3.1. Overview

Type MCS-08 is a powerful and economic state-of-the-art multi channel system for static and dynamic weighing applications plus force and torque measurements. The basic measurement module is the 1-channel type MCS-08AD A/D converter which converts the analogue low level signal from a load cell or a strain gauge sensor to a digital high-resolution and high-accuracy signal. All standard weighing functions are available on this A/D converter. For bus connections, gateways such as Profibus DP, ProfiNet, Modbus RTU and Ethernet TCP/IP are available. The gateway can communicate via the internal system bus (named N-bus) with up to 8 type MCS08AD A/D converters. For local display purposes the internal system bus can be extended with one optional type MCS-08DP Display module. The system can be extended with optional control signals located on the type MCS-08IO Digital I/O module. The gateway can communicate via the internal system bus with up to eight type MCS-08IO modules.

The type MCS-08 Multi-Channel System comprises various hardware modules which are

Figure 3.2 – MCS-08 bus system

A basic configuration of type MCS-08 Mult Channel System is shown in Figure 3.2. In this configuration the gateway module is the master of the internal N-bus and it simultaneously acts as a slave for the external bus. The gateway connects the external network with the locally installed MCS-08 hardware modules and transmits commands and responses to and from the external bus. It scans all hardware modules for their status and then transmits this status information continuously to the external bus controller.

4. INSTALLATION

Figure 4.2 – Installation on DIN-rail

PRECAUTION: Please read this manual carefully before you install the instrument. If you apply all

recommendations in this chapter you will increase the reliability and long term performance of your system.

4.1. Recommendations

4.1.1. Control Cabinet Design

Warning: Please follow the following warnings for designing the control cabinet which will increase the

reliability of your system. The control cabinet should be designed therefor the MCS-08AD modules can operate safely. The panel should be placed in a clean area, without getting direct sun light if possible, with a temperature between -10 ºC and +40 ºC, humidity not exceeding 85% non-condensing. All external cables should be installed safely to avoid mechanical damages. MCS-08 modules are very low level signal measuring instruments. To avoid electrical noise, the instruments should be separated from equipment that produces electrical noise. Preferably use a metal cabinet against radio frequency interference, to protect against electromagnetic disturbance the cabinet shall be connected to ground. Keep the load cell cable trays separated from others, if possible. If there is noise-generating equipment such as heavy load switches, motor control equipment, inductive loads etc., please be careful against the EMC interference in the cabinet. If possible protect MCS-08 modules by a Faraday cage or install them in a separate section or install them far a way from this kind of equipment. Install parallel reverse diodes to the DC inductive loads like relays, solenoids etc. to minimize voltage peaks on the DC power lines.

4.1.2. Cabling

All cables coming to the control cabinet shall be shielded. Please use separate cable trays for these low signal level cables. Distance from load cell cables, interface cables and DC power supply cables to power line cables shall be 50 cm at minimum.

4.1.3. Mechanical Installation

After designing the control panel and installing DIN rails according to the recommendation in this chapter, install the N-bus connectors on the DIN rail as shown in figure 4.1.

Figure 4.1 – N-bus connectors installed on DIN-rail

Place the modules on the DIN rail for making the connection between the N-bus and the MCS-08 modules as shown on figure 4.2. Be sure that the mechanical installation and the N-Bus connection of the modules are done properly.

Load Cell Connector

4 wire LC connection

6 wire LC connection

Warning: Connect the load cell cable shield to the reference ground or the

shield pin of the load cell connector.

Warning: Please always remember that MCS-08AD modules are very low voltage measuring instruments. Your control cabinet design and proper installation increases the reliability and the performance of the instrument. Please do not forget that the instrument must be powered off before inserting or removing any peripheral connector. All required electrical connections should be done as described below.

4.2.1. Power Supply and Grounding

The power supply voltage of the instrument shall be between 12 V DC and 28 V DC. The current consumption of the power supply will be calculated by multiplying 0.2 A and the quantity of instruments. The pin configuration of the 24 V DC power supply connector located at the bottom front of the instrument is shown below in figure

4.3.

Figure 4.3 – The pin layout of 24 V DC connector

The quality of the instrument‟s ground will determine the accuracy and the safety of your measuring system. A

proper ground connection is needed to minimize extraneous electrical noise effects on the measurement. A poor ground can result in an unsafe and unstable operation. It is important that the instrument should not share power lines with noise-generating equipment such as heavy load switching, motor control equipments, inductive loads, etc. If the condition of the power line in the plant is poor, prepare a special power line and grounding. Before interfering the instrument, turn off the power and wait at least for 30 seconds.

