Step
Prior to stowing, verify the Lightband is in the allowable temperature range per
8.2.11
Section 4, Note 9.
Prepare to stow the Lightband. See Figure 8-8 and Table 8-1 for the
anticipated current draw and power duration.
Verify the oscilloscope trigger is active and ready to acquire data.
8.2.12
When ready activate the timer relay to stow the Lightband.
Manually cut power if the current limit is reached or the timer relay runs longer
than specified and contact PSC immediately. A visual inspection of the
Lightband may be performed, but do not change configuration.
De-activate the power supply output.
8.2.13
Save the voltage and current profiles for both motors and verify the data is
8.2.14
readable.
Figure 8-8 shows example stow voltage and current profiles. Complete Table
8-1 to verify all parameters are within tolerance. Single data point exceedances
are acceptable. Also, a slow sample rate may alias data. Do not filter data.
Contact PSC if a discrepancy is found.
8.2.15
Remember to account for non-zero offsets in the voltage or current
measurements.
Figure 14-1 shows the post-stow state of the switches in the Motor Bracket
Assembly. Measure resistance directly at the Lightband's DB-9 socket
8.2.16
connector and complete Table 14-1. See Figure 16-2. Contact PSC if a
discrepancy is found.
If weights or a fixture were used to compress the Lightband, they may be
8.2.17
removed at this time. If LCTs were used remove cable ties per section 18.5.
