3.1 Introduction
This document describes the use of the Alfa Laval Weighing system equipped with the analogue output module
TE67X000002029.
With the program specified on the front page, the TE67X000002029 analog module is capable of transmitting the
weight for a system with up to 8 load cells as an analog 4-20 mA signal (or 0-10V depending on factory settings).
Each load cell is connected to the TE67X000002029 analog module through a load cell interface module
TE67N000002010.
Note: The illustrations and specifications contained in this manual were effective at the date of printing. How-
ever, as continuous improvements are our policy, we reserve the right to alter or modify any unit specification
on any product without prior notice or any obligation.

4) TE67X000002010 DESCRIPTION
Below the layout of the TE67X000002010 load cell module is shown. Before using the system the load cells must
be connected to the load cell modules.
Please notice that the load cell and the load cell module MUST be marked with the same year/serial number.
These are printed on the type-plate of the load cell and on a small sticker placed below the BNC plug on the load
cell module. Load cells and load cell modules MUST NOT be intermixed because the program in each load cell
module is SPECIALLY adapted to one load cell only (and only this load cell). The load cell module MUST be con-
nected to exactly the load cell it is intended for and vice versa.
The load cell modules are connected to each other using the supplied cable (10 pole ribbon cable). The
TE67X000002029 analog module is connected using the same cable.
All switches (SW1) in the load cell module must be at the correct position before use.
Please notice that the switches (SW1) are only read once during power-up. If a change in the switch setting is
necessary the power has to be disconnected and then reconnected (after 10 seconds). Then the
TE67X000002010 load cell module recognizes the new switch setting.

Switch SW1.5 to SW1.8 are used for address selection. All load cell modules must have unique addresses as-
cending from 0 with no gaps unless expressly specified otherwise. No addresses may be skipped and no ad-
dresses may be used by more than one load cell module. In systems with 1-8 load cells switch SW1.5 must be set
to OFF.

5) TE67N000002029 Description
5.1 Display, lamps and keyboard
This section describes the use of a TE67X000002029 analog module from Alfa Laval, when equipped with the
program listed on the front page.
With the program specified on the front page, the TE67X000002029 analog module is capable of transmitting the
weight for a system with up to 8 load cells as an analog 4-20 mA signal (or 0-10V depending on factory settings).
Each load cell is connected to the TE67X000002029 analog module through a load cell interface mod-
ule.(TE67N000002010) By use of DIP switches it is possible to include one of 3 different FIR filters, which will be
used to filter the weight signal.
The control lamps have the following functions:
TXBB (Green) Lit when communicating with the connected load cell modules.
D1 (Yellow) Lit when a key is activated.
AN.ERR. (Red) Lit when the analog output signal is different from its programmed value.
The 5 keys have the following functions:
”F” Cyclic change between different display modes etc.
”Up” Increments desired value etc.
”Down” Decrements desired value etc.
”Esc” Regret desired value etc.
”Enter” Accept of selected display value etc. This key must be pressed in order to accept
any change of parameter
The ”F” key can be used to change between different display modes. In a given mode the display will alternately
show ”XXXXXX” and ”YYYYYY”. Here ”XXXXXX” will be a text indicating the actual mode, while ”YYYYYY” will
indicate the actual value belonging to this mode.
By holding down the ”F” key and then pressing ”Esc” the LoAd” mode is selected.
If during power-on the display shows ”Par.SEt.”this is because parameters have to be set. The ”F” key can then
be used to proceed to “LoAd” mode and the chapter describing ”Err.rEg.” mode can be used for further informa-
tion.
If at any time the display shows ”-OL-”(OverLoad) or ”-UL-”(UnderLoad) this is because the actual value to be
shown in the display is too large/small.

