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
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.
