where:
•
I
= is the DC current drawn by the pump range (0.00
to 9.99 Ampere)
•
P
= is the DC power drawn by the pump (range 0 to
999 Watt)
•
KRPM
= is the theoretical rotational speed of the
pump as a function of the controller output
frequency (range 3 to 56 KRPM)
•
°C
= is the temperature of the outer ring of the
upper bearing (range 00 to 99 °C)
•
X
= during operation a selected set point condition
(1 or 2 contrast inverted) appears when the
programmed threshold speed value is not reached.
