4.1 PS D75.. 840 without built-in electronic overload protection
LED's
F1: (red) Fault signal for Phase loss, Thyristor fault, High current switch off.
F2: (red) Fault signal for Over temperature, Fault on circuit board, Thyristor fault
On: (green) Supply voltage. Illuminates when softstarter has control power.
R: (yellow) Motor is running. Illuminates when the motor is energised from the softstarter.
T: (yellow) Top of ramp. Start ramp is finished and stop ramp hasn't begun.
P: (yellow) Energy saving is active
