How to install Johnson AE55/NIE55?

Equipment Overview and Application Scenarios

core positioning

NAE (Network Automation Engine) and NIE (Network Integration Engine) are monitoring devices that support web access and are based on Ethernet. Their core functions are to monitor and control on-site building automation equipment, HVAC equipment, and lighting systems. Unless otherwise specified in the document, the MS-NAE55xx-x and MS-NIE55xx-x series are collectively referred to as NAE55.

Emission compliance requirements

United States: Compliant with FCC Part 15 Class A digital device restrictions, only applicable to commercial environments. If interference occurs in residential environments, users need to resolve it themselves.

Canada: Meets the requirements of the Canadian Interference Equipment Regulations (R è glement sur le mat é riel brouilleur du Canada).

Preparation before installation

Package contains components

1 NAE55 host

1 data protection battery (individually packaged)

1 installation manual

Required materials and specialized tools

4 fasteners for compatible mounting surfaces (M4 screws for Europe, # 8 screws for North America)

2 sections of DIN rails 36 centimeters (14 inches) and above (only for DIN rail installation scenarios)

1 small flathead screwdriver (used to fix the communication cable of the terminal block)

Installation environment requirements

Stay away from corrosive gases and follow the environmental restrictions specified in the technical specifications.

Avoid installing on surfaces that are prone to vibration (such as pipelines) or near electromagnetic interference sources (to prevent interference with communication).

Reserve sufficient space for wiring and terminal connections (refer to size requirements in Figure 2).

The power supply should not be installed below NAE55.

When installing panels/enclosures, it is necessary to avoid sealing the enclosure and ensure that the enclosure walls or transformers do not obstruct the equipment ventilation openings.

Devices that cause the temperature of the NAE55 processor to exceed 77 ° C (171 ° F) must not be added inside the casing (embedded temperature sensor data must be viewed through diagnostic tags).

Installation process

Installation method selection

NAE55 supports three installation methods: wall mounting, DIN rail mounting, and shell mounting. The core operations are as follows:

1. Wall installation (vertical surface)

Mark the four installation hole positions on the wall according to the dimensions in Figure 3 (horizontal installation hole spacing of 317.5mm, vertical installation hole spacing of 63.5mm) or directly using the host as a template.

After drilling, if anchor bolts need to be fixed, they should be inserted into the holes. First, screw the screws into the top two holes, leaving enough space to accommodate the installation feet.

When installing horizontally, hang the top mounting foot of the host on the screw; When installing vertically, the host needs to be held in a fixed position.

Insert the screws into the two holes at the bottom, being careful not to tighten them too tightly (to avoid damaging the mounting feet or housing).

2. DIN rail installation

Install two sections of DIN rails horizontally, with a center to center distance of 125 millimeters (4.9 inches).

Pull the DIN buckle at the bottom of the host to the outer position.

Hang the DIN rail hook on the back of the host onto the rail.

Push the DIN buckle back to its original position and secure the host.

Disassembly steps: First, move the DIN buckle to the outside, and then remove the host from the guide rail.

3. Shell installation

Install the casing according to the manufacturer's instructions.

Following the "Installation Environment Requirements" and the above installation specifications, fix NAE55 inside the casing.

Special installation requirements

The UL 864 certified models (MS-NAE5510-0U and MS-NIE5510-0U) must be installed inside a lockable housing.

Wiring operation

Precautions before wiring

Before wiring, a data protection battery must be installed (see "Settings and Adjustments" section), and a 24VAC power supply must not be connected.

Only copper conductors are used, and wiring must comply with local, national, and regional regulations.

Do not exceed the electrical rating of the equipment (NAE55 is a low-voltage equipment,<30VAC), and do not connect to high voltage (otherwise the equipment will be damaged and the warranty will be invalidated).

The terminal block key must not be removed, and the terminal plug and socket are designed to be foolproof and can only be correctly connected.

Prevent electrostatic discharge (avoid damaging equipment and void warranty).

The power cord and communication cable should be kept at least 50 millimeters (2 inches) away from the ventilation duct on the side of the equipment.

Reserve a certain degree of slack in the cables, and arrange the wiring neatly to ensure ventilation, LED visibility, and maintenance convenience.

Core wiring steps

Ethernet connection: Insert the Ethernet cable into an 8-pin RJ-45 Ethernet port (supporting 10/100 Mbps).

Building Automation System (BAS) Network Connection:

N2 or MS/TP network: Connect three bus lines to a 4-terminal plug labeled FC A or FC B (Figure 6).

LONWorks compatible network: Connect the bus line to a 3-terminal plug (Figure 7), and there is no polarity requirement for the network wiring.

