Cleaning
Do not clean the instrument while the instrument is on.
Harsh abrasives, solvents, scouring cleaners and alkaline
cleaning solutions, such as washing soda, should not be
used especially on the display window. The outside of the
instrument may be wiped down with a slightly damp clean
cloth (lightly moistened with water only).
Under no circumstances should you attempt to wipe the
inside of the instrument.
Safety
This equipment is supplied by a mains voltage which can
cause an electric shock injury. Before removing the circuit
board from its housing, switch the instrument off, isolate it
from the mains power supply and make sure that it cannot
be connected inadvertently by other persons.
If the circuit board is removed from its housing, do not
apply power to the instrument unless specifically instructed
to do so in these instructions. When working on live
equipment, exercise great care, use insulated tools and test
equipment, and do not work alone.
When fitting option boards, always put the circuit boards
back in the housing with the back-plate securely fastened
before powering up the instrument.
When handling circuit boards, ensure that full anti-static
precautions are observed.
Replace external mains fuse with one of an equivalent type.

The load cell can be pre-calibrated by entering the zero and load cell full scale capacity in the programming menu. The load cell
system zero value can normally left at 0 for the pre-calibration. The load cell full scale capacity is then entered.
Example 2:
For a 3 x 1000 kg load cell system with 2mV/V each.
Carefully remove the circuit board from the housing and link for
2mV/V on jumper J4 (see step 1 above).
Program the instrument as follows:
- Go to the “Inp” and “Cal” menu.
- Set “2 mV” which represents the load cell sensitivity.
- Set decimal point to “oooo” (no decimal point).
- Set load cell “zero” to “0”.
- Set "LC.FS" to "3000" (as there are 3 x 1000 kg load cells).
The system has now been pre-calibrated.
Setup Procedure & Calibration
REFER TO THE PROGRAMMING FLOW CHART on page 10 while using this setup procedure.
This instrument offers an easy & straightforward way to pre-calibrate and field calibrate the load cell system. Follow the steps below:
Step 1 : Setting instrument sensitivity
The load cell sensitivity must be set in via jumper link J4 on the circuit board (see circuit board layout diagram on page 6). The
sensitivity setting must also be set in the programming menu (use the programming chart on page 10 to assist you, as well as the
examples below). If the load cell system sensitivity is not exactly one of the pre-determined ranges of 1mV/V, 2mV/V, 3mV/V or
10mV/V, then use the next highest sensitivity. E.g. if the load cell sensitivity is 1.6mV/V, then use the 2mV/V range. Remember to set
the sensitivity link (J4) on the circuit board as well.
See example 1 and 2 below.
Example 1:
For a 1 x 5.000 ton load cell that has a 3mV/V sensitivity.
Carefully remove circuit board from the housing and link for
3mV/V on jumper J4 (see step 1 above).
Program the instrument as follows:
- Go to the “Inp” and “Cal” menu.
- Set “3 mV” which represents the load cell sensitivity.
- Set decimal point to "o.ooo” (three decimal places).
- Set load cell "zero" to "0.000".
- Set load cell full scale capacity "LC.FS" to "5.000".
The instrument has now been pre-calibrated.
Step 2 : Entering the decimal point, the load cell zero, and the full scale capacity value
Page 9

