FlexLogix Controller System 7 Removal and Insertion Under Power The FlexLogix controller, the extended-local I/O adapter, the communication daughtercards, and the I/O terminal bases cannot be removed or inserted under power.. However, you can remove and insert FLEX I/O modules while backplane power is applied and the system is operating. WARNING 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.
FlexLogix Controller System What You Need to Do Before you can install a FlexLogix controller or extended-local adapter, you must: ✓ Install steel, 35 x 7.55mm DIN rails (A-B part number 199-DR1; 46277-3) where you want to place the FlexLogix system components. The DIN rails for all FlexLogix system components, including all local and extended-local I/O modules, must be mounted on a common, conductive surface to ensure proper electromagnetic interference (EMI) performance.
FlexLogix Controller System 9 Step 1: Verify That You Have All the Components These components ship with the FlexLogix controller: • • • • • 1756-BA1 battery and label key one spring-clip connector plug for 24V power connection one screw-terminal connector plug for 24V power connection two 1492-EA35 DIN rail locks The system components you have depend on your application.
FlexLogix Controller System Step 2: Install the Battery ATTENTION WARNING Only install a 1756-BA1 battery. If you install a different battery, you may damage the controller. For safety information on the handling of lithium batteries, including the handling and disposal of leaking batteries, see Guidelines for Handling Lithium Batteries, publication AG-5.4. Store batteries in a cool, dry environment. We recommend 25°C with 40% to 60% relative humidity.
FlexLogix Controller System 11 Step 3: Install Communication Daughtercards (optional) WARNING If you insert or remove the card while host power is on, an electrical arc can occur. This could cause an explosion in hazardous location installations. For specific information about configuring the communication card (such as setting a node address), see the installation instructions for the communication card. 1. Turn off power to the controller. 2.
FlexLogix Controller System Step 4: Install the Controller 1. Position the FlexLogix controller on the DIN rail at a 5° angle and rotate the controller onto the DIN rail. A A locking tabs IMPORTANT You can mount the FlexLogix controller either vertically or horizontally (as shown). 2. Press the controller down onto the DIN rail until flush. The locking tabs will snap into position and lock the controller onto the DIN rail.
FlexLogix Controller System 13 4. Make sure power is not applied to the power supply. 5. Connect the power supply to the controller. The graphic below and its related instructions describe a 1794-PS13 power supply. WARNING If you connect or disconnect wiring while the field-side 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. + _ A + _ C B D E F G H a.
FlexLogix Controller System 6. Mount the I/O terminal bases on the DIN rail. A B A 31036-M For information about I/O terminal bases, see the FLEX I/O Terminal Base Installation Instructions, publication 1794-IN092. 7. Install the I/O modules. To install an I/O module, see the installation instructions for that module. Removing the controller If you need to remove the controller, follow these steps: 1. Turn off power to the controller. 2. Disconnect all cables from the controller. 3.
FlexLogix Controller System 15 Step 5: Install the Extended-Local Adapter (optional) 1. Position the 1794-FLA extended-local I/O adapter on the DIN rail at a 30° angle and rotate the adapter onto the DIN rail. 2. Press the adapter down onto the DIN rail until flush. The locking tab will snap into position and lock the adapter onto the DIN rail. If the adapter does not lock in place, use a screwdriver or similar device to move the locking tab down while pressing the adapter onto the DIN rail.
FlexLogix Controller System 4. Make sure power is not applied to the power supply. Connect the power supply to the adapter. This diagram and its related instructions describe a 1794-PS13 power supply. a. Connect +24V dc input to the left adapter connector, terminal A, to the bottom, left power connector, terminal G. b.

FlexLogix Controller System 17 7. Connect the adapter to the controller. LOCAL rail 1794-CE1 or 1794-CE3 cable LOCAL2 rail 31039-M The following diagram shows how you can also use the 1794-CE1, -CE3 cable to split a rail of I/O. You can split each rail only once. You can split a rail right after the controller (or adapter) or after any I/O module. For more information about the 1794-CE1, -CE3 cables, see the Interconnect Cable Installation Instructions, publication 1794-5.12.
FlexLogix Controller System Make an RS-232 Connection to the Controller The RS-232 port is a non-isolated serial port built-in to the front of the controller. serial port To connect to the serial port: 1. Determine whether you need an optical isolator. If you connect the controller to a device outside of the system’s enclosure, consider installing an isolator between the controller and device. One possible isolator is the 1761-NET-AIC interface converter.
FlexLogix Controller System 19 2. Select the appropriate cable. Are you using an isolator? no Use this cable: The 1756-CP3 cable attaches the controller directly to the controller. 1 CD 1 CD 2 RDX 2 RDX 3 TXD 3 TXD 4 DTR 4 DTR COMMON COMMON 6 DSR 6 DSR 7 RTS 7 RTS 8 CTS 8 CTS 9 9 If you make your own cable, it must be shielded and the shields must be tied to the metal shell (that surrounds the pins) on both ends of the cable.
FlexLogix Controller System 3. Connect the appropriate cable to the serial port on 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. 4. If necessary, attach the controller to the isolator.
