Expert Power Control 1100/1101 Configuration
4.3.6 Configuration - Messages
4.3.6.1 Peak measurement period
Here you can set how long the peak values of the sensors and the current measurement should be recorded.
4.3.6.2 Generate Messages
This entries control the threshold values (Min- Max values) at which alerts are send via SNMP traps, Syslog and email.
4.3.6.3 Hysteresis
A Hysteresis value prevents that too much messages are generated, when a sensor value is jittering around a sensor limit.
The following example shows the behaviour for a temperature sensor and a hysteresis value of "1". An upper limit of "50" is
set.
Example:
49.9°C - is below the upper limit
50.0°C - a message is generated for reaching the upper limit
50.1°C - is above the upper limit
...
49.1°C - is below the upper limit, but in the hysteresis range
49.0°C - is below the upper limit, but in the hysteresis range
48.9°C - a message is generated for crossing the upper limit inclusive hysteresis range
49.0°C - is below the upper limit
