3. Set Flow Control Override to % Open. See F
IG
. 79
and Table 10. On the Manual Override Screen, the
Flow Set Point field will display as a percentage
open (see F
IG
. 80).
NOTE: Set the Flow Control Override to “Pressure” to
use the Pressure Flow Control Mode (see page 77).
4. On the Manual Override Screen, drive the regula-
tor to a percentage open that starts fluid flow. Fluid
pressure should be above 12 psi (.08 MPa, 0.84
bar) [see the Status Screen]. Observe the fluid flow
rate at this pressure. This is the achievable low end
flow rate for the system’s given restriction. If a lower
flow rate is required, increase the restriction
between the flow control regulator and the spray
gun.
NOTE: If the lowest flow rate achieved is well below 12
psi (.08 MPa, 0.84 bar), add restriction to achieve fluid
pressure closer to 12 psi. Pressures below 12 psi can
be inconsistent.
5. Drive the regulator to 100% open. This is the maxi-
mum achievable flow rate based on the low flow
requirement and the flow control module’s functional
range.
6. When an acceptable operating range is achieved,
turn Flow Control Override Off.
7. Run Flow Control Calibration, page 74.
