1769-L31 CompactLogix Controller 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.
1769-L31 CompactLogix Controller 3 Environment and Enclosure Information ATTENTION This equipment is intended for use in a Pollution Degree 2 industrial 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.
1769-L31 CompactLogix Controller 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.
1769-L31 CompactLogix Controller 5 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. North American Hazardous Location Approval The following information applies when operating this equipment in hazardous locations. Informations sur l’utilisation de cet équipement en environnements dangereux.
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.
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 WARNING 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.
1769-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.
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.
1769-L31 CompactLogix Controller 2. Check that the lever of the adjacent module (A) is in the unlocked (fully right) position. C A D B F E B 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.
1769-L31 CompactLogix Controller 11 Mount the System Maintain spacing from enclosure walls, wireways, and adjacent equipment. Allow 50 mm (2 in.) of space on all sides, as shown. This provides ventilation and electrical isolation. Dimensions are in mm (in.) in the figure. IMPORTANT ATTENTION When attaching the controller, power supply, and I/O modules, make sure the bus connectors are securely locked together to be sure of proper electrical connection.
1769-L31 CompactLogix Controller Product Dimensions Dimensions are in mm (in.) in the figure. Hole spacing tolerance is + 0.4 mm (0.016 in.) 15 mm (.59 in.) 67.5 mm (2.68 in.) 52.5 mm (2.06 in.) 70 mm (2.76 in.) 35 mm (1.38 in.) 132 mm (5.20 in.) 118 mm (4.65 in.) 52.5 mm (2.07 in.) IMPORTANT 35 mm (1.38 in.) 35 mm (1.38 in.) 35 mm (1.38 in.) 35 mm (1.38 in.) Compact I/O expansion cables have the same dimensions as the end caps. Expansion cables can be used on either the right or left end.
1769-L31 CompactLogix Controller 13 Panel Mounting Mount the controller to a panel by using two screws per module. Use M4 or #8 panhead screws. Mounting screws are required on every module. IMPORTANT The grounding tab, located where you install the mounting screws, enables the module to be grounded when it is panel-mounted. This procedure lets you use the assembled modules as a template for drilling holes in the panel. Due to module mounting hole tolerance, it is important to follow these procedures. 1.
1769-L31 CompactLogix Controller 6. Attach the modules to the panel by using the mounting screws. IMPORTANT If mounting more modules, mount only the last one of this group and put the others aside. This reduces remounting time when you are drilling and tapping the next group of modules. 7. Repeat steps 1...6 for any remaining modules. DIN Rail Mounting The controller can be mounted on the following DIN rails: EN 50 022 - 35 x 7.5 mm (1.38 x 0.30 in.) EN 50 022 - 35 x 15 mm (1.38 x 0.59 in.
1769-L31 CompactLogix Controller 15 Make RS-232 Connections to the Controller Connect the 9-pin female end of the serial cable to the serial port of the controller. WARNING If you connect or disconnect the serial cable with power applied to this module or the serial device on the other end of the cable, 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.

1769-L31 CompactLogix Controller 23 Using a CompactFlash Card to Load Firmware If you have an existing controller that is already configured and has firmware loaded, you can store the current controller user program and firmware on the CompactFlash card and use that card to update other controllers. 1. Use RSLogix 5000 software to store the controller user program and firmware of a currently configured controller to the CompactFlash card. 2.
1769-L31 CompactLogix Controller Select the Controller’s Operating Mode Use the keyswitch on the front panel of the controller to determine the controller’s operating mode. Keyswitch Position RUN Description Upload projects. Run the program and enable outputs. You cannot create or delete tasks, programs, or routines. You cannot create or delete tags or edit online while the keyswitch is in the RUN position.
1769-L31 CompactLogix Controller 25 Controller Status Indicators Indicator Status Description RUN Off The controller is in Program or Test mode. Solid green The controller is in RUN mode. Off No tags contain I/O force values. I/O forces are inactive (disabled). Solid amber I/O forces are active (enabled). I/O force values may or may not exist. Flashing amber One or more input or output addresses have been forced to an On or Off state, but the forces have not been enabled.
1769-L31 CompactLogix Controller Indicator Status Description OK Off No power is applied. Flashing red If the controller is new, the controller requires a firmware update. If the controller is not new, a major fault occurred. To clear the fault, either: turn the keyswitch from Prog to RUN to PROG. Solid red The controller detected a nonrecoverable fault, so it cleared the project from memory. Follow these steps to recover. 1. Cycle power to the chassis. 2. Download the project. 3.
