Operation

2.4.4. Calibration

Calibration is the process of adjusting the display of the transmitter so that when the scale is empty, the display shows zero gross weight. With a specific amount of weight on the scale, it also shows an accurate weight value.

The ACT350 transmitter calibration menu enables entry of a GEO Codes adjustment value, selection of linearity adjustment (none [default], three, four or five point), traditional zero calibration and three different types of span calibration:

 Traditional span calibration – This uses test weights.  Step adjust calibration - Using a build-up or substitution method of

calibration, this method is used for large vessels where only a portion of the required test weights can be placed on the scale.

 CalFree calibration – Once certain load cell criteria have been entered

manually, the transmitter will automatically calculate the span; no test weights are required.

Page 19

30303895 | 001 | 09/2018 METTLER TOLEDO ACT350 Transmitter User's Guide 15

Operation

2.4.4.1. Setting Calibration

Access to the Calibration menu using the device's front panel is accomplished by pressing the ENTER key when the icon is displayed on the device. The Calibration menu also can be accessed using the PC-based Setup+

Configuration Tool.

Figure 2-6: Calibration Menu – Overview

2.4.4.2. Setting Geo Code

The Geo code, which sets the appropriate adjustment value for the current geographical location, is selected here. Geo codes are numbered 0–31. See Figure 2-6 for more information on the Geo code setting using the transmitter’s front panel buttons, and refer to Appendix E, Geo Codes to find the appropriate Geo Code for the installation location.

Page 20

30303895 | 001 | 09/2018 METTLER TOLEDO ACT350 Transmitter User's Guide 16

Operation

2.4.4.3. Setting Linearity

To set the Linearity Adjustment value, see Figure 2-6: Calibration Menu – Overview Figure 2-6. Choose the number of linearity points from the selection box. Options are None [default], 3 point, 4 point, 5 point.

Points are distributed as follows:

None

Linearity is disabled

Zero, midpoint and highpoint

Zero, lowpoint, midpoint and highpoint

Zero, lowpoint, midpoint, midhighpoint, highpoint

2.4.4.4. Zero Calibration and Under Zero Blanking

Scale zero is set simply by emptying the scale and running the “Set Zero”

calibration routine, as shown in Figure 2-7.

Figure 2-7: Zero Calibration

Page 21

30303895 | 001 | 09/2018 METTLER TOLEDO ACT350 Transmitter User's Guide 17

Operation

If the transmitter detects scale motion during the calibration process, it will retry the start of calibration several times and then proceed, displaying a motion indication. In this case, when calibration is complete, the transmitter will present two options – accept or reject the value.

Figure 2-8: Zero Calibration with Motion

Blanking of the display is used to indicate an under-zero condition when the weight on the scale falls below the current zero reference. Set the under zero blanking for the number of divisions (d) that the transmitter is permitted to go under zero before blanking.

NOTICE

A setting value of 0-98 blanks the display at the specified number of divisions below gross zero. A value of 99 disables blanking under zero and the transmitter will display a weight as far under as possible.

Page 22

30303895 | 001 | 09/2018 METTLER TOLEDO ACT350 Transmitter User's Guide 18

Operation

2.4.4.5. Span Calibration

The scale’s span calibration can be determined either with or without a linearity

adjustment. With linearity disabled, a single reference point is used to calibrate the scale. This is the normal method of span calibration. In Figure 2-9, the transmitter is configured with three-point linearity – low, mid and high.

The low point is set during zero calibration, and the mid and high points are set during this procedure.

Figure 2-9: Span Calibration

If linearity is enabled, additional mid-range weight reference points are added to the adjustment procedure. Linearity can be enabled or disabled in the Calibration branch of the device menu. Refer to ACT350 Device Main Menu section for the method used to modify numerical values.

2.4.4.6. Step Adjust

Step adjustment is an iterative process in which a build-up or material substitution method of calibration is used to calibrate the span. Each step calibrates a portion of the full span.

This method is typically used with large vessels where only a portion of the required calibration test weights can be placed on the scale at one time. Figure 2-10 shows the logic of the procedure using a simple, two-step example. When sufficient steps have been calibrated, pressing the LEFT button returns the view to the calibration menu.

Page 23

30303895 | 001 | 09/2018 METTLER TOLEDO ACT350 Transmitter User's Guide 19

Operation

First, a test load is defined by entering its weight.

Confirm the value entry by pressing ENTER.

The ACT350 prompts for the addition of the test load.

Press ENTER to start the first step,

The ACT350 indicates its progress.

Once the first step is calibrated, the ACT350 sets a temporary zero point, and prompts for the removal of the test load. A live weight display indicates that the scale has been cleared.

