IN RODUC ION
Features
Basic
Units & Resolution
The units for each variable type (weight etc.) can be selecte from a list of metric an imperial units.
The resolution of each variable type can be a juste , this alters the count by e.g 100kg isplaye in
0.2kg increments.
OIML Design
The instrument is esigne to OIML stan ar s.
Language Support
Support is available for the following languages: English, Chinese, Korean, German, Spanish, French,
Italian an Polish.
Inputs
Digital Inputs INx
The igital inputs are programmable to a range of function inclu ing ‘acquire zero’, ‘print’ etc.
Direct Calibration
Direct calibration uses the loa cell capacity an loa cell sensitivity to calibrate the weight signal. Large
capacity weighing systems can be quickly an accurately calibrate without the nee for large test
weights.
Corner Adjustment (M 1 only)
The input sensitivity can be in ivi ually a juste for up to 4 loa cells, allowing ifferences in loa cell
sensitivities to be correcte .
Four Loadcell Inputs (M 1 only)
Separate inputs are available for 4 loa cells allowing the signal of each to be monitore sperately. This
provi e an ai for loa balancing across loa cells an also for fault fin ing.
Zeroing/ aring
The ZERO an TARE keys allow the weight rea ing to be set to zero. The SET TARE key allows a man-
ual tare weight to be entere .
Signal Filtering
Filtering for the weight can be a juste to get the optimum compromise between re uction of plant vi-
bration an response spee .
Internal Signals
Limits
The high an low limits have a justable setpoints which may be programme to operate on any internal
signal.
Event Collection
Process events are collecte for operation with external equipment (PLCs etc.)
otal Weight
The isplaye weight can be a e to a running total. The total can be reset at any time.
Peak Weight
A peak weight rea ing is maintaine of the highest absolute value of the weight measure . The peak
value can be reset to 0.
Memory Storage
Allows a group of settings to be store or recalle from memory. This can be use for example to store
settings for ifferent pro ucts. There are 20 memory locations with up to 4 settings in each.
Outputs
Analog Outputs AO1 & AO2
A 4-20mA output normally of weight may be programme to be any of the internal signals inclu ing
isplaye weight, gross weight an net weight.
Analog I/O Scaling
The analog output range can be a juste over the full 0 to 20mA range. The output will rive to a slight
negative mA, allowing a live zero to be achieve when using a 0 to 20mA range. A voltage output is
easily pro uce by connecting a resistor to the output.
In a ition the analog output signal is selectable to come from any internal signal in the instrument e.g
weight, flowrate etc.

EMC INDUS RIAL GROUP L D Specifications
MW61A_IM_ALL_SV6.09d_en 6/47
Digital Outputs OU x
The igital outputs are programmable to operate from any internal signal. These signals inclu e the
igital input states, status con itions (running, pause etc) an any fault con itions that are etecte .
This makes it easy connect into other systems.
Communications & Display
Comms
RS232 an RS485 ports are available. These are use to connect Mo Weigh units together an also to
connect to other systems. The protocol is either ASCII output for example to rive a printer or Mo bus
for interactive communications. Bau rates an no e a resses are programmable.
USB host an evice ports are available. This allows for example PC an USB flash rive connectivity. It
can be use to up ate the units software, for ata logging an for recor ing of the units settings.
Printouts & Macros
Printouts can be triggere by a key press or set up to occur at set times uring the ay or week. Data
may also be output continuously for ata collection purposes. Data is output on the COM1 RS232 port.
The content of the printouts is fully programmable using Macros.
Macros are programs use to customise printouts, but can also be use to perform arithmetic calcula-
tions. The Macro language also contains con itional terms for more a vance programming.
Display Customisation
Locks may be set to prevent unauthorise use of the operator keys an restrict entry to the operator
menu. The keys are in ivi ually lockable an optionally a passco e can be use to allow authorise op-
erators to use the keys. Alternatively a confirmation of the key action can be requeste .The operator
MENU can be customise to make a itional settings or signals available to the operator.
The contents of the main isplay can be set to suit any con ition, from a comprehensive isplay show-
ing all operating parameters to a simple isplay showing the basic signals.
Computer Connectivity
Mo Weigh instruments can be connecte to a computer withan RS232 connection. Data can be sent to
the PC at a preset rate. The ata sent can be set up using macros.
There is also a comman line interface which allows any of the settings an ata to be rea or written.

