depress "Set" key, "A1" is displayed; at the right of "A1" a
numeric value for the automatic parameter appears, e.g. 35
(refer to Chapter 6.3). This value may be changed with the
arrow keys between 20 (sensitive) and 50 (inert).
depress "Set" key, configuration is complete.
you may quit the configuration mode at whatever point with

7.2. Manual mode
In manual mode, a manually defined nominal pressure is used. The following nominal profile may
be selected:
1: rapid decrease to nominal
2: ramp-shaped pressure decrease (refer to differential pressure and decrease interval)
3: end of cycle, vacuum valve closed, aeration valve open.
The following parameters may be set:
- nominal pressure, 1-999 mbar
- hysteresis (h), 1-100 mbar
- differential pressure, decrease:
Δ
p (d), 0-100 mbar
- decrease time:
Δ
t (t), toff (without) – 99 min
The "Set Vac" display is used for dialog display. All values may be edited with the arrow keys.
After not having done any editing for ten seconds, the item returns to "Actual".
Example:
The "Act Vac" display shows the nominal value to be set
(display flashing); for setting, use arrow keys.
The "Act Vac" display shows the hysteresis to be set, e.g.
h__5; this value may be adjusted with the arrow keys.
The "Act Vac" display shows differential pressure to be set,
e.g. d_45 which in turn may be edited with the arrow keys;
no differential pressure wanted, enter "0".
