DETAILED PARAMETER DESCRIPTION<br />
P02 = 15 s (acceleration time)<br />
P03 = 80% UN (voltage step during deceleration)<br />
P04 = 15 s (deceleration time)<br />
P11 = OFF (Current Limit)<br />
P14 = 70% IN (switch undercurrent)<br />
P15 = 5s ( Undercurrent Time)<br />
P43 = OFF (By-pass relay)<br />
The other parameters continue with their previous values.<br />
NOTE!<br />
Although the values that are set automatically meet most<br />
applications, they can be improved to meet the requirements<br />
of your application.<br />
Please find below a procedure to improve the performance<br />
of the control of pumps.<br />
End setting of the pump control function:<br />
NOTE!<br />
This setting must be used only to improve the performance<br />
of the pump control and when the pump is already installed<br />
and able to operate at full-load.<br />
1. Set P45 (Pump control) at "On".<br />
2. Set P14 (undercurrent) or set P15 (Undercurrent Time) at<br />
"OFF" until the set has finished. After then, program it again.<br />
3. Check the correct direction of rotation of the motor, as<br />
indicated ON the pump frame.<br />
4. Set P01 (initial voltage - % UN) to the level so the motor<br />
starts to run without vibration.<br />
5. Set P02 (Acceleration Time [s]) to the starting time required<br />
by the load. With the manometer in the pipeline, check the<br />
pressure increase that must be continuous until the max.<br />
required level is reached without overshoots.<br />
If overshoots occur, increase the acceleration time to reduce<br />
this pressure overshoots at maximum.<br />
6. P03 (Voltage Fall Step - %UN) use this function to cause an<br />
immediate pressure drop or a more linear pressure drop<br />
during the motor deceleration.<br />
70<br />
7. P04 (deceleration time) during the motor deceleration<br />
check with manometer the pressure drop that must be<br />
continuous until the minimum level is reached without the<br />
presence of hydraulic ram when the non-return valve is<br />
closed. If this occurs, increase the deceleration time until the<br />
oscillations are reduced at maximum.<br />
