16 3.1 Setting up the instrument 3 Installation 3.1 Setting up the instrument Packaging The instrument is supplied in highly protective special packaging together with the separately packed accessories. Keep this packaging, as only this ensures safe transportation of the instrument Checks Immediately after receipt, check whether the shipment has arrived complete and without damage by comparing it with the delivery note Location The instrument has been developed for operation indoors and may not be used in explosive environments. Place the instrument in a location of the laboratory which is suitable for operation, free of vibrations, protected from corrosive atmosphere, and contamination by chemicals. The instrument should be protected against excessive temperature fluctuations and direct sunlight. 3.2 Connecting a controller Operation Two different versions are available for operating the 856 Conductivity Module: A Touch Control with touch-sensitive screen. It forms a "stand-alone instrument" together with the 856 Conductivity Module. A computer enables handling of the 856 Conductivity Module with the aid of a PC software, e.g. tiamo. Caution Take care to ensure that the mains cable is pulled out of the mains connection socket before either setting up or disconnecting connections between the instruments Conductivity Module

17 3 Installation Connecting a Touch Control Connect the Touch Control as follows: 1 Insert the plug of the Touch Control connection cable into the controller socket. Figure 4 Connecting a Touch Control Note The plug is protected against accidental disconnection of the cable by means of a pull-out protection feature. If you wish to pull out the plug, you will first need to pull back the outer plug sleeve marked with arrows. 2 Connect all peripheral devices. Connect MSB devices (see Chapter 3.3, page 12) Connect USB devices (see Chapter 3.4, page 16) 3 Connect the 856 Conductivity Module to the mains. 4 Switch on the Touch Control The Touch Control power supply is supplied through the 856 Conductivity Module. System tests are run automatically on both the 856 Conductivity Module and the Touch Control at the time of switch-on. The On LED on the front side of the 856 Conductivity Module lights up when the system test has been completed and the instrument is ready for operation. 856 Conductivity Module 9

18 3.2 Connecting a controller Caution Connecting a computer The Touch Control must be shut down properly by switching off with the On/Off switch on the rear of the instrument before the current supply is interrupted. If this is not done, then there is a danger of data loss. Because of the fact that the power supply for the Touch Control is provided through the 856 Conductivity Module, you must never separate the 856 Conductivity Module from the mains (e.g. by switching off with a connector strip) before you have switched off the Touch Control. If you would prefer not to position the Touch Control directly next to the 856 Conductivity Module, then you can lengthen the connection between 856 Conductivity Module and Touch Control using the cable. The maximum connection length permitted is 5 m. The 856 Conductivity Module requires a USB connection to a computer in order to be able to be controlled by PC software. When the controller cable is used, the 856 Conductivity Module can be connected directly, either to a USB socket on a computer, to a connected USB hub or to a different Metrohm control instrument. Cable connection and driver installation A driver installation is required in order to ensure that the 856 Conductivity Module is recognized by the PC software. To accomplish this, you must comply with the procedures specified. The following steps are necessary: 1 Install software Insert the PC software installation CD and carry out the installation program directions. Exit the program if you have started it after the installation. 2 Establish cable connections Connect all peripheral devices to the instrument. Connect MSB devices (see Chapter 3.3, page 12) Connect USB devices (see Chapter 3.4, page 16) Connect the 856 Conductivity Module to the mains supply if you have not already done this. The On LED on the front side is not yet illuminated! Connect the 856 Conductivity Module to the USB connector (type A) on the computer (see manual for the computer). The cable is used for this purpose Conductivity Module

If you wish to pull out the plug, you will first need to pull back the outer plug sleeve marked with arrows. Registering and configuring in the PC software The 856 Conductivity Module must be registered in the configuration of your PC software. Once that has been done, you can then configure it according to your requirements. Proceed as follows: 1 Set up the Conductivity Module Start up PC software. The 856 Conductivity Module is recognized automatically. The configuration dialog is displayed. Make configuration settings for the 856 Conductivity Module and its connectors. 856 Conductivity Module 11

20 3.3 Connecting MSB devices More detailed information concerning the configuration can be found in the documentation for the respective PC software. 3.3 Connecting MSB devices In order to connect MSB devices, e.g. stirrers or dosing devices, Metrohm instruments are equipped with up a maximum of four connectors at what is referred to as the Metrohm Serial Bus (MSB). Various kinds of peripheral devices can be connected in sequence (in series, as a "daisy chain") at a single MSB connector (8-pin mini-din socket) and controlled simultaneously by the respective control instrument. In addition to the connection cable, stirrers and the remote box are each equipped with their own MSB socket for this purpose. The following illustration provides an overview of the devices that can be connected to an MSB socket, along with a number of different cabling variations. Stirrer / Ti Stand MSB Remote Box Relay Box Ti Stand / Stirrer Dosino / Dosimat Dosimat Dosino Figure 6 MSB connectors Dosimat / Dosino The question of which peripheral devices are supported depends on the control instrument Conductivity Module

