Graco 3A2098H important safety instructions Adjust Pressure Sensors, Configure Errors

System Setup

Adjust Pressure Sensors

Set pressure offsets and pressure limits.

NOTE: Inlet sensor settings will be grayed out on this screen for systems with heated fluid plates.

1.With the system in setup mode, navigate to the Fluid Plate x, screen 5 (Pressure Sensors).

2.Press to access the fields to make changes.

FIG. 24

NOTE: For the following steps, press and

to navigate through each field, and to open drop-down menus and enter changes or selections.

3.Set the desired offset for the inlet and outlet pres- sures between 0 and 100 psi (0.7 MPa, 7.0 bar). Remove all pressure on the sensors, and then adjust the offset so the measured value reads 0.

NOTE: It is recommended that offsets should not be changed from the factory defaults of 0.

4.Set the desired minimum and maximum pressure limits for the inlet, and the desired maximum pres- sure limit for the outlet.

5.Set the error type (alarm or deviation) that will be issued:

•If the minimum inlet pressure decreases below the setting.

•If the maximum inlet pressure increases above the setting.

•If the maximum outlet pressure increases above the setting.

6.Press to exit edit mode.

Configure Errors

Set the error type (alarm, deviation, or none) that will be issued if the pressure, flow rate, volume, or computed target goes outside the tolerance settings of the active style. When an alarm occurs, the system stops dispens- ing. When a deviation occurs, the system will continue dispensing. See Fluid Plate x, Screen 6 (Error Type) on page 107 for more information.

NOTE: Only the low/high pressure errors will be enabled for systems without a flow meter.

1.With the system in setup mode, navigate to Fluid Plate x, screen 6 (Error Type).

2.Press to access the fields to make changes.

3.Press to open the Low Pressure drop-down list, and select either Alarm or Deviation for the error

type. Press to enter the selection.

4.Press to move to the next field. Repeat Step 4 for each field.

5.Press to exit edit mode.
