Caution
Upper limit values are specific to each range and measurement
mode. Be careful not to assume that the upper limit set in one
measurement mode will apply to the other.
For example, if you set 150 kPa as the upper limit in gauge
mode, the upper limit will not be 150 kPa in negative gauge
mode of the same range.
Note
Upper limits are always specified and displayed in the current
pressure unit except for altitude units. When in altitude units,
upper limits are expressed in kPa if the altitude unit is meters
(m) and psi if the altitude unit is feet (ft).
5.7.8.1.1
Over Pressure Function
In addition to the UL function, PPC4 has an over pressure function (see Section
3.2.21.1).
To recover from an overpressure condition, correct the overpressure condition
and cycle PPC4 power. Be sure to correct the condition that caused the
overpressure before cycling power.
5.7.8.2 Pressure Control
PURPOSE
To set the automated pressure control mode for the active range, customize
control parameters, activate default control parameters (see Section 3.2.2).
OPERATION
[Settings], <Control>, Pressure Control
opens the screen to select the control
mode and to set the control limits.
Select
Static
or
Dynamic
to change to that control mode and exit to the Main Run
Screen. The shortcut to
Pressure Control
is the
control mode
indicator on the
Main Run Screen (see Figure 11).
Select
[Limits]
from the Pressure Control screen to adjust or view the Control
Parameters.
Note
Control mode setting is range specific. A change in control
mode made while in one PPC3 range does NOT affect the
control mode setting in other ranges.
5.7.8.2.1
Custom Control Parameters (Limits)
PURPOSE
To view active pressure control parameters and/or set custom control parameters
(see 3.2.2).
OPERATION
To view active control parameters and/or set custom control parameters, use
[Settings], <Control>, Control Limits
from the Main Run Screen. Alternatively
