5.3.5 Simulation.

According to MEPC 107(49) § 4.2.5, onboard testing according to the
manufacturers instructions shall be permitted.

To facilitate this the JOWA 15ppm bilge alarm has a service menu called
simulation. A simulation run permits the user to imitate a ppm over the alarm set
point, (max alarm set point 15ppm).

This simulation run works by simulating the ppm ramping up from the real ppm
to a peak of 20ppm and down to the real ppm again.

-In this case “real ppm” refers to the ppm which is actually present.

Each ppm step in the simulation run takes 2 seconds. If, for example, the real
ppm is 10ppm when the simulation is started the alarm counts up from 10ppm
to 20ppm. If at the end of this simulation the real ppm is now 8ppm the count
down stops here


NOTE!
-If the real ppm value is higher than 15ppm then it is not possible to start a
simulation run
-During simulation the alarm continually monitors the real ppm in the
background. If at any time during a simulation run the real ppm goes higher
than 15ppm, there will be an alarm.
-All simulation runs are logged if the Sep in signal is active.
