General description Triple Plus+ and Triple Plus+ IR I. General Description Triple Plus+ The Crowcon Triple Plus+ is a microprocessor controlled portable gas detector which is capable of monitoring up to four gas types simultaneously and providing warning of hazardous levels. Using electrochemical, catalytic and thermal conductivity sensors, the instrument may be configured to detect any practical combination of oxygen, toxic and flammable gas. See Appendix 4 for notes on sensor limitations.
Triple Plus+ and Triple Plus+ IR (b) (c) (d) (e) General description No damage caused by exposure to high gas concentrations No poisoning effects Ability to measure at % volume levels as well as %LEL Fail safe It must be remembered however that an infrared hydrocarbon sensor will have no response to hydrogen and is therefore unsuitable for use where hydrogen forms a significant part of any potential flammable risk.
Operation Triple Plus+ and Triple Plus+ IR II. Operation 2.1 Switch On Press the 'ON' button to switch on the Triple Plus+/Plus+ IR. The instrument will display the message 'Crowcon Triple Plus+/Plus+ IR' and the serial number. The unit will test the red alarm LED, sounder and alarm beacons. Press the UNMARKED button to silence the alarm. Note: if the unit is in the presence of a hazardous gas the alarm will continue to operate. If alarms are configured to mute (see MUTE in section 3.
Triple Plus+ and Triple Plus+ IR Operation 2.2 Display The information on the display is dependent on the type of sensors installed in the instrument. For each sensor module installed, the display indicates the gas concentration, the units of measurement (e.g. ppm) and the channel name (e.g. H2S). (Each sensor module contains analogue circuitry to support the sensor and a small digital memory which identifies it to the processor along with calibration data and alarm thresholds.
Operation Triple Plus+ and Triple Plus+ IR level by pressing the UNMARKED button. The peak gas level will then be displayed again from then on. In addition to the messages described above, if alarms are muted the message ‘MUTED’ will flash with the sensor name and units. 2.
Triple Plus+ and Triple Plus+ IR Operation the whole display with the warning. All instantaneous alarm types are latching which means that they may only be reset by pressing the UNMARKED button when the gas hazard has passed. If set up for Time Weighted Average (TWA) alarms, the Triple Plus+/Plus+ IR triggers a non-resettable alarm if a short term (normally 15 minute) or long term (8 hour) exposure level is reached.
Setting Up Triple Plus+ and Triple Plus+ IR III. Setting Up The Triple Plus+/Plus+ IR has been designed to display as much or as little information to the user as is required by the controller of the equipment. On the one hand it is a four channel measuring instrument with continuous readout, on the other, a basic alarm only detector with status display and no way of switching it off. This section describes how to tailor the instrument to the application via the front panel buttons.
Triple Plus+ and Triple Plus+ IR Setting Up How to change an option To change an option, use the first two keys, labelled with the << and >> symbols, to change the current selection, and the third key (labelled QUIT) to finish changing the selection. If the QUIT key is pressed and the parameter has been modified then the user is prompted with a save changes message. Two keys are soft key function labelled, one with YES and one with NO. Press the desired button.
Setting Up Triple Plus+ and Triple Plus+ IR 3.2 Configuration Options LIGHT: Configures the backlight timeout option to be NEVER TIMEOUT, 10 MINS., 20 MINS., 30 MINS., or ALWAYS ON. Whatever option is selected, the backlight will always come on when the instrument is in alarm. DISPY Display mode. Configures the instrument display mode, with one of the following options: Normal, Average, Off, TWA Toxic, Peak Hold. These are described in the section III Operation.
Triple Plus+ and Triple Plus+ IR Setting Up ZERO enables the option of zeroing the sensors at start, as per the zero all option above – the prompt to zero the sensor will appear several seconds after start up (to give the sensors time to settle) and will timeout (without performing a zero) if the YES button is not pressed within about 5 seconds. LOG enables data logging at start up, and ZERO & LOG enables both zero and data logging at start up. Select NOTHING to disable zero and logging at start up.
