Statements Responsibility for use TVOC detects a large range of gases, which are potentially dangerous from both a poisoning and/or an explosive perspective. TVOC has a number of selectable features allowing the detector to be used in a variety of applications. Ion Science Ltd can accept no responsibility for the incorrect adjustment of features that cause harm or damage to persons or property. -
Page 6: Introduction To Tvoc
Duty cycle 5 seconds ON / 55 seconds OFF TVOC 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. In addition to the 4 – 20 mA output TVOC has an LCD display showing gas concentration and 4 colour LED’s. - Page 7 TVOC ATEX or IECEx certificate for further details. The TVOC 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). As of 1 October units will be manufactured with two protection concepts applied by separate certifications.

TVOC Setup 4.1 Selector Pins TVOC has a number of settings that can be selected by the user via a row of 4 selector pins mounted on the reverse side of the main PCB. Diagram 4.1 shows the location of the functional selector pins labelled - A, B, C &... -
Page 10: Cycle Times
0 to 5 minutes in 1 second increments. The 4 – 20 mA output is updated at the end of each cycle. As standard the TVOC duty cycle is 1 minute – the lamp is ON for 5 seconds and OFF for 55 seconds. -
Page 11: Installation
Mount TVOC in an area that has good air circulation. Restricting natural air current may result in delayed detection. Never mount TVOC in direct sunlight or over a heat source such as a radiator. This may cause TVOC to exceed its certified working range. ... -

Page 14: Initial Calibration
TVOC is calibrated at Ion Science before dispatch using 100ppm Isobutylene. However if you wish to calibrate your TVOC once it is installed Ion Science recommends that the TVOC is left to run on its chosen settings (see page 9TVOC Set up) for 24 hours before an initial calibration is carried out, to allow the instrument to settle into the working environment. -
Page 15: Operation
Operation 6.1 Start Up After electrical power is connected, TVOC runs through a ‘Start up’ routine, which lasts for approximately 1 minute. During this ‘Start up’ routine TVOC demonstrates the following characteristics: * The LCD screen displays the software version number * The GREEN LED flashes * The 4 –... -

Please see Section 7 Calibration for YELLOW LED status. 6.4 Selector pins TVOC has a range of options that are selected via the selector pins on the back of the main PCB (please see page 9TVOC Set up). The options are shown below with the defaults highlighted in bold: 1-1000ppm 0.01 - 10 ppm or 0.1 - 100 ppm... -
Page 17: Calibration
Calibration 7.1 Calibration routine Ion Science recommends calibrating TVOC after any maintenance or lamp cleaning is carried out and on a 3 monthly basis to ensure TVOC is working to specification. NOTE: Please read this entire calibration procedure before attempting a calibration. -

Luer fitting; only a ¼ turn is required. Switch on the gas supply and then place the magnet over the logo. The SPAN LED will flash and TVOC will display the direct millivolt (mV) output from the PID sensor. Now remove the magnet. Calibration adaptor... - Page 19 Now place the magnet over the logo corner to return to normal monitoring routine. The GREEN LED will start flashing as TVOC starts its cycle with a lamp ON cycle. If either the ZERO and/or SPAN levels where outside acceptable levels the RED LED will flash until an acceptable calibration has been carried out.

Page 22: Fuse Rupture And Replacement
NOTE: Always calibrate TVOC after servicing is carried out. Fuse rupture and replacement TVOC has a 125 mA BASEEFA certified fuse to provide instrinsically safe protection when the unit is installed in hazardous areas. This fuse may ruptures for example due to over voltage or a current surge, if this is the case replacement is different depending upon the application being Intrinsically Safe or not. -
Page 23: Instrument Warranty And Service
Service Ion Science is pleased to offer a number of service options on our TVOC product range that allow you to choose the instrument cover that best suits your needs.

Page 24: Diagnostics
TVOC MANUAL Ion Science Ltd Diagnostics Below are two conditions your TVOC can be in when it is working correctly: The two conditions shown below are of the instrument in an error state with potential checks/cures for these faults: If an F1 error occurs when the instrument is first switched on there may not be an issue. The instrument needs to be left on for a few cycles to see if the lamp strikes on its own. - Page 25 If you do not have any spare pellets, lamps or PID cells then you will need to contact Ion Science for some assistance if the problem remains after the instrument has completed a few minutes of run cycles and the cable has been checked.
