Page 6: Introduction To Tvoc 2
Units TVOC 2 gives a continuous 4-20 mA output which can be integrated into a DCS control system to give an indication of VOC levels in the operating environment. Note the 4-20 mA output must be externally powered with 8-35 V. - Page 7 TVOC 2 Intrinsically safe certificate for further details. The TVOC 2 safety rating permits its deployment in all hazardous areas of the quoted (or less demanding) rating. For detail please refer to the marking on your instrument (found on the front main label). Units are manufactured with two protection concepts applied by separate certifications.

Page 15: Initial Calibration
TVOC 2 is calibrated at Ion Science before dispatch using 100 ppm Isobutylene. However, if you wish to calibrate your TVOC 2 after installation, Ion Science recommends the unit is left to run on its chosen settings (see ‘TVOC 2 Set-up Section’) for 24 hours before an initial calibration is carried out, to allow the instrument to stabilise. -
Page 16: Operation
Ion Science Ltd Operation Start-Up After electrical power is connected, TVOC 2 runs through a ‘Start-up’ routine, which lasts for approximately 1 minute. During this ‘Start-up’ routine TVOC 2 demonstrates the following characteristics: • The LCD screen displays the software version number •... -
Page 17: Selector Pins
Selector pins TVOC 2 has a range of options that are selected via the selector pins on the back of the main PCB (please see the ‘TVOC 2 Set-up’ Section). The options are shown below with the defaults highlighted in bold: 1-1000 ppm 0.01 –... -
Page 18: Calibration Routine
Calibration Calibration routine Ion Science recommends calibrating TVOC 2 after any maintenance or lamp cleaning is carried out and on a 3 monthly basis to ensure TVOC 2 is working to specification. NOTE: Please read this entire calibration procedure before attempting a calibration. -
Page 19: Setting The Span Gas Concentration
An acceptable ZERO calibration level will result in the illumination of the ‘STATUS LED’. An unacceptable ZERO calibration level will result in the illumination of the ‘FAULT LED’. Should this occur the TVOC 2 will not proceed to the gas tolerance setting and return to normal operation the previous calibration levels will be used. - Page 20 Now place the magnet over the logo to return to normal monitoring routine. The green ‘STATUS LED’ will begin flashing as TVOC 2 starts. IMPORTANT: Unacceptable calibration levels will not be adopted; the instrument will default to the previously stored acceptable calibration.

(IS) or not. For IS or Zone 2 applications the unit must be inspected and have the fuse replaced by Ion Science Ltd or an Ion Science Approved Service Centre. The intrinsically safe rating is not maintained if the fuse is simply replaced. -
Page 25: System Recommendations
Gas sample systems It is sometimes necessary to pump or draw a gas sample past the TVOC 2. For this a “Flow Adaptor " can be fitted. The flow adaptor has an inlet and an outlet port so that gas may be pushed or drawn across the sensor. See Diagram 22 above. - Page 26 2. The pressure difference of a pumped system relative to atmosphere should be minimised to avoid the effects of gas law. 3. The maximum pressure that can be applied to the TVOC 2 sensor housing is 300 mbar. However, this is not a recommended working pressure. Ideally working pressure should be +/- 30 mbar relative to ambient pressure.
