131 Collecting Cone (02000-A-1642) The detection of a lighter than air gas is enhanced by the use of a Collecting Cone. The cone fits onto the Sensor accessory thread in place of the Filter Housing and retains the filter. The appropriate filter must be fitted. A nozzle on the cone permits gassing of the Sensor with the cone in position.

133 Sample / Calibration Gas Flow Adaptor (1226A0411) A Flow Adaptor provides a facility to allow sampling of a closed system by means of two pipelines. The Flow Adaptor is fitted to the sensor accessory thread by a locking ring that enables the Flow Adaptor to be removed without disconnecting the pipeline.

135 Duct Mount Kit The duct mounting kit (S3KDMK), combined with the MPD Interface Adaptor (1226A0382), can accommodate the MPD to detect flammable gases in a duct application. The duct mount kit includes the adaptor, gasket and required fasteners. The MPD Interface Adaptor includes only the adaptor and requires the S3KDMKduct mount kit.
2 Installation WARNING The Code of Practice regarding ‘Selection, Installation and Maintenance of Electrical Apparatus for use in Potentially Explosive Atmospheres’ must be complied with at all times. Refer to the appropriate local and/or national regulations relative to the installation site. Elsewhere the appropriate local and/or national regulations should be used.
24 Wiring NOTe: To maintain EMC integrity, wiring must be shielded by either an integral shield or run through conduit or pipe. Shield should provide 90% coverage. The MPD Sensor must be operated from a transmitter supplied by a Class 2 Power Supply.
25 Fitting Sensors WARNING Before installing the sensors, isolate the power supply by disconnecting or removing the associated control module from the installation. CAUTION • The sensitivity of catalytic sensors is impaired by silicone compounds. Do not expose the sensors to silicones or silicone-based products. •...
3 Fitting Accessories 31 Collecting Cone (02000-A-1462) To fit the Collecting Cone to a sensor, carry out the following: 1. Remove the Filter Housing and gasket from the sensor. 2. Fit the Stainless Steel Filter. 3. Screw the Collecting Cone onto the sensor accessory thread and tighten firmly by hand.
4 Maintenance 41 General Maintenance consists of cleaning the sensor and accessories, replacing gasket and the Hydrophobic Barrier and gassing the sensor when testing the system. CAUTIONS • The sensitivity of Catalytic Sensors is impaired by silicone compounds. Do not expose to silicones or silicone based products. •...

6 Functional Gas Test (Bump Test) 61 Sensor without Accessories Where there are no accessories fitted, it is recommended that a Flow Adaptor is used when gassing the sensor. Where this is not possible, a suitable plastic bag may be used. 62 Sensor with Collecting Cone or Weatherproof Cap 1.
The calibration procedure should only be performed by qualified personnel. NOTe: Honeywell Analytics recommends that the maximum calibration interval be 6 months or in accordance with customer site procedures, whichever is sooner to assure the highest level of safety. Correct operation of each sensor/detector should be confirmed with test gas of known concentration before each use.

72 Cross Calibration procedure for MPD-CB1 CAUTION Where the user calibrates any sensor using a different gas, responsibility for identifying and recording calibration rests with the user. Refer to local regulations where appropriate. When the MPD-CB1 Combustible LEL sensor is to be calibrated with a gas which is different to the gas or vapor to be detected, the following cross calibration procedure should be followed: NOTe...

* Rating of * Rating of Gas to be Detected Calibration Table 2. Meter Settings 4. If a sensor is to be used to detect a gas other than that for which it was calibrated, the required correction factor may be obtained from Table 3. The meter reading should be multiplied by this number in order to obtain the true gas concentration.
NOTe Honeywell Analytics recommends that users verify the accuracy of their instruments using test gases wherever possible. Cross-referred measurements should be used as a guide only, not as absolute values.
