Enable thresholds
Options:
•
yes: The parameters and communication objects for threshold 1 for monitoring the Active power of
output A are enabled. The following parameters appear:
no
yes
Overwrite thresholds with download
or ETS reset
Options: no
yes
•
yes: The threshold values can be modified via the bus. With this setting, after a download or
ETS reset, the values changed on the bus are again overwritten with the parameterized values.
This setting applies for threshold value 1 and threshold value 2.
Delay for switching in s [0...65,535]
Options: 0...1...65,535
Then output can switch in dependence on the threshold values for active power. The switching re-
action occurs if the threshold exceeds or falls below the time parameterized here. This setting ap-
plies for threshold value 1 and threshold value 2.
Evaluation of threshold 1
Options: only if contact is closed
only if contact is open
always
•
only if contact is closed: Threshold 1 is only evaluated when the contact is closed.
•
only if contact is open: Threshold 1 is only evaluated when the contact is opened.
•
always: Threshold 1 is evaluated independently of the contact position.
Note
The evaluation of threshold 1 occurs based on the "calculated" relay position, i.e. if manual
switching has occurred or if a contact has welded, this will not be considered.
Threshold 1 lower limit
in W [0...4,600]
Options: 0...5...4,600
This is the lower hysteresis limit of threshold value 1. If the lower threshold is undershot, there is a
reaction.
