Alarms can be signaled using the LED diodes directly on the
Multilogger (
Optical signalization - LED ). Since the Multilogger can
work in the battery mode, additional options are available for
minimizing the current consumption. For a state without an alarm can
be selected green LED indication. When the device is powered from
batteries, you can select more energy economical mode, under which
the LED diodes only shortly blink in the case of an alarm.
In addition, the alarm can be signaled acoustically with characteristic
sound that is repeated at regular interval. Service personnel can
easily confirm the audio signal and thus make it silent until a new
alarm occurs. These settings can be performed in the section
Mute of
signalization .
Alarm signaling can be also performed using the ALARM OUT output.
Upon an alarm, the Multilogger can switch on the open collector
transistor of this output in accordance with the description in Chapter
“ ALARM OUTPUT”.
This transistor can be optionally switched on or
switched off when there is an alarm. The Mute function can be also
used for this output.
Alarm events - Preferences ________________________
In the standard mode, the alarm exists if the measured value is out of
limits, and the alarm becomes inactive if the measured value returns
to its limits. In some cases it is suitable that the user, who comes to
the device after a longer period of time, can easily make sure that no
alarm has occurred while he/she was gone. If you activate the
Latched alarms option , all alarms that occur in the Multilogger will
remain active until the service personnel is not confirmed them.
Here you can also allow remote erasing of the alarm memory and
remote
deactivation of alarm signalization from the
software Vision or from the web ( Remote Mute & Erase of
Latched alarms); moreover, you can permit or forbid alarm
deactivation from the device keyboard ( Local Mute enabled) . To
protect access to these functions, you can use the PIN2 code
(Security panel).
Furthermore, you can allow alarm evaluation here only on
certain days of the week and within defined range of hours per day.
It is not suitable to combine this setup with the above described
Latched alarms option .