The loa cell(s) may be wire irectly to the loa cell terminals or connecte together in the fiel with a
junction box an connecte to the Mo Weigh unit with a single cable.
When connecte to the terminals only a 4-wire connection is use , an igital corner a justments are
possible. (MT1 only)
When connecte with one cable an a junction box no corner a justments are possible. It is preferable
to use a 6-wire connection as this eliminates voltage rop errors in long cables cause by cable resis-
tance.

Multidrop Systems
Mo Weigh instruments can be connecte using the COM2 RS485 bus. Up to 10 systems may be con-
necte on the bus. A Mo Weigh isplay can select any one of the systems on the bus to work with.
A multi rop connection can also be use with any other Mo bus master evice such as a PLC. If a non
Mo Weigh master is use on the bus, then the Mo Weigh instruments are unable to communicate with
one another. An external Mo bus master can alternatively be connecte to an RS232 COM1 port.
An MR1 unit cannot share the bus with a non Mo Weigh master such as a PLC. A PLC coul be con-
necte using the COM3 port on the MR1.
To connect in muti rop use the RS485 connection COM2. The wiring shoul be ma e in a aisy-chain,
with one instrument connecte to the next. If a stub connection is use to a main cable as shown in the
iagram, then make sure its length limit is a here to.
Two MAT line terminators must be fitte , one at each en of the cable run.
The +D, -D an a 0V terminal must all be connecte together through the ata cable.

Setting the COM1 Modbus Address
Before a multi rop system will operate, the a resses in each of the Mo Weigh units will nee to be set
ifferently. This can be one by wiring a link or resistor to the ADS terminal where available. See the
table on the connection iagram. Alternatively the a ress setting can be change in each unit using a
isplay connecte to its COM1.
The following proce ure is use to set a units a ress.
1. Press the Q key to access the setup menu.
2. Key in the quick key co e 2512 to select the ‘COM1&2 mo bus a ress’ step.
3. Press the EDIT key. (If e iting is locke , key in the passwor 111 an press ENTER).
4. Enter the esire a ress (1, 2 or 3 etc.) an press ENTER.
5. Press an hol the BACK key to return to normal operation.
6. Repeat for each of the units which are to be use on the bus.
When the multi rop system is then connecte an powere , the isplay shoul be able to see each of
the Mo Weigh systems. This is one by pressing the SELECT key on the isplay.

Setup Diagram
The Setup contains Settings an Macros which are escribe next.
Settings
Most of the setup for a system involves setting calibration constants which for example calibrate the
loa cell input, the 4-20mA outputs an the operation of relays etc. These settings are simple numeric
values.
Macros
Macros are use to store short programs which are use to construct text strings to output to the
printer, perform arithmetic calculations an other special control functions. Macros are a collection of
program segments which can call one another as subroutines. They have structure if/then/else state-
ments an program looping constructs.
A macro is a sequence of numbers (bytes with values of 0 to 255).
Menus
All the setup parameters are containe within a menu structure which follows the setup sections.

