This chapter shows the operating options of Thyro-P using LBA and Thyro-Tool Familiy.
3.1 LOCAL OPERATING AND DISPLAY UNIT (LBA)
The optional LBA (IP30, protection classifi cation 3) has fi ve keys and a backlit graphical LC display
for 7 x 19 characters respectively 64 x 114 pixels. In the standard version, the languages German,
English and French are available.
The LBA may be connected or disconnected from the RS 232 interface of the Thyro-P control device
during operation. After plugging into the interface and automatic loading of the parameters, the
LBA displays its main menu.
ATTENTION
Before storing (store in Thyro-P / LBA under Thyro-P) the parameters must always be saved in the
EEPROM of the LBA fi rst (store in LBA).
If no key is pressed for one minute the operation display appears. This does not apply if a line
diagram is running. If no communication is achieved after plugging in the LBA between LBA and
Power Controller in case of fault, then a self-test is performed. Using the LBA, Thyro-P may be
parameterized and monitored under menu control. It is possible to display up to three process
data values (for instance the actual values of current, voltage or power occurring at the load) in
double character height. Further values which may be displayed are the set point value as well as
parameter data and fault indications. Furthermore, display of a value in graphical form as line dia-
gram is possible. The time and value axes may be set by parameters and so adjusted to require-
ments. Using the LBA, the parameters of one Thyro-P may be copied to another Thyro-P. More
details on this can be found in the chapter LBA menus.
3.1.1 LBA KEYBOARD FUNCTIONS
The LBA has a total of 5 standard keys: with an activatable parameterizing lock (see table 5). Four
arrow keys and one OK key. By moving the cursor mark (>) using the corresponding keys (up arrow,
down arrow), the desired function may then be selected using the OK key. An underlined language/
function is in each case selected. An unnamed 6th key is available behind the opening in the front
of the LBA, the reset key. If this is operated, then the functions RESET of Thyro-P is performed.
