AOUT 1-4
1
A+H
Indication of error in communication with analog outputs
extension module.
Check if the unit with corresponding CAN address is
-
powered up
-
address of the module is set correctly (see
Modules card in GenConfig and an extension
module manual)
-
correctly connected and check connection of
terminating resistors on the CAN1 bus (see IGS-
NT Installation Guide,
External
modules
connection
chapter)
-
the CAN bus Low and High wires are not swapped
To check module communication activity look at the Tx and
Rx LEDs of the CAN bus port. Fast flashing means that
communication is OK.
ECU
1
A+H
Indication of error in communication with ECU.
Check if the ECU is:
-
correctly connected to the CAN1 port of the
controller (see Comap Electronic Engines Support
manual for information about ECU connection)
-
powered up
-
terminating resistors are properly connected
-
the CAN bus Low and High wires are not swapped

module.
Check that
-
one of the controllers on site is configured as a
SOURCE controller (has SHBOUT (x) module
configured)
-
the SOURCE controller is powered up
-
TARGET and SOURCE controllers are connected
to the CAN2 bus and Tx and Rx LEDs of the CAN2
bus ports are flashing
-
the controllers can "see" each other
– check
CAN16/CAN32 values on the Power management
screen (each controller is indicated by 1 on the
position given by its address)
-
CAN2 bus connection is done according to the
IGS-NT-Installation
Guide,
Recommended
CAN/RS485 connection
chapter.
SHAIN 1-4
1
A+H
Indication of error in communication with SHAOUT 1
–4

configured)
-
the SOURCE controller is powered up
-
TARGET and SOURCE controllers are connected
to the CAN2 bus and Tx and Rx LEDs of the CAN2
bus ports are flashing
-
the controllers can "see" each other
– check
CAN16/CAN32 values on the Power management