Press ENTER to confirm the scale is empty.

The ACT350 will prompt to add the test load again.

The live weight indicates that the test load is on the scale.

Press ENTER to start the second step.

The ACT350 indicates its progress.

Press LEFT to complete calibration and exit the procedure.

The ACT350 indicates that the calibration has succeeded.

Press either LEFT or ENTER to return to the calibration menu.

Figure 2-10: Step Adjustment

30303895 | 001 | 09/2018 METTLER TOLEDO ACT350 Transmitter User's Guide 20

Operation

2.4.4.7. CalFree™

CalFree allows the scale to be calibrated without the use of test weights. The total load cell capacity, unit and output in mV/V must be entered. The system then calculates correct calibration for the scale. Figure 2-11 provides a visual representation of the CalFree calibration procedure.

Notes on Load Cell Capacity and Rated Cell Output

 For load cell capacity, enter the sum of all load cell capacities. For

example, for three 50t load cells, enter 150,000 kg.

 For systems with passive dummy load cells, enter the value as if all legs

have live load cells. For example, for a system with two 50t live load cells and two passive supports, enter 200,000.

 For Rated Cell Output, enter the sensitivity of each live load cell in mV/V –

for example, 2.0000. For multiple load cells, enter the average sensitivity of all cells.

The ACT350 transmitter allows calibration of the scale without using test weights. This is based on manual entry of capacity and performance data from the load cell or load cell platform. This method of calibration can be used for initial check-out and testing of systems or when a large structure is used as the weighing vessel and it is not possible to apply test weights to the structure. METTLER TOLEDO highly recommends that test weights be used whenever possible, as this provides the most accurate method of calibration.

The Rated Cell Output and Cell Capacity values cannot be zero, and are limited to 7 digits.

NOTICE

Scale calibration using CalFree™ will not be accurate when using zener diode barriers (such

as Mettler Toledo ISB05 and ISB05x) between the transmitter and the scale. Do not use

CalFree™ when barriers are installed.

2.4.8. Reset Configuration and Master Reset

2.4.8.1. Reset Configuration

To reset all configured items except calibration data:

1. Remove power from the transmitter.

2. Locate the DIP switches, accessible from the underside of the housing.

3. Set both DIP switches, 1 and 2, to ON (up, in Figure 2-13), and restore

power to the transmitter.

Figure 2-13: DIP Switches

4. Set both DIP switches to OFF.

Operation

2.4.8.2. Master Reset

A master reset restores all settings to their factory default values:

1. Remove power from the transmitter.

2. Set switch 2 to its ON position and restore power to the transmitter.

The ACT350 will prompt for confirmation.

Figure 2-14: Master Reset Confirmation

3. Press ENTER on the front panel to perform the master reset.

4. Set Switch 2 to OFF.

2.2. ACT350 Basic Operation Functions

2.2.1. Zero

The Zero function is used to set or reset the initial zero reference point of the transmitter. There are two types of zero setting modes:

2.2.1.1. Green ENTER Button

The zero function can be accomplished by a short press of the green ENTER

scale function key. The Zero range selections include Disabled, 2% [default] or 20% plus or minus from the calibrated zero point. A change to the default setting is done via the PC-based Setup+ Configuration Tool. If the current scale weight is outside the zero range when a pushbutton zero is commanded, the transmitter will display a message:

Figure 2-15: ENTER button Zero Failure Message

Remote initiation of the semi-automatic Zero command is possible via a command initiated by the PLC interface.

Page 28

30303895 | 001 | 09/2018 METTLER TOLEDO ACT350 Transmitter User's Guide 24

Operation

2.2.1.2. Power Up

The Power Up mode setting determines if at power up, the transmitter will restart with the most recent zero reference point it had before power down or if it will reset to the calibrated zero reference.

The selections include Reset [default] and Restart.

2.2.1.2.1. Reset

With the setting on Reset, the last zero calibration value will be used as the zero reference point. The Power Up Zero capture range selections include Disabled [default], 2% or 10% plus or minus. If the range setting is enabled, the Power Up Zero is applied only when the weight reading on the scale is within the selected range around the originally calibrated zero reference. For example, if the range setting for Power Up Zero is set at +/- 2%, Power Up Zero will only occur when the weight reading on the scale is within +/- 2% of scale capacity above the original calibrated zero reference. If the weight on the scale is outside of the zero range, the display will indicate EEE until the weight is adjusted to within this range and zero is captured.

2.2.1.2.2. Restart

A setting of Restart enables the transmitter to reuse the most recent zero reference weight after a power cycle so it returns to the same, previouslydisplayed gross weight value. The Power Up Zero setting is configured using the PC-based Setup+ Configuration Tool.

