Ⅲ．DIP switch

1. 8-bit DIP switch (Attention: Please press reset button before resetting DIP switch.)

Select flake ice machine ’s ice-full sensor.

Select scale ice machine ’s ice-full sensor.

Figure 3-1

Eight-bit DIP 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 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 sensor. Select scale ice machine ’s ice-full sensor when the second bit DIP switch dial ON. In contrast, select flake ice machine ’s ice-full sensor when the third bit DIP switch dial ON

The function of the fourth bit DIP switch: DIP invalid.

The function of the fifth bit DIP switch: select the models of the 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)

open starting up delay function

cancel the buzzer cancel starting up delay function

open the buzzer select 1440RPM model

cancel the test parametermeasures select 960RPM model

open the test parameter measures
