PUMP_ENERGY_CALC¶
Function Block PUMP_ENERGY_CALC
| Available as of PLC runtime system | V1.3 and above |
| Included in library | PUMP_AC500_V23.lib |
| Type | Function Block without historical values. |
This Function Block calculates energy consumed by direct on line pumps and drive connected pumps. This is then used to calculate saved energy by using drives. Based on energy saved the CO:sub:2 emission reductions and money saved is also computed.
It also calculates efficiency of total flow (= volume) per total power (energy) in m:sup:3/kWh. Instant, hourly and 24 hourly (daily) efficiency are calculated continuously.
Total volume and total energy is calculated and connected as in or out parameter to the Function Block.
Note
This Function Block must be called cyclically with the cycle time of 50 ms in the task configuration.
Note
To retain this data, global retain variables need to be connected in the user program.