2.2.2. Tare

The tare value is subtracted from the gross weight measurement, providing the computation of the net weight (material without the container). The tare function can also be used to track the net amount of material being added to or removed from a vessel or container. In the second case, the weight of the material inside is included with the tare weight of the container and the display reflects the net amount being added to or removed from the vessel. Tare is captured by PLC command. Tare is cleared by PLC command.

Operation

2.2.3. Filter

The Filter section offers three settings:

Limit Frequency

Selections from 1 to 20 in this drop-down box set the cut-off frequency, in Hertz, above which the filter actively attenuates the signal.

Weighing Mode

Sets the type of weighing, Normal, Dynamic, Trigger Weigh for which the ACT350 is being used in the current application.

Environment

Sets the type of environment in which the ACT350 is working, depending on how stable the scale is likely to be.

2.2.3.1. Triger Weigh

Triggered weight mode is to determine the weight value during the dynamic weighing process of the weighing object, and the key technical indexes are the weighing accuracy and throughput rate. More information are available in Appendix A

Fieldbus Communication

4 Fieldbus Communication

4.1. Overview

The Standard Automation Interface (SAI) is a protocol designed to exchange data between METTLER TOLEDO devices and third-party automation systems. This interface provides the following:

• A common data layout for load cells, terminals and other devices

regardless of the physical interface or automation network used.

• A single protocol for the convenience of automation integrators,

control system programmers and our automation customers.

• A flexible protocol for diverse devices.

Communication Modes

The protocol has two primary modes of operation.

• cyclic data • acyclic data

4.1.1. Cyclic data

Cyclic data is broken up into sections of data. Each section represents a block. Each block of data contains four words of 16 bits each.

The data within these words can express numeric values, individual bits which represent state or command depending on the type of block specified.

Two fixed formats divided into blocks (1 block, 2 blocks) are available for SAI devices depending on the product. The default format for weigh modules is the two block format with eight words in and eight words out. The number of input words (data sent from the device to the process controller) and output words (data sent from the process controller to the device) always match. This limits the number of configurations to a reasonable amount.

There are two types of cyclic blocks supported on the SAI device:

• Measuring block (IEEE 754 floating point data)

– Used for numeric values

– Decimal point and sign included and do not require special data handling

• Status block

– Used for numeric values

– Status block data grouped together in 16 bit words.

NOTICE

Acyclic data is also referred to as asynchronous data or explicit messaging.

Page 43

30303895 | 001 | 09/2018 METTLER TOLEDO ACT350 Transmitter User's Guide 39

Fieldbus Communication

4.1.2. Acyclic data

With acyclic messages, the variable can be accessed directly through a unique name or number defined by the control system's acyclic message block.

Refer to the applicable SAI Reference Manual available at www.mt.com/ind-act350-downloads for detailed information

NOTICE

Acyclic data is also referred to as asynchronous data or explicit messaging.

Troubleshooting

5 Troubleshooting PLC

Connectivity

If the ACT350 does not communicate with PLC, do the following:

 Power cycle the ACT350 to reestablish communications.  A solid green NW LED on the front panel implies that the ACT350 is on

the network. A flashing NW LED indicates that the ACT350 is not on the fieldbus network.

 Check LED status of the connection socket. The top LED should be

solid green. If the top LED is not solid green, this implies that no hardware connection is seen by the device -check cabling and connector insertions. The bottom LED will blink amber if data is being transferred. If the top LED is solid green, but the bottom LED is not blinking, this implies a configuration issue - either in the ACT350 or the PLC.

 Confirm that the ACT350 can respond to a ping on the network. If it

doesn’t, check the wiring and network connections.

 Diagnose and correct specific network error conditions such as IP

Address conflicts.

 Confirm that the ACT350 settings for address, format and byte order

match those in the PLC and that each ACT350 has a unique address.

 Check the Electronic Keying from in the PLC program. Confirm that the

firmware revision of the Ethernet/IP module in the ACT350 is greater than or equal to the firmware revision specified in the ACT350’s communication module in the PLC. Change the firmware revision being looked for in the PLC’s communication module if necessary.

 Contact METTLER TOLEDO for replacement of the ACT350 transmitter.  Visit the METTLER TOLEDO web page at www.mt.com/ind-act350-

downloads to check actual Troubleshooting information.

GEO CODES

7 GEO Codes

The GEO code feature provided in the ACT350 transmitter permits calibration readjustment due to changes in elevation or latitude without reapplying test weights. This adjustment assumes a previously accurate calibration was completed with the GEO code set properly for that original location, and that the GEO code for the new location can be accurately determined. The procedure for using this feature is as follows.

