Each Mote takes about 5-10 minutes to mount. Start monitoring the health of your industrial machines in four simple steps: Step 1. Power up the Mote Step 2. Prepare the machine surface Step 3. Mix the epoxy Step 4. Mount the Mote What you will need: Petasense Motes CR123A 3V Batteries (Duracell recommended for longer battery life) Handheld rotary tool with sanding attachment (Dremel recommended) 2-part steel-enforced epoxy (JB Weld SteelStik recommended) - Safety Datasheet X-Acto knife Rubber gloves (for mixing epoxy) Soap Water (1:4 soap to water mixture) Shop towels Protective glasses Protective gloves Dust Mask Silicone/Lithium Grease 6 Mote Model 3 User Manual Mote Components: These instructions will reference specific components of the Mote as follows: 7 Mote Model 3 User Manual Before Getting Started 0.1 Confirm that your WiFi network has coverage in the machine areas. If possible, perform a brief site survey with a mobile device. 0.2 Prepare the appropriately sized pieces of 2-part steel-enforced epoxy. Each Mote requires a 2.5 3-gram piece of epoxy. Each tube of JB-Weld SteelStik will contain enough epoxy for approximately 20 Motes. 0.3 Document the allocation of your Motes very carefully. Keep a record of the serial numbers of your Motes and which machines they are mounted on. This attention to detail is essential for any successful asset monitoring program. Note: Before handling Petasense Motes, be sure to wash your hands to avoid getting dirt or other particles inside the device. Now, let's get started. Step 1. Power up the Mote 1.1 Remove the Mote cover and insert a new CR123A battery. The Mote will blink a series of yellow and red LEDs, ending with a slow, blinking green LED, indicating that the Mote has successfully connected to WiFi. If the Mote only blinks yellow and/or red, you will need to configure the Mote with the appropriate WiFi credentials before continuing. (See "How to Connect Vibration Motes to WiFi") 1.2 Once the Mote has connected to WiFi, replace the cover, place the device on the mount, place the S-ring over the top of the device and thoroughly tighten the S-ring clockwise at the base. *If using Model 2, please see further instructions below.* 8 Mote Model 3 User Manual Step 2. Prepare the machine surface 2.1 Identify a mounting location close to where the bearing is located on the machine. The ideal mounting location will be a rigid, flat surface. Avoid mounting on sheet metal covers, fins or other flimsy surfaces that are prone to rattle. 2.2 Use the rotary tool to strip the paint from the mounting location on the machine. 2.3 Apply Soap Water to a shop towel and wipe off any dirt or particles from the sanded mounting location. 9 Mote Model 3 User Manual 10 Mote Model 3 User Manual Step 3. Mix the epoxy 3.1 Wearing rubber gloves, knead one piece of 2-part steel-enforced epoxy thoroughly in your hand until the color is uniform. Ensure that the epoxy is in good condition (firm and slightly moist, not too hard or crumbly). Once the epoxy is mixed, you will need to apply it to the Mote quickly or it will start to harden. 3.2 Roll epoxy into a 2-3 inch strip, then form a ring on the bottom of the Mote mount. 11 Mote Model 3 User Manual Step 4. Mount the Mote 4.1 Place the Mote on the mounting location with the Petasense logo facing the closest machine shaft. Press down firmly for 15-20 seconds. Note: It is important that the Mote is mounted with the Petasense logo facing the direction of the machine's shaft for orientation purposes 4.2 Visually check that the epoxy is only bonding to the base of the Mote, not touching the knurled S-ring above the mount. If it is touching the S-ring, use the X-Acto knife to push the edges of the epoxy down toward the machine surface, so that the S-ring can be removed in the future for battery changes. Mounting Complete! 12 Mote Model 3 User Manual 13 Mote Model 3 User Manual How to Remove Petasense Motes Overview: Petasense Motes will need to be removed and reinstalled from time to time as your equipment will require maintenance or replacement. There are a few options when it comes to removing your Motes safely and efficiently. Option 1: Temporary removal of the Petasense Motes for equipment repairs/maintenance: If your equipment will be removed temporarily and reinstalled with the same configuration, Petasense Motes may also be removed and stored without going through the whole installation process. Step 1: With safety gloves on, secure the Mote with one hand and remove the S-Ring by turning counter-clockwise with your other hand. Once removed, please store the Mote and S-Ring together until re-mounting. The Mount can remain on the machine component for re-mounting later. 14 Mote Model 3 User Manual Step 2: Remove the CR123a Battery for storage or discard/recycle properly if spent. Step 3: After the equipment is reinstalled, re-insert a CR123a Battery and verify it has taken a reading with the Petasense Mobile App. Step 4: Remount the Mote by placing in the correct orientation on the mount and then fastening the S-Ring tightly (clockwise). Option 2: Permanent removal of Petasense Motes and Mounts In the case your equipment will be replaced with new components, you can safely remove the Mote and recover the Mount. Step 1: Follow the steps above to remove the Petasense Mote from the mount. Step 2: With a chisel and rubber hammer you can gently chip away the SteelStik Epoxy easily and recover the Mount. A Flathead Screwdriver can also be used in place of a chisel. 15 Mote Model 3 User Manual Step 3: Clean the Mount by chipping away any leftover epoxy residue with the Chisel/Rubber Hammer. A Handheld Grinder can also be used to clean the Mount. 16 Mote Model 3 User Manual Blink Up - How to Connect Vibration Motes to WiFi How to Connect Vibration Motes to WiFi Connecting Vibration Motes to your WiFi network is a quick and simple process, which utilizes a technology called Blink Up.
