Installation
1. Install the new cover gasket (53) (included in the
electronics cover kit). See F
IG
. 35, page 29.
2. Reconnect all wires.
3. Install the electronics cover (50) and tighten all 12
screws (20). Torque to 15-20 ft-lb (20-27 N•m). See
F
IG
. 30, page 28.
4. Install the new junction box gasket (8).
5. Route the fan cable through the fan cord grip.
6. Connect the stripped fan wire to the motor wire and
crimp the wires together.
7. Connect the fan ground wire. See F
IG
. 29, page 28.
See F
IG
. 26, page 27.
8. Use an adjustable wrench to tighten the fan cord
grip (C1). See F
IG
. 28, page 27.
9. Install the gasket (52), the junction box sleeve (101),
and tighten all four bolts (56). See F
IG
. 29, page 28.
10. Install the junction box cover (BA) and tighten the
two screws (6). See F
IG
. 25, page 27.
11. Install the wires into the disconnect switch (51) and
tighten the wire screws.
NOTE:
The lower must be removed from the system in
order to calibrate 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.
12. Connect the power cord.
13. Engage power.
Driver Motor Encoder Calibration
NOTE:
The driver must be de-coupled from the lower
and must be able to cycle freely with no obstructions.
1. Cycle power to the driver by first turning the discon
-
nect switch (K) 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 driver pressure
control knob (AK) 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 (Y) will run up and down
slowly over the course of several minutes.
5. Midway through the auto-calibration process, the
driver output shaft (Y) will pause as it moves to the
next step.
6. The driver output shaft (Y) 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.
