DS6 series soft start controllers
24 Vdc power supply requirements
The 24 Vdc power supply for your DS6 soft start controller must
meet or exceed the following requirements:
•
•
•
•
Operations
•
•
•
•
N
It is important to correctly set the ramp time, so the bypass contactors will
close within 5 seconds after the motor has achieved rated RPM.

ote:
Minimum steady-state current: 1W (35 mA)
Minimum start command current: 2W (65 mA)
Minimum bypass contactor inrush current: 600 mA for 50 ms
Voltage stability: 24 Vdc +10%/–15%
24 Vdc control voltage is applied to terminal +24
The status light will illuminate after the starter has completed
initialization, closing contacts 23/24, and indicating READY status
Line voltage is applied to the starter by closing the
mains contactor
The soft start controller issues a START command by applying
+24 Vdc to terminals EN and +A1. Contacts 13 and 14 will close
when the end of the ramp time is reached
To initiate a STOP command, remove +24 Vdc from terminal EN
and +A1 or EN
To initiate a RAMP STOP command, remove +24 Vdc from
terminal +A1
Bypass contactors close at the end of ramp time + ~0.18 seconds.
Adjusting the soft start controller parameters
There are three adjustments to the DS6 soft start controller:
•
•
•
N
START command is sent to the soft start controller.
