Page 3: Introduction
Introduction These operating instructions describe the installation, operation and programming of the combined process photometer ® and titrator Testomat 2000 TH/Cl. We recommend that, whilst familiarising yourself with the operation of the unit aided by this manual, you have immediate access to the unit in order to perform the functions and combinations as described. As certain functions are interrelated, it is advisable to follow the instructions in the given order. -
Page 4: Notes For The User
Notes for the user • Repeated switching 'on' and 'off': Wait at least for 5 seconds before you switch the unit repeatedly 'on' or 'off' at the main switch. • Observation of the environmental conditions: In order to guarantee a reliable operation, the unit must only be used under the environmental conditions described in the technical data. -
Page 5: Installation And Commissioning
Installation and commissioning Installation and commissioning must be undertaken only by authorised technicians! Installation The unit should be fixed vertically! Avoid tension of the housing. The unit doors swing to the left when they are opened. Please ensure that there is sufficient space for opening them. In this way, you facilitate the electrical installation and later maintenance and service work. -
Page 6: Commissioning
Commissioning 1. Full reagent bottles must be connected before commissioning and switching on. Attach the vacuum connection onto the reagent bottle using the union nut. Please observe the correct allocation of the reagents A, B and C to the dosing pumps: TH2025 = DOSIClip 1 (left), Cl2025A = DOSIClip 2, Cl2025B = DOSIClip 3, Cl2025C = DOSIClip 4 (right). -

Page 10: Status Display
Status display The display indicates active unit components. Description of relays outputs Flush external flush valve We recommend the fitting of a programmed flush valve upstream of the unit if, when installing the unit, the use of a long sampling tube is unavoidable Also, in cases where the unit is used for monitoring two measuring points, an external flush valve should be installed in order to prevent faulty measurements caused by mixing of the samples. -

Page 13: Function Characteristics
Measuring points switch-over The Testomat 2000 THCl enables the monitoring of 2 measuring points. The measuring points switch-over occurs automatically, but can be suppressed by a contact at input IN1. The active status of IN1 should be programmed correspondingly. -
Page 14: Setting The Timer
Setting the timer FLUSH TIMES/INTERVAL s s t t M E INTERNAL FLUSH TIME Internal flush External flush time In order to ensure the analysed sample represents the current value, the sampling Interval pause tube must be sufficiently well flushed taking its length into consideration. After the installation has been out of operation for a longer period, or in the case of long analysis intervals, it is sensible to select a flushing time in excess of 60 seconds. -

Logic functions of the limit value outputs LV1 and LV2 Schematic representation of logic function Logic function 0, Duration Output relay LV1 or LV2 pulls up when the measured value rises above limit value LV1 or LV2. If the measured value falls below the limit value LV1 or LV2 without lock out, the relevant relay drops out again. -
