UNICONTROL Electronic S-SW-8 User Manual

5 /10
Warning:
!
The earthed mounting structure "C" must be connected to the reference poten
tial of the evaluation
unit (X1/3) via its own line!
The potential of the mounting structure (PE) serves as a reference potential for the evaluation
unit.
!
The number of spacers should be
calculated and distributed over the length of the electrodes to
guaranty reasonable mechanical stability.
!
The measurement and opposite electrodes must be fixed on the mounting structure avoiding
electrical contact. Ignoring this rule, will change the wa
y the electrodes work and make them
unusable for the application.
2.3 Configurations and Indication elements
2.3.1 SW1: Set sensitivity (relay switching point) & start calibration (SW2-2 OFF)
With the rotational selector SW1 the sensitivity (switching point of the relay) is set and a new adjust-
ment of the bias point of the S-SW-8 can be triggered.
●
SW1 cw rotation
→ Increase sensitivity
● SW1 a-cw rotation →
Decrease sensitivity
●
SW1 > 5s pushing
→
New calibration of the sensor is done. The LED4 blinks until the calibration
process is completed (up to 60s). The settings of sensitivity, hysteresis
and memory function are preserved.
2.3.2 SW2: Setting of functional properties
The 2-poles switch SW2, leads to the following behavior of the evaluation unit:

●
Hysteresis
(5 or 10%)
:
It is the difference in the sensor signal between the switch-
on point
(occupied) and the switch-off point (free) for the relay.
The sensor signal level for the switch-
ON point is stronger than the
switch-
OFF point. A larger hysteresis means that the switch ON/OFF
points are distanced.
●
Memory Function OFF
SW2-2 = OFF
:
Each time the power supply of the evaluation unit is switched ON,
a new adjustment is started automatically.
The last set sensitivity counter is retained, but all other operating pa-
rameters are reset to the current operating situation. The readjustment
means that any objects that are located in the detection area are "for-
gotten". This means that t
he relay is dropped out, even if it was ON in
the last power down. Only additional objects would switch the relay on
again!
●
Memory Function ON
SW2-2 = ON
:
When the power supply of the evaluation unit is switched ON, no
new adjustment is made. The last valid operating p
arameters are
restored from non
volatile memory and used. Changes in the reference
conditions in the meantime are taken into account by moving the ref-
erence point.
This function is useful and recommended if there is a work-
piece
in the detection area at the time of switch-OFF and should be rec-
ognized when it is switched ON again.
However, it must be the
same object in the same position
, otherwise the difference is treated
as a change in the reference conditions. This would result in an
invalid
displacement of the reference point and thus a malfunction.
!
Case
a detected object is removed from the detection area while
the sensor is turned-OFF, in the next turning-
ON, the sensor will
incorrectly behave as if the object is still there and the relay will