4.2.2. Load Cell Connection

To avoid damages, the load cell wiring should be made carefully before energizing the instrument. Load cell connection details are shown below in figure 4.4. In 4-wire installations the sense and excitation pins with the same polarity should be short circuited at the connector side. If you have a junction box in your system, use a 6 wire cable between the MCS-08AD moduler and the junction box, and short circuit these pins at junction box for better performance.

For entering the parameter settings go to the setup tab, adjust the parameter values and then write these data to the module. After writing the parameter settings to the module, calibrate the module. You can find the parameter descriptions in the next chapter.

5.5.1. Scale Parameters

In the setup menu the scale parameters can be viewed, changed or saved to the instrument. These parameter settings are:

Increased External Resolution

For service purposes this parameter enables the 10 times higher resolution of the weight value than the defined interval in weighing and force mode. Increased resolution must be disabled for use in normal operation (Not available in Count Mode). Default setting: „Disable‟.

Digital Filter

Environmental noise like bounding forces, air flow, vibration, motor control instruments etc. may disturb the load cell signal. The selection of proper filter settings determines how quickly the system will react to the load cell signal.**Load cell signal digital filtering is done according to this parameter settings. The settings can be changed from 0 (fastest settling) to 9 (slowest settling). Default setting: „7‟.

Motion Detection

This parameter defines the motion detection window which determines a stable weighing. If motion detection is not required, this parameter can be disabled. The available motion detection window values are:

Weighing and Force Mode:

Count Mode:

Power On Zero

This parameter enables automatic zeroing after powering on the instrument. The automatic zeroing is only done if the total zero drift from the calibrated zero signal is in the defined zeroing window. This zeroing window will be defined in the percentage of the scale capacity.

To avoid unwanted zeroing at power on this parameter should be disabled or carefully set up in applications like silo weighing, tank weighing and automatic weighing applications. If the weight is not within the power on zeroing range, the instrument is powered on without zeroing (Not available in Count Mode).

Zeroing Range

Zeroing of the scale is performed if the difference between load cell signal value and unloaded load cell signal value at the calibration is in the selected percentage of the scale capacity. Zeroing can be done by zeroing command when the scale is stable. Zeroing can be done by zeroing command when the scale is stable. The available zeroing ranges in the percentage of the scale capacity are:

Calibration with Test Weight: This block allows the user to calibrate with test weights.

ECal Calibration: This block allows the user to calibrate without test weights.

Calibration Coefficients: This function allows the user to restore a calibration if the calibration

coefficients have been noted before.

Count Mode:

Filtered and normalized ADC count data will be transmitted in this mode. The calibration is performed at the PLC, if any.

AZT automatically re-adjusts the scale to zero for compensating defined small deviations around the center of zero. AZT only works within the defined zeroing range and stops working if this range is left.To avoid unwanted zeroing this parameter should be disabled or carefully set up in applications like silo weighing, tank weighing and automatic weighing applications (Not available in Count Mode). The available AZT window values are;

Tare

If this function is enabled, the weight is tared when the tare command is received. Additional conditions for taring are positive gross weight and no motion. Multi-taring is possible (Not available in Count Mode). Default setting: „Enable‟.

Save Tare at Power Off

If this function is enabled, the tare value is stored at power off and the instrument starts up in Net mode at power on (Not available in Count Mode). Default setting: „Enable‟.

5.5.2. Scale Build and Calibration

Scale build, operation mode selection and scale calibration is performed in the calibration tab of xFace as shown in figure 5.7. Please follow the procedure in the sequence as described in the following chapters.

Figure 5.7 – MCS-08AD Setup Parameters

For entering the parameter values enter the setup tab, adjust the parameter settings and then write this data to the A/D Converter. After changing parameter settings the instrument always requires a re-calibration.

Mode selection

MCS-08AD modules have three operation modes which are:

selection. The default calibration of MCS-08AD modules is Count Mode and 10 mV unipolar input signal range. If you select the Count Mode, there is no scale build and instrument calibration. Each MCS-08AD module is adjusted for high accuracy during the production. The MCS-08AD input signal ranges and their external resolutions are shown in Table 5.1.

