Alarm output
In undisturbed ope-ra-
tion, the alarm relay at-
tracts, and the contact
of the alarm output is
closed. In case of a dis-
turbance, the alarm relay releases and the contact is
opened. Various events can be assigned to the alarm
output via or-conjunctions. One alarm number, one
alarm delay and one alarm duration are assigned to
each event. The alarm call can be activated or
deactivated for each event.
"on"/number = Alarm call is activated.
"oFF" = Alarm call is deactivated.
The following events can be assigned to the alarm out-
put:
Alarm call
If one or more alarms occur, Prophi changes to an alarm
indication. In the alarm indication, the errors are shown
by their number. In the following example, the errors
"lower voltage" and "compensation power" occurred.
The time and dimension of the error is not saved.
Give a receipt for alarms
If you confirm the alarm message with key 3, you reach
the last measured value indication. The error symbol
"Error" remains within the measured value indications
until the errors are not valid anymore.
1 5 Error
Low voltage Compensation power
If other error messages appear after the confirmation of
an error message, the alarm indication appears again
with new error messages. Older errors, which are not
valid anymore, are flashing.
Example: Programming compensation power
Leaf to the first alarm in the expanded programming
with key 3. Please leaf to compensation power (5) with
key 2 and confirm with key 1.
Pressing key 1 you leave the programming mode and
with key 3 you can continue leafing through the ex-
panded programming.
With key 3 the alarm "compensation power" is acti-
vated (on), with key 2 the alarm "compensation power"
is deactivated (oFF).
