1 INTRODUCTION
The Horner NX Series OCS is a cost effective family of high performance all-in-one controllers. The NX
features an advanced control engine, operator interface, local and remote I/O capabilities (including built-in
HSC and PWM for specific models), and a variety of communications options. The NX is extremely versatile,
adept at a variety of factory automation functions. The NX can be used to perform advanced machine control,
factory machine monitoring, RTU-type functions, and much more.

Environment Designed for installation in a NEMA 12 environment. Optional mounting kit HE-ACC006
allows mounting in a NEMA 4/4X or IP65 environment.
* Total ladder scan is impacted by several factors – logic, I/O, screen and communications update.
** Denotes 9-pin, 2-row, socket. The term DB9 is widely (but erroneously) used to specify a 9-pin RS-232 connector. The
correct specifier is either a DE-9S (socket) or a DE-9P (plug).

3 INSTALLATION PROCEDURE
3.1 Overview of Required Steps
1. Per the specifications of Figure 1 and Figure 2 – carefully prepare the panel cutout. Make sure the
corners of the cutout are square and free from burrs.
2. Place the OCS in the panel cutout. Secure the unit as shown in Figure 3 using the four (4) supplied
mounting clamps. Figure 4shows the possible clamping locations (10 possible), and the locations
recommended for most applications. For NEMA 4/4X washdown applications, the optional
accessory kit HE-ACC006 is required. This kit includes six additional mounting clips so that all
mounting locations can be secured to provide an optimum seal against leaking.
3. As a final step prior to commissioning, carefully remove the protective, plastic sheet from the front of
the unit. The protective, transparent sheet is used to protect the display window.
3.2 Dimensions

CAUTION: Remove the plastic sheet slowly, from corner to corner, so as not to stretch
the NX keypad/display overlay.

3.4.2 CAN Network Port and Wiring
See the latest edition of Horner’s CAN Networks Manual (MAN0799) by referring to the website location
listed Section 6: Technical Support in this document.
Note: To optimize CAN network reliability in electrically noisy environments, the V- CAN Ground needs to be
isolated from the primary input power supply ground.
3.4.3 RS-232/ RS-485 Programming Ports and Wiring
The NX features two active serial ports, accessible through three connectors. Port 1 and MJ1 share internal
OCS circuitry. These two ports can NOT be used simultaneously. Port CN1 has independent circuitry, and
can be used simultaneously to either Port 1 or MJ1.
Note: In certain applications, both Port 1 and MJ1 can be used, but the OCS application program must select
the port which is active at any given time. Table 4 shows the three port connectors and the functions
supported by each.

4 SAFETY
When found on the product, the following symbols specify:
Warning: Consult user documentation. Warning: Electrical Shock Hazard.
WARNING: To avoid the risk of electric shock or burns, always connect the safety (or earth)
ground before making any other connections.
WARNING: To reduce the risk of fire, electrical shock, or physical injury it is strongly
recommended to fuse the voltage measurement inputs. Be sure to locate fuses as close to the
source as possible.
WARNING: Replace fuse with the same type and rating to provide protection against risk of
fire and shock hazards.
WARNING: In the event of repeated failure, do not replace the fuse again as a repeated failure
indicates a defective condition that will not clear by replacing the fuse.
WARNING: Only qualified electrical personnel familiar with the construction and operation of
this equipment and the hazards involved should install, adjust, operate, or service this
equipment. Read and understand this manual and other applicable manuals in their entirety
before proceeding. Failure to observe this precaution could result in severe bodily injury or
loss of life.

Product and Installation
For detailed installation and a handy checklist that covers panel box layout requirements and minimum
clearances, refer to the hardware manual of the controller you are using. (See the Additional References
section in this document.)
• All applicable codes and standards need to be followed in the installation of this product.
• For I/O wiring (discrete), use the following wire type or equivalent: Belden 9918, 18 AWG or larger.
Adhere to the following safety precautions whenever any type of connection is made to the module.
• Connect the green safety (earth) ground first before making any other connections.
• When connecting to electric circuits or pulse-initiating equipment, open their related breakers. Do not
make connections to live power lines.
• Make connections to the module first; then connect to the circuit to be monitored.
• Route power wires in a safe manner in accordance with good practice and local codes.
• Wear proper personal protective equipment including safety glasses and insulated gloves when
making connections to power circuits.
• Ensure hands, shoes, and floor are dry before making any connection to a power line.
• Make sure the unit is turned OFF before making connection to terminals. Make sure all circuits are
de-energized before making connections.
• Before each use, inspect all cables for breaks or cracks in the insulation. Replace immediately if
defective.
