822 Titration Curve Simulator, Instructions for Use III
1 Introduction

1 Introduction

These Instructions for Use give you a overview of the applications and the functionality of the 822 Titration Curve Simulator.
First, the device as such and the simulation of the titration curves are explained. The description of the additional curves, the explanation of the LEDs and the technical data are summarized in the appendix.

1.1 Instrument description

The 822 Titration Curve Simulator is a diagnostic tool that allows Metrohm service technicians to check titrators. With this simulator a possible malfunction of the titration or dosing device or even the elec­trode can be identified quickly and easily. This is done by connecting the 822 Titration Curve Simulator instead of an electrode. During the test it simulates a titration, i.e. the user gets a titration curve without us­ing electrodes or chemicals.

1.3 Functional principle

The 822 Titration Curve Simulator uses the dosing pulses of the titrator to output, as the volume increases, an analog signal corresponding to the titration curve selected. These values are evaluated again by the ti­trator and the equivalence points found are displayed. The data sets of the titration curves are stored digitally in the Curve Simulator. This al­lows to achieve an excellent reproducibility of the equivalence points.

2 Connection

2 Connection

Titrators with internal dosing drive do not need an additional dosing de­vice. Titrators without internal dosing drive (e. g. 809/836 Titrando, 726/796 Titroprocessor) need a connected dosing device (685/805 Dosimat or 700/800 Dosino). The Curve Simulator is con­nected between titrator and dosing device.
A detailed list of the connecting combinations can be found in the draw­ings given below.
Note! The 822 Titration Curve Simulator does not replace a dosing device!
The communication protocol 1 has to be adjusted depending on the type of the external dosing device connected. The setting is not impor­tant for internal dosing drives.

2.1 Connection to the MSB interface

2.1.1 Connection to Titrandos with internal dosing drive
Connect the 822 Titration Curve Simulator with the connector cable
4 to the MSB 2 connection of the Titrando.
Connect the measuring input of the Titrando with the Analog Output
7 of the 822 Titration Curve Simulator using the 6.2116.020 cable.
Adjust the communication protocol 1 to 25 bit.
Signals for the internal dosing drive can only be read at MSB 2. There­fore you have to activate the checkbox Send dosing signals to MSB 2 under System/Diagnosis/822 Curve Simulator. This setting will only be deactivated when restarting the PC Control software or switching off and on the Touch Control.
822 Titration Curve Simulator, Instructions for Use 3
2.1 Connection to the MSB interface
Note! No dosing device may be connected to the 822 Titration Curve Simulator in this case.
2.1.2 Connection to Titrandos by using an external dosing device
Connect the 822 Titration Curve Simulator with the connector cable
4 to any of the four MSB connections of the Titrando.
Connect the dosing device to the Dosing device connection 6 of the
822 Titration Curve Simulator.
Connect the Analog Output 7 with the measuring input of the Ti-
trando using the 6.2116.020 cable.
The communication protocol 1 has to be adjusted depending on
the type of external dosing device connected. 25 bit is needed for dosing devices type 8XX, 8 bit by using a 685 Dosimat or a 700 Dosino.

2 Connection
700 Dosino
The 700 Dosino with the 8-pin MiniDIN plug type (2.700.0020) can be connected directly to the 822 Titration Curve Simulator. If you have a 700 Dosino with a 9-pin Sub-D plug type (2.700.0010) you need the
6.2134.020 adapter cable.
Note! With Titrandos with internal dosing drive (e. g. 808/835 Titrando) the 822 Titration Curve Simulator can only be connected to MSB 2 – MSB 4 because MSB 1 is occupied by the internal dosing drive.

2.2 Connection to the dosing interface

2.2.1 Connection to Titrinos by using an external dosing device
Connect the 822 Titration Curve Simulator with the connector cable
4 to the dosing input Dos 1 or Dos 2 of the Titrino.
Connect the dosing device to the Dosing device connection 6 of the
822 Titration Curve Simulator.
Connect the Analog Output 7 with the measuring input of the Titrino
using the 6.2116.020 cable.
Adjust the communication protocol 1 to 8 bit.
700 Dosino
The 700 Dosino with the 8-pin MiniDIN plug type (2.700.0020) can be connected directly to the 822 Titration Curve Simulator. If you have a 700 Dosino with a 9-pin Sub-D plug type (2.700.0010) you need the
6.2134.020 adapter cable.
The endpoint volume of certain Titrino models 736, 751 and 758 is approx. 50 % lower than the one specified for the curves. Please ask the Metrohm service to remedy this or use the internal dosing drive.

