The pressure of the circulating pump is adjustable in four grades. After
setting, the VFD-Info-Display indicates the corresponding value.
Adjustable pump capacity stage 1 ... 4
Illuminated display:
for pump pressure
Display for the adjusted pump pressure stage in the –OFF- mode.
Display for the effective pump pressure stage (rotation speed) after start.
For protecting the pump motor, the rotation speed changes with the load
applied, for example depending on the viscosity of the bath fluid at different
working temperatures.
