7. Deciphering EZT Input/Output (I/O) Operation
The inputs and outputs of the EZT-570i are predefined for specific functions on all standard chamber
designs. This requires that certain inputs and outputs perform different functions based on the
chamber type. This section covers all of the standard inputs and outputs of the system and their use
based on the chamber type. For each input and output, an individual functional description is
provided on how the input or output is used.
The control of the EZT outputs are also defined by which chamber events are enabled. The chamber
events are predefined and their use varies according to the type of chamber and options present.
The following table defines the standard use of the events.