5.2 Display modes
It is possible to select between the following modes:
MODE FUNCTION
”LoAd” used during normal operation for display of gross weight.
”OutPut” used for display of the actual analog output signal.
”PASS” used during selection of password.
”ZEro” used during zero of the weight indication.
”CAL.L.” used during calibration of the weight indication.
”CAL.” used during calibration of the weight indication.
”CAL.F.” used to calculate the calibrated weight indication.
”n.Lc.” used to indicate number of loadcells.
”n.Crn.” used to indicate number of corners (supporting points).
”Int.PEr.” used to indicate integration period (measurement time).
”Unit” used to set desired weighing parameters (unit).
”dPno” used to set desired weighing parameters (decimal point position).
”div” used to set desired weighing parameters (division).
”SP. 1” used to control digital output 1.
”SP. 2” used to control digital output 2.
”An.SP.” used to indicate weight value for full analog output signal.
”An.Err.” used to set analog output signal used during status code indication.
”An.tyPE.” used to select signal transferred on the analog output.
”rS485” used to select signal transferred on the serial RS485 channel.
”dAc.tSt.” used to test the analog output signal.
”LC x ” used to show loadcell status/signal for loadcell x (0-7).
”Err.rEg.” used to show various error codes.
5.2.1 LoAd mode
This mode is used during normal operation to show the actual gross weight. The weight indication is indicated in
gram, kg or ton depending on the selected weighing parameters (”Unit” , ”dPno” and ”div”). If the
TE67X000002029 analog module detects a situation that results in a status code indication different from 0, the
display will show the status code as “-xxxx-“ instead of the weight indication, and it will output its error value (see
”An.Err.” mode) on its analog output for the duration of this situation.
5.2.2 OutPut mode
This mode is used for indication of the actual analog output signal. The analog output signal is shown in mA/V
depending on the hardware configuration of the TE67X000002029 analog module.
5.2.3 PASS mode
This mode is used to select password. To avoid unintended change of parameters the module is equipped with a
password. To change parameters, zero or calibrate the weight indication from the keyboard the user has to set the
actual password so that it equals ”1357”. Hereafter the ”Enter” key is pressed to accept the value.
Remember to clear the password in the same fashion when done.

Instruction Manual IM-TE91K010-EN4 Page 9
System with digital load cells
Version: 2012-06-12, rev.:0a
5.2.4 ZEro mode
This mode is used during zero of the weight indication (gross weight). The zero should only be done with an empty
and clean weighing platform. The display shows the actual weight as in ”LoAd” mode. The weight indication is
indicated in gram, kg or ton depending on the selected weighing parameters (”Unit” , ”dPno” and ”div”). If the
TE67X000002029 analog module detects a situation that results in a status code indication different from 0, the
display will show the status code as “-xxxx-“ instead of the weight indication, and it will output its error value (see
”An.Err.” mode) on its analog output for the duration of this situation.
The zeroing is performed by pressing ”Enter”, if the correct password has been selected. A zeroed and empty
system will cause the analog output signal to go to its minimum value (4mA or 0V). Note that on a
TE67X000002029 analog module running in current configuration, the analog output signal can go below 4mA for
negative weight indications.
The zeroing can also be made using the digital input IN1. Zeroing using the digital input IN1 can be performed
regardless of password value and the selected display mode.
5.2.5 CAL.L. mode
This mode is used during calibration of the weight indication. The display shows the desired calibration load to be
used during calibration. The calibration load is indicated in gram, kg or ton depending on the selected weighing
parameters (”Unit” , ”dPno” and ”div”). The calibration itself is performed in ”CAL.” mode.
5.2.6 CAL. mode
This mode is used during calibration of the weight indication. The display shows the actual gross weight. The
weight indication is indicated in gram, kg or ton depending on the selected weighing parameters (”Unit” , ”dPno”
and ”div”). If the TE67X000002029 analog module detects a situation that results in a status code indication differ-
ent from 0, the display will show the status code as “-xxxx-“ instead of the weight indication, and it will output its
error value (see ”An.Err.” mode) on its analog output for the duration of this situation.
Calibration of the gross weight to match the calibration load entered in ”CAL.L.” mode is performed by pressing
”Enter”, if the correct password has been selected. The complete calibration procedure for calibration is described
later.
5.2.7 CAL.F. mode
This mode is used during reading/adjustment of the calibration factor. The calibration factor is changed after each
performed calibration and should be noted so that it is possible to re-establish the calibration. The calibration factor
can be changed directly if the correct password is selected. The calibration factor lays in the interval 104858 to
943718 with 524288 as the standard calibration factor (corresponding to no calibration). By changing the calibra-
tion factor within this interval it is possible to change the weight indication with ±80%. The procedure for calibration
is described below.
5.2.8 N.Lc. mode
This mode is used during installation to indicate the number of load cells (1-8) connected to the TE67X000002029
module. As an example, the ”n.Lc.” parameter should be 1 in a system consisting of a three legged tank, where
only one corner contains a load cell. Note that changing the ”n.Lc.” parameter will clear the ”SP. 1” , ”SP. 2” ,
”An.SP.” and the ”CAL.L.” parameters. If a change is made to this parameter, it may be necessary to turn the
power off and on for the change to take effect.
5.2.9 N.Crn. mode
This mode is used during installation to indicate the number of corners (supporting points) (1-8). Note that it is the
total number of supporting points including corners supported by load cells. As an example, the ”n.Crn.” parameter
should be 3 in a system consisting of a three legged tank. Note that changing the ”n.Crn.” parameter will clear the
”SP. 1” , ”SP. 2” , ”An.SP.” and the ”CAL.L.” parameters.
5.2.10 Int.PEr. mode
This mode is used during installation to indicate the integration period (40ms, 100ms, 200ms, 400ms, 1000ms,
2000ms or 4000ms). This determines the time over which the load cell(s) are sampled to determine a new weight
reading, and thereby how often the analog output signal is updated.