Once steps 1 - 4 above have been completed, the instrument automatically alters the pre-calibration parameters “Zero” and “LC.FS”
in the “CAL” sub-menu (entered in step 2 above). These altered parameters may not resemble the original values entered by the user.
This is normal as these parameters fully characterise the weighing system.
DO NOT change these parameters. It is suggested that these parameters be noted for future use, especially if the instrument is
replaced. These parameters can be re-entered into the new instrument with the result that reasonable accuracies can still be obtained
without re-doing a field calibration. This is especially useful when minimum downtime is critical, and to avoid wastage if failure occurs
when the bin / hopper still contains materials. It is still recommended that complete field calibration is done when the situation permits.
Step 5 : Store away calibrated instrument parameter for future use
Make sure that steps 1 & 2 on the previous page have been completed before proceeding with step 3.
The following procedure removes the deadweight from the weighing system (which is normally the bin / hopper / scale weight), and
returns the display reading to show zero with the bin empty.
Make sure that the bin / hopper is empty. Use the programming chart to go to “Inp”, followed by “Tare”. Press enter. The display will
flash “Tare” indicating that the instrument is measuring and averaging the bin weight. Allow for a few seconds of averaging, then press
the enter (star) button to stop the process. The instrument will exit programming mode and the display should read zero.
Step 3 : Field calibration of load cell system for back-balance (deadweight)
Make sure step 3 above has been completed before proceeding with step 4.
The following procedure allows the weighing system to be accurately calibrated using test weights.
Place the test weights on the bin / hopper / scale. The instrument should read the weight of the test weights. If the reading is not of
sufficient accuracy, then use the programming chart to go to "Inp", followed by "LOAD" and press enter. The instrument now prompts
you to enter the weight of the test weights. Then press enter. The display will flash “LOAD” for a few seconds, indicating that the
instrument is measuring and averaging the tests weights in the bin / hopper / scale. The instrument automatically exits programming
mode after a few seconds.
Step 4 : Field calibration of span (test weight calibration)

IGNORE THIS PAGE unless communications option has been ordered. When the RS232 (option 3013) or RS485 (option 3002) is
ordered, two protocols are made available, namely ASCIIbus & DIGIbus protocols. DIGIbus is the default protocol which is used for
the calibration and configuration of the instruments, and whenever the instrument is connected to master-slave systems. DIGIbus
protocol is therefore used in complex bus systems, and is NOT described here. Please contact factory for the DIGIbus protocol.
ASCIIbus, which is described here, is much easier to use as it can easily interface to third party systems with very little engineering
work required. It is a purely ASCII based (7 bit) protocol. The protocol is essentially designed for one way communications
(instrument to PC). Under the "Conn" (connection) programming menu, ASCIIbus is enabled by selecting "ASCI" to "ON". If "OFF" is
selected, the DIGIbus protocol will be active. Although designed for one way communications only, the ASCIIbus protocol contains an
address. The address range is "00" to "99".
Using address "00" : If this address is selected, the instrument will only transmit data on demand by either momentarily pressing the
'menu' key, or by transmitting a byte (any ASCII character) to the DPM. This mode is useful for interfacing to printers. In addition, field
' A A ' will contain the ASCII character "blank/space". Field ' P ' will also contain the ASCII character "blank/space".
Using address "01" to "99". If any of these addresses are used, the meter continuously transmits information at approximately 5 times
a second.
The data format string output from the indicator is (7 bit ASCII code is used):
Line Settings : 7 Data Bits, 1 Parity bit, Odd Parity, 1 Stop Bit.
Baud Rate : Selectable 2400, 4800, 9600, 19200.
Data Bits : Numerical ASCII characters : 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
Other ASCII characters : #, blank/space, +, -, CR, LF
Protocol format is : # A A S D D D D D D D D P CR LF
where : # = indicates start of message
: A A = Instrument address. ASCII 00 to 99. 00 is default.
: S = sign (polarity) ( ASCII "+" or "-" ).
: D = data bits (data for 8 numerals). See Note (1).
: P = decimal point position. ASCII 0 to 8.
: CR = ASCII carriage return.
: LF = ASCII line feed.
The output will follow the display reading. This
means that if the peak-hold option has been
ordered and activated, the communications output
will peak-hold as well.
Note 1 : This protocol allows for future expansion.
Therefore if Model 4001 is used for example, the
first four digit data will contain the ASCII character
"blank/space" and the last four digits will contain
the display reading. Similarly, if the Model 5001 is
used for example, the first 2 digit data will contain
the ASCII character "blank/space" and the last six
digits will contain the display reading.

