Example:
min. 10mA / max. 18mA / Hysteresis 2
When a limit is violated the alarm status is reset when 16mA (18-
2) or 12mA (10+2) is reached.
This function prevents the limit value from ‚flickering‘.
Delay Time: Triggering of the alarm is delayed by this time (in
minutes) to compensate for momentary limit violations.
Interval: Enter here the send interval (in minutes) at which a
message should be sent when there is an active alarm. If you want
to send only a single message, enter here „E“.
Timer: Here you configure when the alarm monitor should be
turned on and off. The interval set here is based on the CRON
service as used in Linux/Unix systems. Valid characters are:
Trigger: Define here the triggers for the alarm e-mail. Multiple
selections are possible.
Min./Max.: Specifies the lower and upper limit. The range within
these limits is considered to be „valid“.
Hysteresis: You can also specify a hysteresis value used to reset
the alarm status.
