Thyro-A has been conceived to meet the demands for simple assembly, speedier
commissioning and safer operation.
For transport, assembly, installation, commissioning, operation and decommissio-
ning, it is essential that the safety instructions included in these operating instructions
are observed and made available to all persons handling this product.
In case of uncertainties or missing information, please contact your supplier.
The described operating mode QTM is in preparation.
Thyro-A is a Thyristor Power Controller with the ability to communicate. It will also
simply be referred to as Power Controller or Controller. It can be used wherever vol-
tages or currents need to be controlled or regulated in processing technology.
Thyro-A's distinguishing features are its several operating and control modes, good
coupling ability to process and automation technology, high control precision and
simple handling through a 16-Bit processor.
1.2 Specific characteristics
