PHLOX - Ignition Control System 85
11.3.2 Measuring Method 2 (Software Version AAA-B1/2-DDD)
If the measuring wheel has a single tooth gap, firmware variant B1 must be used.
If the measuring wheel has a double tooth gap, firmware variant B2 must be used.
The pick-up and measuring wheel are set up in exactly the same way in both
cases.
This method makes use of one pick-up and a measuring wheel with tooth gap placed on the cam-
shaft. The setup is very similar to that in measuring method 1 but no cam index is used.
Camshaft pick-up setup
Activate Pick-up:
Par. 4001 = 1 (Pick-up is on camshaft)
Par. 4002 = 1
Configure pick-up type according to used pick-up:
Par. 4020 = 0 for Hall Pick-ups.
Par. 4020 = 1 for inductive (magnetic) pick-up.
Hall camshaft pick-up setup
This paragraph concerns only Hall pick-ups
Configure pick-up power supply according to pick-up specification
Par. 4022 = 0 to setup a 12V pick-up power supply
Par. 4022 = 1 to setup a 5V pick-up power supply
Configure pick-up signal output according to pick-up specification:
Par. 4023 = 0 for Heinzmann standard pick-up signal output (signal low when pick-up
over tooth, high when pick-up over gap)
Par. 4023 = 1 for inverted pick-up signal output (signal high when pick-up over tooth,
low when pick-up over gap)
Configure trigger edge for best timing:
The pick-up used determines whether the rising or falling edge should be used for opti-
mum ignition timing.
Par. 4024 = 0 for Heinzmann standard trigger edge (begin of tooth / gap)
Par. 4024 = 1 for inverted trigger flank (end of tooth / gap)
