3.3 Indication outputs.
The power supply unit is equipped with indication outputs informing about the power supply shortage
and failures.
•
AW – failure output: output (OC type) informing about the failures of the power supply unit
In the normal state, when there is no failures, the output is closed and it opens if a failure occurs.
•
BS- Power supply 230 VAC shortage output : output (OC type) informing about the
shortageof power supply 230 VAC in the normal mode, during the operation from 230 VAC the output
RED LED
•
blinking- indication of failure conditions ( Tab.1)
GREEN LED
•
lit- power supply unit operated from 230 V/AC, normal
operation
•
blinking- shortage of power supply 230 V/AC, operation
from battery
