The value displayed for parameter 1-3-1-3 Setpoint is 6.7 bar.
Parameter 1-3-1-1 for the actual feedback value in the corresponding unit displays
the current actual value.
7.1.1.4.3 Closed-loop control mode using field bus
If the setpoint is specified using a field bus (e.g. LON, Profibus), the Setpoint Source 3
parameter
(3-5-4-3)
has already been set to Remote Setpoint for this purpose.
However, the bus module needs to be enabled after installation by using the Field
Bus parameter
(3-2-1-5)
so that the setpoint can be read. The setpoint specifications
have to be taken from the relevant product literature of the bus modules, but are
matched with the basic settings of PumpDrive.
7.1.2
Dual pump configuration
The motor parameters must be set prior to commissioning. (
Dual pump module accessory kit
The DPM set of accessories is available for controlling redundant variable speed twin
pumps (e.g. Etaline Z PumpDrive) or two identical variable speed pumps operating in
parallel. The dual pump module (DPM) is available as a separate accessory/spare part.
The dual pump module can only be used in combination with the standard control
panel for the PumpDrive Basic model. It cannot be used in combination with the
blanking plate or the graphical control panel.
NOTE
Dual pump modules are available for redundant variable speed twin pumps or two
identical variable speed pumps operating in parallel.
Refer to the operating manual for the dual pump module.
