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).
