Dependency alarm 1,
Default:
The dependency of alarm 1 can be related to special functions, in detail these are the current
measurand, the min-value or the max-value.
causes the dependency either by pressing
the
[O]
-key on the front of the housing or by an external signal via the digital input. With
[P]
the
selection is confirmed and the device changes into menu level.
Example:
By using the maximum value
=
in combination with a threshold monitoring
, an alarm confirmation can be realised. Use the digital input for confirmation.
Threshold values / limit values,
Default:
The limit value defines the threshold, that activates/deactivates an alarm.
Hysteresis for threshold values,
Default:
The delayed reaction of the alarm is the difference to the threshold value, which is defined by
the hysteresis.
Function for threshold value undercut / exceedance,
Default:
A limit value undercut is selected with
(for LOW = lower limit value), a limit value
exceedance with
(for HIGH = higher limit value). If e.g. limit value 1 is on a threshold level
of 100 and allocated with function
, an alarm is activated by reaching the threshold level. If
the threshold value was allocated to
an alarm will be activated by undercutting the
threshold value, as long as the hysteresis is zero.
