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.
Flow Control Startup
1. Set Flow Control to “On: Setup” in Configure
Screen 5.
2. In Advanced Setup Screen 1, turn Manual Over-
ride “On: EK”. This sets the override control source
as the EasyKey. The Flow Control Override field will
appear. The other option, “On: Ext” is used for par-
tial control by a PLC robot.
3. Set Flow Control Override to % Open. See F
IG. 89
and Table 12. On the Manual Override Screen, the
Flow Set Point field will display as a percentage
open (see F
IG. 90).
NOTE: Set the Flow Control Override to “Pressure” to
use the Pressure Flow Control Mode (see page 88).
