lower than ). Enter this limit value. In binary inputs, only the input state
must be defined. Subsequently, the alarm delay time must be entered
(
for the duration of) . This delay time serves to eliminate contingent
momentary overshoots of the limit value. The hysteresis, too, has
a similar significance (
Alarm hysteresis ). It prevents the alarm
from oscillating in the case that the measurement value varies around
the alarm limit value. It is not recommended to set it equal zero.
Thus, the setting for generating an alarm is completed. It remains
to decide, whether the alarm should be indicated optically by means
of a LED diode on the device (
Optical signalling - LED ), acoustically
( Activate internal acoustic signalling) or by sending a alarm text
message to up to four selected recipients (when alarm
occurs/disappears, send S
MS to selected recipients ).
In SMS messages you can determine whether they are supposed to be
sent out on alarm generation and on alarm disappearance, too. In both
cases add a custom text description of the status that the recipient
will see in the message.
Alarm events ____________________________________
The device makes it possible to evaluate alarm situations, which can
either originate from the measurement data, or they can notify of
a certain device condition (exceeding the memory occupancy limit,
system alarms). The individual alarm situations can be assigned
the way of their signalling to the user.
An alarm originating from a measurement value is every time signalled
on the device display by means of a bell icon ahead of
the corresponding measurement value. General information about any
alarm occurring in the device is displayed by
ALARM warning on
the device display (except for an exceeded memory occupancy limit,
which is signalled by a flashing
Memory sign).
