1 Introduction

1 Introduction

1.1Instrument description

The 915 KF Ti-Touch is a compact titration system for volumetric Karl Fischer titration. This newly designed titrator combines in a single device the touch-sensitive color monitor for convenient and efficient operation, the titration unit, the magnetic stirrer and the integrated membrane pump for adding and aspirating solvents. The upper side of the housing offers space for the titrant and the titration cell. The titrator is standard-equip- ped for operation with an external dosing drive of the 800 Dosino type with a dosing unit. You can however also use a 805 Dosimat with an exchange unit. Thanks to its compact construction, you can use the

915 KF Ti-Touch in a small space as a stand-alone titrator.

You manage titrants, sensors, methods, etc. conveniently in the internal memory of the 915 KF Ti-Touch. You can also save your files externally through the USB connector, e.g. on a USB flash drive. On this storage medium you can not only store your methods and determinations, but also create a backup together with all of the data and settings of your system.

The integrated Ethernet connection is available to you should you wish to connect your 915 KF Ti-Touch to a network. The network connection offers you the following advantages:

Saving data to a PC within the network

Printing reports on a network printer

Sending displayed messages as e-mails

4.3 Connecting MSB devices

4.3Connecting MSB devices

In order to connect MSB devices, e.g. dosing device or Remote-Box, the Ti-Touch has two connectors at what is referred to as the Metrohm Serial Bus (MSB). Various peripheral devices can be connected in sequence (Daisy Chain) at a single MSB connector (8-pin Mini DIN socket) and be controlled simultaneously by the Ti-Touch. In addition to the connection cable, stirrers and the Remote Box are each equipped with their own MSB socket for this purpose.

The following figure provides an overview of the devices that can be connected to an MSB socket, along with a number of different cabling variations.

4.3.2Connecting an additional stirrer or titration stand

In addition to the built-in magnetic stirrer, you can also use the magnetic stirrers 801 Stirrer, 803 Ti Stand or the 804 Ti Stand with the propeller stirrer 802 Stirrer.

Proceed as follows:

1 Switch off the Ti-Touch.

2Connect the connection cable of the magnetic stirrer or of the titration stand to MSB 2 (2-5) on the rear of the Ti-Touch.

3Connect the propeller stirrer, if desired, to the stirrer connector of the titration stand.

4Switch on the Ti-Touch.

4.3.3Connecting a Remote Box

Instruments that are controlled via remote lines and/or which send control signals via remote lines can be connected using the 6.2148.010 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 Switch off the Ti-Touch.

2Connect the Remote Box connection cable to an MSB connector (2-5) on the rear side of the Ti-Touch.

3 Switch on the Ti-Touch.

You can connect an 885 Compact Oven SC. The Remote Box also has an MSB socket at which a further MSB device, e.g. a dosing device, can be connected.

You will find precise information concerning the pin assignment of the interface on the Remote Box in Appendix (see Chapter 31.5, page 341).

4.4Connecting USB devices

4.4.1General

The 915 KF Ti-Touch has a USB connector (Type A socket) for peripheral devices with USB interface and for USB Sample Processors. If you wish to connect more than one device to the USB, you can also use an additional commercially available USB hub.

NOTE

We recommend that the Ti-Touch be switched off while you set up or disconnect connections between the devices.

4.4.2Connecting a USB hub

Use a USB hub with its own power supply.

Connect the USB hub as follows:

1With the help of the 6.2151.030 cable (length 0.6 m) or the 6.2151.020 cable (length 1.8 m), connect the USB connector of the Ti-Touch (Type A) with the USB connector of the hub (Type B, see manual for the USB hub).

The USB hub is recognized automatically.
