Issue: G
8.8.5 Group 4 - Digital Outputs
The Digistart D3 has three programmable outputs, which can be used to signal different operating conditions to
associated equipment. Three additional outputs are available on the input/output expansion card.
4A - Relay A Action
Options:
Off Relay A is not used.
Main Contactor (default) The relay closes when the Digistart D3 receives a start command,
and remains closed as long as the motor is receiving voltage.
Run The relay closes when the starter changes to run state.
Trip The relay closes when the starter trips (see Pr 16A to 16X).
Warning The relay closes when the starter issues a warning (see Pr 16A to
16X).
Low Current Flag The relay closes when the low current flag activates while the motor
is running (see Pr 7A Low Current Flag ).
High Current Flag The relay closes when the high current flag activates while the motor
is running (see Pr 7B High Current Flag ).
Motor Temperature Flag The relay closes when the motor temperature flag activates (see Pr
7C Motor Temperature Flag ).
Input A Trip The relay closes when Input A activates to trip the soft starter.
Input B Trip The relay closes when Input B activates to trip the soft starter.
Motor Overload The relay closes when the starter trips on Motor Overload.
Current Imbalance The relay closes when the starter trips on Current Imbalance.
Underpower The relay closes when the starter trips on Underpower.
Overpower The relay closes when the starter trips on Overpower.
Frequency The relay closes when the starter trips on Frequency.
Ground Fault The relay closes when the starter trips on Ground Fault.
Heatsink Overtemperature The relay closes when the starter trips on Heatsink Overtemperature.
Phase Loss The relay closes when the starter trips on Phase Loss.
Motor Thermistor The relay closes when the starter trips on Motor Thermistor.
Changeover Contactor The relay closes when the high rotor resistance current ramp has
reached full voltage, allowing use with a slip-ring motor.
Description:
Selects the function of Relay A (normally open). Relay A is terminals COM1, RLO1.
4B – Relay A On Delay
Range:
0:00 - 5:00 (minutes:seconds) Default: 0 second
Description:
Sets the delay for closing Relay A.
4C – Relay A Off Delay
Range:
0:00 - 5:00 (minutes:seconds) Default: 0 second
Description: Sets the delay for re-opening Relay A.
4D - Relay B Action
Options:
Off Motor overload
Main Contactor Current imbalance
Run (default) Underpower
Trip Overpower
Warning Frequency
Low Current Flag Ground fault
High Current Flag Heatsink overtemperature
Motor Temperature Flag Phase Loss
Input A trip Motor thermistor
Input B trip Changeover Contactor
Description: Selects the function of Relay B. Relay B is a changeover relay. See Pr 4A Relay A Action for
details.