Page 10 Instruction Manual IM-TE91K010-EN4
System with digital load cells
Version: 2012-06-12, rev.: 0a
5.2.11 Unit mode
This mode is used during installation to select the desired unit used when presenting weight indications in the
display. The unit can be set to gram, kg or ton. Note that changing the ”Unit” parameter will clear the ”SP. 1” , ”SP.
2” , ”An.SP.” and the ”CAL.L.” parameters.
5.2.12 dPno mode
This mode is used during installation to select the desired decimal point position used when presenting weight
indications in the display. The decimal point position specifies the number of digits following the decimal point, and
it can be selected from a range of predefined values. Note that changing the ”dPno” parameter will clear the ”SP.
1” , ”SP. 2” , ”An.SP.” and the ”CAL.L.” parameters.
5.2.13 div mode
This mode is used during installation to select the desired resolution used when presenting weight indications in
the display. The resolution (or division) can be selected from a range of predefined values. Note that changing the
”div” parameter will clear the ”SP. 1” , ”SP. 2” , ”An.SP.” and the ”CAL.L.” parameters.
5.2.14 SP. 1 and SP. 2 mode
This mode is used to set the two set points (SP1 and SP2) that are used for controlling the two level alarms im-
plemented on digital outputs OUT1 and OUT2 as described later. The set points are indicated in gram, kg or ton
depending on the selected weighing parameters (”Unit” , ”dPno” and ”div”).
5.2.15 An.SP. mode
This mode is used during installation to indicate the weight value that should result in maximum analog output
signal (20mA or 10V). The analog set point that results in maximum analog output signal is indicated in gram, kg
or ton depending on the selected weighing parameters (”Unit” , ”dPno” and ”div”).
5.2.16 An.Err. mode
This mode is used during installation to indicate the analog value (0-20mA or 0-10V) that is transferred on the
analog output when status indication is different from 0.
5.2.17 An.tyPE. mode
This mode is used during installation (or error finding) to indicate what signal type is used to determine the signal
on the analog output. ”LoAd” can be selected causing the analog output signal to follow the gross weight indica-
tion in ”LoAd” mode. Alternately ”Lc 0” - ”Lc 7” can be selected causing the analog output signal to follow one of
the loadcell signals in ”LC x” mode. During normal circumstances the parameter should be set to ”LoAd”.
5.2.18 rS485 mode
This mode is used during installation (or error finding) to indicate what signal is transferred on the serial RS485
communication channel. ”LoAd” can be selected causing the gross weight indication in ”LoAd” mode to be trans-
ferred. Alternately ”Lc 0” - ”Lc 7” can be selected causing one of the loadcell signals in ”LC x” mode to be trans-
ferred. During normal circumstances the parameter should be set to ”LoAd”.
5.2.19 dAc.tSt. mode
This mode can be used to test the analog output signal. Once the ”dAc.tSt.” mode is entered the display will show
“OFF” indicating that the analog test mode is disabled. To enable the analog test mode the ”Enter” key must be
pressed.
When the analog test mode is enabled, the display will show an analog test value that is sent out on the analog
output. NOTE that this value overrides the normal analog output signal (based on the actual gross weight) for as
long as the analog test mode is enabled. When the analog test mode is enabled, it is possible to change the ana-
log test value by using the ”Up” or ”Down” key. Thus it is possible to set different values from 0mA (or 0V) to
20mA (or 10V) in increments of 1mA (or 0.5V).
The analog test mode is disabled by pressing the ”Esc” key when still in ”dAc.tSt.” mode. The analog test mode is
also automatically disabled once the ”dAc.tSt.” mode is left by pressing the ”F” key. Once the analog test mode is
disabled, the analog output signal will be controlled by the actual gross weight once again.

