3. INTRODUCTION
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
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.

4.2. Electrical Connections
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.

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.
