OPERATION
Operating modes
You can select between five different operating modes:
MANUAL
Local operation and control of the pump without external control. The flow rate can be set by
specifying a stroke frequency. With a calibrated pump, the flow rate is set in l/h instead of
via the stroke frequency in %.
PULSE
The pump can be operated using incoming pulses with transmission, reduction or 1/1.
ANALOGUE
The stroke frequency of the pump is controlled via the received analogue signal.
MANUAL operating mode
Standard adjustment of the delivery rate is via the stroke frequency:
■
0-100% in 0.1% steps
►
Stepper motor pump
■
0-100% in 1% steps
►
Diaphragm pump (409.2)
After calibration, the flow rate is entered in the display as a setpoint in l/h or ml/h instead of by stroke frequency in %- (see “Cali-
bration of the delivery rate display” on page 20). In the Operating Messages view, the stroke frequency display is replaced
by the flow rate display. The total delivery volume is also still indicated in litres.
NOTE
In the ---PARAMETERS--- menu, there are no setting options for the MANUAL operating mode.
PULSE operating mode
ATTENTION
The maximum load capacity of the control inputs and outputs is:
Inputs: 30 V DC
Outputs: 30V / 30 mA
ATTENTION
The connection pin / (wire colour: yellow) is not protected against short circuit! In the event of a short circuit,
there is the danger of damage to the control electronics!
Therefore, it must be strictly ensured that the 24 V output connection is not directly connected to other connections.
ATTENTION
To avoid damaging the pump, perform parametrisation of the inputs and outputs before connecting the control cable.
