Topics include: • wire requirements • using surge suppressors • grounding the controller • wiring diagrams • sinking and sourcing wiring diagrams • controller I/O wiring • wiring your analog channels • expansion I/O wiring Wiring Requirements Wiring Recommendation Before you install and wire any device, disconnect power to the controller system. Calculate the maximum possible current in each power and common wire. Observe all electrical codes dictating the maximum current allowable for each wire size. Current above the maximum ratings may cause wiring to overheat, which can cause damage. • United States Only. If the controller is installed within a potentially hazardous environment, all wiring must comply with the requirements stated in the National Electrical Code 501 -10 (b ). • Allow for at least 50 mm. (2 in.) between I/O wiring ducts or terminal strips and the controller. • Route incoming power to the controller by a path separate from the device wiring. Where paths must cross, their intersection should be perpendicular. Publication 1766- UM001A -EN -P - October 2008 42 Wiring Your Controller Do not run signal or communications wiring and power wiring in the same conduit. Wires with different signal characteristics should be routed by separate paths. • Separate wiring by signal type. Bundle wiring with similar electrical characteristics together. • Separate input wiring from output wiring. • Label wiring to all devices in the system. Use tape, shrink - tubing, or other dependable means for labeling purposes. In addition to labeling, use colored insulation to identify wiring based on signal characteristics. For example, you may use blue for DC wiring and red for AC wiring. Wire Requirements Wire Type Wire Size (2 wire maximum per terminal screw) 1 wire per terminal 2 wire per terminal Solid CAM (194 °F) #12 to #20 AWG #16 to #20 AWG Stranded I CAM (194°F) #14 to #20 AWG #18 to #20 AWG Wiring torque = 0.56 Nm (5.0 in -lb) rated Wire without Spade Lugs When wiring without spade lugs, it is recommended to keep the finger -safe covers in place. Loosen the terminal screw and route the wires through the opening in the finger -safe cover. Tighten the terminal screw making sure the pressure plate secures the wire. Publication 1766- UM001A -EN -P - October 2008 Finger -safe cover '.tai Wiring Your Controller 43 Wire with Spade Lugs The diameter of the terminal screw head is 5.5 mm (0.220 in.). The input and output terminals of the MicroLogix 1400 controller are designed for a 6.35 mm (0.25 in.) wide spade (standard for #6 screw for up to 14 AWG) or a 4 mm (metric #4) fork terminal. When using spade lugs, use a small, flat -blade screwdriver to pry the finger -safe cover from the terminal blocks as shown below. Then loosen the terminal screw. Finger -safe cover Using Surge Suppressors Because of the potentially high current surges that occur when switching inductive load devices, such as motor starters and solenoids, the use of some type of surge suppression to protect and extend the operating life of the controllers output contacts is required. Switching inductive loads without surge suppression can significantly reduce the life expectancy of relay contacts. By adding a suppression device directly across the coil of an inductive device, you prolong the life of the output or relay contacts. You also reduce the effects of voltage transients and electrical noise from radiating into adjacent systems. Publication 1766- UM001A -EN -P - October 2008 44 Wiring Your Controller The following diagram shows an output with a suppression device. We recommend that you locate the suppression device as close as possible to the load device. +DC or L1 Suppression Device Out 0 Out 1 AC or DC "'' VV Outputs Out 3 Load Out 4 Out 5 Out 6 Out 7 COM 1 DC COM or L2 If the outputs are dc, we recommend that you use an 1N4004 diode for surge suppression, as shown below. For inductive DC load devices, a diode is suitable. A 1N4004 diode is acceptable for most applications. A surge suppressor can also be used. See for recommended suppressors. As shown below, these surge suppression circuits connect directly across the load device. Relay or Solid State DC Outputs +24V do IN4004 Diode (A surge suppressor can also be used.) Suitable surge suppression methods for inductive AC load devices include a varistor, an RC network, or an Allen- Bradley surge suppressor, all shown below. These components must be appropriately rated to suppress the switching transient characteristic of Publication 1766- UM001A -EN -P - October 2008 Wiring Your Controller 45 the particular inductive device. See Recommended Surge Suppressors on page 45 for recommended suppressors.

Publication 1766- UM001A -EN -P - October 2008 46 Wiring Your Controller Grounding the Controller In solid -state control systems, grounding and wire routing helps limit the effects of noise due to electromagnetic interference (EMI). Run the ground connection from the ground screw of the controller to the ground bus prior to connecting any devices. Use AWG #14 wire. For AC- powered controllers, this connection must be made for safety purposes. All devices connected to the RS- 232/485 communication port must be referenced to controller ground, or be floating (not referenced to a potential other than ground). Failure to follow this procedure may result in property damage or personal injury. • For 1766132BWA and 1766- L32BWAA controllers, the COM of the sensor supply is also connected to chassis ground internally. The 24V DC sensor power source should not be used to power output circuits. It should only be used to power input devices. • For 1766- L32BXB and 1766- L32BXBA controllers, the VDC NEUT or common terminal of the power supply is also connected to chassis ground internally. This product is intended to be mounted to a well grounded mounting surface such as a metal panel. Refer to the Industrial Automation Wiring and Grounding Guidelines, publication 1770 -4.1, for additional information. Additional grounding connections from the mounting tab or DIN rail, if used, are not required unless the mounting surface cannot be grounded. Grounding Stamping Use all four mounting positions for panel mounting installation. 44519 on Remove the protective debris strip before applying power to the controller. Failure to remove the strip may cause the controller to overheat. Publication 1766- UM001A -EN -P - October 2008 Wiring Your Controller 47 Wiring Diagrams The following illustrations show the wiring diagrams for the MicroLogix 1400 controllers. Controllers with DC inputs can be wired as either sinking or sourcing inputs. (Sinking and sourcing does not apply to AC inputs.) Refer to Sinking and Sourcing Wiring Diagrams on page 3 -48. The controller terminal block layouts are shown below. The shading on the labels indicates how the terminals are grouped. A detail of the groupings is shown in the table following the terminal block layouts. This Usymbol denotes a protective earth ground terminal which provides a low impedance path between electrical circuits and earth for safety purposes and provides noise immunity improvement. This connection must be made for safety purposes on ac- powered controllers. This fi symbol denotes a functional earth ground terminal which provides a low impedance path between electrical circuits and earth for non - safety purposes, such as noise immunity improvement.

