User Responsibilities
The performance, reliability and safety of your heat-tracing system depend on proper design, selection, and installation. The Elexant Connect application will help you to configure and monitor a system that meets your requirements, but it is only a tool. It assumes that your input is accurate, that you are familiar with heat-tracing system design and configuration, and that you will ensure that all components of the heat-tracing system are installed, maintained and used as intended. The configuration of the controller should be reviewed by a knowledgeable engineer to ensure it is appropriate for your application. Additional information relating to safety, design, and installation is contained in Design Guides, Installation Manuals, Data Sheets, and other literature available from nVent . Be sure to consult these documents as needed.

Safety Warnings
There are important safety warnings which are shipped with nVent products. Be sure to read, understand and follow these safety warnings to reduce the risk of fire, shock, or personal injury. If you have any questions, contact your local representative or contact nVent directly. Warning, Error, and Alarm Messages Under certain conditions, the Elexant Connect application will alert the user with a warning, an alarm, or an error message. These are typically either because the program cannot find an acceptable answer based on user input, or because the user may need to take some additional action to ensure the design requirements are completely met.
For questions, please contact your local representative, or contact nVent directly

Scanning for Nearby Devices
The way you can connect to either an Elexant 3500i, Elexant 5010i, or NGC-20 is by first scanning for devices by clicking the Bluetooth Button on the top right of the Main Screen. This will scan for all available nVent Controllers which might take a while depending on how many you have (Fig.7). Before scanning, you can filter out what device you want to see with the Device Type drop down menu. When scanning, 2 things will show up on the screen after a device has been scanned. The Device Type (NGC-20, Elexant 3500i, or Elexant 5010i) and The Mac Address for that device.

Fetching Data from Scanned Devices
After the Scanning process is done, it will start fetching data for the controllers shown on the screen one by one. When fetching data is complete, the Screen will look like (Fig.8). It will fetch the Device Tag and the Firmware Version. If the device has Bluetooth Security (Section 4.1.1.2) enabled, a locked symbol will be shown beside the Tag.
When Scanning, if you recognize the Mac Address to the device you want to connect to, you can click stop scanning, which will prompt the app to start fetching the data for the devices already scanned. You can also skip the Fetching process by clicking cancel, no Tag or the Firmware Version will be shown, but you can still connect to a device when clicked.

SCREEN LAYOUT

Top Section Screen
Each screen will show the same header information, which looks as follows. You can slide the Tab Section to see the rest of the tabs. Please note that not all settings will be available depending on which controller the Elexant Connect Application is connecting to.

Password Reset Code
If you have forgotten your password, you can request to reset your password. This will generate a key (Fig.15) which you will have to send to nVent Customer Support who will in return give you a code which will reset your security on your device. Reset Code List (Fig.16), which is shown in the Main Screen (Fig.3) will display the reset codes for your devices that you requested for. These keys will only last 48 hours, where, 24 hours after the first key was generated, a new one will be generated if you request again.

Controller Tabs
All information of the controller is displayed in separate displays. The user can select different screens for detailed overviews. The selections are

OVERVIEW SCREEN

The main overview screens shows the most common, most used parameters of the Elexant 3500i, Elexant 5010i, and NGC-20 controllers. This overview will enable the user to have a quick overview of the controller.
The top section describes the Modbus address of the controller, the name, firmware version in the controller, the output status and the number of alarms in the unit.
The Control section gives a quick overview of the control mode, measured temperature, setpoint and temperature alarms.
The measured current, low and high current alarms as power consumption are presented in the Current section.
Ground fault information is presented below. Ground fault can be alarmed upon and/or trip the controller, depending upon customer requirements.

ALARM SCREEN

The alarm screen shows all alarms present in the controller. The alarms can be reset one by one (Reset Selected), or all by once (Reset All).

The alarm message describes

Time Stamp
- The time on which the Android App has read that there is an alarm. It is not when the Alarm had occurred
The Alarm Type
The Alarm Value
- If the Alarm has an associated Setpoint value for it, the value that would be shown is value that raised the Alarm

TEMPERATURE SCREEN

The temperature screen presents all data available in the controller related to the temperature control.

The top section presents

Control Temperature based on what Control Temperature Mode was selected (lowest, average or selected source),
Temperature on which the Heater was last on,
Temperature sensor 1,
Temperature sensor 2,
Temperature source 1 (the input to the controller – under normal conditions this is sensor 1)
Temperature source 2 (the input to the controller – under normal conditions this is sensor 2)

By clicking on the horizontal bar underneath Source 1 / Source 2 more source options become available. These are not used with the current version of the Elexant 3500i, Elexant 5010i, or NGC-20 software but are available for potential future extensions.

