4.1.4 Start/Stop control logic The Digistart D3 has three fixed inputs for remote control. These inputs should be controlled by contacts rated for low voltage, low current operation (gold flash or similar). The maximum cable run is determined by the type of cable used, provided the maximum resistance of this cable does not exceed 100 Ohms.
Data NOTE If no motor thermistors are connected to the Digistart D3 thermistor input terminals TH1, TH2 must be open. If TH1, TH2 are shorted, the Digistart D3 will trip. The thermistor circuit should be run in screened cable and must be electrically isolated from ground and all other power and control circuits.
Motor connection Digistart D3 soft starters can be connected to the motor in-line or inside delta (also called three-wire and six-wire connection). The Digistart D3 will automatically detect the motor connection and perform the necessary calculations internally, so it is only necessary to program the motor full load current (Pr 1A).
Page 19
In-line installation, externally bypassed Non-bypassed models have dedicated bypass terminals, which allow the Digistart D3 to continue providing protection and monitoring functions even when bypassed via an external bypass contactor. The bypass contactor must be connected to the bypass terminals and controlled by the soft starter's run output (terminals COM2, RLO2).

SCRs from transient overload currents. HRC fuses (such as Ferraz AJT fuses) can be used for Type 1 coordination according to IEC 60947-4-2 standard. Fuses are not delivered with Digistart D3 soft starters. NOTE Adaptive Control controls the motor's speed profile, within the programmed time limit. This may result in a higher level of current than traditional control methods.

The Ready LED activates Program parameters The Quick Setup Menu makes it easy to configure the Digistart D3 for common applications. The Digistart D3 selects the parameters relevant to the application and suggests a typical setting, and you can adjust each parameter to suit your exact requirements.
The Remote LED on the Digistart D3 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.
Adaptive control for starting Adaptive Acceleration Control is a new intelligent motor control technique. In an adaptive control soft start, the Digistart D3 adjusts the current in order to start the motor within a specified time and using a selected acceleration profile.
Adaptive control for stopping In an adaptive control soft stop, the Digistart D3 controls the current in order to stop the motor within a specified time and using a selected deceleration profile. Adaptive Deceleration Control can be useful in extending the stopping time of low inertia loads.
Counters The Counters Menu provides access to information on the starter's operating history. For full details of the advanced menu, setup tools, simulations, I/O state, and logs and counters, see the Digistart D3 User Guide available on the supplied CD.

Related Pr: None Time - Overcurrent The Digistart D3 is internally bypassed and has drawn high current during running. (The 10A protection curve trip has been reached or the motor current has risen to 600% of the motor FLC setting.)
The emergency stop function may be active. If Pr 3A or 3F is set to Emergency Stop and there is an open circuit on the corresponding input, the Digistart D3 will not start. If the emergency stop situation has been resolved, close the circuit on the input.
