Parameter settings
To optimize control performance, use the local HMI to enter parameter mode and adjust a number of control parameters. All control parameter settings are retained after power failure.
Proceed as follows to change the control parameters:
Or | ||
Press and hold the + and - buttons simultaneously for more than 3 seconds. | |
Service level: Release the buttons, and within 2 seconds, press and hold + until Pxx is displayed. | |
Press + or - (< or >) to access the desired parameter and the value of the selected parameter is displayed at the same time. | |
Press () to edit the value of the required parameter. | |
Press + or - to increase/decrease or select the value of the current parameter during editing. | |
Press () to confirm the new value or press () to cancel the change, and repeat steps 3 to 5 to change more parameters. | |
Press () to exit parameter setting mode. |
Reload factory setting
- Select parameter P89 and set it to 1.
- The factory settings of the control parameters are reloaded.
- “- - -” is displayed during reload.
