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 ) or acoustically
( Activate internal acoustic signalling)
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).
