3.2 Electrical connections
● Sensor Electrodes: – Coaxial Cable Shield: from the evaluation unit X3/2 to the opposite elec-
trode "B".
–
Coaxial Cable Core: from the evaluation unit X3/1 to the measurement
electrode "A".
● Evaluation unit: – Connect X1/1 and X1/2 to the power supply (24V AC / DC).
The polarity ± doesn’t matter.
–
Connect X1/3 to the earth of mounting structure "C" using a separate
cable.
No additional connection to the earth potential is admitted from
here! X1/3 is not used for safety grounding, but exclusively for ref-
erence potential at the sensor electrodes.
– Connect X2 (relay contacts) to the higher-
level control system according
to their function.
–
Connect X3/1 to the sensor electrode "A" through the internal conductor
of the coaxial cable.
– Connect X3/2 to the opposite electrode "B" through the shield of the co-
axial cable.
4 Installation
1.: Produce and install the sensor electrodes as described in chapter "2.2 Sensor Electrodes".
2.:
Place Electrodes and evaluation unit as close as possible. Connection cables may not exceed
100cm.
3.:
Check and make sure that there is NO:
– short circuit between the electrodes,
– electrical connection between measuring or opposite electrodes and mounting structure.
– electrical connection to the machine ground.
4.: Connect the coaxial cable to the sensor electrodes. The core goes to the measurement elec-
trode and the shield to the opposite one.
5.: Connect the reference potential of the evaluation unit X1/3 direct to the earthed mounting struc-
ture.
6.: Connect the supply voltage (24VAC / DC) to the evaluation unit (X1/1, X1/2).
7.: First operation
By the first operation an adjustment must be made. The state of the detect area will be evaluated
and saved as a reference.
!
The detection area must be free to process adjustment! No working piec
es, stored objects or
people may stay around, since they influence the adjustment signal.

Switch on the evaluation unit
. The green LED6 must light up.

Carry out adjustment
The adjustment behavior of the evaluation unit depends on the switch SW2-2 settings:
SW2-2 OFF After first switching ON, the evaluation unit starts an automatic adjustment.
SW2-2 ON
The
adjustment is not
automatically
carried out. Adjustment must be forced
by pressing the SW1 button for at least 5s.
The elapsed time can be
seen on the behavior of LED2: After 2s, LED2 lights
UP and after 5s it goes OFF again. The adjustment process starts shortly. The
button SW1 can now be released.
With SW2-
2 = ON, the operating parameters from the last application still
apply. This can lea
d the unit changing to the error state. The red LED4
then indicates this state by permanently lighting.
– The red LED4 blinks during the adjustment process.
–
The adjustment process has been successfully completed when LED1 blinks (1 / s).
– If no
working point is found during the adjustment, the evaluation unit changes to the error
state. This is indicated by the constant lighting of the red LED4.
8.: Place the working object in the sensing area.
