Hitachi HISCREW 2000 Series - 3.4 Setting of the Control Functions

12
3.4.1 Setting of Capacity Control Mode
As listed in the table below:
・ The S- and M-type As provide two ca-
pacity control modes each.
・ You can select either one of them by setting the
No. 3 & 4 pins of the DIP switch SW2 located
on the printed circuit board.
3. HOW TO OPERATE [Setting of the Control Functions]
3.4 Setting of the Control Functions
When you use an external air dryer under the ‘A’ mode
of capacity control (U-type + I-type + P-type), enable it
to keep operating even when the A automati-
cally stops. Thus protect the external air dryer from stop-
ping and restating frequently.
For more information on the capacity control sys-
tem, see pages 29 through 30.
IMPORTANT
Do not select the U-type when your A specifies
the discharge of 0.92 MPa.
IMPORTANT
NOTES:
1. The shaded cells indicate a standard factory setting.
2. The + mark indicates that the CPU automatically selects
either of the 2 or 3 capacity control types whichever is
appropriate.
3. Do not set the SW2 No. 3 & 4 to other than the above.