The lineariser option is used for non-linear input signals. A 16 point straight line approximation lineariser is provided. The user can enter any number of
points from 2 (Linear input signals) to 16. The greater the number of points, the greater the accuracy of the linearisation. Every actual display point has a
corresponding linearised display point.

NOTE:
- If the input signal is beyond the limits of the last actual point entered then the unit will calculate the slope between the last 2 actual values and
use this to calculate the required linearised display.
- Do not enter the same actual value for 2 or more points. The unit will compare and select the first sequential point in memory and use this.
- The lineariser points is a mirror image for negative input signals.
SETUP:
- The instrument must be setup and calibrated as instructed in the manual.
- The user must then apply test signals and record the actual readings on the display.
- The user must then activate the lineariser and enter the actual reading with the
corresponding desired reading.
- The instrument can be checked by applying the original test signals and verifying the
display.

See page 7 for connection details. However, if option 3002 / 3013 is also fitted, then the relays are fitted on an option board that slots
into the upper slot of the panel meter box (terminals numbered 13-28). See diagram “P” on page 20 for the relay connections. Wire for
AL1 only.
One Setpoint Alarm (Electro-Mechanical Relay)Option 3004-M
One Setpoint Alarm (Solid State Relay)Option 3004-P
This option is similar to option 3001-M described above, but offers one alarm relay only. See option 3001-M above for more
information, but wire for AL1 only.
This power supply option provides 8 - 30V DC supply isolated. See page 7 for connection details. This option also provides excitation
for up to four load cells.
Galvanic Isolation (8 - 30V DC Supply) OptionOption 3008
Parallel BCD Output OptionOption 3009
This option is supplied as an additional slot-in card in the top part of the instrument housing. See the additional documentation. Note
that this option cannot be used in conjunction with any of the alarm setpoint options, nor with the bar graph display option.

See the additional documentation supplied for protocol details & page 7 for connection details. Ensure that maximum cable length
from instrument to PC is less than 15 metres.
RS232 Communications OptionOption 3013
This options allows the instrument to operate from a wide range of AC & DC power supplies. The supply connections are on page 7.
This option also provides excitation for up to four load cells.
Peak Or Valley (Max or Min) Hold OptionOption 3012
95V-265V AC / DC Power Supply OptionOption 3010
This option displays and holds the maximum or minimum value (not both) of an input signal. This option is activated in the
programming menu “Opt” by selecting whether “Hold” should be “On” or “Off”, and selecting whether valley (”valy” = “On”) or peak
(”valy” = “Off”) hold should be displayed.
The display can be toggled to show the peak / valley value or normal value by toggling the “up” arrow key (press for about 3 seconds
each time). For rapid response to step changes on the input, ensure that the filter in the programming menu is set to 0.0. To reset the
peak / valley hold value, press the “side” arrow key for 3 seconds, or use an external potential free contact (see page 7 for connection
details). If analog output option is fitted, the output will hold as well.
This option allows the operator to zero the display at any time and continue the measurement from that point in time. This option is
activated "ON" or "OFF" in the "Opt” menu during programming (see page 10).
During normal operations, pressing the “star key” for 3 seconds will zero the display. The display can also be zeroed via an external
potential free contact (see page 7 for connection details). The display can be zeroed at any time over and over again.
If the analog output option is fitted, the output will follow the display.

Three Alarm Setpoints (Electro-Mechanical Relays)Option 3017-M
This option provides three alarm setpoints with solid state relays. This option board slots into the upper slot of the panel meter box.
The upper terminals are clearly numbered 13-28 to differentiate them from the lower terminals. Only normally open contacts are
provided, which means that should the contacts be closed and the power fails, they will revert to a normally open condition. The
relays are rated at 400V AC /DC @ 0.5A. Visual LED alarm indication is provided on the panel meter front. For connection wiring
details, see diagram “P” on page 20. Connect wires for AL1, AL2 & AL3 only.
