. 1 is only a guide showing installation of the Gate-
way Assembly in a ProMix 2KS System; it is not a com-
plete system design. Contact your Graco distributor for
assistance in designing a system to suit your particular
needs. This procedure is an example of how to connect
the Gateway Assembly to a Graco EasyKey, though it
may also apply to other Graco System Controllers.
1. Shut off power at the main circuit breaker
2. Shut off ProMix 2KS power (0 position). See F
IG
. 2.
3. Turn off power to the Graco EasyKey and the
Gateway Assembly before connecting or
disconnecting communication cables.
NOTE: For specific system communication circuit
connections and register mapping details, refer to the
following product family manuals: ProMix 2KS (312779),
ProControl 1KE (3A6948 and 332013), Graco ACS
Module (3A0006), and Graco ProDispense (3A3469).
4. Connect a 2-wire twisted pair cable (provided with
assemblies 25B471-25B473), see F
IG
. 5, with shield
wire from the EasyKey connector to the connector
on the Gateway Module.
5. Connect a communications wire/cable (protocol
dependent) from the Gateway Module to the PLC.
(See
Communication Connections , page 11.)
NOTE: Graco provides expansion cards for DeviceNet
and Profibus protocols. DeviceNet setup procedures are
on page 32. Profibus setup procedures are on page 35.
See
Parts , page 26, for part numbers.
NOTE: When using the Gateway Assembly in your sys-
tem, disconnect both communication cables (one to the
Graco System Controller and the other to the PC or
PLC) before updating the system software.
Grounding
Gateway Assembly
Grounding is provided by both a proper power connec-
tion and a grounding screw on the enclosure.
• For a proper power connection, see Power
Connections , page 9, and Electrical Schematics ,
page 16, for details and grounding locations.
• For the enclosure grounding screw (4), use a
ground wire (35) and clamp (supplied). Remove the
grounding screw (4). Attach the ground wire (35)
end, as shown, and tighten the ground screw (4)
securely. Connect the ground clamp to a true earth
ground.

The equipment must be grounded to reduce the risk
of static sparking and electric shock. Electric or static
sparking can cause fumes to ignite or explode.
Improper grounding can cause electric shock.
Grounding provides an escape wire for the electric
current.
