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.
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.
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: 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.
053 Link fault between smart relay and bus-type extension
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).
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.
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.
060 At the beginning of RUN on the smart relay application: Program incompatible with the bus
extension physically connected to the power supply.
If this problem occurs, contact the after-sales service.
