User personnel must be completely familiar with the following operating and maintenance instructions before attempting to service this equipment.

4 Introduction The CR7160 Limitamp Controller, a quality GE product, was designed and manufactured to give long and satisfactory service. This bulletin contains items that, through normal use, may require periodic replacement; other items may never need service or replacement during the useful life ofthe equipment. Reference Publications GEH-3091 Instructions for Air Break Controllers GEH Instructions for Contactor GEH Application Data GET Application and Selection Guide GEH CR7160 Draw out Vacuum Contactor For additional assistance, please refer to factory. Parts Identification This bulletin will provide the information necessary to identif}', by description or actual catalog number, replacement parts for CR7160 Limitamp Motor Controllers. The following pages will describe where important equipment identification numbers can be found and provide catalog numbers for assemblies and individual parts that may require periodic replacement through normal wear. Table 1. CR7160 Publication Abbreviations High-Voltage Contactor Nameplate High-voltage contactor renewal parts are found in separate renewal parts publications depending on the contactor catalog number. This catalog number is found on the contactor nameplate mounted on the steel bracket directly above the contactor coil. An example of this nameplate is shown below: Figure I. High-Voltage Contactor Nameplate The proper publication can be selected from the following table: Table 2.

In order for the factory to provide assistance in identifying the part, the Catalog Number and Diagram Number of the equipment must be known (see Limitamp Panel Data Nameplate). 2

5 Limitaml' Medium Voltage Motor Control Limitamp Panel Data Nameplate This nameplate is mounted near the starter handle operator on the high-voltage door. It contains all the necessary information for the factory to positively identify the starter and its bill of material. This information must accompany all part orders and quotation requests. An example of this nameplate is shown below: ~gg~te DIAGRAM 221 B3466 SCHEMA-~-----,-, '---- POWER FUSE CAT.NO A4~2-9~1P~ ~R=B~----'- FUSIBLE DE PUIS., N CAT.

CAUTION BEFORE INSTALLING OR OPERATING READ INSTRUCTIONS ATTENTION.. LIRE LES INSTRUCTIONS AVANT DE PAOC!:'DEA At:INSTALLATION GEH-3091 GEH,3102 Catalog Numbering System Limitan1p control is manufactured in three construction types: one-high, two-high and three-high. One-high construction consists of one medium-voltage contactor in one 90.inchhigh enclosure. Two-high construction contains two mediumvoltage contactors in one 90.inch-high enclosure. Three-high construction has three medium-voltage cont.actors in one 90- inch-high enclosure. You should first determine the construction type ( one-high, two-high or three-high) ofyour equipment. After determination, the following pages should be consulted: Pages 4 and 5 for one-high construction Pages 6 and 7 for two-high construction Pages 8 and 9 for three-high construction Caution should be observed in that a part number in onehigh construction may have a different description and catalog number than the same part number in two- or three-high construction. Another method of identifying construction is through the controller "CR" number (shown on the panel data nameplate). Example: Catalog Number 7160Al 18G. 11ze alpha suffix determines one-high, two-high or three-high; G is one-high, K is two-high and His three-high. Vacuum starters are designated by an M suffix. Example: Catalog Number 7160Al 18G1vl. This "CR" number is further referenced in GEH DO NOT OPERATE STARTERS FURNISHED WITH CURRENT TRANSFORMERS UNLESS RELAY ELEMENJS ARE INSTALLED. NE PAS UTILISER LES DEMARREURS f-ournis AVEC LES TRANSFORMATEURS DE COURANT AVANT QUE LES RELAIS SO!ENT INSTALlES Figure 2, Limit.amp Panel Data Nameplate The required information is the catalog number and the diagram number. The catalog number from the sample above is 0607X0431V02 AOL The number can be broken down as follows: 0607X0431 is the material list number or shop order number for the job, V02 is the overall lineup designation, and AOl is a section in that lineup. The diagram number identifies the group of drawings that pertain to this particular project order. Sections that do not have a panel data nameplate vvill have a compartment nameplate mounted on the right side door flange. An example is shown below; Figure 3, Limitamp Compariment Nameplate This will provide the catalog number only. The diagram number can be obtained from any PanelDataNameplateon that lineup. 3

12 Handle Assembly The non-load break isolating mechanism (handle assembly) is a complex construction requiring a special bench fixture to assemble and adjust the mechanical interlocking mechanisms. Therefore, we recommend the entire assembly be replaced if the handle mechanism becomes extensively damaged. Some parts of the handle assembly are replaceable and can be identified by part number as shown Entire assemblies are ordered by catalog number l l 6C9928G* (see Tables 6 and 7). The group number (G*) is found on an adhesive backed label stuck on the underside of the handle housing (see Figure 12). For G51, G52 and G55, order replacement assemblies Gl, G2 and G5 respectively. Entire assemblies can be ordered as follows: Table 6.
