SDCS-IOB-3 3BSE004086R1

SDCS-IOB-3 (analogue I/O connection board) LED’s on the SDCS-IOB-3 board shows the following: - V17 is lit when the encoder supply is OK - V17 is blinking if a short circuit has occurred between X5:7 - X5:8 - if the auxiliary voltage of encoder is 5 V it is possible that the V17 is lit though there is a short circuit somewhere in the cable of the encoder (according to the impedance of cable).
Other fault conditions and repair Main fuses are blown In case of burned main fuses there is a high possibility of short circuit in the main circuit SDCS-PIN-XX (bridge). Measure the main circuit to find out the fault source. Never change the fuses without measuring the condition of main circuit! Main fuses can be changed as well as measurements of the semiconductors can be done when the converter is disconnected from the AC-supply by means of the fuse disconnector Q01 and the zero voltage is measured with a voltage meter between L1 - L2, L1-L3, L2-L3, L1 - PE, L2 - PE and L3 - PE. Check the connection from delivery documents. General instruction how to replace boards The main voltage must be disconnected when replacing circuit boards. Remove all ribbon cables and/or screw terminal blocks from board. Remove all screws holding the board. Compare that new and old boards have the same type designation or that the new board can replace the old one. Check the jumper settings, components on solder posts and scaling (or burden) resistors of the old board and ensure that the jumpers, components on solder posts and scaling (or burden) resistors are set in the same way on the new board. How to replace the SDCS-CON-1 board Ensure that the spare board is compatible with the old board and take care that the parameters will be correct after replacing. If the program version of new board is the same as the old version then the possibilities to load parameters are: - Change the FLASH-memory D35 from the old board to the new board. Note! Install the circuit to the correct position into the board using suitable tool. - Download the parameters. If the program version of the new board is different than the old version it must be checked that those versions are compatible. If the program version (circuits D33 and D34) will be changed from a old board to the new board it must be checked that the hardware of new board is compatible with the new program version. In indistinct cases contact to the nearest ABB Service representative. ULMA DCS500 parameter load to DCS500 flash memory - switch power OFF from DCS cabinet - change the jumper S2 to position 1-2 - switch power ON (now the DCS500 reads initial values from EPROM to battery back-up RAM memory)
