SkyTracker STX-1-2000 - 3 Operation of the Sky-Tracker; Input Power Requirements; Startup and Shutdown

As is the case with all intense light sources, it is not advisable to look directly into the light
source or into the light beam. It is the responsibility of the operator to see that the neces-
sary rope barriers or other barricades are positioned suitably to prevent passers-by or any
member of the crowd from looking directly into the light beams from a close distance.
3.0 OPERATION OF THE SKY-TRACKER
3.1 INPUT POWER REQUIREMENTS
CAUTION
Each SkyTracker model has been designed and factory tested to operate
satisfactorilywithaninputpowersourceasspeciedbelow.TheDClamp
power supplies, incorporated within each SkyTracker base assembly, can
be adjusted to compensate for input voltages which are slightly lower or
higher than nominal. Details of this adjustment procedure may be found in
section 4.5.2 of this manual. It is the responsibility of the owner/operator to
determine that proper input power is provided and to make adjustments or
corrections as may be required to provide compliance with the requirements
set forth below.
CAUTION
Polarity and grounds must be checked before cable connections are made to
the SkyTracker. Low voltage conditions (less than the minimum levels speci-
edbelow)maycausedamagetotheSkyTracker.
Use 100’ (30.5 m) or shorter cables. For cables longer than 100’ (30.5 m), go to larger wire sizes.
*Recommendedwiresizes;conform to local codes
3.2 STARTUP AND SHUTDOWN
The operation of the SkyTracker controls will be explained in this section. The SkyTracker
control panel (see Figures 2 & 3) is protected from weather, vandalism, and unauthorized
access by means of a locking cover panel (STX-4 models only). The STX-1 control panel
is enclosed by a screw cover.
When the input power supply cord is connected and the circuit activated, the green pilot
lights(identiedas“InputPower”)willlightandremainlitsolongasallinputphasesareon.
