Schneider Electric SR2MAN01 Fault Types, Clock write fault, Overload on solid state relay outputs

DEFAULT Menu

Fault Types Below, the description of possible faults:

Number Type of fault

000 No faults

001Fault 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.

002Clock write fault

If the fault occurs frequently, contact the after-sales service.

004Overload 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).

050Smart relay firmware is damaged

Reload the firmware on the smart relay and the user application. If this problem persists, contact the after- sales service.

051Watchdog 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.

052The 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.

053Link fault between smart relay and bus-type extension

Check operation of the extension (connection, power supply, fault).

054Link fault between smart relay and input/output-type extension

Check operation of the extension (connection, power supply and fault).

058A 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.

059At 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.

060At 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.
