Getting started Typical installation A typical installation therefore involves one or more EDGE W-200 modules and a LoRaWAN™ receiver. Long-range wireless connectivity enables EDGE W-200 modules to be placed nearly anywhere in your building or site. In cases where the signal is not strong enough, a second LoRaWAN receiver may be required. Please contact Temptime service team for support. Temptime LoRaWan enabled solution EDGE W-200 module Page 11...
Getting started How to check your module’s wireless signal Note This section assumes that your Temptime LoRaWAN™ receiver (20-50005 ) is installed, configured, and running properly. See Temptime EDGE LoRa Gateway Receiver Configuration Guide for more details on the receiver component. To see whether an EDGE W-200 module is within wireless range of the receiver: 1. Press the pushbutton on the front of the module (short press). 2. If the module detects a receiver, the text “ACK_RECEIVED” (acknowledgment received) is displayed in the lower left-hand corner of the screen. Otherwise “ACK_NOT_RECEIVED” is displayed (see Appendix - Troubleshooting on page 28 of this document). Figure 3 – Confirming connection with LoRa Gateway receiver 3. If required, test various ranges by placing your module at different locations around your site and repeating this test. This informal site testing procedure will enable you to verify that all your modules are communicating correctly. Excessive obstruction, interference, or harsh conditions can affect wireless performance. Please contact Temptime technical support for specific cases if you have a module that is having difficulty reaching the receiver. Temptime LoRaWan enabled solution EDGE W-200 module Page 12...
Getting started Requirements and recommendations • The EDGE Gateway receiver runs continuously, 24/7/365, and should be connected to an Uninterruptible Power Supply (UPS) that protects against power surges and provides power to back up the receiver. • The EDGEConnect web application will show an alert clearly on the computer screen if a module is not communicating. You may also verify connections by pressing the pushbutton on the EDGE W-200 module and making sure “ACK_RECEIVED” is displayed. • Recommended maintenance and calibration procedures should be followed. Placing your EDGE module for best wireless performance For optimal operation, follow these recommendations when physically placing your device: • Do not place the module within 40 cm (16 in.) of another module. • Make sure the wireless module is not placed on an electrical conduit or cable tray (such as for computer network cables). For best results, place the module so that it faces the general direction of the receiver. • • Keep about 20 cm (8 in.) of clear space around the module. For example, a module that is “stuck” between two refrigerators may not communicate effectively. Make sure all cables, if any, are firmly attached and that sensors are properly inserted in the • appropriate chamber. Temptime LoRaWan enabled solution EDGE W-200 module Page 13...
Getting started Preparing mounting kit with a magnet (optional) Your EDGE W-200 module includes a plastic holder so you can mount the device easily on various surfaces. In addition to the provided screws, you will also find a magnetic pad with adhesive backing that you can attach to the holder and then adhere the holder to metal surfaces easily. Clean the back of the holder with a mild cleanser or alcohol. 2. Remove the protection from the adhesive pad on the magnet and place the magnet on the back of the holder Place the holder and magnet down on a flat surface and press down strongly for 30 seconds to firmly attach the magnet.

External Smart Sensors External Smart Sensors The procedures described in this document assume that your EDGE LoRa Gateway receiver is up and running, and that you have created an account on the EDGEConnect web application (with a voucher to authorize Cloud access). This section focuses on the physical aspects of the EDGE W-200 module. This image shows a EDGE W-200 module with an external PT100 sensor, connected via EDGE Smart Sensor technology. Figure 4 – EDGE W-200 wireless module with PT100 sensor Connecting Smart Sensors™ The EDGE W-200 module and external PT100 sensors (and dual temperature/humidity sensors) provided by Temptime are independent of each other with respect to calibration. A calibrated external sensor stores its own calibration parameters directly, and thus can be used with any EDGE W-200 module. EDGE W-200 modules with support for external sensors use a specially designed Temptime Smart Sensor technology that offers several key advantages with respect to conventional solutions: • Calibration correction parameters are stored directly in the Smart Sensor • Plug and play functionality with no special configuration on your part • Module independence from sensor type: any supported Temptime sensor can be used with any given EDGE W-200 module, simplifying repairs, swaps/standard exchange, and calibration cycles Temptime LoRaWan enabled solution EDGE W-200 module Page 15...

