Graco 332564B Fluid Control, Manual Override, Gun Trigger Signal, Flow Control Setpoint Signal

Setup Mode Screens

System Screen 5

System screen 5 sets the following system operating parameters.

Figure 32 System Screen 5

Fluid Control

Select the desired operating mode (pressure or flow), using the pull-down menu.

•In Pressure Mode, the motor will adjust the pump speed to maintain the fluid pressure set by an external control device.

•In Flow Mode, the motor will maintain a constant speed to maintain the target flow rate set by an external control device.

Manual Override

Check this box to give users system control at the ADM. Leave the box unchecked if all system settings

are controlled through a PC, PLC, or other networked device.

Gun Trigger Signal

Select the format of the signal indicating whether the spray device is triggered.

•Discrete — the signal is sent via a direct, hard-wired connection

•Network — the signal is sent via a PC, PLC, or other networked device.

Flow Control (Setpoint Signal)

Select the format of the signal that indicates system flow rate or pressure.

•Discrete — the signal is sent via a direct, hard-wired connection. This selection will make the Max Rate field active.

•Network — the signal is sent via a PC, PLC, or other networked device.

Stepup Gain and Stepdown Gain

These fields are active only for systems set to flow control on System Screen 5. Enter a value from 1 to 100 to optimize system response time to a change in fluid flow setpoint. Use the Stepup Gain field for increases in fluid flow setpoint. Use the Stepdown Gain field for decreases in fluid flow setpoint.