Version: 2012-06-12, rev.:0a
5.2.20 LC x mode
This mode is used to show the status or signal from load cell x. Thus it is possible to read the status/signal of all
connected load cells. If no error is present on the selected load cell, the display will show the weight indication
measured on that load cell. The weight indication is indicated in gram, kg or ton depending on the selected weigh-
ing parameters (”Unit” , ”dPno” and ”div”). If the TE67X000002029 analog module detects a situation that results
in a status code indication different from 0 for the selected load cell, the display will show the status code as “-
xxxx-“ instead of the weight indication.
5.2.21 Err.rEg. mode
If the TE67X000002029 analog module detects an error a corresponding error code can be read in this mode. If
present these errors are normally detected upon power up, causing the TE67X000002029 analog module to pro-
duce a ”PAr.SEt.” message. In this situation, pressing the ”F” key will cause the module to enter ”LoAd” mode
without clearing the error. The error can then be examined in the “Err.rEg.” mode for further information.
Please refer to the table describing the error codes for the cause and a possible solution.
Please note that these errors differ from the status codes that can be shown in the ”LoAd” , ”ZEro” and ”CAL.”
modes. Also these error codes will NOT result in a error signal (see ”An.Err.” mode) on the analog output.

5.3 Level alarms
The 2 digital outputs on the TE67X000002029 analog module can be used as level alarms.
Set points for the two alarms are set using the ”SP. 1” or ”SP. 2” modes.
The following applies to the two level alarms:
Level alarm 1:
The alarm is implemented on the OUT1 output.
The level of activation is selected in the ”SP. 1” mode.
The alarm is active BELOW SP1.
The alarm is active if the status code differs from 0.
Level alarm 2:
The alarm is implemented on the OUT2 output.
The level of activation is selected in the ”SP. 2” mode.
The alarm is active ABOVE SP2.
The alarm is active if the status code differs from 0.
5.4 Filtering
By use of DIP-switches it is possible to include one of 3 different FIR filters, which will be used to filter the weight
signal. Thus it is possible, to send the unfiltered gross weight achieved over each integration period (Tavg) through
one of the following FIR filters, before the result is displayed and send to the analog output:

5.5 RS485 serial communication
The TE67X000002029 analog module communicates on its RS485 communication channel using the following
serial parameters:
Baudrate: 9600 bps
Data bits: 8
Parity: None
Stop bits: 1
The TE67X000002029 analog module transmits status and measured weight every measurement period on its
RS485 channel (9 pole sub-D connector) based on what has been selected in ”rS485” mode.
If ”LoAd” is selected the contents of the transmitted telegram is:
<Status> , <Load> <LF> <CR>
If ”Lc 0” - ”Lc 7” is selected the contents of the transmitted telegram is:
<LcStatus[x]> , <LcSignal[x]> <LF> <CR>
where:
-<LF> is a line feed character.
-<CR> is a carriage return character.
-<Status> is the status code as shown in the ”LoAd” menu. This is a 4 character long hex number and should
be 0000 during normal error free operation.
-<Load> is the gross weight as shown in the ”LoAd” menu. This is a 6 character long value. Note that this field
will be 7 characters long if a decimal point is used.
-<LcStatus[x]> is the status code as shown in the ”LC x” menu. This is a 4 character long hex number and
should be 0000 during normal error free operation.
-<LcSignal[x]> is the loadcell signal as shown in the ”LC x” menu. This is a 6 character long value. Note that
this field will be 7 characters long if a decimal point is used.

8) TROUBLE SHOOTING
8.1 Status code indication
If the TE67X000002029 analog module detects a situation that results in a status code indication different from 0,
the TE67X000002029 analog module will output its error value (see ”An.Err.” mode) on its analog output, and the
level alarms will both be active, no matter what the current load is. As described earlier the actual status code will
then be shown instead of the actual gross weight in the ”LoAd” , ”ZEro” and ”CAL.” modes. It will then be possible
to use the ”LC x” modes to try and locate the error.
8.2 Error code indication
If the TE67X000002029 analog module detects an error a corresponding error code can be read in the ”Err.rEg.”
mode as described earlier.
If present these errors are normally detected upon power up, causing the TE67X000002029 analog module to
produce a ”PAr.SEt.” message. In this situation, pressing the ”F” key will cause the module to enter ”LoAd” mode
without clearing the error. The error can then be examined in the “Err.rEg.” mode for further information.
Please refer to the table describing the error codes for the cause and a possible solution.
Please note that these errors differ from the status codes that can be shown in the ”LoAd” , ”ZEro” and ”CAL.”
modes. Also these error codes will NOT result in a error signal (see ”An.Err.” mode) on the analog output.
8.3 Analog output error
If the build-in DA-converter detects that the analog output signal is different from its programmed value, the
”AN.ERR.” light emitting diode will be lit. This will for example be the case if the current-loop is broken in a system
where the module is in its current configuration.

