Automation of processes in the installation of closed water supply

Offering extra earnings. On the basis of OVIEN PLC110.30.R-MS4-3 and the MU-110 8A analog input module, it is required to automate processes in the closed water supply installation.

Functions
1. Maintaining a predetermined level of dissolved oxygen (hereinafter O2)
- the ability to set maximum and minimum levels of O2
- obtaining data from the O2 sensor
- ability to calibrate the sensor value (input the current value obtained when measured by the reference instrument)
- obtaining data from the temperature sensor
- correction of the value of O2 depending on temperature
- rotation of the proportional valve of oxygen supply (at a minimum to open, at a maximum to close, at a value between leave as is)
- the possibility of changing the step of rotation of the proportional valve
- to take the next measurement after a time interval (delayed system response)
- Ability to change the time period

2. Maintenance of a predetermined level of redox potential (hereinafter - ORP)
- the ability to set maximum and minimum levels of AFP
- obtaining data from the ORP sensor
- ability to calibrate the sensor value (input the current value obtained when measured by the reference instrument)
- the transmission of a control signal when the minimum level of AFP is reached
- termination of the control signal when the maximum level of AFP is reached

3. Maintaining a predetermined Ph level
The ability to set maximum and minimum levels of Ph
- obtaining data from the sensor Ph
- ability to calibrate the sensor value (input the current value obtained when measured by the reference instrument)
- the transmission of a control signal when the minimum level of Ph is reached
- Stopping the control signal when the maximum level of Ph is reached
