The voltage supply is rectified and stabiliseddirectly by the board.This board houses the Flash EPROM. The control soft-ware of the board is installed directly (via RS232 or UpKey)in the microprocessor.- the red LED (7) indicates the operating status of the boilerheating element;- the red LED (9) for resetting the CPU glows during theboard reset;- the green LED (11) blinking indicates that the microproc-essor is working correctly;- the yellow LED (12) indicates the presence of 5 V DC.YALER WERBHSERF1K MP2K DESUTON3K 1FM4K DESUTON5K 4VE6K 3VE7K DESUTON8K DESUTON9K BFVE01K 1DM11K 2VE21K DESUTON31K DESUTON41K AEE51K DESUTON61K 2DM-CAMFig. 261 - Main switch2 - Mains fuse3 - Boiler control board4 - Brewer control board5 - Actuation/CPU board6 - Transformer fuses7 - TransformerFig. 271 - 120 V~ users2 - Input signal3 - Can-Bus connection4 - Can-Bus connection5 - Relay expansion connection6 - Boiler control probe7 - Red LED - boiler heating element8 - Input signal9 - Red LED10 - Not used11 - Green LED12 - Yellow LED13 - To the push-button board14 - Connector for board programming (RS232)15 - UpKey connector16 - Board power supply (15Vac)17 - Relays K1÷K1618 - 120 V~ users
