Figure 77: p1 Pressure Band
Note that there is a certain limit that can be set for each of the pressure values. For example, the
Target
pressure minimum is 100 psi which is the Load Pressure Value. If you want to set the Target pressure
below 100 psi then the Load pressure needs to changed first and it should be set lower than the Target
pressure .
Similarly, the upper limit, max is 116 psi which is close to the
Unload pressure . If you want the Target
pressure greater than 116 psi then the Unload pressure needs to change first and its value should be
greater than the desired Load Pressure .
The same methodology will be followed for setting the
Unload and Warn pressure values.
We can toggle between the primary pressure and secondary pressure screen with the button available on
the bottom of the
Pressure Band Setting screen. The p1 Pressure Band screen has a button called View
p2 to jump to p2 pressure band screen.
4.2.3 p2 Pressure Band
The
p2 Pressure Band defines alternative pressure set points that can be activated by a timer or control
input. This band can be used for when the compressor is operating at off-hours or during the weekend
when production is not functioning at full output and therefore does not have the same pressure
requirements.
Similar to the primary pressure band settings, it has five parameters:
Load, Target, Unload, Warn, and
Fault . Any of these values can be changed by selecting the input boxes. A sample screen of p2 is shown
in Figure 78 below. The warning and fault setting on the p2 screen is the same set point as the set points
on the p1 pressure band settings screen.
