digital input for Minimum
water level is high
1 = water level is ok when
digital input for Minimum
water level is low
The drive trips with F63 (Low
water level) when water level
is not ok. The fault is reset

P4.23 Maximum water level 0 6* 0 1966 Digital input for water level
P4.24 Maximum level logic 0 1 0 1967
Selections for maximum
water level logic:
0 = water level is ok when
digital input for Maximum
water level is high
1 = water level is ok when
digital input for Maximum
water level is low
The drive trips with F64 (Max
water level) when water level
is not ok. The fault is reset
with autoreset logic of
