15.12.8 Changing the error limits, the warning limits and the hysteresis
of the differentiation factor
A monitored value can be:
• in the normal operating range.
• in the warning range,
• in the error range.
You can set 4 limit values: 2 error limits and 2 warning limits.
→
To set the limit values, see chapter 15.12.8 Changing the error limits, the warning limits and the hys -
teresis of the differentiation factor .
Fig. 52 in 15.4.5 explains how the device reacts when the monitored value enters in another range (for
example, from the normal range into the warning range). The reaction time depends on the hysteresis value
and if the monitored value increases or decreases.
By default, the monitoring of the DF and the diagnostics are all disabled.
To change the error limits, the warning limits and the hysteresis of the DF, do the following:
→
Go to the
CONFIGURATION
