Possible cause
The electronics supply voltage is
less than the lower tolerance limit
(18 V DC) and greater than
10 V DC.
The electronics supply voltage
is less than 10 V DC.
The electronics supply voltage
is significantly less than 10 V DC.
The actuator voltage is less than
the lower tolerance limit
(21.6 V DC) and greater than
UA-OFF.
The actuator voltage is less than
UA-OFF.
Invalid address (address = 0 is not
permitted)/Address = 2 is set
automatically the bus coupler
Diagnostic message from module
present
There is no module connected
to the bus coupler.
There is no end plate present.
More than 32 electrical
components are connected on the
valve side (see section 12.5.3
"Impermissible configurations"
on page 118).
Over ten modules are connected
in the I/O zone.
The module circuit boards are not
plugged together correctly.
A module circuit board is defective. Exchange the defective module.
The bus coupler is defective.
The new module is not recognized. Contact AVENTICS GmbH
Module is in the BUS OFF state
(not active in CANopen bus).
Module is in the ERROR PASSIVE
state (at least one error counter
has reached or exceeded the
maximum value)

Troubleshooting
Remedy
Check the power supply at plug
X1S.
Set correct address (see "9.2
Setting the address on the bus
coupler" on page 99)
Check modules.
Connect a module.
Connect an end plate.
Reduce the number of electrical
components on the valve side
to 32.
Reduce the number of modules
in the I/O zone to ten.
Check the plug contacts
of all modules (I/O modules,
bus coupler, valve drivers,
and end plates).
Exchange the bus coupler
(see back cover for address)
Check CANopen communication
(other participants, baud rate,
termination resistance, bus
connections, etc.)
