7、 switches on the center of the PC board (Figure 3-1) is the order from left to right.The function of the first bit DIP switch: select the starting up delay function. When the first bit DIP switch dial on, the PC board will work as soon as the start-up. (this feature is used at the time of debugging

8、or maintenance of ice-making machine). In contrast, PC-board does not work after the start-up, they have 5-minute delay before the work, which is in order to ensure the machine works after the sensor started to work normal.The function of the second and third bit DIP switch: select the full-ice sens

9、or. Select scale ice machines ice-full sensor when the second bit DIP switch dial ON. In contrast, select flake ice machines ice-full sensor when the third bit DIP switch dial ONThe function of the fourth bit DIP switch: DIP invalid.The function of the fifth bit DIP switch: select the models of the

10、reduce motor. Select the 960RPM model when the fifth bit DIP switch dial ON. In contrast, PC board selects 1440RPM model.( the location of switch has been set up at the factory, the user should not be struck)The function of the sixth bit DIP switch: select the buzzer alarm. when the sixth bit DIP sw

11、itch dial ON, the buzzer will alarm when the faults appeared, in contrast, the buzzer is invalid.The function of the seventh bit DIP switch: DIP invalid.The function of the eighth bit DIP switch: select the test parameter measurement.(test the PC board designed parameters when it was made).( the swi

14、he first bit DIP switch: select the test of motor speed. when DIP switch dial on, if there was speed fault in the course of PC board working, the low-rotating speed fault indicator would on. the PC board would continue to work.( this feature is used at the time of debugging or maintenance of ice-mak

15、ing machine). In contrast, if there was speed fault in the course of PC board working, all the work would stop.The function of the second bit DIP switch: select the test of condensing temperature sensor. when DIP switch dial on, if there was condensing temperature fault in the course of PC board wor

16、king, the condensing temperature fault indicator would on. the PC board would continue to work.( this feature is used at the time of debugging or maintenance of ice-making machine). In contrast, if there was condensing temperature fault in the course of PC board working, the indicator would on and t

17、he compressor would stop immediately and the speed would stop in 3 minutes .The function of the third bit DIP switch: select the test of evaporation temperature sensor. when DIP switch dial on, if there was evaporation temperature fault in the course of PC board working, the evaporation temperature

At this tine, we can adjust the full-ice sensitivity resistor on the PC board to adjust the sensor sensitivity. Clockwise rotate adjustment resistan
