INSTALLING THE SCALE SENSORS
The sensors delivered by Antti-Teollisuus incorporate complete kit for installation in the
dryer base leg. At least 2 sensors are required in order to achieve a measuring accuracy
of ±100 kg. If scale sensors are installed under each leg (4 pcs. in all), in theory a meas-
uring accuracy of 1 kg can be achieved. This requires that pipes to and from the dryer be
equipped with exible parts. The dryer in which the sensors are installed must be located
indoors and must not come in contact with any other structures of the dryer.
Note! If 2 sensors are installed, they must be located under legs on the same side of the
dryer (see Illustration).

Antti-Teollisuus delivers scale sensors with capacity of 20 000 kg. Thus total weight of
dryer may be 80 000 kg. Slight exceeding may only cause minor inaccuracy in measuring
results.
To install the scale sensors, the dryer legs must be shortened by 121,5 mm (see illustra-
tion on the next page).

The upper plate (top plate) of the scale is attached to the leg by welding or to a concrete
slab by bolts using wedge anchors. Note! The essential sensor part must not be in place between
the top and bottom plates while the plates are being attached by welding to the leg or bond plate.
We recommend placing the cable coming from the scale in a protective pipe. Connect the
free end of the cable to the connection strip behind the PAXS panel meter. Please refer to
point "meter´s basic connections" for instructions.
We recommend installing the scale terminal i.e. panel meter in the cover of the centre.
Please refer to point "installation of the meter in the panel" for instructions.
As required, shorten or extend the sensor cables to suitable length. The extension ca-
ble must absolutely be of anti-interference type, such as, e.g., well-regarded JAMAK-C
2x(2+1)x0,5. Connect the sensors parallel to each other. The cables of the two sensors go
in under the connection strip on the panel meter. When 4 sensors are being installed, we
recommend using a connection box. Join the cables coming from the sensors inside the
connection box. Then the connection box and the panel meter will be connected by only
one cable.
Solder all connections to avoid wrong reading due to poor contact.
General information of scale terminal, i.e. PAXS panel meter:
The paxs panel meter is intended for use with strain-gauge transducers, specically de-
signed for weighing purposes. The meter has free card slots for following optional output
cards:
If you want to have additional functions:
- Analog output card (4 – 20 mA ) for displaying the readouts also on the logic display
(requires that Antti-Logicontrol is used for control centre of the dryer). Setting the
parameters is instructed later in this manual.
- If you want to print out the weighing results displayed on the panel meter, you need
a RS232 serial communication card. Setting the parameters is instructed later in this
manual.
First read carefully through the following commissioning instructions and then
carry out the commissioning and programming procedure stage by stage.

STAGE 2 OPENING THE BOX AND INSTALLING THE CARDS, JUMPERS AND
QUALITY ASSURANCE UNIT
WARNING! RISK OF FATAL ELETRIC SHOCK. BEFORE TURNING ON THE POWER, MAKE
SURE THAT THE METER BODY IS INSTALLED IN A CORRECT POSITION IN THE BOX
If the meter is used for basic measuring operations there is no need open the meter.
But if you wish to insert any of the available optional cards, install the quality assurance
unit for showing the readouts on the display or change position of the jumpers, the meter
must be opened. The meter´s main circuit board, showing the position of each card and
jumper connection, are shown in the illustration on the next page.
The meter body is removed from the box by depressing rmly the nger grooves at the
rear of the box and, at the same time, pulling out. Once the nger grooves are depressed,
the catch screws are released from their slots in the box. At rst, release one catch and
after that the other catch on the opposite side. Once both of the catches are released, the
body can be pulled out of the box. After that it is possible to dismantle the installation kit
holder.
Once the meter is open, the free card slots (max. 3 kpl) are visible in the main circuit
board. Before inserting the card, check out the correct slot in the picture on the next page.
After installation, put the meter back in the box and ensure that the box is properly closed.

Usually there is no need to change the jumper settings. We recommend, however, that you
check the jumper settings before resuming the operation.
After installation of any optional cards, put the meter back in the box and ensure that the
box is properly closed.

STAGE 3 INSTALLING THE METER IN THE PANEL
Make an opening (92 mm x 45mm) in the panel in accordance with the illustration below.
Leave an area of (54mm x140 mm) next to the rim of the opening free from any installa-
tions as shown in the illustration. Insert the meter in the opening with its rear part rst and
x it using the installation kit. Attach the sealing around the rim of the opening between the
meter and the panel. After installation the panel´s protection class on the frontside is IP 65.
The inside of the panel must be free of any moisture or dust.
STAGE 4 BASIC CONNECTIONS OF THE METER
The 230-V power supply for the panel meter may be taken from behind the control centre
of the dryer from the pilot fuse.
For basic use, only connect the terminals 1-6 at the rear of the scale display. Terminals 7-
10 are client inputs that need not be connected. Terminals 12-15 are put to use if an op-
tional serial communication card (RS 232) for the printer is installed. Terminals 16-19 are
put to use if an analogue card is installed inside the display. The analogue card makes it
possible to transmit the scale readout to the panel display on the logic centre or to the PC
control. The terminals 20-25 are not in use.
