Page 17: Advice On Pipe Work And Detector Installation
Engine Oil Mist Detection System MULTIPLEX ADVICE ON PIPE WORK AND DETECTOR INSTALLATION The Detectors are mounted upright - see drawing QMI-05-1099 Part 2-8 Make sure the Detectors are mounted on the down side of the engine rotation - see drawing QMI-05-1099 Part 2-8 The Baffles must be mounted vertically so that oil does not become trapped in the Baffle.
Page 18: Detector Mounting And Location
RETROFITS When a QMI MULTIPLEX Oil Mist Detection System replaces another system, the same entry points into the crankspace may be used. In this instance use an elbow after entering the crankspace and attach a baffle to the sampling end of this elbow.
Page 19: Layout Of Pipework
Engine Oil Mist Detection System MULTIPLEX LAYOUT OF PIPEWORK PIPEWORK LAYOUT See drawing QMI-05-1098 Part 2-6 The pipework for the MULTIPLEX system should be laid in such a way that there are no low points for condensed oil mist to collect. Failure to lay the pipes properly may cause a blockage thus affecting the efficiency of the system.

Page 42 Engine Oil Mist Detection System MULTIPLEX QMI MULTIPLEX 4-20MA DATA LOGGER OUTPUT It is useful to be able to record the level of oil mist present in the crankspace or gearbox. The data collected can be used to determine the cause of a build-up towards a possible explosion and help find a solution.
Page 43 Engine Oil Mist Detection System MULTIPLEX WIRING FOR ENGINE SLOW/SHUTDOWN The Individual Shutdown for up to two engines is built into the Monitor Channels, 1 - 6 are for one engine and 7 - 12 are for the other engine. You can have either a closed contact that opens on Shutdown or an open contact that closes on Shutdown, this must be specified at time of ordering.

Page 46 Engine Oil Mist Detection System MULTIPLEX OPERATION Oil mist is continuously drawn through each Detector by a fan which we insist must be kept running at all times so that the oil mist level can be monitored even if the engine is not operating.
Page 47 Engine Oil Mist Detection System MULTIPLEX OPERATION - continued BEST PRACTICE Always re-set the Monitor so that each Detector has the new maximum programme setting. The first relay activates at 80% and is an early warning alarm. The second alarm relay is the main alarm and the third alarm or Shutdown is activated at 100%.
Page 48 Engine Oil Mist Detection System MULTIPLEX Fan Failure Housing Light Sequence LIGHTS MEANING FLASHING GREEN LIGHT Fan has just started up. GREEN When the fan reaches normal running speed, the light will change to a solid green light. SOLID GREEN LIGHT GREEN Fan is running normally and magnetic sensor is working.
Page 49 MULTIPLEX TO CHANGE ALARM LEVELS The QMI MULTIPLEX System is pre-set. However should the settings require adjustment and the alarm level set lower, then the procedure is as follows: During the setting-up procedure normal operation of the CMU is disabled.
Page 50 Engine Oil Mist Detection System MULTIPLEX TEST SEQUENCE & ALARM LEVELS Before beginning the test sequence, inform all relevant personnel. To activate the test procedure: Place the Magnetic Pen over the circle marked ‘TEST’ The sequential testing will commence as follows: Testing indicators will illuminate Software Version - 1.03 followed by all operational LEDs illuminating in the order below: Operating...
Page 51 CHANGING THE NUMBER OF DETECTOR HEADS Setting up the QMI MULTIPLEX System CMU for a different number of Detector Heads. The QMI MULTIPLEX can have a total of 12 Detector Heads plugged into it. The display will show 12 positions illuminated.
Page 52 8 to 12 as flashing amber, green and red lights. Also the display reading will show ‘F1’ fault. To correct or change the QMI MULTIPLEX to show only 7 channels and cancel the other Switches showing, the following procedure is carried out: Turn off QMI MULTIPLEX Monitor to switch off the system.

Page 64 MULTIPLEX MAINTENANCE PROCEDURES The QMI MULTIPLEX comprehensive fault finding program greatly simplifies the fault analysis procedure. Fault indicators, whether operational or component breakdown, are built into the program. In the event of their occurrence a fault code (listed in the Fault Directory on the right hand side of the display fascia) is displayed digitally against the faulty channel number.
Page 65 Engine Oil Mist Detection System MULTIPLEX LENS CLEANING PROCEDURE he need for lens cleaning will be indicated by Code “F2” against the relevant channel on the CMU. See diagram in Part 5-5 in connection with the cleaning procedure. To clean the lens in the event of oil or condensation build up: Disconnect the 6-way connector on the rear of the Detector Head.
