▪ How to program the alarm thresholds
The F190-A can give an alarm message on the display. When set to on, at the same time, the
digital outputs can give a signal for processing by an external device. Note that it is also possible
to set or change the alarm thresholds from the setup menu.
This procedure is applicable to all the alarm thresholds. Only the procedure for ALARM LL is
given. From any operator page, press the SELECT/▲ key, to find the required submenu.
Action
1 From any operator page,
press the SELECT/ key, to
find the submenu: ALARM LL.
2 Press the PROG/ENTER key
to access the submenu:
ALARM LL.
3
Use the SELECT/ key to
increase the digit. Use the
CLEAR/ key to go to the
next number.
4 Press the PROG/ENTER key
to confirm the selection.
▪ Process alarm
When the process signal is outside the allowed range, an alarm message will be displayed at the
bottom line of the display indicating the type of alarm: LO-LO ALARM, LO ALARM,
HI ALARM or HI-HI ALARM.
The alarm is terminated automatically as soon as the signal is in its range again. Due to the setup
configuration it might be that the process is outside its range without an immediate alarm.
▪ Clear Alarm outputs
The Operator has the possibility to clear the alarm outputs, e.g. to turn off an alarm bell. This
feature can be enabled individually for each output in SETUP-menu 8. When the clear action is
performed, all enabled outputs that are connected to an active alarm status will be cleared.
To do so, press the CLEAR/ key at operator level when the actual measurement value is
shown. The text "CLEAR OUTPUTS" is shown and pressing the CLEAR/ key again will clear
the outputs. To avoid a reset at this stage, press any other key or wait for 20 seconds.
Be aware that only the output(s) is cleared; the alarm itself remains available and visible
on the display. When the same or an additional alarm (re-)occurs, the output(s) is
triggered again!
▪ Low-battery alarm
When the battery voltage drops, the "low-battery" icon will be displayed continuously. The battery
MUST be replaced shortly after!
The remaining lifetime after the first moment of indication is generally several days up to some
weeks. See paragraph 6.3 for further information on battery replacement.
▪ Alarm
When the alarm indicator is shown, refer to Appendix B: Problem Solving.

Remark
-
If you wait too long, the
program mode goes off and
changes are not saved.
The 0 (zero) in front of the
number will not show when
the setting is saved.
The alarm is only shown on
the display. For an alarm on
an external device, set the
function of the digital output.
If you do not press the
PROG/ENTER key to
confirm, your selection is not
saved.
