Main Contactor
Selects the function of Relay A (normally open). Relay A is terminals COM1, RLO1.
Off
Relay A is not used.
Main Contactor
The relay closes when the Digistart IS 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 (see Pr 7A
Low Current Flag, while the motor is running).
High Current Flag
The relay closes when the high current flag activates (see Pr 7B
High Current Flag, while the motor is running).
Motor Temp 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 Overtemp
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.
