9.1 Start-up
Before you start up the MIC500 ignition controller, take note of the following:
– Does the ignition sequence fit the engine? If you are unsure, contact MOTORTECH or the
corresponding engine manufacturer.
– Ensure that the firing order of the engine and/or the wiring of the output cable harness are
carried out correctly.
– Is the pickup wired correctly (see chapter Input Wiring – Pickup on page 54)?
– Is the distance of the pickup to the trigger disc, reluctor pins, etc. set correctly (see chapter
Input Wiring – Pickup on page 54)?
– Ensure that the configuration is correctly stored in the device.
– Digital input configured as Switch Start/Stop:
Check whether the start/stop input is set to Firing active, or whether it works according to
the control requirements of the master control.
– Digital input configured as Switch A/B:
Check whether the input contact for schedule A/B is functions and ensure that the correct
schedule (A or B) is selected for start-up.
– Ensure that no gas is present in the inlet and exhaust systems before you start the engine.
– Ensure that the gas valve is closed.
– Perform the normal engine start-up process while the gas valve is closed (start only).
– Connect a stroboscope to the first firing cylinder (cylinder #1) and check whether the timing
point set on the ignition controller coincides with the actual timing point on the crankshaft.
If the ignition timing does not coincide exactly, change it until an optimal setting is reached.
If the ignition does not fire, read the instructions in section Troubleshooting and Eliminating
Errors on page 113.
– Check all other cylinders for correct ignition. If they are not correct, stop the engine, and
recheck wiring and ignition sequence for correctness.
– Stop the starting process. If no problems occur, start the engine in accordance with the
specifications of the engine manufacturer.
9.2 Shutdown
The ignition controller is shut down by disconnecting it from the power supply.
