Pickup Trace
The traces of the pickup signals support you in checking the behavior of the used pickup and thus, for example, to detect and analyze irregularities or failures.
Pickup signals are automatically recorded by the ignition controller as soon as they are detected at the configured inputs. Ten further signals are recorded if an error occurs during operation (cumulative across all inputs). The recording is then stopped so that the pickup signals just before the error can be analyzed. The records can be downloaded from the device at any time.
Proceed in the MICT as follows:
Device -> Pickup trace

Pickup trace
Example of a pickup trace for a configuration with three pickups:
- Pickup input 1 (cam):
Single event from the camshaft - Pickup input 2 (reset):
Single event from the crankshaft - Pickup input 3 (trigger):
Trigger disc of type N with 160 events from the crankshaft

Operation
The following options are available via the menu in the window:
- Open
Opens a previously saved pickup trace. - Save as
Saves a pickup trace as a .putrace file.
- Close
Closes the pickup trace.
There are the following options for the display of the pickup signals:
- Zoom In/Out
Using the mouse scroll wheel you can zoom in and out of the displayed record range. Alternatively you can also use the plus and minus keys on the keyboard. With the zoom function, you can e.g. analyze the trigger signal more precisely (pickup input 3 in the drawing).
- Move displayed range
With the right mouse button pressed you can move the displayed range along the time axis. - Measuring
You can measure distances and the number of events in the displayed range by holding down the left mouse button to highlight a section. You can find the following information in the window:- Position on the time axis
- Time difference (Δ) between the two selected points
- Number of events counted in the selected period

Error Analysis
The pickup traces support you, for example, in analyzing the following errors:
- Configuration of the pickup does not agree with the wiring (e.g. trigger disc configuration, allocation of the inputs, allocation of the shafts). In this case, you should compare the values configured with the signals recorded (see Engine – Pickups).
- One or more pickups have failed.

Pickup trace
The pickup signals are only recorded on the inputs that are configured in the MICT. If the configuration of the pickup inputs is not valid (e.g. three signals from the same shaft), no signals are recorded.
