V trips the soft starter.
Input Trip (N/C)
When Pr 3A is set to Input Trip (N/C), an open circuit across DI4,
+24V 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, Pr 3M
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 (see Pr 15B for details).
Closing the circuit across DI4, +24V activates emergency run.
Opening the circuit ends emergency run and the Digistart D3 stops
the motor.
Starter Disable (default)
The Digistart D3 can be disabled via the control inputs. An open
circuit across DI4, +24V will disable the starter. The Digistart D3 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 Pr 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).
Description: Selects the function of Input A.
3B – Input A Name
Options: Input Trip No Flow
Low Pressure Starter Disable (default)
High Pressure Controller
Pump Fault PLC
Low Level Vibration
High Level
Description: Selects a message for the keypad to display when Input A is active.
3C – Input A Trip
Options:
Always Active (default)
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.
Description: Selects when an input trip can occur.
3D – Input A Initial Delay
Range: 00:00 - 30:00 (minutes:seconds) Default: 0 second
Description: Sets a delay before an input trip can occur. The initial delay is counted from the time a start signal
is received. The state of the input is ignored until the initial delay has elapsed.
