Table of Test Instructions
**Flash the test code firmware before testing the device. Follow the instructions given in the Guide to Flash the Test Code Firmware guide, to flash the binary code.
| Testing component/feature | Test | Expected Output/Outputs |
| Power | Provide 24V DC supply. | Red colour LED inside the device glows. Display turns on. |
| Display | Power-up the device using USB cable or 24V DC supply. | Display starts with the Norvi logo. Device model is displayed. Final screen with Input, Output and Push Button status appears. The output side LED indicators glow in a pattern. |
| Digital Inputs | Power-up the device using 24V DC supply. Connect the GND & COM pins and supply the 24V DC to every digital input one by one. | Refer to the expected outputs of the Display Check above. In the input status, status of all the 8 digital inputs will be 1.(As the inputs are internally pulled up) The input status changes from 1 to 0, and the input side LED indicator starts to glow accordingly. |
| Voltage Inputsand Transistor Outputs | Power-up the device using 24V DC supply. | Status of all the 6 analog inputs will be 0. Toggling output status (from 0 to 1 ) is observed on the display for the 2 transistor outputs, which follows the output side LED indicator blinking pattern.Whenever these LEDs are on, it means the respective transistor is on. |
| Voltage Inputsand Transistor Outputs (continued..) | After powering up the device, to check the working of the 6 analog (voltage) inputs, supply a voltage between 0-10V (10V max) to each voltage input. (Check this link for the wire connection) To check the working of the 2 transistors, a voltage test is done using a multimeter.To do this, keep the positive probe of the multimeter on the +24V pin of the device. Next touch the negative probe with the 2 transistor output pins after,one by one after a 15s gap. | On the display, the voltage sensed by the Norvi device is displayed.(You can confirm these voltage values using a multimeter.) The multimeter shows a 24V DC reading, whenever the transistor is on.(Transistor status is indicated by the respective output side LED indicator and the output status on the display) |
| Push Buttons | Press the 3 push buttons, one at a time. | The 4 digit analog status of the push button is displayed accordingly on the display. ***Analog status 1_ _ _ for the upper button Analog status 2_ _ _ for the middle button Analog status 3_ _ _ for the lower button |
| RS-485 Communication | For this test, a USB to RS-485 converter is required. Connect the RS-485 A and B pins of the Norvi device with the respective A and B pins of the USB to RS-485 converter. Plug the USB end of the USB to RS-485 converter to the PC. Power-up the Norvi device using USB Cable. Open the Arduino IDE application. Select the correct COM port of the USB to RS-485 converter in Arduino IDE and open the serial Monitor. Send the Number ‘5’ in the serial monitor. | In the serial monitor “RS485 SUCCESS” statement getting printed is observed. This indicates that the RS-485’s Tx operation is working properly in the Norvi device. Once number “5” is received, all the output side LED indicators will glow simultaneously for a few seconds. Then later they’ll continue to glow in their previous pattern. This indicates that the RS-485’s RX operation is working properly in the Norvi device. |
