Introduction

The best solution for excessive line voltage variation is to correct anyfeeder problems in your distribution system. Where this does notsolve the line variation problem, or in certain critical applications, usea constant voltage transformer. If you require a constant voltagetransformer, connect it to the power supply and all input devicesconnected to the SLC 500 controller.Connect output devices on the same power line, but their connectionalong the power line is normally made before the constant voltagetransformer. A constant voltage transformer must have a sufficientpower rating for its load.Excessive NoiseWhen operating the SLC 500 controller in an environment with a highamount of electrical noise, give special consideration to the possibilityof electrical interference.The following reduces the effect of electrical interference.• SLC 500 controller design features• Proper mounting of controller within an enclosure• Proper equipment grounding• Proper routing of wires (power, communication, control lines)• Proper suppression added to noise generating devicesPotential sources of noise include inductive loads, such as relays,solenoids, and motor starters when operated by hard contacts likepush buttons or selector switches. Suppression may be necessary
