2.9 Control Wiring
1) The programmed digital input settings for D1COM , D1-1I, D1-2I, and D2COM , D2-1I must correspond
to the voltage applied to these terminals to avoid risk of damage to the equipment.
2) The control supply can be 110 to 230VAC applied to the N, L terminals or 24VDC applied to the 0VDC,
24V input terminals. The correct voltage as specified must only be applied to one of these supply inputs
to avoid risk of damage to the equipment.
2.9.1 Three Wire Control
Power factor correction capacitors* must not be positioned between the soft starter and the motor, or
there is a risk of damaging the thyristors due to current peaks.
2.9.2 User Programmable Control
1) Optional high reset. If this reset is required, ensure that “User Programmable” is selected as the control method menu
found in the Digital Inputs menu. If you would prefer the reset to work by removing and reapplying the Start Signal on
D1-1I then select “Two wire control” in the control method menu.
Digital Input Configuration Digital Output Configuration
D1-1I = High Start / Low Stop 34 = DO3 set to “Running”
(This pulls in the line contactor,
K1, before the ramp starts) D1-2I = None
D2-1I = High Reset