21 3 Installation Note When connecting MSB devices together, the following must be observed: Only one device of the same type can be used at a single MSB connector at one time. Type 700 Dosino and 685 Dosimat dosing devices cannot be switched together with other MSB instruments on a shared connector. These dosing devices must be connected directly to the control device. Caution Connecting dosing devices Exit the control software before you plug MSB instruments in. The control instrument recognizes when it is switched on which instrument is connected at which MSB connector. The operating unit or the control software enters the connected MSB devices into the system configuration (Device manager). MSB connections can be extended with the cable. The length of the connection must not exceed a maximum of 5 m. Up to four dosing devices can be connected to the instrument (MSB 1 to MSB 4). The following dosing types are supported: 800 Dosino 700 Dosino 805 Dosimat 685 Dosimat Proceed as follows: 1 Connect a dosing device Exit the control software. Connect the connection cable to one of the sockets marked with MSB 1 to MSB 4 on the rear side of the 856 Conductivity Module. Start the control software. 856 Conductivity Module 13

22 3.3 Connecting MSB devices Figure 7 Connecting a dosing device If you connect a stirrer and a dosing device of the type 800 Dosino (or 805 Dosimat), then it is recommended that the stirrer should be connected to MSB 1 and the dosing device to the MSB connector of the stirrer. These correspond to the default settings in the method templates Connecting a stirrer or titration stand You can use a magnetic stirrer 801 Stirrer or 803 Ti Stand (stirring "from below") or the 804 Ti Stand with a rod stirrer 802 Stirrer (stirring "from above"). Connect a stirrer or a titration stand as follows: 1 Connect a stirrer or titration stand Exit the control software. Connect the connection cable of the magnetic stirrer or of the titration stand to one of the sockets marked with MSB 1 to MSB 4 on the rear side of the 856 Conductivity Module. If desired, connect the rod stirrer to the stirrer socket (with stirrer symbol) of the titration stand. Start the control software Conductivity Module

23 3 Installation Figure 8 Connecting an MSB stirrer Figure 9 Titration stand with rod stirrer Connecting a remote box Instruments that are controlled via remote lines and/or which send control signals via remote lines can be connected using the remote box. In addition to Metrohm, other instrument manufacturers also use similar connectors that make it possible to connect different instruments together. These interfaces are also frequently given the designations "TTL Logic", "I/O Control" or "Relay Control" and generally have a signal level of 5 volts. Control signals are understood to be electrical line statuses or brief (> 200 ms) electrical pulses which display the operational state of an instrument or which trigger or report an event. Sequences on a variety of instruments can thus be coordinated in a single complex automation system. No exchange of data is possible, however. Proceed as follows: 1 Connect a remote box Exit the control software. Connect the connection cable of the remote box to one of the sockets marked with MSB 1 to MSB 4 on the rear side of the 856 Conductivity Module. 856 Conductivity Module 15

24 3.4 Connecting USB devices Start the control software. Figure 10 Connecting a remote box You can, for example, connect an 849 Level Control Box (fill level monitor in a waste canister) or a 731 Relay Box (switch box for 230/110 volt alternating current sockets and low-voltage direct current outlets). The remote box also has an MSB socket at which a further MSB instrument, e.g. a dosing device or a stirrer, can be connected. You will find precise information concerning the pin allocation of the interface on the remote box in Appendix (see Chapter 6.1, page 27). 3.4 Connecting USB devices General The 856 Conductivity Module has two USB connectors (type A sockets) for connecting peripheral devices with USB interfaces. It functions as a USB hub (distributor) no matter how it is operated. If you wish to connect more than two devices to the USB, you can also use an additional commercially available USB hub (see Chapter 3.4.6, page 21). Caution If you operate the 856 Conductivity Module with the aid of the Touch Control, take care to ensure that the Touch Control is switched off when you set up or disconnect connections between the various instruments. If you use a PC software to control the 856 Conductivity Module, you should exit the program before you set up or disconnect the USB connections Connecting a printer Printers that are connected to the 856 Conductivity Module with Touch Control must meet the following requirements: Printer languages: HP-PCL, Canon BJL Commands or Epson ESC P/2 Printer resolution: 300 dots/inch or 360 dots/inch (Epson) Paper format: A4 or Letter, single-sheet feed.
