MicroLogix 1400 Programmable Controllers 17 Using the Battery The MicroLogix 1400 controller is equipped with a replaceable battery (catalog number 1747-BA). The Battery Low indicator on the LCD display of the controller shows the status of the replaceable battery. When the battery is low, the indicator is set (displayed as a solid rectangle). This means that either the battery wire connector is disconnected, or the battery may fail within 2 days if it is connected.

MicroLogix 1400 Programmable Controllers 23 Wiring Recommendation When wiring without spade lugs, 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. Finger-safe cover 44527 ATTENTION Be careful when stripping wires. Wire fragments that fall into the controller could cause damage.
MicroLogix 1400 Programmable Controllers Spade Lug Recommendation 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 the following spade lugs. The terminals will accept a 6.35mm (0.25 in.) wide spade (standard for #6 screw for up to 14 AWG) or a 4 mm (metric #4) fork terminal.
MicroLogix 1400 Programmable Controllers 25 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. You must also provide an acceptable grounding path for each device in your application.
MicroLogix 1400 Programmable Controllers The controller does not provide loop power for analog inputs. Use a power supply that matches the transmitter specifications as shown. The analog output can support a voltage function as shown in the following illustration.
MicroLogix 1400 Programmable Controllers 27 Minimizing Electrical Noise on Analog Channels Inputs on analog channels employ digital high-frequency filters that significantly reduce the effects of electrical noise on input signals. 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.
