DESCRIPTION OF THE GIS IGNITION SYSTEM
4/7
1.1. GIS IGNITION MODULE
1.1.1. General
features
The main features of the GIS ignition module are as follows:
-
Microprocessor-based digital system with highly precise distribution of engine ignition, based on
crankshaft and camshaft position reference signals.
-
Optional programming adjustment to adapt to different engine configurations.
-
Optional manual timing adjustment can be configured according to engine speed, analogue signals,
potentiometer, digital inputs and/or communications.
-
Option to adjust timing per cylinder.
-
Option to adjust ignition energy and even configure different energy levels for start-up and normal engine
operation.
-
High capacity for diagnosis in the primary and secondary ignition system circuits.
-
Modbus RTU and CAN 2.0b (CANopen) communications.
-
Ability to generate a series of pulses that control other equipment, such as the Detcon, injection system,
etc.
-
USB connection compatible with USB 1.1 and USB 2.0 for connection to PC.
-
CE
Marking.
-
Certification CSA Class I, Division 2, Group C, D; T4.
All the system options are selected by
Kohler
on the basis of the requirements and characteristics of each
application. All the data required, such as distribution of ignition, configuration of the energy parameters,
ignition sequence, number of flywheel teeth, etc. are programmed at the factory.
NOTE
Refer to IT-G-A-33-011 for programming the GIS ignition module. Refer to IO-G-M-33-010 for information on the
display module. Refer to IM-G-C-33-006 for installation of the ignition module.
1.1.2. Functions and operation
Configuration of pickup signals
Unlike the CPU 95 module, the GIS ignition system can operate with different pickup signal configurations,
making it a more flexible system. With
Kohler
engines, it can operate with two different configurations:
-
2 PU configuration: The ignition module operates according to the signals received from the magnetic
tooth pickup and the camshaft Hall effect pickup.
-
3 PU configuration: The ignition module operates according to the signals received from two magnetic
pickups fitted to the crankshaft (teeth and reset) and the camshaft Hall effect pickup.
Analogue/Digital Inputs
The ignition module has an analogue input which, once configured, allows the advance ignition to be adjusted.
The analogue signal can be intensity (4-20 mA) or voltage (0-10 V). With
Kohler
engines, this analogue input is
connected to the Detcon and configured so that the ignition unit reduces the advance as the mA of the signal
increase.
