6. Mounting
Mechanical mounting
All versions of the transmitter can be mounted either directly or by means of 3
mounting clips to the item being measured. Both methods of mounting and the
relevant drilling and cut-out plans can be seen from Table:

Mounting/positioning
Three
M3
screws are needed for the
“directly”
mounted versions and three
M4
screws for those
“with clamps”
. The screws are not supplied, because the required
length varies according to the thickness of the mounting surface.
When deciding where to install the transmitter (measuring
location), take care that the
“Ambient conditions”
given in
Section “5. Technical data” are
not exceeded
.
Angular position transmitters of the KINAX 2W2 range do not require a mechani-
cal zero position mark (however, this is made if required by the customer). After
mounting, the transmitter can be moved to any position and confi gured using the
2W2 software. A power supply connection to the KINAX 2W2 is not required in
order to use the 2W2 confi guration software (Fig. 7; AUX switch on the PK 610 in
the ON position.
The angular position transmitter must only be programmed
outside of the Ex areal!

If you programm the KINAX 2W2 with a connected power
supply, then the switch on the interface PK610 must be im-
perative switched to OFF. If this is ignored, this can lead to the
destruction of the device.
Positioning procedure for the KINAX 2W2
1. Mount the angular position transmitter and mechanically connect it to the object
to be measured. Connect the KINAX 2W2 to the programming device according
to Fig. 7. Start the 2W2 confi guration software. If necessary, confi gure the device
with the required measuring range data.
2. Place the measuring device in a defi ned position (prefereably the zero position).
3. Select the
“Adjustment”
menu item under
“SERVICE”
in the confi guration
software. In the
“Mechanical position”
window enter the current angle of
the measuring device and then select
“Adjust”.
The measuring device is now
confi gured for the defi ned angle.
7. Electrical connections
For connecting the external wires, the transmitter has 2 soldering pins at the back
(Fig. 8) or a connecting print with screw terminals (Fig. 9). The soldering posts
suffi ce Protection Class IP 00 acc. to IEC 60 529.

Note that, …
… the data required to carry out the prescribed measurement must
correspond to those marked on the nameplate of the KINAX 2W2
(Range, Output, Supply Voltage)!
… the total loop resistance connected to the output (receiver plus
leads)
does not
exceed the maximum permissible value R
ext.
! See
“Measuring output”
in Section “5. Technical data” for the maximum
values of R
ext.
!
… twisted cores must be use for the measured variable input and
output leads and routed as far away as possible from power cables!
In all other respects, observe all local regulations when selecting the
type of electrical cable and installing them!
In the case of
“Intrinsically safe”
explosion-proof versions
[Ex ia] IIC, the supplementary information given on the EC-Type-
Examination Certifi cate, the EN 60 079-14 and also local regulations
applicable to electrical installations in explosion hazard areas must
be taken into account!

8. Setting the beginning and end

T
he analog output can be fi nely adjusted using the 2W2 confi guration software.
Select the menu item
“Adjustment”
under
“SERVICE”
. In the
“Analog output”
window, the zero position and the end value can now be adjusted.
Procedure:
1. Put the transmitter into operation and connect the programming device according
to Fig. 7 (AUX switch on the PK 610 in the OFF position).
2. Place the measuring device in the zero position, i.e. in the position in which the
KINAX 2W2 should output 4 mA. Adjust with the
“ZERO”
virtual knob until the
output is correct.
