Installation Instructions

There are two methods of installation: Potting Method and Ring and Spring Method. The Potting Method procedure is suitable for use with other types of bearings and equipment, while the Ring and Spring Method instruction is EI 183 Temperature Detector in Bearing Shoe, Ring and Spring Method. A copy of EI 183 is included with each shipment and is also available at www.minco.com. The installation of the temperature detector in a bearing completes the enclosure and provides protection from mechanical impact.

Potting Method: The Potting Method procedure can be used with other types of bearings, and with equipment other than bearings.

1. Drill or bore a .193″ (4.90mm) diameter hole (#10 drill) into the bearing shoe where temperature detection is desired. The hole bottom may be left in the shape of the drill tip. However, a flat hole bottom will result in the detector having a faster response time to temperature change.
2. If the hole has a drill point, apply a small amount of silicone heat sink compound to the tip end of the temperature detector (Dow Corning’s #340 or similar compound is recommended). Apply enough compound to fill the drill tip cone at the bottom of the hole when the detector is installed.
3. Insert the detector into the hole until it reaches the bottom.
4. Pot the leadwire in place where it enters the shoe: use an epoxy or other suitable potting compound compatible with the bearing shoe materials, temperature, and service conditions. During application and curing of the potting compound, make certain the detector remains at the bottom of the hole.
5. When routing the leadwire from the bearing shoe, leave sufficient slack in the leadwire for movement of the shoe when it is in service. Use mechanical retainers to secure the leadwire externally to the shoe, or pot the leadwire in place using epoxy or other suitable potting compound.

Ring and Spring Method: The instruction for the Ring and Spring Method is EI 183 Temperature Detector in Bearing Shoe, Ring and Spring Method. A copy of EI 183 is included with each shipment and is also available at www.minco.com.

Product Usage Instructions

• Step 1 : Choose a suitable method of installation – Potting Method or Ring and Spring Method – based on the type of equipment used.
• Step 2 : For Potting Method, drill or bore a .193 (4.90mm) diameter hole (#10 drill) into the bearing shoe where temperature detection is required. For Ring and Spring Method, refer to EI 183 Temperature Detector in Bearing Shoe, Ring and Spring Method instruction available at www.minco.com.
• Step 3 : Using Dow Corning #340 or equivalent, pot the detector into the drilled hole or install using the Ring and Spring Method.
• Step 4 : Connect the detector using the appropriate electrical connections based on the number of leads required for the specific application.
• Step 5 : Refer to the ATEX and IECEx certificates for any special conditions of use.

Description