External Smart Sensors (Note: if you change the sensor on a functioning EDGE W-200 module, you must reconfigure the module on the server-side using the EDGEConnect Web application.) Insert the cable from your module into the keyed plug on the EDGE Smart Sensor connector. Figure 5 – Connecting your EDGE W-200 wireless module with an external sensor This feature offers an effective way to handle sensors at calibration time (depending on your standard operating procedure) without leaving your equipment unattended. Simply have a calibrated sensor on-hand and swap it with the one that needs calibration. Temptime LoRaWan enabled solution EDGE W-200 module Page 16...
External Smart Sensors Placing Smart Sensors™ 4.2.1 General note about sensor placement Given the extreme temperature ranges typically handled by PT100 sensors, please be sure to • use the PT100-compatible mounting system provided with your freezer, oven, nitrogen tank, or other equipment. As mentioned earlier, the EDGE wireless monitoring system supports three different PT100 temperature sensors, each designed for a different application and temperature range. Placement of your PT100 sensor(s) depends on the equipment you intend to monitor, as described below. In all cases described in this section, the plastic connector joining the module and the sensor must be in the same temperature space as the module, not the sensor. Note When routing the cable for any EDGE sensor, avoid direct contact with or close proximity placement of the sensor cabling with any high voltage wiring. Cabling should be placed with no less than a minimum of 5 cm (2 inches) distance from high voltage components. Also, avoid running the sensor cable in parallel with high voltage wiring. Your equipment may be different than that described here. Contact the manufacturer of your equipment for instructions regarding proper placement of the sensor. 4.2.2 PT100: -100°C to +150°C When installing a PT100 sensor in an ultra-low-temperature (ULT) freezer, it is easiest to proceed with a thawed freezer. When possible, route the sensor through the same access port used by the unit control sensor or an accessory port, such as that shown below in Figure 6. When routing the PT100 sensor through the same port used by the control sensor, Temptime recommends installing the sensor only after the freezer has reached a thawed state. To negate the possibility of condensation dripping on the electronics, avoid routing the cable in close proximity to any electrical enclosures. Mount the PT100 sensor as close to the unit control sensor as possible. When possible, we recommend mounting the sensor within 5 cm (2 inches) of the control sensor. When mounting the PT100 sensor, avoid direct contact with the wall of the freezer. This will ensure the sensor is mounted to permit measurement of air temperature only. Temptime LoRaWan enabled solution EDGE W-200 module Page 17...
Page 18
External Smart Sensors We do not recommend installing the sensor through the door gasket on a ULT freezer. This leads to excessive ice build-up and possible door damage as well as longer compressor run times that may result in other mechanical problems. The orange cable, which supports temperatures from -200°C to + 50°C, may be placed inside the freezer. Make sure you attach the sensor using the provided cable-ties and reseal any openings you may have unsealed to insert the sensor using permagum sealant. Figure 6 – Sample PT100 (-100°C to +150°C) for ULT freezer Temptime LoRaWan enabled solution EDGE W-200 module Page 18...
Page 19
External Smart Sensors 4.2.3 PT100: -200°C to +50°C PT100 sensors for LN2/cryogenic tanks must be mounted, when applicable, in close proximity to the unit display sensor. To avoid temperature measurement disappearances, recommends mounting the sensor at the Temptime same height as the display sensor. As an example, some freezers have an access panel on the back of the unit in which you may route the sensor cable up the back wall. Place the cable under the tank gasket utilizing the notch at the 12 o’clock position. We recommend the installation of permagum sealant where the cable passes through the notch. Depending on whether storing in vapor or liquid phase, place the sensor at a depth suitable for proper temperature monitoring. Figure 7 – PT100 (-200°C to +50°C) for nitrogen/cryogenic tank Temptime LoRaWan enabled solution EDGE W-200 module Page 19...
External digital sensors External digital sensors This image shows a EDGE W-200 module with an external digital sensor. External digital sensors do not connect to modules via the EDGE Smart Sensor solution. Therefore, calibration parameters must be managed using the EDGEConnect web application and EDGEConnect Mobile application for upload them to the module. Figure 8 – EDGE W-200 module with external digital sensor (optional cable lengths) Depending on the design of the space to be monitored, you may be able to pass the sensor through an access port or opening. We recommend that you use the access port or opening if one is available. 1. When installation permits routing the sensor cabling through an access port or opening, connect the male end of the sensor firmly into the female end of the EDGE wireless module. 2. When installation requires passage through the door gasket seal, connect the male end of the sensor into the female end of the provided flat cable adaptor by joining the connectors (without unscrewing them). Then connect the other end of the flat cable into the end of the EDGE wireless module. Temptime LoRaWan enabled solution EDGE W-200 module Page 20...
