DocumentDocumentIOM TopWorxTM engineers are happy to provide technical assistance on GOTM Switch products. However, it is the customer's responsibility to determine the safety and suitability of the product in their application. It is also the customer's responsibility to install the switch using the current electrical codes in their region. TM C7, C8, H7, H8, M7,M8, R7, SV7 Introduction GOTM Safety Related Switches operate on the principle of magnetic attraction, reacting to magnetic targets as they come within the switch's sensing range. Although switches vary in design according to their intended applications, all GO Switches use permanent magnets which, when actuated by the presence of a magnetic target, change the state of electrical contacts. Mounting Nuclear service GO Switches are immune to EMC and RF interference. Use non-ferrous, stainless steel mounting brackets only. Consult factory for available mounting kits. For the maximum rated sensing distance, avoid mounting near ferrous metals or in a ferrous metal bracket. Caution: Do not use excessive force on external threads when installing. The switch threads need to be properly torqued as indicated below when mounted to any fixture. Over-torquing or undertorquing the switch threads may cause the switch to operate improperly. TopWorx recommends a torque value of 35 lbs - ft. (47.45 Nm) with a tolerance of + /- 2 lbs.- ft. (2.71 Nm). The switch must be mounted on the bracket and bolted close to the end of its threads, near its center of mass. This eliminates undue stress caused by heavy cables, connectors, etc. H7, M7, & SV7 Specifications - SPDT Coaxial Sensing Distance w/ C-AMS7A Target Average Sensing 0.190" ± 0.040" (4.83 mm ± 1.02 mm) Average Reset 0.023" ± 0.010" (0.58 mm ± 0.25 mm) Coaxial Sensing Distance w/C-AMS12 Target Average Sensing 0.350" ± 0.025" (8.89 mm ± 0.64 mm) Average Reset 0.031" ± 0.015" (0.79 mm ± 0.38 mm) Pressure Rating At Sensing Surface: 2,000 psi (137.89 bar) Thread Options: 5/8"-18 UNF (Consult TopWorx for metric thread options) Operating Temperature: Qualified Life (Years) 5 Max.

C7, C8, H7, H8, M7,M8, R7 and SV-7 nuclear service GO Switches must be installed with TopWorx qualified target magnets. Reference sensing ranges in corresponding sections throughout the catalog. Sensing and differential of switch may vary depending on target travel direction. Configure mounting of the switch and/or target so that target passes within the sensing area without physically contacting the switch. Sensing range will vary according to switch and target mode. For heavy or inductive loads, arc suppression devices, or interposing relays are recommended for contact longevity. Contact factory for specifics. Installation must use included Jam nuts and Lock washers. Recommended installation distance is equal to the half of published sensing distance per switch.

One location Setting Up A Nuclear Service GO Switch For Optimum Performance Nuclear service GO Switches use permanent magnets and a push-pull plunger to control a set of dry contacts. When a target magnet enters the sensing area of the switch, it attracts the primary magnet, which pulls the connecting rod and common contact. The normally closed and normally open contacts change state. (Continued on page 2.) Page 1 IOM Attachment of Conduit or Cable Continued: The sensing distance recommended by TopWorx is the maximum distance between the switch and target magnet trip point. The average reset, also known as deadband or hysteresis, is the distance that the target magnet must move from the sensing area in order to allow the switch to reset. To apply the Nuclear service GO Switch and obtain the least differential, the direction the target approaches the switch must be considered (axial, radial). The measurements shown are nominal depending on the size of target magnet used in the application. Consult the coaxial sensing distance for each switch model listed in this IOM. With proper mounting, once the switch is set, the GO Switch will maintain calibration for life. See illustration below for correct switch alignment. C-AMS7A Target Magnet * C-AMS12 Target Magnet * The GO Switch must have a qualified QDC, a qualified sealed stainless steel conduit, or other types of qualified accepted seal when used in submerged applications or exposed to 100% humidity. For LOCA DBA type submergence, however, only the C7 switch has been qualified for this application. Per Qualtech Report No. TR-23009-14 Rev A, the EGS O-ring qualified life at continuous operation, without disconnection, is 25.1 years at 144.14 of (62.3 °C). If for any reason these assemblies need to be detached prior to installation or while in operation, the O-rings must then be replaced. The maximum shelf life that can be assigned for the O-Ring is 10 years from the cure date. As long as the O-Rings have been stored per the guidelines of ANSI N45.2.2, Level B (now ASME NQA-1, Part II, Subpart 2.2, Level B), the O-Ring may be placed into installed service any time prior to the shelf life expiration date without impinging on the qualified life outlined above All GO Switches are "pure" contact switches, meaning they have negligible voltage drop when closed, nor do they have any leakage current when open. For multi-unit installation, switches may be wired in series or parallel, as shown to the right. Series Wiring Any number of GO Switches may be wired in series, without voltage drop. Parallel Wiring Any number of GOTM Switches may be wired in parallel, with no current leakage and without drawing operating current. *Refer to switch specifications for average sensing distance. The target magnet threads need to be properly torqued when mounted to any fixture. The target magnets were mounted at a torque value of 35 lbs-ft (47.45 Nm) with a tolerance of + /- 2 lbs.-ft. (2.71 Nm) during seismic testing. TM C7, C8, H7, H8, M7,M8, R7, SV7 C7 & R7 SPDTC7 & R7 SPDT 4 COND. PeeCk47CC&aObNRleD7.SPPeDeTk Cable 4 COND.

Attachment of Conduit or Cable Attach conduit or cable correctly. The switch conduit or cable needs to be properly supported when mounted to any fixture. During seismic testing, the stainless steel conduit (with PEEK cable) was supported at 3.28 ft (1 m) from the back of the switch while the Rockbestos or PEEK cables were supported at 1 ft (0.305 m) away from the back of the switch. EGS Flex conduit and support kit are available from TopWorx as an option. During seismic testing of the C7 switch with EGS QDC and flex conduit, the flex conduit was supported 15"- 48" from the QDC interface. Please consult factory for more detailed information. If the switch is mounted on a moving part, be sure flexible conduit is long enough to allow for movement, and positioned to eliminate binding or pulling. For installation in hazardous locations, check local electrical codes. All conduit connected switches should be installed using proper installation methods. Special Conditions for Safe Use The field side wires should be protected against damage and terminated to a terminal or junction box suitable for the conditions of use. Due to the GO Switch's sealed construction, field service is not available. Refer to our trouble shooting guide for a possible solution. If problem persists, please contact the factory directly.
