Bay Name
There are 20 characters available for the bay name, so use descriptive names
such as OCEANVIEW FEEDER. This name appears on all the control
screens to identify the feeder bay, thus avoiding confusion during operation.
Local
The LOCAL SELOGIC control equation manages local and remote control of
the disconnect switch. This example illustrates how the relay input contact
IN207 can accommodate existing bay controls that use a key to manually
change from remote to local control. The key switch is made to actuate a
contact when the key is turned, as shown in Figure 12.19. With the contact of
the switch wired to the relay input, the key switch provides local and remote
control. Make the following setting to enable LOCAL control when IN207 is
asserted.
LOCAL := IN207
