TRACKER IS SLOW TO WAKE UP
1. Check that your tracker is getting full, early morning sun shining underneath the
framework. The wake-up fin (under the west-side canister) must see the sun.
2. Check that modules and electrical components are balanced over the center axle.
3. Check that bearings are lubricated and move easily.
NOTE:
If the Track Rack™ is
installed in a corrosive climate, check the axle and bearings frequently for rust /
corrosion.
4. The shock/s may be sticking when collapsed or extended. Remove the shock bolt at
the Bearing Plate and check the shock motion for “stick”. If the tracker wakes-up
without the shocks, they may be defective.
IMPORTANT:
Do not leave the tracker
defenseless without shocks – a strong wind could easily damage it. The rack can
easily be tied down by using customer-supplied tie-downs or ratchet straps.

TRACKER DOES NOT HIT THE BUMPER STOPS
1. Trackers are very effective even if they don't track all the way to the bumper stop. The
bumper stops are set for approximately 90° of rotation.
2. To increase the amount of rotation, raise the counterweight.
NOTE:
Raising the
counterweight also makes the tracker slightly less stable in wind. For optimum tracking
and stability, the Cross Arm should be only be resting lightly on the bumper bolt at the
beginning and ending of the day. If the tracker rotates further to one side than the
other, this may indicate that it is imbalanced left to right. This can be fixed by making
small adjustments to the position of the mounting rails / modules.

GENERAL SUMMARY
1. For proper performance, trackers must be assembled correctly.
2. The Track Rack™ should rotate smoothly throughout the entire range, with the only
drag supplied by the shock absorbers. If friction or interference is noted, check
assembly against instructions and make required corrections.
3. Photovoltaic modules should be mounted as shown in the module layout diagram and
as described in the instructions. Balance is critical!
4. There must be a minimum of 2” from the edge of the solar module to the Canister.
Insufficient space will interfere with tracking.
5. The Track Rack™ must be in a location that maintains a clear line-of-sight to the sun
throughout the day, and during different seasons. Shadows cast in the early-morning
light can significantly delay the wake-up time.
6. If high winds or severe storms are expected, securing the rack in a horizontal position
with straps is the best way to prevent damage.
7. Zomeworks Track Racks™ will move in the wind, much as trees do. This motion
is expected and does not harm the tracker or its performance. Unless a tracker is
blown far off the sun and stays there, the output is hardly affected. Overall, Track
Racks™ far exceed the performance of a fixed array.