9) INSTALLATION OF SYSTEM
9.1 Checklist during installation
During installation of the system the following should be checked/performed:
1) The load cells are mounted mechanically and connected to the TE67X000002029 analog module using their corresponding load
cell interface module. The load cell addresses are set using the DIP-switches on the load cell interface modules, so that they forth
running from address 0 (0-7).
2) Check that the RS485 channel, the digital I/O and the analog connections of the TE67X000002029 analog module are made as
described in the hardware description.
3) Select the desired filter using the DIP switches (Sw2.3-Sw2.4). Power is applied.
4) Verify that the green TXBB LED on the TE67X000002029 analog module is lit and that the TXBB LED’s on the load cell interface
modules are also lit (can flash slightly). Also verify that other LED’s on the load cell module behave as expected.
5) Verify that no “PAr.SEt.” message is produced at power-up. Upon power-up the TE67X000002029 analog module will automati-
cally produce this message if errors are detected, or enter the “LoAd” mode if no errors are detected. Refer to the chapter de-
scribing error codes on how to solve/remove errors.
6) Verify that the red AN.ERR LED on the TE67X000002029 analog module is OFF.
7) Select “PASS” mode (using the “F” key), set the password to 1357 (using the arrow keys) and accept the value (using the “Enter”
key).
8) Select “n.Lc.” mode and set the number of load cells connected to the TE67X000002029 module. If a change is made to this
parameter, it may be necessary to turn the power off and on. Remember to set the password to 1357 once again, if power is
turned off and on, and further settings have to be made.
9) Select “n.Crn.” mode and set the number of corners (supporting points).
10) Select “Int.PEr.” mode and set the desired integration period (40ms, 100ms, 200ms, 400ms, 1000ms, 2000ms or 4000ms).
11) Verify that the TE67X000002029 analog module has found the correct number of load cells and that no status codes (load cell
errors) are indicated. The “Lc X” modes may be used to locate the origin of any errors present.
12) Select proper weighing range parameters using the “Unit” (unit), “dPno” (decimal point position) and “div” (division) modes. The
weighing range parameters should match/reflect the actual weighing system and its capacity.
13) If the two level alarms implemented on digital outputs OUT1 and OUT2 are to be used set their controlling setpoints using the “SP.
1” and “SP. 2” modes.
14) Select “An.SP.” mode and set the load corresponding to 20mA (or 10V).
15) Select “An.Err.” mode and set value (0-20mA or 0-10V) transferred on the analog output when status code indication is different
from 0.
16) Select “An.tyPE.” mode and check that “LoAd” is selected, so “LoAd” mode determines the analog signal.
17) Select “rS485” mode and check that “LoAd” is selected, so “LoAd” mode determines the signal on the RS485 channel.
18) Select “ZEro” mode, and with an empty weighing system zero the system by pressing “Enter”.
19) Perform a calibration of the system as described below.
20) Select “OutPut” mode and verify using an instrument that the physical analog output signal behaves as expected depending on
the actual load. If desired the “dAc.tSt.” mode can be used in addition to manually generate different analog test signals.
The system is now installed and a final zero can be made before the password is cleared (set to 0 and press the
“Enter” key) and the module is set to “LoAd” mode.

9.2 Calibration procedure
Calibration of the TE67X000002029 analog module and the connected load cells is made using the following pro-
cedure:
1. Allow calibration by selecting the correct password (1357) in ”PASS” mode.
2. Check that the weighing arrangement is empty and clean.
3. Zero the system using ”ZEro” mode.
4. Check that the weight indication is zero. Zero again if necessary.
5. Place the calibration load on the system. The load should be as close to the maximum load as possible. In
order to achieve a correct calibration of the system it is recommended, that the used calibration load is at least
50% of the system capacity.
6. Select ”CAL.L.” mode and set the calibration load to match the applied load
7. Select ”CAL.” mode and calibrate the system by pressing the ”Enter” key. Hereby the calibration factor is
changed so that the weight indication matches the actual load. This is verified in ”LoAd” mode. Note that it is
only possible to calibrate within an interval of ±80%. If this is not enough, the mechanical part of the system
should be checked, since this is most likely the cause to the problem.
8. Select ”CAL.F.” mode and note the achieved calibration factor, so that the calibration can be re-established
later.
9. The system is calibrated and the calibration should be protected by clearing the password (set to 0). Select
”LoAd” mode and verify that a given load results in a matching weight indication.
The weight indication can also be calibrated directly by changing the calibration factor in ”CAL.F.” mode. The fol-
lowing relationship between calibrated indication, uncalibrated indication and the calibration factor applies:
WeightCAL.= [(CALFAC) / 524288] * WeightUNCAL.
Note that the standard calibration factor of 524288 results in no calibration.
