Tab. 7-16: Parameter list of two points / double pump control
Choose different control mode and logic according to the type of pump by
F4.28.
For two points pump F4.30 (Vg1) reference the maximal displacement, and
F4.31 (Vg2) represents the smaller displacement. For double pump F4.30 (Vg1)
reference the main pump, and F4.31 (Vg2) is equal to the displacement of addi-
tional pump.
According to the pressure feedback, actual speed, F4.32, F4.33 and F4.34, the
pump switching logic will be calculated and carried out via the relay output,
once the output has been set, see F2.40, F2.41.
