9–8 Maintaining Your Control System Replacing a Fuse on the Power Supply To replace a fuse on the power supply (except for the 1746-P4 which does not have a replaceable fuse), do the following: 1. Remove power from the SLC 500 power supply. 2. Open the door on the power supply and use a fuse puller to remove the fuse. ! ATTENTION: Use only replacement fuses of the type and rating specified for the unit. Improper fuse selection can result in equipment damage. 3. Install a replacement fuse. See page 2–11 for replacements. See the figure below for fuse placement. POWER Fuse 3-pin Jumper ! ATTENTION: The exposed pin on the 3-pin jumper is electrically live. Contact with the pin may cause injury to personnel. Publication <strong>1747</strong>-6.2
In this chapter, you will learn about: • calling Allen-Bradley for assistance • tips for troubleshooting your control system • troubleshooting the SLC 5/01 and SLC 5/02 processors • troubleshooting the SLC 5/03, SLC 5/04, and SLC 5/05 processors • troubleshooting your input modules • troubleshooting your output modules Calling Allen-Bradley for Assistance If you need to contact Allen-Bradley or local distributor for assistance, it is helpful to obtain the following (prior to calling): • processor type, series letter, operating system (OS) number (obtained from the status file), firmware (FRN) number (see label on side of processor module) • processor LED status • processor error codes (found in S:6 of status file) • hardware types in system (I/O modules, chassis) • revision of programming device (on the main menu of the Hand-Held Terminal or programming software) Publication <strong>1747</strong>-6.2
