Make sure wires are not pinched when re-installing
covers. Wires will be damaged and create an
electrical hazard and/or fire and explosion hazard
if pinched.
1. Plug in all connectors. Ensure all connectors
are securely attached to the control board. See
Wiring Schematic, page 26 .
2. Secure loose motor wires into the clip inside the
housing (see
Wiring Schematic, page 26 ).
3. Reinstall electronics cover onto center housing.

Power Power Power Unit Unit Unit — — — Run Run Run Calibration Calibration Calibration Procedure Procedure Procedure
NOTE: NOTE: NOTE: The driver must be de-coupled from the
pump lower and must be able to cycle freely with no
obstructions.
1. Cycle power to the driver by first turning the
power switch (S) OFF, and then ON again.
2. Wait for the status indicator LED (L) to turn on
solid or start blinking.
3. Within 30 seconds, rapidly turn the pressure
control knob (N) back and forth from 0 to 10 at
least five times and then set the knob back to 0.
If the status indicator LED (L) was solid before,
it will begin blinking an encoder calibration error
(code 8) during the calibration process.
4. The driver output shaft (H) will run up and down
slowly over the course of several minutes.
5. Midway through the auto-calibration process the
driver output shaft (H) will pause as it moves to
the next step.
6. The driver output shaft (H) will move up and
down faster 5–6 times.
7. Ensure the auto-calibration process is complete
before continuing (wait for the LED to stop
blinking).
