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:
1. Testing indicators will illuminate Software Version - 1.03 followed by all operational LEDs
illuminating in the order below:
Operating (GREEN)
Warning (AMBER)
Alarm (RED)
2. All Digital readouts will indicate ‘8’
followed by:
All Digital readouts will then indicate ‘111’ showing that all segments of the numerical
display are working without fading.
3. Each Sensor lens will be indicated thus:
‘Cd’ Clean Sensor – indicates clean lens
‘dd’ Dirty Sensor – indicates lens meaning that the lens are less than 80% clean and ‘F2’
will appear on the display; if ignored, the display will show ‘F3’.
4. All external relays, with the exception of the functional relay will operate for 10 seconds.
The test includes a test of the fault monitoring circuit when ‘F9’ will appear momentarily.
‘F9’ permanently displayed indicates a Monitor failure and the Power Supply Board will
need replacing.
5. Final part to the test is the ‘No CPU’ Light which will flash once or twice depending on
what part of the data cycle it is in. Both once or twice are normal to show the CPU is
functioning.
6. After the Test Sequence is completed the Monitor will automatically return to display the
channel with the highest oil mist reading.
7. After ‘Power On’ or ‘Reset’ procedures are implemented and completed, the relay
outputs are inhibited for 2 minutes, this also applies in the event of an alarm.
Therefore two full minutes must pass to enable the system to reset. This is to allow the
software to latch back into the correct running mode, otherwise erroneous signals may
be displayed. During this sequence, the isolated Sensor may be displayed ‘Cd’.
8. During the Test Sequence should any function fail to operate as specified, refer to the
fault finding section.