Table 5.1 - Count Mode, Input Signal Ranges and External Resolution

Select the input signal level and polarity for high external resolution. Write your mode selection to the instrument by clicking “Write to Instrument” button. Jump to the chapter 5.6.

Scale Build

The scale capacity, the increment and the unit have to be introduced to the MCS-08AD module before you can perform a calibration in Weighing or Force mode.

The scale calibration can be performed by using test weights or by electronic calibration (eCal).

Calibration by Test Weights

This calibration method performs zero and span calibrations using test weights. For accurate calibration the test weight value should not be less than 1/10 of the scale capacity.

Please note that the scale build values should be entered before you start the calibration.

Select “Full Calibration” for performing a complete scale calibration. Click the “Start” button. Unload the scale for performing the zero calibration and click the “Yes” button. The virtual display will show the [WAIT] message

during the zero calibration. During the zero calibration the scale must be stable. Approximately 5 seconds later the span calibration window will be displayed. Load the scale and enter the loaded test weight value, then click

the “OK” button. The scale must be stable during the span calibration. Approximately 5 seconds later the new

calibration settings are saved automatically.

If any error occurs during the calibration an error message warns you. Click the “Yes” button to reload the previous values or click the “No” button to use the new settings. You can adjust the zero or the span of your scale without performing a full calibration. Additionally the “span calibration to the unloaded scale” feature is another tool of MCS-08AD modules for after-sale services.

Zero Adjustment

If your scale has a residual zero drift you may perform a zero adjustment only. Select “Zero Adjustment” and press the “Start” button. Then the zero calibration window will be displayed. Unload the scale and click the “OK”

MCS-08 Technical Manual, Rev. 1.04 December 2012 Page 19 of 52

button. The [WAIT] message appears on the virtual display during the zero adjustment. Approximately 5

Figure 5.9 – eCal Calibration

seconds later the zero adjustment will be finalized. Note: Zero adjustment is also performed over the bus interface. Refer to the data structure of the related bus interface.

Span Adjustment

If your scale has a span drift, you may perform a span adjustment only. After selecting “Span Adjustment” and pressing the “Start” button, enter the test weight value; place the test weights on the scale and press the “Yes”

button. The [WAIT] message appears on the virtual display approximately for 5 seconds while the span calibration is being performed. After finalizing the span adjustment, the instrument will save the span coefficients automatically. Note: Span adjustment is also performed over the bus interface. Refer to data structure of the related bus interface.

Span Adjustment under Load

This feature is being used to perform a span adjustment without unloading the scale. This operation is especially used for the span adjustment for non-empty tanks to make a span adjustment without emptying the tank. After selecting “Span Adjustment under Load” press the “Start” button. The temporary zeroing message appears on the monitor. This means the instrument will determine the existing load as the temporary zero. If the scale is stable press the “Yes” button. The [WAIT] message appears on the virtual display approximately for 5 seconds to determine the temporary zero. Then the span calibration window will be displayed. Load the scale and enter the loaded test weight value, then click the “OK” button. The scale must be stable in this period. Approximately 5 seconds later, the new calibration settings are saved automatically. Please refer to the chapter 5.6 A/D Converter Performance Test).

Electronic Calibration (eCal)

eCal allows to perform a calibration without using test weights. MCS-08AD modules are adjusted during production for increased eCal accuracy. The calibration will be done based on the scale capacity, the total load cell capacity, the load cell output and the estimated dead load. If the conditions are convenient for zero calibration, you may perform automatic zero adjustment instead of entering an estimated dead load.

After selecting eCal calibration enter the following values as: Total Load Cell Capacity: Enter the total load cell capacity in kg as shown in the example below.

Example: If the weighing system has 4 pcs 1000 kg load cells, then enter 4000 kg. Average Load Cell Output: Enter the load cell output in mV/V. If the weighing system has more than one load

cell, calculate the mean value of the load cells output as indicated in the certificates of the individual load cells. Example: If the load cell outputs are LC1: 2.0010, LC2: 1.9998, LC3:1.9986 and LC4:2.0002, the mean value

will be LC output = ( 2.0010 + 1.9998 + 1.9986 + 2.0002 ) ÷ 4 = 1.9999 mV/V. Estimated Dead Load: Enter the estimated dead load value of the weighing system in kg. You may perform a

zero adjustment in convenient time for an exact dead load compensation. After pressing “Save eCal Data to Converter” these data will be transferred to the instrument and eCal will be finalized.

