The factory settings for DS7-34… soft starters are configured in such a way
as to allow a suitably rated 4-pole standard motor to be run in typical soft
starter applications without the need for any additional adjustments.
In addition, soft starters belonging to the DS7-34D… series also feature a
1-0-A switch that can be used to manually switch the soft starter on and off.
The 1-0-A switch’s positions have the following functions:
• 1: DS7-SWD = ON
• 0: DS7-SWD = OFF
• A: Control via SmartWire-DT (PNU 928.0) or via control signal terminals /
potentiometers
The 1-0-A switch can be used for starting and stopping the motor only if soft
starter DS7-34D... is supplied with 24 V DC through the SmartWire-DT ribbon
cable or the control signal terminals U