Note: The N2 and BACnet MS/TP bus protocols are different and cannot be connected to the same FC bus port; If connecting to N2 or MS/TP bus, an End of Life (EOL) switch needs to be set up (see "Settings and Adjustments" section).

Modem connection: If needed, connect the phone line to the MODEM port (built-in modem model), or connect an external modem to the USB A port.

RS-232 serial port connection (if required): Use a 9-pin male to male null modem cable to directly connect to a computer, only for point-to-point protocol (PPP) network connection (Serial A port) or obtaining an IP address (Serial B port).

Power connection: Connect the power cord of the 24VAC transformer to the power terminal block (Figure 8) to ensure that the transformer phases of all network devices are consistent (reducing interference and grounding loop issues).

Different network topology wiring specifications

Core limitations and requirements for network types

The N2 network supports 100 devices on a single bus, with a maximum cable length of 1500 meters without repeaters; Recommended 1.5mm ² (18 AWG) 3-core wire,+/- bus must be twisted pair

BACnet MS/TP network supports 100 devices on a single FC bus, with a cable length of 1500 meters without repeaters; Recommended 0.6mm (22 AWG) 3-core shielded twisted pair cable

Ethernet network star topology (requiring network hub/switch), with a maximum of 100 devices connected to a single site

LONWorks network bus topology stub cable with a maximum length of 3 meters; FTT-10 nodes can have a maximum of 64 (without repeaters) or 128 (with repeaters); Install corresponding terminators according to topology type

Settings and Adjustments

Install data protection battery

Remove the battery and open the battery compartment cover on the device (Figure 1).

Connect the connector of the battery cable to the connector inside the battery compartment.

Place the battery in the compartment and secure it with a battery strap (pass through the hole and fasten to reduce movement).

Cover the cabin and immediately connect the 24VAC power supply (to avoid battery depletion and damage).

Attention: The battery can only provide data protection in the event of a power outage after at least 2 hours of initial charging. Full charging (24 hours) can support three consecutive power outages for protection; The battery model is MS-BAT1010-0, with a service life of 3-5 years (at 21 ° C).

Set End Connection (EOL) switch

The devices at both ends of the FC bus section need to be set as network termination devices, and each FC port of NAE55 corresponds to a set of EOL switches:

If NAE55 is an FC bus termination device, set both sets of EOL switches for the corresponding ports to the ON position (default factory ON).

If it is not a terminating device, turn the switch to positions 1 and 2.

Startup and shutdown operations

boot process

Confirm that all wiring is correct and the battery is installed.

Connect the 24VAC power supply, and the device will take up to 5 minutes to start.

Startup completion indicator: The green RUN LED is constantly on, and the red GEN FAULT LED is off.

LED test sequence at startup

After the power is turned on, the PEER COM, RUN, GENL FAULT LEDs (NAE55 also includes FC A, FC B) light up, indicating that the operating system is started.

The above LED is off and the RUN LED is flashing, indicating that the device software is loading.

The LED displays the running status of the device, and if the RUN LED is constantly on, it indicates that the device is ready.

Shutdown process

Disconnect the 24VAC power supply (unplug the power terminal block plug).

The device is powered by a data protection battery and continues to operate for 1-8 minutes (backup volatile data) until the POWER LED goes out.

If the power outage exceeds 48 hours, the data protection battery should be removed after the POWER LED is turned off (to avoid battery depletion and damage).

System restart switch

The System Re Boot switch (Figure 1) can only be pressed when the device is unresponsive and cannot be accessed through the user's device. Restarting will lose the data saved last time (including alarm, trend, and audit tracking data), and other troubleshooting methods should be attempted first.

Troubleshooting

LED status indication (core reference)

Meaning and handling suggestions for abnormal LED names in normal states

POWER (green) constantly on and off indicates that the device is turned off; Always on indicates power supply from battery or 24VAC

ETHENET (green) flashing off indicates no Ethernet traffic, possibly due to network failure or poor connection

FC A/FC B (green) flashing constantly indicates that the port has defined a controller but there is no communication; Extinguish indicates no controller definition (NIE55 does not have this port)

BATT FAULT (red) is off and constantly on, indicating a battery fault (not connected, unable to charge). If it still lights up after 48 hours, check the connection or replace the battery

GENL FAULT (red) off and constantly on indicates general faults (such as high CPU/memory usage, high temperature, battery failure, etc.)

Common problem handling

Battery failure: Check the battery connection. If the connection is normal but still reports an error, replace the MS-BAT1010-0 model battery.

Communication failure: Confirm that the cable connection is correct, the topology meets specifications, the EOL switch setting is correct, and stay away from electromagnetic interference sources.

High temperature: Check the equipment combination inside the casing to ensure that there are no excessive heating devices and good ventilation.
