COSMOS DRIVER SERIES 3000 - USE AND MAINTENANCE MANUAL
EXAMPLE 1:
COSMOS 1
COSMOS 2
COSMOS 3
COSMOS 4
ERROR 29 or 30
ERROR 29 or 30
ERROR 32
ERROR 32
The problem occurs between
COSMOS 2 and COSMOS 3. The control unit is working properly. It is recommended to
proceed as follows:
1. Check the optical fiber section between the TX of
COSMOS 2 and the RX of COSMOS 3: if possible, check the
attenuation applied, reduce too narrow bend radii or replace the optical fiber, if it is damaged.
2. Extract the fiber from the TX of
COSMOS 2 and make sure that the transmitter emits light; otherwise, the driver
is damaged and needs to be replaced.
3. If the above problems do not exist, replace the
COSMOS 3.
This example is valid for an arbitrary number of devices and for all sections of optical fiber.
EXAMPLE 2:
COSMOS 1
COSMOS 2
COSMOS 3
COSMOS 4
ERROR 32
ERROR 32
ERROR 32
ERROR 32
The problem occurs between the control unit and the first device in the ring
. It is recommended to proceed in the same
way as indicated in the previous example.
EXAMPLE 3:
COSMOS 1
COSMOS 2
COSMOS 3
COSMOS 4
ERROR 29 or 30
ERROR 29 or 30
ERROR 29 or 30
ERROR 29 or 30
The problem occurs between the last device in the ring and the control unit. Refer to example 1 in order to find the fault.
EXAMPLE 4:
COSMOS 1
COSMOS 2
COSMOS 3
COSMOS 4
ERROR 22
ERROR 21
ERROR 22
ERROR 22
The address or the setting of the active controller in the
COSMOS 2 is not correct. Follow the procedure indicated in
The above instructions should not be regarded as an infallible guide. The combinations of the error
codes and the problems causing the errors depend on several conditions inherent in a complex
communication system such as the SERCOS.
