1.

Use and basic operation

The KEA 291 NSTR automatic system is used in 

emergency power systems

The function of the output relays and the parameters can be set with a PC. 

Because the KEA 291 has the same dimensions and fastenings as its predecessor, 

replacement

 is 

simple. 

Ten parameterisable alarm and operating indicators 

– which can be labelled by easily 

replaceable paper strips 

– as well as 

four

 

general displays 

are displayed through LEDs. The pa-

rameterisation can be performed using the 

serial USB interface

 with the 

P

ARA

W

IN 

parameterisation 

program. 

Important note!

 

The operation of the automatic system is simple and uncomplicated as it is carried out via the usual 
buttons 

– without menu guidance – as for all previous automatic systems.
