8.6.3 Digital
Inputs
The EZT-570S digital input option provides eight digital inputs which can be used to start and stop an
automatic ramp/soak program, hold a program or control optional event outputs. If your chamber is
equipped with the digital input option, this menu item will appear in the Hardware menu. With this
option, electrical connections are provided on the chamber for external connection to each input.
The digital inputs can be configured to work on either a low to high transition or a high to low
transition. Upon seeing the selected transition, the input will perform the action selected from the
input function list. To configure a digital input, select “Digital Inputs” from the Hardware menu.

The left and right navigation buttons at the upper right of the screen allow the user to scroll through
each available input. To make changes to the input’s configuration, select the desired transition
mode and function for the input. Once all selections have been made, press the ‘Save’ button to save
the changes. If you do not press the ‘Save’ button, all changes will be lost if you leave the screen or
navigate to another digital input.
More than one digital input can be configured for the same function. If more than one is set
for the same function, make sure that they do not interfere with each other or the selected
function they are to perform may not operate correctly.
The
Transition
select buttons set the input state that makes the input perform the required function.
High:
This setting sets the input up to perform the desired function when the input goes from an
off state to an on state. This requires the application of 24Vdc power to the input.
Low:
This setting sets the input up to perform the desired function when the input goes from an
on state to an off state. That requires the removal of 24Vdc power from the input.
The digital input
Function
defines what event is to happen when the input meets the transition state.
The input Function list is shown when the function selection button is pressed. The input functions
selections are mutually exclusive, i.e., only one can be on at a time. An input can be disabled by
selecting “Inactive” from the function list. Once the desired selection has been made, press the
‘Return’ Button to return to the Digital Input screen.
