Chapter 10 Troubleshooting

10.1 General

This chapter is a guide that can be used in case problems should arise with the
PSE Softstarter or the application.
The PSE Softstarter normally indicates a fault with LED Fault status indicator, and
the LCD displays type of fault. When a protection is activated, it will be indicated
with the LED protection status indicator, and the LCD displays what type of
protection is active. More information about LEDs and LCD display is available in
chapters 6.1.2.1 and 6.1.2.2.
Faults not displayed on the PSE Softstarter Human Machine Interface can also be
found in this chapter.
