14-62 Inv. Overload Derate Current
Range: Function:
95 %* [50 -
100 %]
Enter the current level (in % of rated output
current for the frequency converter) when
running with reduced pump speed after load
on the frequency converter has exceeded
the allowable limit (110% for 60 s).

NOTICE
This parameter is only changing function by
performing a power cycle.
[0] No Select [0] No to use the frequency converter's 24 V DC
supply.
[1] * Yes Select [1] Yes if a 24 V DC external supply is used to
power the option. Inputs/outputs are galvanically
14-80 Option Supplied by External 24VDC
Option: Function:
isolated from the frequency converter when operated
from an external supply.

D = Default setting. X = Possible selection.
1) Only these faults are congurable on the FC 202. Due to a software limitation with array parameters, all others are shown in the MCT 10 Set-
up Software. For the other parameter indices, writing any other value than its current value (that is, the default value) returns a value-out-of-
range error. Thus, it is not allowed to change the fault level for the non-congurable ones.
2) This parameter has been 1490.6 in all rmware versions up to 1.86.
3) Alarm 244, Heat sink temp., alarm 245, Heat sink sensor, and alarm 247, Power card temp. are used for multiple power cards.
