Installation Instructions

Part No. 24-10404-9, Rev. D

Issued November 2, 2011

Supersedes April 29, 2011

Applications

The E-Link Gateway provides Johnson Controls® and
YORK® mechanical equipment, such as chillers and
rooftop units, with Building Automation System (BAS)
networking connectivity. It is designed with three active
serial ports: Port 1 and Port 4 are used for BAS
networking, Port 2 is reserved for connecting to the
equipment, and Port 3 provides access for auxiliary
monitoring and control.

To simplify the installation and setup, the E-Link
Gateway comes pre-configured with a series of chiller
and rooftop equipment profiles that you can choose by
selecting the correct DIP switch settings.

Several E-Link Gateway models are available for
connection to various types of input voltage and
equipment. For chillers using the OptiView™ or
Latitude Micro Panel, the E-Link Gateway consist s of a
single circuit board attached to four studs inside the
Micro Panel, using the accessory mounting kit. The
panel supplies 12 VDC input power, eliminating the
need for an external power supply.

For chillers using the IPU-II based Micro Panel, the
E-Link Gateway is installed inside the Micro Panel and
requires an additional transformer to supply power to
the E-Link Gateway. The transformer is included in the
E-Link IPU-II Installation Kit. (This kit is not available in
Europe. Use E-Link Gateway YK-ELNKE00-0.)

For other types of chillers, the E-Link Gateway is
packaged in its own enclosure. In addition to the E-Link
Gateway circuit board, a transformer is included inside
the enclosure that converts a 120- or 240-volt input to
24 VAC power.

Figure 4: Mounting on the Equipment

For all other applications, the E-Link Gateway includes
an optional enclosure. The optional enclosure does not
include communication cables due to the variety of
types and lengths that may be required.

3. Locate and remove the two plastic caps in the
bottom of the E-Link Gateway enclosure.

4. Mark an appropriate place on the enclosure for a
matching set of knock out holes. Mark and drill, or
punch, two holes in the Micro Panel.

IMPORTANT: Never install the E-Link Gateway
outside the confines of a building unless within
another enclosure rated IP 65/NEMA 4x or higher.

The E-Link Gateway can be mounted as a stand-alone
enclosure either on the outside surface of the chiller
Micro Panel (close coupled), or on a smooth surface
within close proximity of the chiller panel enclosure.

For mounting on a Micro Panel, the line voltage power
is supplied by a power source in the Micro Panel.

IMPORTANT: Make sure that the cover is securely
fastened to the enclosure and the internal ground
wire is attached before placing the Gateway in
operation. These steps help to minimize Radio
Frequency Interference (RFI) from being generated
and picked up.

Mounting on a Micro Panel

WARNING: Risk of Electric Shock.

Disconnect or isolate all power supplies
before making electrical connections.
More than one disconnect or isolation
may be required to completely
de-energize equipment. Contact with
components carrying hazardous voltage
can cause electric shock and may result
in severe personal injury or death.

5. Using two bulkhead pipe couplers, attach the
E-Link Gateway enclosure to the Micro Panel.

6. Complete wiring as described in the Applying
Power section in this document.

IMPORTANT: Be careful not to damage the E-link
Gateway or Micro Panel’s circuit boards during the
installation. Protect all circuit boards from metal
chips, which may cause short circuits if left on the
boards at startup.

Note: Use of bulkhead pipe couplers provides
sufficient clearance to allow removal of the E-Link
Gateway cover.

IMPORTANT: When attaching the E-Link Gateway
to a Micro Panel, ensure the E-Link Gateway does
not impede access to other components.

To mount the E-Link Gateway on a Micro Panel:

1. Disconnect power to the chiller Micro Panel.

2. Make sure the E-link Gateway enclosure fits
properly and that no obstructions, such as internal
boards, switches, or external conduit, prevent
mounting or servicing of the panel. See Figure 4 for
examples of good mounting locations.

To mount the E-Link Gateway on a wall:

IMPORTANT: When wall mounting, make sure
there is no interference with other components in the
near vicinity. Use appropriate conduit to connect the
power and communications wiring.

1. Check for proper clearances for the necessary
electrical and communications cable runs.

2. Ensure that power and communications wiring is in
compliance with all local, national, and regional
codes, and customer requirements.

3. Select a suitable location and mark the anchor
points. Ensure that the enclosure is level. See
Figure 5 for an example.

4. Drill the appropriate holes in accord an ce w ith th e
type of wall anchor used.

5. Install the enclosure on the wall.

IMPORTANT: Be careful not to damage the circuit
boards during installation.

6. Check that the mounting is secure and the wiring
connections are correct and tight. Check that no
loose wire strands or other metal objects that could
cause a short circuit are on the circuit board.

7. Complete wiring as described in the Applying
Power section.

Applying Power

When using an enclosure type of E-Link Gateway,
power can be supplied from either a separate power
supply or the main terminal strip in the chiller panel.
Locate the power source within 0.9 m (3 ft) of the
E-Link Gateway, and protect it with a suitable fuse or
circuit breaker. Ensure th e power is supplied from a
dedicated source and not controlled by a programmed
switch.

