6) Output Short Circuit Protection (Status Input Bits)
Status Input Bits report the integrity of the load being driven by the output driver. They must be mapped to the
scanner as part of the Input Size Value. Please refer to the table below for Status Input Bit action during fault
condition:
Output Type
Valve Solenoid Coil Driver or
Sinking (NPN)

7) Ground Wiring

All Numatics Inc. communication nodes should be grounded during the installation process. These
grounding guidelines can be found in National Electrical code IEC 60204-1 or EN 60204-1. There also is a,
"ATTENTION: CONNECT TO EARTH GROUND FOR PROPER GROUNDING OF UNIT", label
attached to the chassis ground connection point on the G2-2 series communication node housing. This label
also points out where the grounding guidelines can be found.

Proper grounding will alleviate and prevent many intermittent problems
with network communication.
When grounding to a machine frame, please ensure that the machine frame
itself is already properly grounded.
Better grounding can be achieved when larger diameter (lower gauge) wire
is used.
