Performance test with cigarette smoke or SCHALLER AUTOMATIONS OIL MIST
SIMULATOR (Part No. 10353) (to be performed only when engine is not running)
- Open crankcase-cover of a compartment in order to access
a suction pipe or sampling funnel.
- Fill the plastic bag (found in the service box) with cigarette smoke by use of the
mouth piece or use OIL MIST SIMULATOR.
- Affix the plastic bag to suction pipe or sampling funnel.
- Allow the oil mist detector to draw in the distillate vapour for
a minimum of 20 seconds.
It depends on the vapour density and suction time (at least 20 seconds):
1 - whether an oil mist alarm is triggered, or
2 - oil mist alarm is triggered, and a search run is started, or during
the search run only one half or the engine is indicated, or the
affected compartment is indicated.
(If the amount of vapour is insufficient or the suction time is too short, a wrong
compartment may be indicated in the display window of the valve box.)
