tAS Keypad test
The keypad test program is used to check the operation of all the keys on the control panel. Every time a button is pressed the code
of that key will appear on the display: for example, by pressing [P8] key Start the code “P8” will be viewed, by pressing
[P10] key Stop the code “P10” will be viewed and so on. The code of the key [P7] is not displayed.
To exit the test program, press [F+P9] keys .
UFc Converter voltage – frequency test
Il The converter voltage – frequency test shoes two numbers on the displays that represent the values of the internal conversion to
the electronic control circuit board.
These values are used by technical support personnel to determine the functioning status of the circuit board.
To exit the test program, press [F+P9] keys .
SMo Shaft smoothness test
This program allows you to measure the smoothness of the shaft.
These values are used by technical support personnel to determine the functioning status of the machine.
To measure the smoothness of the shaft proceed as follows:
1. Remove the wheel and any other accessory from the shaft. This is very important because otherwise the value measured
will be completely meaningless;
2. Press [P8] key Start or lower the guard (when present): the machine will perform a sequence of brief motor
ignitions, each time letting the shaft run out of rotations for inertia;
3. Upon completion of the sequence the machine displays the value of the smoothness measured. The smoothness value is
not absolute but refers to a sample machine whose smoothness value has been set at 1.00. The value measured is stored
in the permanent memory of the machine in order to be used in the functions that are connected to the smoothness of the
shaft. To exit the test program, press [F+P9] keys .
Ret Returns to the SERVICE mode
This Test Program menu option sets the machine back to the SERVICE mode.
20. SIGNALS
When abnormal operating conditions occur the machine emits two types of signal:
•
Error
• Warning
•
The Error signal is always accompanied by a triple beep indicating that the machine cannot run the command given by the
operator, or, during operation, conditions were encountered that prevent the action in progress from continuing.
•
The warning signal is always accompanied by a double beep that prompts the operator to perform a particular action, or it
refers to the fact that the machine has changed status. In any case, the requested operation is not prevented or the current
function is completed.
