4.2.4 Monitoring
The value to be monitored can be adjusted.
The load voltage was used in this example.
Value range
Your setting:
Current measured
value
0 to 9999.9
The absolute minimum limit value for load voltage, load cur-
rent, power, resistance, supply voltage, or device temperature
can be monitored.
The measured values in the master branch are measured.
Example:
If the voltage falls below 20 V, an alarm is issued.
Current measured
value
0 to 9999.9
The absolute maximum limit value of load voltage, load cur-
rent, power, resistance, supply voltage, or device temperature
can be monitored.
The measured values in the master branch are measured
Example:
If the voltage exceeds 100 V, an alarm is issued.
0 to 1 to 9999.9
The switching differential at the minimum or maximum limit
value
Current deviation
from teach-in
(i.e. if it exceeds 0 %)
the load has become
high-impedance;
if it is below 0 %,
the load has become
low-impedance
0 to 10 to 100 %
Partial load failure or partial load short circuit:
The monitoring value for the percentage modification of the
load is set (undercurrent or overcurrent).
By displaying the current deviations in all three phases of the-
Teach-In value, it is possible to check how, for example, the
resistance change behaves over the entire operating range.
The load monitoring limit value can then be adjusted accord-
ingly.
