2. I NTRODUCTION
2.1 Overview
BX11 family instruments are economic and powerful state-of-the-art technolo y indicators for wei hin and
force measurements. These instruments convert the low level strain a e load cell analo si nal to di ital
si nal in hi h resolution and accuracy to transmit di ital data to PLC or PC. With a wide variety of interface,
BX11 instruments are used for any type of wei hin processes and force measurement includin tank and
silo wei hin , dynamic wei hin , check wei hin , fillin , tension /compression force measurement etc.

4. I NSTALLATION
PRECAUTION: Please read this section carefully before installation of the instrument. Applying the
recommendations in this section will increase your system reliability and long term performance.
4.1 Recommendations
4.1.1 Control Cabinet Design
Warning: Please care the following warnings for designing the control cabinet which will increase your
system reliability.
The control cabinet should be desi ned so that Analo Di itizer can operate safely. The panel should be
placed clean area, not ettin direct sun li ht if possible, with a temperature between -10 ºC and +40 ºC,
humidity not exceedin 85% non-condensin . All external cables should be installed safely to avoid
mechanical dama es.
BX11 instruments are very low level si nal measurin instruments. To avoid electrical noise, BX11 should be
separated from the equipments that produce electrical noise. Preferable use metal cabinet a ainst radio
frequency interference and the cabinet shall be connected to round a ainst the electroma netic
disturbances. Load cell cable trays must be separated from others, if possible. If there are noise- eneratin
equipments such as heavy load switches, motor control equipments, inductive loads etc., please be careful
a ainst the EMC interference in the cabinet. If possible protect BX11 instruments with the faraday ca e or
install them in separate section or install them far a way from this kind of equipments. Connect parallel
reverse diodes to the DC inductive loads like relays, solenoids etc. to minimize volta e peaks on the DC
power lines.
4.1.2 Cabling
All cables comin to the control cabinet shall be shielded. Please use separate cable tray for these low
si nal level cables. Distance from load cell cables, interface cables and DC power supply cables to power
line cables shall be minimum 50 cm.
4.2 Mechanical Installation
Take care to the housin dimensions and the su ested panel hole dimensions iven in the Page 10. To
avoid electrical noises, protect your indicator which has very low input si nal level from the equipment that
produces electrical noise in panel mountin .
4.3 Electrical Connections
Warning: Please always remember that BX11 instruments are very low voltage measuring instruments. Your
control cabinet design and proper installation increases reliability and performance of the instrument. Please
do not forget that the instrument must be powered off before inserting or removing any peripheral
connector.
The electrical installation and quality of instrument’s roundin will provide wei hin accuracy and the
safety of your indicator. If the ener y condition of your plant is bad, prepare a special power line and
roundin . All required electrical connections should be done as described below.
If you have to service the indicator, turn the power off and wait at least 30 seconds before interferin .

BX11 Smart Process Indicator, Technical Manual, Rev. 1.2, May 2013
Pa e 14 of 92
There is a DIP switch on BX11’s rear side and its position should be “ON” ( downward ) to chan e the
metrolo ical related parameters includin calibration. There is no need to open the housin to chan e the
position of this DIP switch. If there is not set-up DIP switch on the instrument for industrial usa e, its
position is always ON.
Figure 4.1 - The location of calibration DIP switch
4.3.1 Power Supply Connection and Grounding
Power supply volta e of the instrument shall be between 12 VDC and 28 VDC. The pin confi uration of the
24 VDC power supply connector located ri ht - bottom of the instrument is shown in Fi ure 4.2 below.
The pin layout of the 24 VDC connector of
BX11 Series
( rear view )
0V 24V
Figure 4.2 - The pin layout of 24VDC connector
The quality of the instrument’s round will determine the accuracy and the safety of your measurin system.
A proper round connection is needed to minimize extraneous electrical noise affects on the measurement.
A poor round can result in an unsafe and unstable operation. It is important that the instrument should not
share power lines with noise- eneratin parts such as heavy load switchin relays, motor control
equipments, inductive loads, etc. If the condition of the power line in the plant is poor, prepare a special
power line and roundin .
Before interferin the instrument, turn off the power and wait at least for 30 seconds.
Warning: onnect the Shield pin to the reference ground.

4.3.2 Load Cell Connection
To avoid dama es, the load cell wirin should be made carefully before ener izin the instrument. Load cell
connection detail is shown in Fi ure 4.3. In 4-wire installations the sense and excitation pins with the same
polarity should be short circuited at the connector side. If you have junction box, use 6 wire cable between
BX11 and the junction box, and short circuit these pins at junction box for better performance.
4 wire LC connection
6 wire LC connection
Figure 4.3 - Load cell connections
Warning: Always connect Sense pins to Excitation pins for 4 wire connection. Non-connected sense pins
may cause the wrong Excitation voltage measurement and create an accuracy problem.
Warning: onnect the load cell cable shield to the reference ground or shield pin of the load cell connector.

Table 4.2 - RS 485 Serial Interface Specifications
RS 485 serial connection is done with three wire as indicated below in Fi ure 4.5. Line termination resistors
( 110 ohm ) are needed both ends of the RS 485 line.
Figure 4.5 – RS 485 serial interface connections
Warning: onnect the shield to the reference ground.
Warning: Disconnect IndFace1X P software before starting Modbus-RTU interfacing.
