6.27 Relay (1-8) Output Menus – Feed After Another Relay (Fixed Time)
This page is used to program to activate one relay after another relay has been activated. The first
relay will activate. When the first relay shuts off the second relay will activate for a programmable
amount of time. If you make changes to the Input Assignment, you will need to click on the
"Submit" button in order to see all the correct units.
You may also change the Relay Control Mode here. If you do, you will have to reselect the Input
Assignment as well.
This section assumes that the Relay Control Mode is set to Feed After Another Relay (Fixed
Time). Other control mode types are described in other sections of the manual.
