The pump can also be operated in a calibrated state in all operating
modes if it is to meter extremely precisely. This can be useful with high-
viscosity feed chemicals but less so with feed chemicals with a similar con‐
sistency to water.
This facilitates the switch-over to a fixed adjustable capacity in the
via the "External control" terminal.
This permits a simple timer program to be set up without the need for an
additional timer module.
The following functions are available as standard:
Information about the liquid level in the dosing tank is reported to the
pump. A two-stage level switch has to be fitted for this purpose, which is
connected to the "Level switch" terminal. A suction lance with continuous
level measurement can also be connected to the pumps.
The pump can be remotely stopped via the "External control" terminal.
The pump can be stopped without disconnecting it from the mains/power
supply by pressing
Priming can be triggered by pressing
The pump has several connecting options available:
The relay can close a connected power circuit (e.g. for an alarm horn) in
the event of warnings or fault messages (e.g.
The relay can be retrofitted through the slot in the front of the pump – refer
to the installation instructions for "Retrofitting relays".
This combined relay can generate a contact for an adjustable volume via
its pacing relay in addition to functioning as a fault indicating relay.
The relay can be retrofitted through the slot in the front of the pump.
The current output signal I indicates the pump's actual calculated metering
volume. The relay can be retrofitted through the slot in the front of the
pump.
The option also always includes a fault indicating relay or a pacing relay.
