The flow controller is also switched on thereby and is ready for opera-
tion.
If the flow controller does not switch on, continue by working through
the following points.

Check that the LiBus cable is inserted in the constant temperature
equipment. If the flow controller is not connected to the constant
temperature equipment by cable, the control valve in the flow con-
troller remains closed. Insert the LiBus cable in the LiBus interface on
the constant temperature equipment.

controller:
off - The flow controller does not regulate; it functions purely as a volu-
metric flow meter. The valve of the flow controller is fully opened. The
pump operates at the selected pump level. The currently measured
flow rate continues to be displayed by the constant temperature
equipment. This function is only performed when the pressure
limitation is switch off (see
Chapter 6.2 “Pressure limitation”
on page 22). If the pressure limitation is still active, the system will
regulate the pressure to the set pressure level.
on - The flow controller regulates to the flow rate set in the
Setpoint
menu.