The bottom section of the temperature page consists of a horizontal sliding bar. These tabs allow the user to view all details on

Control
Sensor 1
Sensor 2
Source info

Temperature – Control Screen

Setpoint
The temperature on which it switches the controller on or off.

Mode

Lowest: Setting the Temperature Control to Lowest means that the output of the controller will be controlled based on the lowest temperature measured by any of the temperature sensors connected to the controller
Average: Setting the Temperature Control to Average means that the output of the controller will be controlled based on the average temperature measured by all the Temperature sensors connected to the controller.
Sources: Setting the Temperature Control to a Source means that the output of the controller will be controlled based on the temperature measured by that source. There are 1 to 8 different sources to pick from

Fail Mode

Fail Off: when the control sensor(s) of the controller fail the output switch will open.
Fail On: when control sensor(s) of the controller fail the output switch will be permanently close.
Last %: this Fail Mode is only applicable to the control mode PASC or Proportional Ambient sensing. It will control the output in a similar manner as it was doing before the sensor(s) failed. This Alternate ON/OFF switching will be time based only – there will be no relation to temperature.
Fixed %: it will alternate the control output ON and OFF at a certain interval.

High Limit Cutout
The High Limit Cut-Out function prevents the heated surface from overheating. When the High Cut-Out Temperature Set Point is reached the controller output will be turned OFF regardless of whether or not the maintain temperature is reached. Use this function for instance to prevent the cable surface temperature exceeding a certain level. It can be configured to operate as either a latching or non-latching type. When the Latching button is set to YES than each time an alarm has occurred the Alarm needs to be manually reset. When set to NO then the alarms will be self-healing and will disappear when the alarm condition is no longer present.
The high limit cutout does not need to be reset for normal operation of the controller. Once the conditions are healthy again, the controller will work based on the temperature setpoint.

Low Limit Cutout
The Low Limit Cut-Out function gives the user control of the heater by allowing it to be active in a certain range. When the temperature goes below the Low Limit Cut-Out temperature, the controller output will be turned OFF regardless of whether or not the maintain temperature is reached. It can be configured to operate as either a latching or non-latching type. When the Latching button is set to YES than each time an alarm has occurred the Alarm needs to be manually reset. When set to NO then the alarms will be self-healing and will disappear when the alarm condition is no longer present. The Low limit Cut-Out Alarm does not need to be reset for normal operation of the controller. Once the conditions are healthy again, the controller will work based on the temperature setpoint. You can set a Deadband value for Low limit Cut-Out, if the temperature is less than “Low Limit Cutout Setpoint – Deadband Value”, the alarm will be raised.

LIMITER SCREEN

This section in the Elexant Connect application describes how to configure the SIL2 approved Safety Temperature Limiter in the Elexant 5010i-LIM and NGC-20-CL-E controller. The purpose of the limiter is to prevent heating applications from overheating. The Safety Temperature Limiter is approved for use in Hazardous area Zone 1, Zone 21, Zone 2 and Zone 22.

Firmware
This field shows the actual firmware revision of the Safety Temperature Limiter.

Safety Limiter Status
This field shows the actual status of the Safety Temperature Limiter.(Normal operation, Tripped, Latch Temporarily Disabled)

Safety Limiter Temperature
Shows the temperature actually being measured by the Limiter RTD. If this value surpasses the Safety Limiter Set Point the Safety Limiter will trip open. Once the Safety Limiter has tripped a manual intervention will be required to Reset / Rearm the Safety Temperature Limiter. Resetting the safety Temperature limiter will be only possible after all process conditions have returned to a safe state. (The Limiter Temperature has dropped below the Limiter Temperature Set Point.

Safety Limiter Temperature Set Point
This field holds the Safety Limiter Set Point. This value should be chosen in accordance with the Temperature Class of the area in which the heating application is installed (T-class T4, T3, T2) or the maximum surface temperature allowed for the heating device assuming this is a lower temperature. Since the Safety Temperature Limiter is a safety device it requires a special procedure to write a new set point to the Temperature limiter. Tap in the Limiter Temperature Set Point field to start the write procedure. This will open a new screen.

Note: When using Fahrenheit, temperatures may be off by one degree.

From this point onward the Elexant Connect app device will send the new set point at regular intervals to the controllers (Polling). The polling process will be repeated until the process is cancelled or until the Safety Limiter Set button inside the unit is pressed. Press and hold the button for 3 seconds. The Display of the controller will flash briefly and show actual and new limiter cut out temperature. The Safety Limiter Temperature Set button is the Black Push button on the left-hand side of the Elexant 5010i-LIM hardware as is shown on Figure xx below. After the new set point has been successfully updated a message will appear confirming the new set point has been successfully updated.
