VOLTAGE SELECTION SENSOR SUPPLY
Sensor supply: 8.2V - 12V or 24 V DC:
A real power supply for the sensor is available.
The flowmeter can be powered with 8.2, 12 or
24V DC. Total power consumption: max.
50mA@24V. The voltage is selected with the
two switches at the left rear of the enclosure.
Refer to the figure 15 to select the required
sensor supply voltage.

Cable and wire selection
The unit complies with the Directives and Standards for Electro Magnetic Interference. For a reliable
signal transfer and prevention of external signal interference (crosstalk), for signal wiring, the
recommendation is made for a shielded (twisted pair) cable which meets at least the Category 5
cable standard.

TERMINAL CONNECTORS
The following terminal connectors are available:
Fig. 15: Overview of terminal connectors - Standard configuration and options
Terminal 1 - 2; Lock keypad:
This function allows you to connect a lock or jumper in order to completely disable the keypad while
the functions from the terminals remain available. Note that certain keys on the keypad can be
locked-out with SETUP 9.5 or password protected: read par. 4.2.11.
Read “Terminal 8-11” to lock the batch process.
Terminal 3 to 5, 29 to 32; Flowmeter inputs and supply
:
Three basic types of flowmeter signals can be connected to the unit: pulse, active pulse or coil. The
screen of the signal wire must be connected to the common ground terminal.
The input signal type has to be selected with the correct SETUP-function (read par. 4.2.8.).
