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.
To use the starter disable function, set Pr 3A to 'Starter Disable' (this is the default setting).
If the Starter Disable function is not required, change the setting of Pr 3A or connect a link across DI4, +24V.
For keypad control, the soft starter requires:
•
control supply connections (terminals CSH, CSL, CSR depending on the control voltage)
•
programmable input A (DI4, +24V) must be closed or Pr 3A
Input A Function
must be changed from Starter
Disable
