Flow Control Setup; Flow Control Startup - Graco ProControl 1KS Operation

Flow Control Setup

1. Install the intrinsically safe flow regulator (FC) as
explained in the ProControl 1KS Installation Manual.
2. Ensure that the analog signal is 0-10 Vdc, or is
properly provided through network communication.
3. Calibrate the system's flow meters; see page 102.
This ensures that the K-factors are tuned to the
range of materials being used.
4. Verify that the I/O inputs are working properly. If
using discrete I/O, check by viewing Advanced
Setup Screen 6 and Advanced Setup Screen 7,
page 38. If using network communication, ensure
the commands are being sent by viewing the Status
Screen, page 21, and Advanced Setup Screen 6
and Advanced Setup Screen 7, page 38, for
inputs.
NOTE: See the Graco Gateway manual for Flow Control
Modbus addresses.
5. See Flow Control Startup.
