NOTICE
Calibration
NOTE: The lower must be removed from the driver in
order to calibrate the driver correctly. The calibration
stroke length is longer than the operating stroke.
Leaving the lower attached will cause the driver rod to
contact the lower rod and it will not calibrate correctly.
1. Cycle power to the driver by first turning the power
switch (S) to OFF, and then to 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.
-
The driver output shaft (H) will move up and
down slowly over the course of several minutes.
-
Midway through the auto-calibration process,
the driver output shaft (H) will pause as it moves
to the next step.
-
The driver output shaft (H) will move up and
down faster 5-6 times.
4. Ensure the auto-calibration process is complete
before continuing. Wait for the LED to stop blinking.
