Sample Application
A manufacturing engineer is designing a test chamber that must be very
simple for the operator to use. He would like to start the program with
minimal operator interaction.
By connecting an external switch to the digital event input, he can config-
ure the Series 982 to start the program in File 1, when the switch momen-
tarily closes. Enable this function by selecting File 1 [FIL1] for Event
Input 1 [`Ei1] (Global Menu). Once the program is started, closing this
switch will not have any effect until the program has finished or the pro-
gram is terminated.
The operator must also have the ability to pause a running program and
then resume it again with the same simple interaction.
By ordering the optional second digital event input, another switch can be
used to pause the program when the switch is closed and resume running
the program when the switch is opened again. Enable this function by
selecting pause [PAUS] for Event input 2 [`Ei2] (Global Menu). This func-
tion is only active once a program has been started.
The operator now has the ability to start a program with the press of a
button, and pause or resume it with the flip of a switch. The operator
never needs to touch the Series 982.
