Digistart D3: User Guide 101
Issue: G
Parameter settings:
• Pr 3A Input A Function
• Select 'Input Trip (N/O)'. Assigns the Input A to Auxiliary Trip (N/O) function.
• Pr 3B Input A Name
• Select a name, eg Low Pressure. Assigns a name to Input A.
• Pr 3C Input A Trip
• Set as required. For example, 'Run Only' limits the input trip to when the soft starter is running only.
• Pr 3E Input A Trip Delay
• Set as required. Sets a delay between the input activating and the soft starter tripping.
• Pr 3D Input A Initial Delay
• Set at around 120 seconds. Limits operation of the input trip to 120 seconds after the start signal.
This allows time for pressure to build up in the piping before the low pressure input becomes active.
