19 Tighten the hex screw on the locking collar.
20 Toggle the valve between Load and Inject once again.
For the next few cycles the valve will operate at half its normal speed (noted
by a long, low pitch sound emitted as the actuator moves) while the “smart”
electronics locates the internal valve stops. Once it determines the proper
stroke, the actuator will return to normal speed (when the valve is fully
“trained,” the sound emitted will be short "chirps" of a higher pitch).
NOTE
Error messages might pop up while trying to home the valve. The first couple
are normal. If the errors continue, make sure the locking collar is fully
tightened.
21 Return the valve/pump module to its operating position.
22 Reconnect all tubing.
23 Check for leaks using the Xpress Config Tool to “Manual Cycle” the system.
