Page 6: Cautions & Warnings
Dispose lamp at a waste disposal place which is qualified to handle mercury containing lamps. If you cannot find a respective place, return the lamp to BMT MESSTECHNIK GMBH. Warning: Before opening the sample gas filter make sure that the sample line does not contain ozone gas, and is not under an overpressure. -
Page 7: Précautions
Précautions Avertissement : L’ozone est un gaz à forte toxicité. Les concentrations d’ozone mesurées à l’aide de l’analyseur d’ozone BMT 965 vont au-delà de la limite mortelle. C’est pourquoi il convient d’utiliser une technique de sécurité adéquate (détecteur d’ozone). Avertissement : Ce produit présuppose une installation électrique en bâtiment qui assure la protection contre les surintensités et contre les courts-circuits. -
Page 8: Installation And Power Connection
Installation and Power Connection The OZONE ANALYZER BMT 965 is a 144 x 72 mm front panel instrument (according to DIN 61554). For additional information on other variants of the BMT 965 (AQ, Cabinet etc.) con- sult the appropriate appendix of this manual. - Page 9 OZONE ANALYZER BMT 965 Manual, Rev. 01/2024 Warning: This product relies on the building's installation for short-circuit (overcurrent) protec- tion. Ensure that a fuse or circuit breaker no larger than 15 A at 120 VAC (10 A at 240 VAC) is used on the phase conductor.

Page 10: Photometers And Dirt
BMT ozone analysers for gaseous ozone are equipped with particle filters containing a replaceable filter insert. The filter inserts should from time to time be checked for dirt (see page 52, Mainte- nance), and be replaced on a regular basis depending on the degree of particle content of the sample gas. - Page 11 OZONE ANALYZER BMT 965 Manual, Rev. 01/2024 ___________________________________________________________________________...

The binary input is a control input used to trigger the ZERO function of the OZONE ANALYZER BMT 965. By applying a voltage of typically +24 VDC between pin 11 (+) and pin 10 (-) for about 0.5 seconds the instrument will be zeroed. The ZERO function may be... -
Page 13: Binary Outputs
OZONE ANALYZER BMT 965 Manual, Rev. 01/2024 Input current at the binary input is approx. 8 mA. The input is protected against voltages with wrong polarity. Binary Outputs The binary outputs are relay contacts, which are used to signal errors and alarms. An additional contact can be used for the selection of purge gas during automatic zeroing. -
Page 14: Usb-Interface
It is very important to really make sure that no ozone is present in the cuvette during zero- ing! Before zeroing the BMT 965 has to be purged with oxygen or filtered air. ___________________________________________________________________________... -
Page 15: Automatic Zeroing With Control Of Purge Gas
Automatic Zeroing with Control of Purge Gas Purge gas control can be taken over by the BMT 965. The relay contact Purge (Pin 2) is used for this purpose. This contact (max. 28 V, 0.5 A) can switch an ozone proof solenoid valve to switch from ozone to an ozone free gas like CDA (Compressed Dry Air) or Oxygen. -
Page 16: Front Panel Operation
In case the OZONE ANALYZER BMT 965 is equipped with an Internal Purge Unit (solenoid valve and air pump with particle filter) as an option, e.g. in the model BMT 965 BT (see Appen- dix B) the terminal 2 should not be connected externally. -

Page 32: 10 Error Handling And Early Warnings
10 Error Handling and Early Warnings The BMT 965 has diverse possibilities to recognize errors, to signal them and to early-warn against them. Errors and Early Warnings are displayed on the front panel. Depending on the importance of the error, the Error Relay (pins 1 and 3) as well as the Early Warning contacts Lamp Low (Pin 9) or Cuvette Dirty (Pin 14) are activated (opened). -
Page 33: Lamp High Error
The lamp contains significantly less than 5 milligrams of mercury. Mercury is a poison. Dispose lamp at a waste disposal place which is qualified to handle mercury containing lamps. If you cannot find a respective place, return the lamp to BMT. Cuvette Dirty Warning In each zeroing the dirtiness of the cuvette is measured and displayed. -

BMT 965ST for the measurement of ozone in gas. The BMT 965 AQ is a SENSOR because it does not have a display. It is designed to directly be connected to e.g. a workstation via a 4-20 mA, or 0-10 V, signal line. The workstation also has to monitor and control the instrument's functions like auto-zeroing, or possible failure indications. - Page 62 Zeroing has to be initiated by pressing the push button ZERO at the optional REMOTE DISPLAY BMT 965 RD, or via the binary input at pins 5 and 6 of the signal connector, or RS-232, or USB (for details see the main part of the manual). Prior to zeroing the analyser, it has to be assured that the cuvette is filled with water having zero ozone concentration.
