In many cases the value of products or cost of production loss represents great values. ClimaCheck do not assume any responsibility for injuries or costs occurring if failures are caused in connection with measurements. It is the user that must evaluate if an installation can be carried out without risks to cause injuries and/or damage.

Each Gateway unit has a unique id number to identify it on the ClimaCheck Online server, this number is set by ClimaCheck and can be seen in the display, on the second row, after the unit has booted up as “ID=XXXXXX”.
2 Communication The Gateway has LAN, Wifi, modem for Mobile connections and USB to communicate with the ClimaCheck server or a local PC. It has Modbus TCP and Modbus RTU and can be configured both as Server/Slave and Client/Master. 2.1 Ports The Gateway uses the following ports when communicating with the ClimaCheck Online server: •...
NX400. First option is USB Cable / WiFi and second option is Direct ethernet cable between computer and NX400, see Figure 4 and section 2.4 for more information on how to connect a PC. If no selection is made the unit activates Online Mode or PC Mode (USB Cable / WiFi) automatically depending on the default setting.
The Gateway can be setup to activate the modem and try to connect and establish a GPRS (Modem) connection with the ClimaCheck Online server if a SIM-card is inserted in the unit. If activated, this is done for both Connection Modes (Online and PC) and regardless of network interface settings except “No Network”, see section 3.11.

Press ESC 4 times to go back to the main menu or start from the top to connect another sensor. If “No new s-r found” appears while setting up a new sensor the NX400 cannot find any sensor on the bus that is not already configured, check connection and make sure the sensor has not been connected already.
NX400 has lost connection with the sensor, check wiring. 3.8 Reboot and Reload Configuration Most of the configuration for external units can be done on the ClimaCheck server. Changes to Modbus addresses for external units such as energy meters or R560 modules can be done on the ClimaCheck Online server and then downloaded to the unit.
• Press ESC until the start screen shows A PC can now connect to the NX400 and log data over WiFi simultaneously as data is sent to ClimaCheck Online. To deactivate the access point functionality again follow the steps below.
Data can be saved to a USB memory connected to the USB-port on the top side of the unit, see Figure 31. Data is saved with the same interval that is used to send data to the ClimaCheck Online server i.e. once every minute when the compressor is running and every 5 minutes when it’s off.