Setting Up Triple Plus+ and Triple Plus+ IR modules. The exact list of gases and their corrections are configurable via a PC using Portables PC software. The default of gas correction factors for flammable gases with respect to methane and pentane are listed in Appendix 2. Note: if no table has been downloaded into the instrument then no correction factor can be selected (the only option is NO CORRECTION).
Triple Plus+ and Triple Plus+ IR Setting Up IMPORTANT SAFETY NOTICE: All units fitted with sensors to measure both %LEL AND %Volume Methane, other hydrocarbons or “flammables” To avoid potential damage to the pellistor sensor used for measuring % LEL methane when calibrating the IR or thermal conductivity sensor used for measuring % volume methane, the following precautions must be observed.
Setting Up Triple Plus+ and Triple Plus+ IR OFF Two options: OFF ENABLED, OFF DISABLED. Determines whether the instrument can be switched off. MUTE If the mute function is enabled (which can only be done via Portables PC, see section 3.5. PC interface and software) then a MUTE option will appear within the menu system. This option can be selected as either SILENT ALARMS or AUDIBLE ALARMS.
Triple Plus+ and Triple Plus+ IR Quickcal 3.3 Quickcal The instrument has the ability to perform a ‘quick calibration’ of four gas channels: CH4; CO; H2S and O2 in ‘one go’. The system prompts the user through the procedure. Before QuickCal is initiated, the instrument should have been zeroed. Now follow this procedure: Press both of the middle 2 buttons, and hold them down for 5-7 seconds.
Pellistor saving Triple Plus+ and Triple Plus+ IR Additionally, a pellistor will switch itself off if it reaches a reading of 105% LEL or more – this action will happen irrespective of whether a % volume sensor is also fitted. If a pellistor switches itself off then it will stay off until it is manually switched on. This happens by pressing the unmarked button. The pellistor will warm up for 5 seconds before the pellistor channel will read.
Triple Plus+ and Triple Plus+ IR Configuration options tor, and the actual correction factor itself may be modified (Pellistor only). INSTANTANEOUS ALARM LEVELS The gas level at which instantaneous alarms are triggered. This configuration data is available for all sensor channels with sensors having 3 rising alarm levels, except oxygen which has 2 falling and 1 rising alarm level.
Battery Charging Triple Plus+ and Triple Plus+ IR IV. Battery Charging The new LIBRA Lithium-ion battery pack must be charged for a full 12 hours before first use. This will ensure the life of the new battery. A ferrite clamp is included with the Li-ion battery pack. Install the ferrite clamp to the D.C. charging lead as shown. The new CROWCON battery pack consists of a rechargeable Lithiumion battery pack.
Triple Plus+ and Triple Plus+ IR Battery Charging If the instrument is to remain unused for a length of time, it should be charged prior to the period of storage. Due to the safety circuitry included within the Lithium-ion battery pack, the battery will discharge when the unit is not in use. Always charge fully before use, or store on charge.
Data Logging Triple Plus+ and Triple Plus+ IR V. Data Logging The data logging aspect of the instrument can be configured to be active when the instrument is switched on by the START menu option. Additionally, the instrument records events (such as alarms) and an event will cause the logger to be switched on. Data is logged for all gas channels at a rate set by the log period, which is configurable via Portables PC software.
Triple Plus+ and Triple Plus+ IR Troubleshooting Guide VI.
Maintenance and Calibration Triple Plus+ and Triple Plus+ IR VII. Maintenance and Calibration Crowcon recommends monthly gas response checks and a recalibration interval of 6 months. Flammable sensors will respond to hydrogen and most hydrocarbons but will only be calibrated for a specific gas, typically methane. Note: when the instrument is placed into a charger or charger/interface which is fitted with the new LIBRA lithium-ion battery pack the unit will turn off and start charging.
