ATC1510 Advanced Terminal Unit Controller
Installation Guide
About This Product
The Advanced Terminal Unit Controller (ATC) runs
custom, freely-programmed applications, and provides
the inputs and outputs required to monitor and control
a wide variety of HVAC/R equipment.
The ATCs operate as BACnet
®
Application Specific
Controllers (B-ASC) and integrate into Johnson
Controls
®
and third-party BACnet systems.
Communication Protocols
You can configure the field bus communication
protocol in the ATC as a standard BACnet MS/TP device
or an N2 protocol device. You can use the Controller
Configuration Tool (CCT) to switch the communication
protocol. Switchable communication protocols provide
a cost-effective upgrade and modernization path for
customers with existing N2 controllers.

a blue, removable, 4-terminal FC Bus block that
fits into a board-mounted jack. Wire the FC bus as
shown in Figure 1.
Note: Controllers can be daisy-chained by
inserting two wires into each connection.
Figure 1: FC Bus Terminal Block Wiring
2. Wire the SA Bus Terminal. The ATC features a
brown, removable, 4-terminal SA Bus block that
fits into a board-mounted jack. Wire the SA Bus as
shown in Figure 2.
Note:
- SA bus devices can be daisy-chained
by inserting two wires into each
connection.
- The SA BUS PWR terminal on the ATC
supplies 15 VDC, up to 210 mA. The
SA BUS PWR terminal can be used to
connect the 15 VDC power leads on
the SA Bus to power other devices
that are connected in a daisy chain
configuration. If a device has an SA
BUS PWR output, do not connect it to
the ATC SA BUS PWR output.

Input and Output wiring guidelines
Table 2 and Table 3 provide information and guidelines
about the functions, ratings, and requirements for the
controller input and output terminals, and guidelines
for determining proper wire sizes and cable lengths.
In addition to the wiring guidelines in Table 2 and Table
3, observe these guidelines when wiring controller
inputs and outputs:
• Run all low-voltage wiring and cables separate from
high-voltage wiring.
• All input and output cables, regardless of wire size
or number of wires, should consist of stranded,
insulated, and twisted copper wires.
• Shielded cable is not required for input or output
cables.
• Shielded cable is recommended for input
and output cables that are exposed to high
electromagnetic or radio frequency noise.
• Inputs/outputs with cables less than 30 m (100 ft)
typically do not require an offset in the software
setup. Cable runs over 30 m (100 ft) may require an
offset in the input/output software setup.

