2.6 LC100-SR safety circuit board
LC100-SR safety board is used to connect elements of a safety circuit. Information about points of safety circuit is
transfered to lower voltage through optocoupler and then transfered through XS3 flat connector to main LC100-C
board.
Elements of a safety circuit are connected to connectors XS1 to XS2 which are red coloured.
On the board there is a safety fuse and status LED diodes.
There is two versions of LC100-SR board acording to the safety circuit voltage:
3. 220VAC and 48VAC (with capacitors)
4. 48VDC (short circued capacitors).