Basic Settings
The basic settings are settings which generally must be set first an often affect other settings through
the controller. For example, they set the engineering units an measuring range for the application.
Inputs
The inputs are settings an calibration which effect the basic inputs signals. For example the loa cell
input, tacho input (where use ) an igital inputs.
Internal Signals
This section contains the main calculations for the instrument. Most signals are here, for example the
weight, zero weight, total weight etc. Much of the instruments configuration is one in this section.
Outputs
The output are settings an calibration which effect the basic output signals. For example the 4-20mA
outputs an igital outputs. These change the calibration range an select the signal to appear on the
igital outputs.
Communications & Display
This section sets the bau rates etc for the communications ports. It sets the key locks for the
MD1,MD2 Display. It also contains the Macros for the instrument.
These settings are not available in ‘B’ mo el instruments.
Information, Resets & Final Calibration
This section contains information about the unit, inclu ing its serial number, the pro uct type etc.
These settings allow all the settings & macros to be reset back to their efault values. The final calibra-
tion is also one here.
Factory Settings
The factory settings are use to calibrate the basic instrument in the factory. These are passwor pro-
tecte an are not usually require once the instrument has left the factory.

Calculations are one on a stack in RPN (reverse polish notation). When a value is entere onto the
stack with a RECALL or VALUE instruction, the other values on the stack are move up first.
An instruction like ADD or MUL opera
tes on the values in VALUE an Y an places the result in VALUE. Z
is move to Y an T is copie to Z.
The operation follows the values. e.g RECALL ‹weight› VALUE “2” MUL., this multiplies the weight by 2.
e.g. 2 + 3 x weight =
VALUE “2” VALUE “3” RECALL ‹weight› MUL ADD
S ACK RECALL or VALUE ROLL ADD, SUB, MUL, DIV, MOD
T T lost  copie
Z   
Y   
VALUE   RESULT (using VALUE & Y)
220 VALUE “number” “number” is an ASCII number (e.g. 123.4) If there is no number, then the
stack is pushe up.
221 ADD VALUE = VALUE + Y
222 SUB VALUE = VALUE + Y
223 MUL VALUE = VALUE + Y
224 DIV VALUE = VALUE + Y
225 MOD VALUE = VALUE + Y
226 SWAP_VALUE&Y VALUE an Y swappe
227 ROLL stack rolle own
230 CLEAR_VALUE VALUE is set to zero
231 CLEAR_ALL VALUE, Y, Z an T all set to 0
232 INC_ VALUE VALUE = VALUE + 1
233 DEC_ VALUE VALUE = VALUE – 1
235 CHANGE_SIGN sign of VALUE change , plus an minus
236 ABS absolute value of VALUE (e.g. ABS(-12.54) = 12.54)
237 INT integer value of VALUE (e.g. INT(12.54) = 12)
238 FIX fixe value of VALUE (e.g. INT(12.54) = 13)

operator result
AND true if both values are true
OR true if either value is true
‹con ition› is a logical expression ma e up of one or more values an operators evaluate from left
to right. e.g. ‹IN3› OR NOT ‹IN4›
‹con ition› = value [NO ] [operator] [value] [NO ] [operator]
NO reverses the sense of the value, (e.g. true becomes false).
STACK stacks the current value. The stacke value is use with an operator followe by ‹with_stack›.
DRIVE_BIT sets the bit to the value evaluate by the con ition.
e.g. IF ‹IN1› AND ‹IN2› STACK ‹IN3› AND ‹IN4› OR ‹with_stack› DRIVE_BIT ‹user bit 1›
‹event con ition› has a value of 1-150, an is true if the bit in the I/O Function table has change
since the “event macro” last ran.
‹bit› is a value from 1 to 187 from the I/O Function Table. Use Output Functions shoul not be set.
‹macro› is a macro number from 1 to 99. If macro = 101, calls subroutine number in VALUE.
The con itional an looping structures are as follows. Any sequence of instructions may be place
where INST appears.
IF ‹con ition› INST ENDIF IF_EVENT ‹event con ition› INST ENDIF
IF ‹con ition› INST ELSE INST ENDIF IF_EVENT ‹event con ition› INST ELSE INST ENDIF
IF ‹con ition› INST DRIVE_BIT ‹bit› IF_EVENT ‹event con ition› INST DRIVE_BIT ‹bit›
