General system description
An as compact as possible and universally usable fault annunciator is needed especially for use in high voltage switching
areas. The battery- supported supply voltage usually is 110 or 220 V DC and is directly connectable.
The fault indication is done by 16 red LED‘s built in the front panel (other colours on request) with 1-frequency flashlight
(as option 2-frequency). The LED‘s can be marked via slide-in labels with 40 mm textlength and 3,5 mm height for each
channel.
The fault annunciator has 2 collective reports, which are assigned strictly to the signal inputs. (Input 1 ... 8 ∑1;
input 9 ... 16 ∑2). The contacts can be factory set as NO or NC contact. Furthermore there are 16 potentially isolated
relay outputs provided, which can be triggered either parallel to the signal inputs, or to the lamp outputs that whether a
parallel lamp tableau can be triggered, or alarms can be transmitted to the central control system. The ackowledgement
of horn and lamp can be done by internal or external push buttons. A push button for lamp-test is integrated in the fault
annunciator.
The 16 signal inputs are subdivided into 4 circuits, therefore alarms out of different phases or (optional) voltages can be
processed.
Function programming
After removing the front panel the following functions of the annunciator can be selected by DIP-switches at the bottom
side on the left side of the PCB-board.
key Meaning
Input processing
OFF Normally open working of the inputs
1
ON
An alarm is detected by applying voltage at the input.
Normally closed working
A voltage is supplied to the inputs in a non-alarm condition. A missing voltage is detected as a
fault.
Horn triggering
OFF Horn retriggerable
2
ON
A following alarm activates the horn again, if it is not active already.
Horn not retriggerable
A following alarm does not trigger the horn. Only after the elemination of all alarms the horn can be
retriggered.
Alarmsequence
OFF New-value processing
3
All incoming alarms are indicated as flashight. Already gone, but not acknowledged alarms are
indicated by flashlight in opposition.
ON First-value processing
The first incoming alarm is indicated by flashlight all others in steadylight.
Collective report and horn
OFF Collective report and horn as standard
4
The signal relays are pulled-off in normal condition and pull-in by incoming alarm.
ON Collective report and horn inverted
The signal relays are pulled-in by normal condition and pull-off by alarm or loss of voltage
