Chapter 11 Trouble shooting
11:1 General
This chapter is a guide that can be used in case problems
should arise with the softstarter or the application.
The softstarter normally indicates a fault with LED Fault, and
the LCD displays what type of fault it is. When a protection is
activated it will be indicated with LED Protection and the LCD
displays what type of protection is active.
Faults not displayed in the softstarter can also be found in
this chapter.
11:2 Overview of indications
This table shows in which state the different indications for
protections, faults, and warnings may show up.
