Touch Screen Interfaces and Functions

◆ User Setting Interface–Primary Level Menu

By operating the touch screen interface, the user is able to make product, clean the machine,

adjust viscosity, reset counters, etc. The main screen

also monitors and displays operating status, hopper and cylinder temperature readings,

product-making progress, among other information.

13

1. Auto --After pressing Auto

The machine will run freezing cycle as programmed.

The cycle will stop when desired levels of product temperature and/or viscosity are

met; after a certain period when product temperature rises to a preset level,freezing

cycle will resume.

Product-making icon shows the progress and process movement.

14

2. Hopper Refrigeration

When it is pressed, hopper refrigeration process starts. Otherwise,

when freezing cycle starts, hopper refrig-eration also starts; when

freezing cycle stops, hopper refrigeration also stops.

15

3.Clean

When pressing Clean, machine will start cleaning itself. Make sure to ll the beater cylinders with water. Beater motors start to run and the machine enters the clean mode. Clean page will be displayed on the screen.

(If machine has air pumps, the pump will run together)

16

4. Sleep--When Sleep is pressed,

The machine enters night-time sleep mode, which maintain product

freshness and prevent bacteria from growing.

5. User Setting Interface--Secondary Level Menu

5. Touch-screen Functions

Discharge Door Alarm

The icon warns of improper installation of

the discharge door assembly. For safety,

the machine will stop running immediately.

Overtime Alarm

During freezing cycle and sleep mode, the

icon warns that the machine has been run

-ning for beyond present time period and s

ystem will shut off compressor to prevent

over-freeze.。

Beater Motor Alarm

During freezing cycle and sleep mode, the

icon warns of motor non-start or over-load

and system shuts off beater motor.

High Pressure Alarm The icon warns of overly high pressure in the refrigeration system and system shuts off compressor immediately.

Low Temperature Alarm

During freezing cycle and sleep mode,

The icon warns of excessively low tem

-perature in the beater cylinder and

system shuts off compressor to prevent

over-freeze.

Mix Low Alarm

The icon warns of low mix level in the

hopper. If low mix protection is activa

-ted, system will shut off compressor to prevent over-freeze.
