8.8.1 Modifying the pressure bands

If desired, the operator can program two pressure bands (band 1 and band 2) with different pressure settings. The settings for band 1 are indicated as "Pressure Band 1 High" and "Pressure Band 1 Low", the settings for band 2 are indicated as " Pressure Band 2 High " and " Pressure Band 2 Low ".

Example:
For pressure band 1:
- Pressure Band 1 Low:		6.8 bar
- Pressure Band 1	High:	7.8 bar
For pressure band 2:
- Pressure Band 2	Low:	5.5 bar
- Pressure Band 2	High:	6.5 bar

Procedure

1. Consult the section above to select the parameter Pressure Band 1 High:

Pressure Band 1 High			7.8 bar	┤
Pressure Band 1	Low		6.8 bar
Pressure Band 2	High		6.5 bar	↓
Menu		Modify
F1		F2	F3

Fig. 8.11 Modify parameters menu

2.The screen shows that the current setting of Pressure Band 1 High is 7.8 bar(e). To modify this setting, press the key "Modify" (F2):

Pressure Band 1 High		7.8 bar
Program	Limits	Cancel
F1	F2	F3

Fig. 8.12 Modify parameters menu

3.The key "Limits" (F2) can be used to find the limitations for the parameter. Use the ↓ or ↑ arrow key to change the value.

4.Press the key "Program" (F1) to program the new setting or the key "Cancel" (F3) to cancel the modification operation.

5.The procedure to modify the Pressure Band 1 Low is similar to the description above.

6.If required, repeat the procedure for the Pressure Band 2 High and Pressure Band 2 Low (pressure band 2).