External digital sensors Connecting the sensor Simply join the sensor cable to the module cable as shown here: Insert the cable from your module into the keyed plug on the sensor connector. Figure 9 – EDGE W-200 module with external digital sensor (optional cable lengths) Placing the sensor 1. If you have an EDGE module with one or more external sensors, the best solution is to use the access port or opening to insert the sensor(s). Otherwise, run the temperature sensor into the enclosure via the door joint, taking care to place the flat cable flush with the joint. Installation through the door gasket on freezers may cause ice build-up inside the freezer and/or on the freezer door. This may result in damage to the freezer door if not properly maintained. When used with incubators, use of the flat cable may cause condensation, which could potentially increase the risk of contamination. 2. Clean the surface for the sensor using alcohol to remove any grease or dirt. 3. Attach one of the plastic cable holders to the sensor, remove the protective strip from the adhesive, and place the holder on the clean spot inside the enclosure.

External digital sensors 4. Place the sensor / flat ribbon cable connector on the inside of the chamber in the same manner, as shown here: Figure 10 – Sensor inside refrigerator chamber (modules with external sensor only) 5. Your mounting kit includes a plastic holder that can be mounted using the provided magnet, screws or Velcro®. Choose the method that is most appropriate for your situation and place the EDGE module as described in section 3.6 Placing your EDGE module for best wireless performance. For example: Figure 11 – EDGE module mounted on the refrigerator door 7. Attach or coil the excess cable neatly. Temptime LoRaWan enabled solution EDGE W-200 module Page 22...
Internal sensor Internal sensor EDGE W-200 modules with integrated temperature do not have a cable protruding from the side of the module, and you do not have to connect a sensor yourself. LCD display with module name, temperature, signal and battery indicators Push-button Figure 12 – Module with internal temperature sensor Placing modules with an internal sensor Depending on your refrigerator or freezer model, it may be better to leave the module sitting on a shelf inside the chamber rather than sticking it to a side wall. This is particularly relevant when you have carried out a mapping study and determined the ideal location for the sensor. In that case, make sure that the sensor does not interfere with loading and unloading your product(s) and that the location does not represent a risk for either your product(s) or the sensor.

Appendix - Troubleshooting Appendix - Troubleshooting If you are having difficulties with your configuration, look at these frequently asked questions before contacting technical support. There is nothing displayed on the EDGE module screen. What should I do? First, check to make sure the battery is installed and that it is inserted in the right direction (+/- according to the image in the battery slot). Try testing the unit with a battery that is known to be of the correct size and voltage (3.6V Lithium, 3600 mA). Contact technical support if the battery is OK and still nothing is displayed on the screen. I press the button for 3 seconds but my EDGE W-200 module does not connect to my receiver; what should I do? If your module displays “ACK_NOT_RECEIVED” instead of “ACK_RECEIVED” when you press the button, try bringing the module closer to your receiver for a better wireless connection. Also, check to make sure the receiver is working properly. The EDGE module is properly connected to the Cloud. Why don’t I get any temperature readings? This is usually due to a loose cable or improperly connected temperature sensor. Check the cable between the EDGE module and the sensor. Unplug the sensor and plug it back in. Make sure there are no exposed wires. Try a different sensor. Can external sensors be submerged in glycol? Yes, for all metal-tipped sensors, but not the dual temperature/humidity sensor (with the white Teflon/PTFE casing). To “absorb” sudden variations in temperature, such as those caused by opening and closing the chamber door, you may submerge the metal part of the sensor in glycol or glycerol. This limits inconsequential temperature variations recorded by the sensor. Check your laboratory’s Quality guide for recommendations and make sure to use a volume of glycol that corresponds to the volume of product(s) you are monitoring. To achieve the same results, you may also delay the transmission of alarms via the software and leave the sensors exposed. Temptime LoRaWan enabled solution EDGE W-200 module Page 28...
