Fault Types
Below, the description of possible faults:
Number Type of fault
000
No faults
001
Fault in writing to EEPROM
This fault defines the transfer problems between the memory cartridge and the smart relay. If this fault
occurs frequently, contact the after-sales service.

002
Clock write fault
If the fault occurs frequently, contact the after-sales service.
If the fault occurs frequently, contact the after-sales service.
004
Overload on solid state relay outputs
Once a transistor output reaches a temperature of 170°C, the group of 4 outputs to which it belongs is deactivated.
To make this group of outputs operational, the cause of the over current (short-circuit, etc.) must first be
deleted, and then the fault cleared from the FAULT menu (see FAULT Menu, p. 77).

050
Smart relay firmware is damaged
Reload the firmware on the smart relay and the user application. If this problem persists, contact the after-
sales service.
Reload the firmware on the smart relay and the user application. If this problem persists, contact the after-
sales service.
051
Watchdog overflow
Warning or error according to the selection made in the menu (smart relay display) or in the configuration
window (programming software).
The cycle time in the smart relay is too short compared with the application program execution time
programmed in the smart relay.
If the application requires cycle time or strict sampling of the smart relay inputs/outputs, lengthen the
application cycle time in the smart relay. To do this, either set the parameters in the CONFIGURATION
menu (smart relay display) or in the configuration window (programming software).
If the application does not require the cycle time, you must choose:
Warning or error according to the selection made in the menu (smart relay display) or in the configuration
window (programming software).

No WATCHDOG Action, in the
CONFIGURATION menu.
052
The smart relay has executed an unknown operation
If the fault is permanent , reload the firmware on the smart relay and the user application. If this problem
persists, contact the after-sales service.
If the fault is permanent , reload the firmware on the smart relay and the user application. If this problem
persists, contact the after-sales service.
053
Link fault between smart relay and bus-type extension
Check operation of the extension (connection, power supply, fault).
Check operation of the extension (connection, power supply, fault).
054
Link fault between smart relay and input/output-type extension
Check operation of the extension (connection, power supply and fault).
Check operation of the extension (connection, power supply and fault).
058
A fault has been detected in the firmware (software specific to the smart relay) or on the smart relay hardware.
If the fault is permanent, reload the firmware on the smart relay and the user program. If this problem
persists, contact the after-sales service.
If the fault is permanent, reload the firmware on the smart relay and the user program. If this problem
persists, contact the after-sales service.
059
At the beginning of RUN on the smart relay application: The application cannot switch to RUN
because it is incompatible with the smart relay physically connected to the power supply.
If this problem occurs, contact the after-sales service.
