Important User Information

Solid state equipment has operational characteristics differing from those of electromechanical equipment. Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls (Publication SGI-1.1 available from your local Rockwell Automation sales office or online at http://literature.rockwellautomation.com) describes some important differences between solid state equipment and hard-wired electromechanical devices. Because of this difference, and also because of the wide variety of uses for solid state equipment, all persons responsible for applying this equipment must satisfy themselves that each intended application of this equipment is acceptable.

In no event will Rockwell Automation, Inc. be responsible or liable for indirect or consequential damages resulting from the use or application of this equipment.

The examples and diagrams in this manual are included solely for illustrative purposes. Because of the many variables and requirements associated with any particular installation, Rockwell Automation, Inc. cannot assume responsibility or liability for actual use based on the examples and diagrams.

			environment, in overvoltage Category II applications (as defined in IEC
			publication 60664-1), at altitudes up to 2000 meters (6562 feet) without
			derating.
			This equipment is considered Group 1, Class A industrial equipment according
			to IEC/CISPR Publication 11. Without appropriate precautions, there may be
			potential difficulties ensuring electromagnetic compatibility in other
			environments due to conducted as well as radiated disturbance.
			This equipment is supplied as open-type equipment. It must be mounted within
			an enclosure that is suitably designed for those specific environmental
			conditions that will be present and appropriately designed to prevent personal
			injury resulting from accessibility to live parts. The enclosure must have
			suitable flame-retardant properties to prevent or minimize the spread of flame,
			complying with a flame spread rating of 5VA, V2, V1, V0 (or equivalent) if
			non-metallic. The interior of the enclosure must be accessible only by the use
			of a tool. Subsequent sections of this publication may contain additional
			information regarding specific enclosure type ratings that are required to
			comply with certain product safety certifications.

Prevent Electrostatic Discharge

ATTENTION			This equipment is sensitive to electrostatic discharge, which can cause
			internal damage and affect normal operation. Follow these guidelines when
			you handle this equipment:
			Touch a grounded object to discharge potential static.

Wear an approved grounding wriststrap.

Do not touch connectors or pins on component boards.

Do not touch circuit components inside the equipment.

Use a static-safe workstation, if available.

Store the equipment in appropriate static-safe packaging when not in use.

ATTENTION					This product is grounded through the DIN rail to chassis ground. Use zinc
					plated yellow-chromate steel DIN rail to assure proper grounding. The use of
					other DIN rail materials (for example, aluminum or plastic) that can corrode,
					oxidize, or are poor conductors, can result in improper or intermittent
					grounding. Secure DIN rail to mounting surface approximately every 200 mm
					(7.8 in.) and use end-anchors appropriately.

6 1769-L31 CompactLogix Controller

Before You Begin

Use this document as a guide for installing the controller. Consider the following when planning your CompactLogix system:

The CompactLogix controller is always the leftmost module in the system.

The controller must be located within four modules of the system power supply. Some I/O modules may be located up to eight modules away from the power supply. See the documentation for your 1769 I/O modules for details.

The 1769-L31 controller supports as many as 16 I/O modules in a maximum of 3 I/O banks with 2 expansion cables.

Each I/O bank requires its own power supply.

Only one controller can be used in a CompactLogix system.

A 1769-ECR right end cap or 1769-ECL left end cap is required to terminate the end of the communication bus.

These components ship with the controller.

IMPORTANT		The 1769-BA battery is the only battery you can use with the 1769-L31 controller.
Component			Description
			1769-BA battery
			1747-KY controller key

You can also use these components with the controller:

1756-CP3 or 1747-CP3 serial cable to connect a device to the RS-232 port

1784-CF64 or 1784-CF128 industrial CompactFlash card to add nonvolatile memory

Publication 1769-IN069C-EN-P - May 2008

1769-L31 CompactLogix Controller 7

Connect the 1769-BA Battery

The controller is shipped with the 1769-BA battery packed separately. To connect the battery, follow this procedure.

ATTENTION					The 1769-BA battery is the only battery you can use with the 1769-L31
					controllers. The 1747-BA battery is not compatible with the 1769-L31
					controllers and can cause problems.
					When you connect or disconnect the battery, an electrical arc can occur. This
WARNING
					could cause an explosion in hazardous location installations. Be sure that
					power is removed or the area is nonhazardous before proceeding.
					For safety information on the handling of lithium batteries, including handling
					and disposal of leaking batteries, see Guidelines for Handling Lithium
					Batteries Technical Data, publication AG-5.4.

1. Remove the battery door by sliding it forward.

	IMPORTANT	Do not remove the plastic insulation covering the battery. The insulation is
		necessary to protect the battery contacts.

2. Insert the battery connector into the black receptacle on the board. The connector is keyed for installation with the correct polarity.

Publication 1769-IN069C-EN-P - May 2008

81769-L31 CompactLogix Controller

3.Insert the battery into the door, as shown.

4. Slide the battery door back until it clicks into position.

Install a 1784-CF64 or 1784-CF128 Industrial CompactFlash Card (optional)

ATTENTION			Do not remove the CompactFlash card while the controller is reading from or
			writing to the card, as indicated by a flashing green CF status indicator. This
			could corrupt the data on the card or in the controller, as well as corrupt the
			latest firmware in the controller.

The optional industrial CompactFlash card provides nonvolatile memory for a CompactLogix controller. The card is not required for controller operation.

Follow this procedure to install the card.

WARNING			When you insert or remove the CompactFlash Card while power is on, an
			electrical arc can occur. This could cause an explosion in hazardous location
			installations.
			Be sure that power is removed or the area is nonhazardous before proceeding.

1. Push the locking tab to the right.

Publication 1769-IN069C-EN-P - May 2008

1769-L31 CompactLogix Controller 9

2.Insert the industrial CompactFlash card into the socket on the front of the controller, noting that the label of the CompactFlash card faces toward the left.

3. Match the orientation arrow on the card with the arrow on the front of the controller.

4. To remove the CompactFlash card, push the locking tab away from the CompactFlash card and pull the CompactFlash card from the socket.

Assemble the System

The controller can be attached to an adjacent I/O module or power supply before or after

mounting.

This procedure shows you how to install the controller in a CompactLogix system.

WARNING			The CompactLogix controller is not designed for removal and insertion under
			power.
			If you insert or remove the module while backplane power is on, an electrical
			arc can occur. This could cause an explosion in hazardous location
			installations.
			Be sure that power is removed or the area is nonhazardous before proceeding.

1. Disconnect line power.

3.Use the upper and lower tongue-and-groove slots (B) to secure the modules together.

4.Move the module back along the tongue-and-groove slots until the bus connectors line up with each other.

5.Use your fingers or a small screwdriver to push the module’s bus lever back slightly to clear the positioning tab (C).

6.Move the module’s bus lever fully to the left (D) until it clicks, being sure it is locked firmly in place.

			When attaching the controller, power supply, and I/O modules, make sure the
ATTENTION
			bus connectors are securely locked together to be sure of proper electrical
			connection.

7.Attach an end cap terminator (E) to the last module in the system by using the tongue-and-groove slots as before.

8.Lock the end cap bus terminator (F).
