Water meter
The controller has two independently operating water meter inputs.
Water meter 1 can, e.g., be used to record the raw water quantity. Water meter 2 can be
used to record the permeate quantity.
Set the impulse numbers for the contact water meters or turbines in the menu:
Request the recorded quantities in the SERVICE menu, e.g.:
"M"
 SERVICE  WATER METER 1  Quantity: 9143 l
"M"
 SERVICE  WATER METER 2  Quantity: 4360 l
The memories of the water meters are also deleted in the SERVICE menu.
Metering
Use the output "Impulse" for the control of a dosing pump if metering is to take place
during operation. Program the water meter to be used for metering, the volume for which
an impulse is given as well as the impulse length.
Please note that it is not possible to
enter an impulse interval in litres which is smaller than the basic number of the
water meter.
Alternatively, it is also possible to use the impulse output to duplicate the contact of the
water meter signal. We recommend this if you, e.g., wish to control a hardness
measuring instrument (e.g. Testomat 2000) quantity-dependently. For this, please
observe the instructions of the connected hardness measurement instrument.
Funct. IN 0/4-20mA input
Program the measuring range of the sensor if the osmosis plant is equipped with a
pressure measuring transducer for the measurement of the pump pressure:
Request the current pressure in the SERVICE menu, e.g.:
"M"
 SERVICE  Pressure 14.3bar
Function OUT PR output
Program the function of this volt-free relay output PR :
CDmax: Relay switches if the conductivity

or
Tank empty: Relay switches if the storage tank is empty
or
Production: Relay switches if the plant is in operation
or
Stop/Standby: Relay switches if the plant is in standby or has been stopped.
Interface
Program the type of the built-in serial interface according to the used plug-in card. The
RS232 is a standard interface for firmware updates via PC or for connecting a protocol
printer.
The interface card RS232/RTC/0-20mA is equipped with a current transformer which can
be used for the output of the conductivity. Program the desired/necessary output signal.
Baud rate
Select the speed rate of the serial interface.