2.3 Connection to the remote interface

2.2.2 Connection to Titroprocessors
Connect the 822 Titration Curve Simulator to the 6.2134.010 adapter
box with the connector cable 4. Connect the adapter box with one of the dosing interfaces Dos. A1...4 of the Titroprocessor.
Connect the dosing device to the Dosing device connection 6 of the
822 Titration Curve Simulator.
Connect the Analog Output 7 with the measuring input of the Titro-
processor with the 6.2116.020 cable.
Adjust the communication protocol 1 to 8 bit.
700 Dosino
The 700 Dosino with the 8-pin MiniDIN plug type (2.700.0020) can be connected directly to the 822 Titration Curve Simulator. If you have a 700 Dosino with a 9-pin Sub-D plug type (2.700.0010) you need the
6.2134.020 adapter cable.
2.3 Connection to the remote interface
2.3.1 Connection to Titrinos with internal dosing drive
Connect the 822 Titration Curve Simulator with the connector cable
4 to the remote interface of the Titrino.
Connect the Analog Output 7 with the measuring input of the Titrino
with the 6.2116.020 cable.
The adjustment of the communication protocol 1 does not matter in
this case.
Switch on the activation pulse of the Titrino under parame-
ters>preselections.
Note! The parameter activate pulse does not exist for the 701 and 787 Titrinos. The conditioning must therefore be switched off so that a KF titration can be simulated.
6 822 Titration Curve Simulator, Instructions for Use
2 Connection
The Titrinos 701, 702, 716, 718, 719, 720, 721, 736, 787 and 794 work with only 6000 pulses per cylinder volume. This means that the EP vol­umes received have to be multiplied by 0.6.
The 751 and 758 Titrinos with program version 0020 do not provide the required pulses on the remote interface. For this device combination you either need an update of the Titrino program software or you have to use the 6.2148.000 remote box.

3.3 Conditioning and Karl Fischer titration

Turn the curve selector 2 to position "3" for simulating a Karl Fischer ti­tration (except with 701, 787 Titrino; see following page).
Program a Karl Fischer method with conditioning and sample data re­quest. Start the conditioning. Start the titration as soon as "Conditioning OK" is displayed. The cylinder will be filled again. Now press the key "Sample Add" 3 and confirm the sample weight. The curve simulator changes internally automatically to curve "4". The illustration below shows an example of a simulated curve.
Endpoint at (26.15 ± 0.10) % of the cylinder volume
parameters: KFT Ipol with standard parameters 5 mL exchange unit
822 Titration Curve Simulator, Instructions for Use 9
3.3 Conditioning and Karl Fischer titration
Procedure with 701, 787 Titrino:
Turn the curve selector 2 to position "4".
Program a Karl Fischer method without conditioning but with sample data request. Start the titration and confirm the sample weight.
Note! The endpoint of the conditioning curve "3" is at 10 % of the piston stroke with Curve Simulators of the series 02 and 03 but at 8.4 % for those from series 04 (see serial number, page 2). By reconditioning with Curve Simulators of the series 02 and 03 the status "Conditioning OK" will never be reached because the cylinder will be filled at 10 % of the piston stroke.

4 Appendix
Meaning of the red status LEDs:
DAISY:
With the serial protocol several devices can be at the same bus one af­ter the other in a so-called daisy-chain configuration but only one of them is active. The so-called daisy signal is produced with SHIFT, STROBE and the momentary condition of SER_IN to switch to the next device.
COND.:
When "Conditioning OK" is displayed on the titrator, no further pulses are coming from the titrator and the voltage at the "Analog Output" 7 remains at the same level. The air humidity is not simulated. After press­ing "Sample Add" 3 the LED "COND" is switched on to show that the Karl Fischer curve is running now.
SIMI NOT OK:
When switching on the titrator a self test of the internal reference and supply voltages is carried out in the 822 Titration Curve Simulator. The self test is carried out also at a reset of the Curve Simulator caused by rotating the cock at the dosing device or a reset command on a serial transmission. After the self test the display changes to "SIMI OK".
Meaning of the green status LEDs:
CURVE STATE:
If the 822 Titration Curve Simulator recognizes pulses for ejecting at the dosing device, the LED "CURVE STATE" starts blinking i.e. it stays dark for 500 pulses and bright for the next 500 pulses and so on.
CURVE 6000:
not in use
CURVE 20000: If dosing is done with a 805 Dosimat or with the internal dosing drive of the Titrando and a stroke with 20'000 pulses is ejected, this LED is blinking synchronously with the LED "CURVE STATE".
SIMI OK:

4.5 Warranty and conformity

4.5.1 Warranty
The warranty on our products is limited to defects that are traceable to material, construction or manufacturing fault which occur within 12 months from the day of delivery. In this case the defects will be rectified in our workshops free of charge. Transport costs are to be paid by the customer.
For day and night operation the warranty is limited to 6 months.
Glass breakage in the case of electrodes or other parts is not covered by the warranty. Checks which are not a result of material or manufac­turing faults are also charged during the warranty period. For parts from outside manufacturers, insofar as these constitute an appreciable part of our instrument, the warranty stipulations of the manufacturer in ques­tion apply.
With the regard to the guarantee of accuracy the technical specifica­tions in the instruction manual are authoritative.
Concerning defects in materials, construction or design as well as the absence of guaranteed features the purchaser has no rights or claims except those mentioned above.
If damage of the packaging is evident on receipt of a consignment or if the goods show signs of transport damage after unpacking, the carrier must be informed immediately and a written damage report demanded. Lack of an official damage report releases Metrohm from any liability to pay compensation.
If any instruments and parts have to be returned then the original pack­aging should be used if at all possible. This applies above all to instru­ments, electrodes, buret cylinders and PTFE pistons. Before embed­ment in wood shavings or similar material, the parts must be packed in a dustproof package (for instruments the use of a plastic bag is essen­tial). If open assemblies are included that are sensitive to electromag­netic interferences [fields] (e. g. data interfaces, etc.) then these must be returned in the associated original protective packaging (e. g. con­ductive protective bag). (Exception: assemblies with a built-in voltage source belong in non-conductive protective packaging.)
For damage which arises as a result of non-compliance with these in­structions, no warranty responsibility whatsoever will be accepted by Metrohm.