ATC1510 Advanced Terminal Unit Controller Installation Guide12
Setup and adjustments
Configuring N2 communications
N2-capable controllers support the full range of
possible N2 device addresses provided by the N2
protocol standard (1-254).
To configure a controller to communicate using the N2
protocol, complete the following steps:
1. Disconnect the 240 VAC supply from the
controller.
2. Set the address switches to the desired N2
address. For details about setting a device
address, see Setting the device address.
3. Reconnect the 240 VAC supply to the controller.
4. Using an SA bus connection, download the
firmware and controller application file configured
for N2 to the controller.
Switching the Communications Protocol
from N2 to MS/TP
For N2 sites that are converting to BACnet MS/TP,
you can switch the communications protocol of N2-
configured MS/TP controllers back to BACnet MS/TP.
To switch the ATC operating in N2 mode back into
BACnet MS/TP mode, complete the following steps:
1. Disconnect the 240 VAC supply from the
controller.
2. Set the address switches to the desired BACnet
MS/TP address. For details about setting a device
address, see Setting the device address.
3. Reconnect the 240 VAC supply to the controller.
4. Using an SA Bus connection, download a
controller application file configured for BACnet
MS/TP to the controller.
Setting the device address
Equipment controllers are master devices on MS/TP
(FC or SA) buses. Before you operate controllers on a
bus, you must set a valid and unique device address
for each controller on the bus. You set the ATC device
address by setting the positions of the Device Address
switch on the front of the controller.
The Technical Specifications table describes the valid
device addresses for communications bus applications.
The device address must match the device address
defined in the Controller Configuration Tool (CCT)
under Define Hardware > Network Settings.
To set the device addresses on the ATCs, complete the
following steps:
1. Set a unique and sequential device address for
each of the equipment controllers connected on
the FC or SA Bus.
2. To ensure the best bus performance, set
sequential device addresses with no gaps in the
device address range (4, 5, 6, 7, 8, 9, and so on).
The equipment controllers do not need to be
physically connected on the bus in their numerical
device address order.
Setting up a local display
ATC models do not have an integral display, but can be
connected to a DIS1710 Local Controller Display. For
detailed information about setting up and operating
a remotely connected DIS1710 display, refer to the
DIS1710 Local Controller Display Technical Bulletin
(LIT-12011270) .
Input/Output Wiring Validation
The ATCs ship with a default state that can assist in
validating the wiring of the input and output terminals
prior to download of an application file. When the
controller is powered on in this state, the Fault LED will
flash in a pattern of two quick blinks and then a long
pause (see Table 6).
To make use of this feature, make sure that you set
the device address and wire the input and output
terminals. Apply power to the ATC and connect to the
device with either a MAP Gateway or MS-DIS1710-0
Local Display to view the points in the controller. The
ATC reports an Operational status even though there
is no true application loaded. CCT will not be able to
commission or upload the device as a result until a
true application is downloaded. The application name
displayed will be the address of the controller followed
by the model of the controller and “Default State”.
For example, an ATC with device address set to 8 would
have the default state application name of “8-ATC
Default State”.
The default state creates I/O points for all connections
on the input and output terminals. It assumes all
Universal Inputs (UIs) are Nickel temperature sensors.
All Configurable Outputs (COs) are treated as Binary
Outputs (BOs) with an initial value of 0. The default
state also takes input from a Network Sensor at
address 199. If there is no connected Network Sensor,
the startup of this default state will be delayed by
ATC1510 Advanced Terminal Unit Controller Installation Guide 13
30 seconds as the controller attempts to establish
connection with the sensor.
For more details about the workflow, refer to FAN-410,
which can be downloaded from https://my.jci.com/
sites/BE/NASysOpsOn/Pages/home/welcome/
electrical.aspx.
Commissioning field controllers
You commission controllers with the Controller
Configuration Tool (CCT) software. You can connect the
controller using NxE Passthru (with network engines
(NxEs) at release 9.0.2 or above), MAP4.2+/BACnet
Router (Mobile Access Portal (MAP) Gateway at version
4.2 or above, or through Bluetooth (using BTCVT).
Refer to Controller Tool Help (LIT-12011147) for detailed
information about commissioning field controllers.
Note:
• You can use the Bluetooth connection to
Transfer to Computer (Upload) and commission
the controller, but you cannot use the
Bluetooth connection to Transfer to Device
(Download).
• The MAP Gateway serves as a replacement
for the BTCVT, which is no longer available for
purchase, but continues to be supported.
Firmware package file for CCT
The MS-FCP-0 equipment controller firmware package
files are required for CCT to configure and commission
the controllers. The firmware package files also allow
you to upgrade an existing controller to the latest
firmware release available for that controller.
Beginning at CCT Release 13, the firmware package
files are orderable separately; they are not included
with CCT. They are obtained from the Metasys software
licensing portal, and are loaded and licensed on the
computer/server that is running CCT.
For additional information about the firmware
package files, refer to the CCT Installation Instructions
(LIT-12011259).

Mounting
Mount the controller using a 35 mm DIN rail, or three screws and the integral
mounting clips on the controller.
Ensure that the controller is mounted so that the side with the outputs/power-
input is "up".
If IP20 covers are not in use, or if local regulations do not allow surface
mounting, the controller must be mounted in or on a panel.
The IP20 covers and cable strain reliefs have been designed to permit surface
mounting in certain countries.
