Operation state signaling
The power supply is equipped with LED, sound and remote indication systems. The LED indication is
used in order to bring attention of the personnel to the operation state of the device and to inform
about the reason of a potential malfunction. The sound indication system is activated together with
the lighting signalling.
Fault indication is maintained as active until it is deactivated using the vertical arrow button located in
the display panel. Short press of the button switches the sound indication system off, while keeping
the LED and remote indication systems active. The remaining indication systems can be deactivated
by pressing and holding the vertical arrow button for over 5 seconds. However, the use of the key is
effective only when the reason triggering the event generation is no longer present. The indication
systems are reset automatically only when the network power supply is restored and external signals
at the
EXT. FAULT 1
and
EXT. FAULT 2
inputs are no longer detected. In the case of the power failure,
instead of a continuous sound signal, a short, intermittent signal is generated every 15 seconds.
The LED indication system comprises four LED diodes located in the front panel of the power supply.
Three diodes represent the current operation mode (
MAINS
- green,
BATTERY
- yellow,
CHARGING
-
green), and the fourth - fault (
FAULT
- yellow).
The remote indication system includes three sockets denoted MAINS FAULT, BATTERY FAULT and
GENERAL FAULT. Each of the sockets has three plugs, switched between by using relays, completely
separated from all other circuits. During normal, correct operation of the power supply unit, relay
coils are active. It means that Mains Fault (power failure) indication, Battery Fault and General Fault
indications are executed by switching the appropriate relay off (current loss in the relay coil).
The contact setting in this state (so called zero-voltage state) has been presented next to each
corresponding
socket.
List of states of the LED and remote indication systems is presented in the tables below.
