Power Voltage Supply Test
There is no specific test procedure to check the
condition of the soft starter control voltage supply.
•
If the Ready LED (Red) is off, verify that correct
control voltage is connected to the correct control
voltage input terminals.
On CV1 models, A1 to A2 voltage must be 24 V
AC or DC (+20%/-20%).On CV3 models A1 to A2
voltage must be 110 V AC to 240 V AC (+10%/-
15%) or A2 to A3 voltage must be 380 V AC to
440 V AC (+10%/-15%).
•
If the Ready LED (Red) remains off, the Main PCB
is damaged and must be replaced.