7.1. Original Site Calibration

1. Use the GEO code chart (Table 7-1) on the following pages to determine

the GEO code for the current altitude and location at which the scale will be calibrated.

2. Enter that GEO value into the GEO code parameter in setup at Scale >

Calibration.

3. Immediately after entering the GEO code, perform a zero and span

adjustment using accurate test weights.

4. Exit the setup menu tree.

5. The scale can now be used in its new location.

7.2. New Site GEO Code Adjustment

When a terminal is to be reinstalled at a different geographic location, gravitational and altitude changes can be accounted for by following these steps. Note that this procedure is not necessary if an on-site recalibration is performed.

1. Use the GEO code chart (Table 7-1) on the following pages to determine the

GEO code for the new altitude and location at which the scale will be used.

2. Enter that GEO value into the GEO code parameter in Setup at Scale >

Calibration.

3. Immediately after entering the GEO code, exit the setup menu tree. DO NOT

perform a normal calibration.

The calibration has now been adjusted for the differences in gravity from the original site of calibration to the new site of use.

Using the GEO code value for calibration adjustment is not as accurate as

re-applying certified test weights and re-calibrating the scale in a new location.

Setup+ Configuration

8 Appendix A -Trigger Weight

Triggered weight application is to determine the weight value during the dynamic weighing process of the weighing object, and the key technical indexes are the weighing accuracy and throughput rate.

This appendix describes:

 how to use the triggered weight application on ACT350DIO,  how to install,  how to calibrate,  how to configure the parameters of application  how to get the weight value by PLC.

8.1. Electrical Installation

Regarding the installation, please make sure the following physical connections:

1) Power Supply: connect to the DC power, and the range is from 10V DC – 30V DC. Typically 24V DC.

2) Load cell interface: connect to the analog load cell with 4 or 6 wires, and pay more attention about the ESD protection (Ferrite and silicone sleeve), and the sensitivity of the load cell should be 1mv/v or 2mv/v.

3) Digital input and output: please connect signal from light barrier to the digital input of the ACT350, and this is required by triggered weight application.

4) PLC interface: use the shield cable to keep the communication quality.

NOTICE

The Trigger Weight Mode is available only on ACT350DIO version, as a specific weighing function. There are no dedicated special approvals and certificates available for ACT350DIO and related with this mode. Only static weighing approvals are available.

8.2. Trigger Weight Typical example.

Trigger weight application is to determine the weight value during the dynamic weighing process of weighing object, and the key technical indexes are the weighing accuracy and throughput rate.

Figure 8-1: Trigger Weight Mode example

Please see the Figure 8-1 as the typical triggered weight system:

 Infeed conveyor: moving the weighing object into the weighing conveyor;  Weighing conveyor: detecting the weighing object coming by the light barrier

(①), and start the weighing process when the whole weighing object is on the scale, and determine the weight of the weighing object when it is leaving (②);

 Outfeed conveyor: moving the weighing object into the manufacture.

In order to get the better weighing accuracy, the time of whole weighing object should be as longer as possible, and also the system disturbance should be as smaller as possible, but should also consider the system throughput rate. The main parameters of the system are: Scale belt speed (m/s): Scale platform length (m) Object distance (m): to keep only one weighing object on the weighing conveyor, otherwise the weighing accuracy will be very poor; Object length (m):

8.3. Calibration

The calibration can be performed using a device main menu or Setup+. Before calibration, please configure the scale capacity, scale incremented size.

NOTICE

Sensor signal and light barrier signal must be connected to ACT350 correctly; otherwise it is impossible to run the triggered weight mode.

Bit #

Soft Alarm

Description

Rate of change error

Product, application or customer defines a weight / time scenario as a method of assurance that the scale is detecting weight. A typical application would be a filling system where either the material is not available for filling or a feeding system is not transporting material to the scale (slow fill timeout)

Communication error

relates to a device that is connected to a sensor or terminal and the necessary communication is not functioning according to specification

Over / under voltage(s)

relates to a device that is supports dynamic measurement of system power for example POWERCELL CAN network voltages

Weight drift

relates typically to a strain gage sensor that either has a broken bridge or is damaged by water or lightning. The drift weigh vs. time is outside of acceptable tolerances.

Breach

the sensors enclosure has been compromised and therefore vulnerable to outside influences such as moisture / water – in most cases a failure will occur if the breach is not corrected or the

sensor replaced

Calibration expired

Customer / technician determines the maximum number of

transactions, or a time limit to occur before a preventative service or recalibration – the alarm will toggle on N+1 weighing transactions
