Switching Setting Groups
You can program a total of sixteen Group Logic statements per setting group
to cause a setting change from one group to another. Create settings using the
Offliner setting software or by using the Terminal Mode.
An example of pulsing an external input and an example of a solid initiate to
activate setting group changes are shown below.
Using One External
Input to Toggle
Setting Group
Use one external input connected to a SCADA output contact to toggle be-
tween two or more setting groups. In this example we connect external input
one (EI 1) to the SCADA control output contact and switch between group one
and group two. If you wanted to switch through all setting groups, group logic
two would switch to setting group three, and so forth. If the contact input to
switch setting groups becomes welded shut or the SCADA system has a prob-
lem, the relay will only switch to the new logic and stay in that logic until the
input has been de-energized for the ProLogic pickup delay, which was set to
10 seconds.
Setting Group 1 – Logic Statements
When setting group one becomes active either through a setting group change
or is the default group after relay power up, ProLogic 9 becomes high after the
10.00 second delay, if EI 1 is low. ProLogic 9 is set for a 0.26 second dropout
time; to be used with ProLogic 10 dropout timer allowing for the slower pro-
cessing thread where Group Logic is processed and providing a definite timed
pulse to the group logic.
