Similarly, if you had entered a Location, the Asset field would be read-only. When creating a Tag Out record Location and Asset fields are mutually exclusive, if you enter an Asset, 11430 in this case, then the Location field becomes read-only. More or assets and an asset/location can have multiple Tag Out sequences defined for it. The second point is that they are defined against locations A physical place where assets exist and where work can be performed. The first thing to recognise in the Lock Out / Tag Out application is that these records are defined at the Site A structural element of a Maximo database that is used for data separation. Following our review of the Lock Out / Tag Out application we will see how Hazards, Precautions, Hazardous Materials and these Lock Out / Tag Out rules come together when you build a Safety Plan. The Safety module is a sub-module of the Planning module. In the first part we examined Hazards and Precautions. Initialize the LCD library with I2C address and LCD sizeĪdc_voltage = (adc_value * ref_voltage) / 1024.This is the second part in a series of five articles that will provide a deep dive into the Safety module of core Maximo. Floats for resistor values in divider (in ohms) Floats for ADC voltage & Input voltage measuring DC Voltage using Arduino and voltage sensor up to 25Volts Not only Arduino UNO microcontroller but also you can use Arduino NANO, etc., The communication pins SDA and SCL are connected to A4 and A5 of Arduino respectively. The power pins VCC and GND of LCD display are connected to 5V and GND of Arduino. The LCD display has 4 pins 2 pins for power and 2 pins for communication. On the other side the voltage to be measured whose +ve and -ve pins are connected to VCC and GND respectively. The – pin of sensor is connected to GND pin of Arduino. Circuit Diagram to interface voltage sensor with ArduinoĬonnect all the required components according to the below circuit diagram.Īs you can see from the above circuit diagram the voltage detection sensor module signal pin S is connected to Analog pin A0 of Arduino. Follow the below schematic diagram to build own voltage sensor with range 0-25V DC.Īs you can see from the above 2 resistors are connected in series and signal pin is connected between them. This circuit reduces the voltage by 5 times. we can even build the circuit by our own with a very few components as 2 resistors 7.5KΩ and 30KΩ.
