Danger to life!

Indicates possible property damage DANGER ATTENTION 3 System description The testo Saveris wireless sensors are part of the testo Saveris Solution. As a stationary measurement technology solution, they are ideally suited for monitoring temperature and door contacts in cold stores and warehouses. The wireless sensors are available in various versions and can therefore be flexibly adapted for numerous applications. Depending on the version, they have an air temperature sensor, an additional product simulator (mimicking), a door contact sensor and a penetration probe sensor. The data of the sensors is transmitted via a Gateway in to the Saveris Restaurant cloud. The sensors can be integrated into the testo Saveris Food Solution. The data is recorded at configurable intervals and transferred to the Testo Cloud [Cloud] at configurable intervals. The customer's WLAN or Ethernet infrastructure is a prerequisite for transmitting the data (not part of the scope of delivery). The measured values stored in the cloud can be called up and analyzed at any time in the corresponding testo Saveris Cockpit [Webbased analysis]. Limit value violations are immediately displayed on the Control Unit [Operative Control Unit]

This calculated value represents a product temperature value according a calculated/ simulated behavior. The product simulator is designed to simulate food thawing and chilled or frozen food. However, the product simulator does not represent the core temperature of the food, but simulates the behavior of the food. 3.5 radio data logger door contact This sensor is used to detected/observe open or closed doors. 3.6 radio data logger core temperature With this sensor it is possible to measure temperature of liquid food, i.e. soups. Just immerse the metal sensor tip inside the liquid food. 3.7 Gateway button functions & LED long = 1 sec / periode = 2 sec short = 200 msec / periode = 400msec Gateway LED1 Sensor status Mode Join Mode action /

> 30 sec 4 Commissioning This chapter describes the commissioning of the NSF test set up. The system is mainly designed to enable NSF to do the certification tests. The system does not support the whole system UI functionality, which will be offered to end customers in series. The hardware devices have already achieved nearly series level. The measurement data of the devices itself is sent to the original Cloud IoT-core, from where the data can be displayed via Saveris Restaurant Website. Additional the software MTS IoT Core viewer, allows the user to display the measurement values on PC and export the data to csv.file. This software is very limited in its functionality and has only the purpose to get measurement values from the IoT data base. The UI is simple and limited. Measurement and communication cycle is set default by system. Measurement cycle: 1min Communication cycle: 1min 4.1 Mounting on the wall The wall bracket is used to mount the online data logger. Select suitable mounting materials according to the desired mounting location. The wall mount can be attached using the supplied adhesive strips. Alternatively, suitable screws or cable ties can also be used (not included in the scope of delivery). DANGER Danger to life!

Electrical lines can be damaged.

- When fixing the wall bracket by means of screws, do not mount directly on electrical equipment. When using adhesive strips, make sure that the substrate is clean and free of grease. 4.2 Mounting of communication module to the Gateway 4.2.1 WLAN module and PoE module Before connecting the gateway to the PC or to power supply, the communication modules must be mounted to the gateway first. 4.2.2 Power supply / batteries In general, the Gateway runs without any batteries. It needs a continuous 5V DC/2A power supply. Additionally, the gateway has a battery compartment. Batteries are only relevant for customers, which follow a disaster recovery plan, to ensure, that in any case of power loss, that gateway still works. Basically, the gateway does not store any measurement values. If the power is down, measurement values are stored in the sensor, if they cant be forwarded to the gateway due to power loss. 4.3 Configuration of the Gateway In case of using WLAN, make sure that a stable WLAN connection is available before you start configuring the gateway, In case of using Ethernet, make sure that the Ethernet connection of the Gateway to the cloud is not blocked by internal fire walls of the IT. See chapter 7. 4.3.1 Account / Saveris Connect Key The Account ID/Saveris Connect Key is the unique address of your user account in the Testo cloud. This connect key is needed to configure the Gateway in order to ensure that the Gateway sends your data to the correct user account. 4.3.2 NSF-certification account The user account is defined by an email-address:

Account Saveris Connect Key / Account-ID testo.qsr+nsf.ws_rm@gmail.com DW-K4-LM-Q3-int0 Password is sent separately!

4.3.3 Gateway offline configuration The Gateway can be configured via a PDF form. Note You need the Adobe Reader program (version 10 or later) to use the PDF form correctly. If you have not installed Adobe Reader, you can go to the following address to download it free of charge: http://get.adobe.com/reader/. 1. Connect the Gateway with mounted WLAN module to the PC. 2. Open the file NetConf.pdf on the external drive in the Windows-Explorer. 3.Enter the Saveris Connect Key into the Account ID field 4. Enter the local WLAN Network name (SSID) and, if necessary, your WLAN password in the relevant fields on the PDF form. 5. Click on the Save configuration button. A dialogue box opens for exporting the form data. 6. Select the external Gateway drive as the storage location and save the form data (configuration file WiFiConf_Daten.xml) on it. 7. Disconnect the USB connection from the PC to complete the configuration of the logger. You can also save the configuration file locally on your computer and configure other Gateways even faster by simply copying the XML configuration file onto their external drive. 8. Connect the Gateway with USB-cable to external power adapter. Do not use the Laptop for power supply. 9. After powering up the Gateway again, the Gateway starts connection to the cloud. 1 2 3 4 5 7 8 4.4 Connecting a radio data logger Before you connect a radio data logger to Gateway, please ensure, that the Gateway is connected to the cloud. You can check the with Saveris Restaurant Website. See chapter 5!
