Also by using the mould data copy function in block form from standard mould data, saves on setting times. (18) Both the mold data and quality data can be captured by any IBM comptabile PC via a serial communication port with additional software running in Windows 95 system. All this data can be stored on harddisk and printed out by a windows supporting printer.
3.3 Introduction to the computer panel
3.3.1 The Computer Panel Layout
Moulding control parameter keyboard This keyboard has the following functions: (1) Entering the required numerical data for the moulding conditions Speed setting 00-99, 00 means no speed Pressure setting 00-99, 00 means no pressure Position setting 0000-999.9 mm Time setting 0-6553.5 sec Counter setting 0- Mould thickness setting 0-6553.5 mm (2) Checking if the keyboard is operating normally (3) Accessing out the computer control program (4) Checking the operating status of outputs, inputs and timers.
3.3.4 Manual Control Keyboard
(1) The manual operation keyboard can be used to operate the individual movements of the moulding cycle. (2) Mould height adjustment and automatic door operation use the same key as the mould height adjustment function. The screen display must be mould height adjustment.
3.3.5 Power Switch
(1) Emergency Stop Button The red button at the lower right hand corner of the computer panel is used to cut off the electrical supply when it is pressed. Before restarting the machine, turn the red button according to the direction of arrows to unlock the button. (2) Power ON Push Button The green Power ON Push Button is located below the red Emergency Stop Button on the computer panel. When it is pressed, the power supply control unit of this machine will be turned on. This function will protect the computer system effectively, when power is suddenly turned off. (3) The computer includes a voltage stabilizer unit for power input. This will maintain its normal function if the power input varies within the range of AC 90V-AC 265V 50/60 Hz. 3.4 Operation Screen
