5. The DCU-1 display should look similar to the
display shown in Figure 4. The numeric
display in the lower left corner indicates the
current bearing of your rotator. The numeric
display in the lower right corner indicates the
target bearing. If both displays read a steady
"000", disconnect your control cable and
check the cable wiring with an ohmmeter. See
Section 9, "Checking the Rotator Resistances
from the Ground". Proceed if the cable checks
OK.
NOTE: After approximately 30 seconds of inac-
tivity, the target digital and analog displays will
blank (disappear). After 30 minutes of inactivity,
the entire display will blank. Push the
"DISPLAY" button to return normal dis
la
.
6. If the current bearing display shows a number
between "000" and "359", then proceed. Twist
the knob marked with the two (2) arrows
"(o)". The target bearing display should
change along with the inner circle tick mark.
Using the knob, select a target bearing at least
30 degrees from the current bearing. Push the
"START" button. The brake in the rotator
should release, the rotator will turn a few
degrees in the opposite direction, reverse
direction, then turn to the target bearing.
During the last 5 degrees, the rotator will slow
down to half speed, then stop on or close to
the target bearing. The brake solenoid will
"hum" for 8 seconds, then the brake will
engage. During rotation, the outer circle tick
mark will move to the new bearing. If
operation does not work as described,
immediately unplug the unit from the AC line
and check cable wiring!
7. You may wish to repeat step 6 to confirm
operation over a wide range of bearings. If the
"STOP" button is depressed during rotation,
rotation will stop and the brake will engage 8
seconds later. If the operation is consistent,
roceed to the next ste
