Observing different firing orders
For the firing order, a differentiation must be made between the sequence
in which the outputs are switched at the ignition controller, and the
sequence in which the cylinders are fired. These sequences depend on how
the outputs of the ignition controller are wired to the engine's ignition coils.
For example, based on the wiring, a 6-cylinder engine can have the
following firing order:
– Output firing order on MIC500: A-B-C-D-E-F
– Cylinder firing order of engine: 1-5-3-6-2-4
8.6.4 Self Test
Operational safety!
If you conduct a self test, ensure that the following conditions are met in
order to avoid equipment damage or personal injury:
– The MIC500 ignition controller may not be located in a potentially
explosive area.
– The gas supply must be switched off.
– There may not be any residual gas in the combustion chamber.
Please note that by activating this view, the self test starts immediately. Information on the use
of the self test function for troubleshooting can be found in chapter Running a Self Test on
page 116.
