CAUTION:
This function must be used with extreme care. It is possible to force safety related input,
or outputs, such as an interlock, thereby disabling them.
Digital Inputs Setup
This screen allows you to change the mapping and properties for the digital inputs. A
Logical Input is always mapped to a Physical.
NOTE
Always On
and
Always Off
are valid physical inputs. You can’t invert or force them,
however.
Select Column
This button switches the active scroll area between the Logical and
Physical sections. First select the logical input you want to work with,
using the Up and Down arrow buttons. Then push the Select Column
button to map it to a physical input, again using the Up and Down
arrow buttons.
Invert Off/On
This button inverts the logic of the Physical input. For example, if the
Fill Gt Closed
logical input is mapped to a physical input that is Off
when the gate is closed, you would have to invert that input. An
inverted input will have a
1
in the
IV
column. The button is only
available when you have the Physical Input column selected, since
the Invert property is associated with the physical input.
Force None/Off/On
This button toggles the
FC
indication through Forced On
1
, Forced
Off
0
or no Force
-
. There will be a blinking indication on the Main
Screen if forces are present. The button is only available when you
have the Physical Input column selected, since the Force property is
associated with the physical input.
Alarm None/Warning/Fault
This button cycles the
FW
column between Fault (
F
),
Warning (
W
) and None (
-
). If a logical input with Faul” property is
turned on, the feeder will stop. See Warnings (page 14) and Faults
(page 15). The button is only available when you have the Logical
Input selected, since the Fault and Warning properties are associated
with the logical input.
Accept
When you are done with your Logical Inputs configuration, push this
button to make your configuration changes permanent. The button is
only available when you have the Logical Input selected.
Esc
Takes you back to the Inputs and Outputs Setup Screen. If you push
this button without first pushing the
Accept
button, The Digital Inputs
configuration will be restored to the condition it had when you entered
this menu.
