7.1 DIP switches

Switch number Description
1, 2 Selection of measuring input
3 Analog input (falling/rising)
4 Temperature sensor input (falling/rising)
5 Counter input (falling/rising)
6 Counter scale (x 1 or x 10)
7 Limits 1 and 2 of analog and temperature sensor inputs
8, 9, 10 GENIbus address
7.1.1 Selection of operational input
DIP switches 1 and 2 are used for choosing between
bus configuration, analog input, temperature sensor
input and counter input.
Bus configuration
If switches 1 and 2 are set to bus configuration,
IO 112 is operated from for instance Modular Con-
trols via GENIbus.
Analog input
If switches 1 and 2 are set to analog input (AI),
IO 112 is operated by means of the reset button and
rotary potentiometer of the module. See fig. 1.
The analog input is used for instance for the connec-
tion of a level sensor.

Temperature sensor input
If switches 1 and 2 are set to temperature sensor
input (PT), IO 112 is operated by means of the reset
button and rotary potentiometer of the module. See
fig. 1.
The temperature sensor is for instance used for
measurement of the liquid temperature or the motor
temperature.
Counter input
If switches 1 and 2 are set to counter input (CNT),
IO 112 is operated by means of the reset button and
rotary potentiometer of the module. See fig. 1.
By means of the counter function and a water meter
the pump can be set to pump for instance 2 m³ water
and then stop.