If the scale is empty and you want to make an automatic zero adjustment instead of entering an estimated dead

load, then press the “eCal with Zero Adjustment” button for starting the zero calibration. The display will show

the [WAIT] message during the zero adjustment for approximately 5 seconds. In this period the scale must be unloaded and stable. The eCal calibration coefficients are saved automatically.

5.6. A/D Converter Performance Test

The scale performance test should be performed before you install the bus connection. The tests are linearity, repeatability and eccentricity. You can follow the test at the virtual display and/or status tab which show the measurement data, the instrument data and the software version. For convenience keys for Taring, Zeroing and Clear are located in this tab.

MCS-08 Technical Manual, Rev. 1.04 December 2012 Page 20 of 52

5.7. Digital I/O Test

Figure 5.10 – MCS-08IO Status

Input / Output Test: This block allows the user to check I/O status. The I/O test button is used to test outputs as seen in this figure.

Figure 5.11 – Example

The active MCS-08IO modules are shown with their own N-Bus address block. You can follow the input and the output status and you can switch the outputs. The I/O test property is very useful for checking the output states.

Warning: Please be careful to avoid damaging your process during the output test.

5.8. N-Bus Addressing via Setup Switch

MCS-08 systems which are energized for the first time require the N-bus addressing for each A/D Converter module and each Digital I/O module. One way is the addressing by the xFace which is described above. Another way is the addressing (up to address 7) via the setup switch.

Step by step manual procedure:

1. Unplug all communication cables from the Gateway Module (RS232 and BUS plug; See GREEN).

2. First energize the modules installed on the N-Bus.

3. Press the setup switch of the gateway module for 5 seconds. (The switch is behind the hole in the front; see

YELLOW). The three LEDs of the gateway module (RED) will flash 4 times and then indicate an N-Bus

address number. You can change the address number by pressing the setup switch (YELLOW) slowly. While changing the address in the Gateway module, the LEDs in the other modules (PINK) will change sometimes.

MCS-08 Technical Manual, Rev. 1.04 December 2012 Page 21 of 52

4. Now change the address number on the Gateway Module by pressing the gateway switch (YELLOW) until it

reached an address you want to use for an MCS08AD or MCS08IO module.

5. To assign the selected address number to an A/D Converter or Digital I/O module press the setup switch on the selected module (BLUE).

Please note: The MCS08 allows up to 8 A/D and 8 I/O in one system. A/Ds and I/Os use the same address range (0 to 7). In consequence the same address can be assigned to one A/D Converter AND one Digital I/O Module.

6. After assigning all modules to a defined address, press and hold the gateways switch for 5 seconds. The system will close the addressing mode and change to normal mode

Note: Do not de-energise MCS-08 while the system is in the addressing mode. If a power failure has

happened, restart the system and repeat the whole addressing.

LED and Setup Switch Descriptions in the N-Bus Addressing Mode:

Table 5.2 – N-bus addressing via setup switch

5.9. Back up Settings and Calibration Data

The parameter settings and the calibration coefficients can be saved to a backup file after reading these data from the MCS-08 modules. This backup file can be re-written to MCS-08 modules after opening it by xFace. The backup feature gives a service advantage to MCS-08 systems. We propose to burn these files to CD / DVD and save this backup CD / DVD in the control cabinet additionally to a backup file on your PC.

Important note: The previous parameter settings and calibration coefficients in a MCS-08 module will get lost after loading a backup to this module.

5.10. Modbus Data Structure (for MCS-08MB + MCS-08EN only)

EXPLANATION

Attention: For hardware connection details, please refer to the related hardware descriptions in chapter 9

(respective chapter 12 for MCS-08EN gateway). The Modbus slave address is defined in the Modbus RTU Setup in chapter 9.4. Function code „0x03‟ and function code „0x10‟ are supported. In the two word registers the data is stored to the registers in big-endian format. The least significant word is stored to the highest register address; and the most significant word is stored to the lowest register address. Write operations can only be done to the allowed registers. These registers are indicated as W or W/R in the tables. Do not try to write „only read‟ registers indicated as R. The Modbus data structure tables identify the N-bus address of MCS-08AD and MCS-08IO modules as [X]. Please find Modbus information on the web site of http://www.modbus.org
