M5 | Functional test with smoke test to be carried out.
CAUTION!
The oil mist alarm will now be triggered, showing alarm LED lighting up and the engine will
be shutting down/reducing the RPM.
1. Remove the plug in the
inspection cover.
2. Install the test plug at the
inspection cover.
3. Bend the smoke house
until tube content break.
4. Pull the hose into the test
pump.
6. When the oil mist concentration is high, the LED indicator will
increase and at 70% opacity of the set alarm threshold, the “Oil
Mist Alarm” LED turns on. At 100% opacity relative to the set
alarm threshold, the “Oil Mist Alarm” LED will start flashing. If
the opacity subsequently decreases, the alarm status is saved.
The opacity is displayed on the LED level indicator on the right.
If the top LED comes on, the opacity has reached/exceeded the
oil mist alarm threshold. The alarm condition can only be reset
by pressing the oil mist alarm reset button.
5. Pump smoke until the
oil mist alarm is realised.
7. Each extraction point is now checked individually. To do this,
hold the smoke tube directly under the suction funnel of the
individual extraction point and perform at least 3
– 5 pumping
strokes. The resulting smoke should now be drawn out directly
via the suction funnels. After no more than 10 seconds, the oil
mist detector should indicate an alarm on the measuring head
display. The time to display varies depending on the engine type
and the installation kit.
