Schmelz-Kontrolleinheit.

摘要

A fusion control unit having a casing (10) with a panel (11) through which information can be communicated optically. Infra-red transmitter (24) transmits information from a microprocessor (29) within the fusion control unit to an external optical communication box (30) and infra-red receiver (25) receives information from the external optical communication box to transmit to the microprocessor (29). The fusion control unit can thus communicate with an external computer, for example, without compromising the integrity of the unit.