To help reduce the effects of environmental noise, install the MicroLogix 1400 system in a properly rated (for example, NEMA) enclosure. Make sure that the MicroLogix 1400 system is properly grounded. A system may malfunction due to a change in the operating environment after a period of time. We recommend periodically checking system operation, particularly when new machinery or other noise sources are installed near the MicroLogix 1400 system.

Publication 1766- UM001A -EN -P - October 2008 52 Wiring Your Controller Analog Output anseo Analog Channel Wiring Guidelines Consider the following when wiring your analog channels: • The analog common (COM) is connected to earth ground inside the module. These terminals are not electrically isolated from the system. They are connected to chassis ground. • Analog channels are not isolated from each other. • Use Belden TM 8761, or equivalent, shielded wire. • Under normal conditions, the drain wire (shield) should be connected to the metal mounting panel (earth ground). Keep the shield connection to earth ground as short as possible. • To ensure optimum accuracy for voltage type inputs, limit overall cable impedance by keeping all analog cables as short as possible. Locate the I/O system as close to your voltage type sensors or actuators as possible. • The controller does not provide loop power for analog inputs. Use a power supply that matches the transmitter specifications as shown below.

However, because of the variety of applications and environments where analog controllers are installed and operated, it is impossible to ensure that all environmental noise will be removed by the input filters. Several specific steps can be taken to help reduce the effects of environmental noise on analog signals: • install the MicroLogix 1400 system in a properly rated (i.e., NEMA) enclosure. Make sure that the MicroLogix 1400 system is properly grounded. • use Belden cable #8761 for wiring the analog channels, making sure that the drain wire and foil shield are properly earth grounded. • route the Belden cable separately from any AC wiring. Additional noise immunity can be obtained by routing the cables in grounded conduit. Grounding Your Analog Cable Use shielded communication cable (Belden #8761). The Belden cable has two signal wires (black and clear), one drain wire, and a foil Publication 1766- UM001A -EN -P - October 2008 54 Wiring Your Controller shield. The drain wire and foil shield must be grounded at one end of the cable.

Internal diagnostics are performed at both levels of operation. Both module hardware and channel configuration error conditions are reported to the controller. Channel over -range or under -range conditions are reported in the module's input data table. Module hardware errors are reported in the controller's I/O status file. Refer to the MicroLogix 1400 Programmable Controllers Instruction Set Reference Manual, publication 1766 -RM001 for more information. When a fault condition is detected, the analog outputs are reset to zero. Power -up Diagnostics At module power -up, a series of internal diagnostic tests are performed.

If condition persists, replace the module. Call your local distributor or Allen - Bradley for assistance. Troubleshooting Your System 205 Critical and Non - Critical Errors Non - critical module errors are recoverable. Channel errors (over -range or under -range errors) are non - critical. Non - critical error conditions are indicated in the module input data table. Non - critical configuration errors are indicated by the extended error code. See Extended Error Codes for 1762- IF2OF2 on page 207. Critical module errors are conditions that prevent normal or recoverable operation of the system. When these types of errors occur, the system leaves the run mode of operation. Critical module errors are indicated in Extended Error Codes for 1762- IF2OF2 on page 207. Module Error Definition Table Analog module errors are expressed in two fields as four -digit Hex format with the most significant digit as "don't care" and irrelevant. The two fields are "Module Error" and "Extended Error Information ". The structure of the module error data is shown below. Module Error Table "Don't Care" Bits Module Error Extended Error Information 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Hex Digit 4 Hex Digit 3 Hex Digit 2 Hex Digit 1 Publication 1766- UM001A -EN -P - October 2008 206 Troubleshooting Your System Module Error Field The purpose of the module error field is to classify module errors into three distinct groups, as described in the table below. The type of error determines what kind of information exists in the extended error information field. These types of module errors are typically reported in the controller's I/O status file. Refer to the MicroLogix 1400 Programmable Controllers Instruction Set Reference Manual, publication 1766 -RM001 for more information. Module Error Types Error Type Module Error Field Value Description Bits 11 through 09 (Binary) No Errors 000 No error is present. The extended error field holds no additional information. Hardware Errors 001 General and specific hardware error codes are specified in the extended error information field. Configuration Errors 010 Module- specific error codes are indicated in the extended error field. These error codes correspond to options that you can change directly. For example, the input range or input filter selection. Publication 1766- UM001A -EN -P - October 2008 Extended Error Information Field Check the extended error information field when a non -zero value is present in the module error field. See Extended Error Codes for 1762- IF2OF2 on page 207. If no errors are present in the module error field, the extended error information field is set to zero. Hardware Errors General or module- specific hardware errors are indicated by module error code 2. Configuration Errors If you set the fields in the configuration file to invalid or unsupported values, the module ignores the invalid configuration, generates a non - critical error, and keeps operating with the previous configuration. The table below lists the configuration error codes defined for the module.
