An alarm can be signalized by a short flashing of the LED diode
on the device panel (Optical signalling - LED). In the case that only one
alarm originating from a measurement value is active, a yellow LED is
flashing. In the case that more alarms occur simultaneously,
or a system alarm or an alarm originating from an exceeded memory
occupancy limit occur, a red LED diode is flashing.
Besides, an alarm may be signalled acoustically by a characteristic
sound, which is repeated at regular intervals. If the device is connected
to an external power supply, the acoustic signal is more intense than
with battery power.
The operator alerted this way can confirm the acoustical or optical (LED
diode) signal and so mute it until a new alarm occurs (See the chapter
“
Controlling the datalogger from a keypad
”
).
Alarm events - Preferences _________________________
In the standard mode the alarm lasts only during the time when
the measurement values lie outside the allowed limits. As soon as they
return inside the allowed limits, the alarm will cease. In some cases,
it is desirable for the user to be informed of an alarm that has occurred
during his absence. If you enable the
Latched alarms choice
in the device setting, then every alarm occurring in the device remains
active until operator intervenes, irrespective of the measurement
values (i.e. until the time of manual cancel). Latched Alarms Memory
can be deleted either from SW Vision and/or by device restart by
buttons (the device Off and On). The availability of these choices
depends on device configuration settings.
Moreover, alarm evaluation may be enabled here for selected days of
the week only and for certain hours of the day. This setting can also be
used for system alarms, but it should not be combined with the above
described option
Latched alarms .
Alarm events
– Mute of signalling
___________________
In this panel you can enable or disable the alarm signalization
deactivation
– mute of signalling
. Depending on the device
configuration, deactivation of the signalling can be done either by SW
Vision and / or from the device keypad (in menu item ALARM on LCD).
The alarm signalling means either optical signalling - by a flashing
LED, or acoustic signalling - by an intermittent tone (beeping). The
alarm deactivation function allows you to deactivate (mute) the alarm
signalling for the duration of the alarm condition (the corresponding
alarm symbol remains on the display).
Deactivation of the signalling can be according to the device
configuration:
- permanent - the optical and/or acoustic signalling is deactivated
until new alarm occurs. In this case, the "Reactivate muted alarm
signalling" item must be switched off in the device configuration.
