Rev. 03/2019 59
The ignition controllers of the MIC5 series include freely configurable safety and auxiliary
functions that, amongst others, can shut down the engine in case of fault.
Angle indications in the operating manual
All angles in this operating manual are given in °crankshaft. Exceptions are
clearly identified.
7.1 Pickup Sensitivity
To increase the signal interference distance, the sensitivity of the pickup signal inputs can be
changed for suitable pickup signals. This setting can be implemented individually for each
input. For this purpose, a pre-trigger voltage can be set below which signals are interpreted as
interference and are therefore not analyzed. A pre-trigger voltage set to a high level will thus
result in a low pickup sensitivity level.
You can enter the settings for the pickup sensitivity with the MICT. Refer to the section Engine –
Pickups on page 96.
7.2 Monitoring of Pickup Signals
The MIC5 monitors the pickup signals. Any other errors are displayed in the MICT. For more
information on the errors, please refer to the overview in the section entitled Pickup Input Errors
on page 164.
7.3 Go/NoGo
The binary output (Go/NoGo) is a potential-free output. It is closed during firing and opens when
the ignition switches off. The max. switching current is 100 mA. The output can drive an external
relay that e.g. opens a gas valve.
The following errors can cause the ignition outputs to shut down:
– Overspeed
– Pickup error
– Error HV power supply
– Failure of the output monitoring
– Overload/temperature shut-down
– Alarms
– Insufficient supply voltage (Low Power)
