%I prewarning and limitation

5.3.5.1

%I prewarning

%I limitation

5.3.5.2
The "%I prewarning" parameter can be used to specify
• from which scale value on the message "Phase angle prewarning re­
ached" is to be displayed.
The timer is thus able, in the KSR mode, to call your attention to an im­
minent %I limitation resulting e.g. from cable losses in the secondary
circuit.
Parameter setting in BOS:
In "Programming", flag "Electrode", parameter group "Limitation"
The parameter value must be lower than the value for the %I limita­
tion.
" Parametrize the %I prewarning first.
The parameter value must be higher than the value for the %I
prewarning.
Using the "%I limitation" parameter, you define the maximum permitted
scale value. It limits
• the scale value specified by the controller to the power supply unit in
KSR mode, and
• the possible programming input in PHA mode.
If the %I limitation is activated, the timer will output the message "Maxi­
mum phase angle".
Parameter setting in BOS:
In "Programming", flag "Electrode", parameter group "Limitation".
The input value for %I limitation is effective absolutely!
The function "%I correction" (refer to page 292) and "%I stepping"
(refer to page 285) can therefore lead to the activation of the %I limit­
ation.