If the enclosure is mounted on a wall, the wiring from
the power source to the E-Link Gateway must always
run in a suitable conduit. To obtain the best
Electromagnetic Interference (EMI) and
Electromagnetic Compatibility (EMC) performance,
ensure that the conduit is bonded to the metal of both
enclosures. Scraping the paint around the knockouts
usually helps provide a better electrical connection
between the joining parts.

WARNING: Risk of Electric Shock.

Disconnect or isolate all power supplies
before making electrical connections.
More than one disconnect or isolation
may be required to completely
de-energize equipment. Contact with
components carrying hazardous voltage
can cause electric shock and may result
in severe personal injury or death.

CAUTION: Risk of Property Damage.

Do not apply power to the system before
checking all wiring connections. Short
circuited or improperly connected wires
may result in permanent damage to the
equipment.

E-Link Gateway Installation Instructions6

1. Connect a 1.29-1.02 mm (16-18 AWG) wire from a
reliable ground reference to the E-Link Gateway’s
incoming power ground lug. Do not remove the
existing wire that connects the ground lug to the
enclosure cover.

2. On 120 VAC applications, connect the Hot wire to
TB2 and the Neutral wire to TB1. Connect the
ground wire to a ground lug.

On 240 VAC applications, connect the Hot wire to
TB3 and the Neutral wire to TB1. Connect the
ground wire to a ground lug.

IMPORTANT: Use copper conductors only.
Make all wiring connections in accordance with
local, national, and regional regulations. Do not
exceed the E-Link Gateway’s electrical ratings.

1. Apply power and verify that the red power

Table 9), select the appropriate settings on
GROUP A and GROUP B switches. For equipment
points lists, refer to the Johnson Controls Portal

(Products and Services>Delivery>Products/
Service Field Support>Equipment
Integration>YORK Equipment Data Maps).

Commissioning a Standard Application

Once the E-Link Gateway has been mechanically and
electrically installed (that is, it has been located in its
enclosure, wired, and terminated appropriately), it may
be Quick Commissioned.

3. Press, hold a few seconds, then release the push
button shown in Figure 11. The status LED flashes
quickly. After the E-Link Gateway re-initializes, the
commissioning is complete.

4. When commissioning a

LONWORKS BAS output

protocol, disconnect the BAS network and cycle
the power on the E-Link Gateway to activate the
Quick St art and the

LONWORKS FTT10 ProtoCessor.

The ProtoCessor does not recognize the push
button as a trigger to reset and load the correct
conversion file. Wait a minimum of 10 minutes
before reconnecting the BAS network.

5. Check the E-Link Gateway’s LEDs. First, check the
ST ATUS LED; if the E-Link Gateway has no errors,
it flashes continuously (1/2 second on, 1/2 second
off). If the LED is not flashing continuously, see
Table 6 for possible reasons.

Figure for the location of Port 2 communication LEDs.

What You Should Know before Using Quick Starts

The E-Link is designed to use a set of predefined data
maps to associate equipment data with a set of fixed
BAS network variables. You are not able to make any
field changes to these data maps; attempting to do so
results in the automatic reversal of any edits that you
may have made. For any field patches, refer to your
local FSC (Field Support Center) for guidance.

The data maps used by the E-L i nk Gate way ar e based
on a collection of version controlled equipment point
lists, which are supplied by the equipment business for
the purpose of integrating equipment into BAS
networks. Unless noted otherwise, the equipment’s
data is available in these supported BAS protocols:
BACnet MS/TP, N2,

LONWORKS, and Modbus RTU.

The first release of the E-Link was positioned to
provide the equivalent functionality as offered by the
YORK MicroGateway. That release requires you to
reference point lists which are version J or earlier. All
subsequent E-link releases use point lists version K or
later.

Table 7: E-Link Releases

Firmware/Database Revision Point Lists

SSM4567 JCF0003BL.BIN J and earlier only
SSM4567 JCF0008BL.BIN J and earlier, or K

Quick Starts 1 through 16 all use the J version point
lists, whereas Quick Starts 17 through 33 use the K
version. The primary difference between the two
categories is that Quick Starts 1 through 16 have
limited network visible points. In this case, the available
points are those which were originally available at the
time when the MicroGateway was first released.

Quick Starts 17 and higher offer a much richer
equipment point compliment that is more reflective of
what the equipment currently makes available today.
These Quick Starts also create profiles that use more
descriptive BACnet point names, use engineering
units, and follow the BACnet Testing Laboratories™
(BTL) guidelines for compliance as a B-ASC contro ller.

In most cases, using a Quick Start that corresponds to
the equipment being integrated is sufficient to configure
the E-Link Gateway for operating on the BAS network;
however, in some circumstances, you will be required
to provide further customizing by connecting a laptop
computer onto Port 3 and then accessing the User
Reports (refer to the E-Link Gateway Commissioning
and Troubleshooting Technical Bulletin [LIT-12011238]
for more information).
