10.4.5
PSC recommends recording video and audio of the Deploy operation. This is
not required but has proven very helpful in determining root cause in the
unexpected event of an anomaly.
-----N/A-----
10.4.6
To Deploy the Lightband:
1. See Figure 10-5 and Table 10-1 for the anticipated current draw and
power duration.
2. If a force was applied per step 10.4.1 the Upper Ring will not move. This
force will be removed at a later step, allowing the Separation Springs to
extend.
3. Designate a person to watch the power source output display.
4. Turn on the power source output.
5. Verify the oscilloscope trigger is active and ready to acquire data.
6. Activate the timer relay. This will send power to the motors and Deploy
the Lightband. The Lightband should Deploy in
≤ 0.1 s and the Deploy
limit switches on the Motor Bracket Assembly will automatically cut
power to the motors.
Manually cut power if the current limit is reached or the timer relay runs longer
than specified. Then contact PSC per section 4. A visual inspection of the
Lightband may be performed, but do not change configuration.
10.4.7
Take a picture of the oscilloscope screen in case data inadvertently gets
erased.
10.4.8
Turn off the power source output.
10.4.9
Save the voltage and current profiles for both motors and verify the data is
readable.
10.4.10
Figure 10-5 shows example Deploy voltage and current profiles. Complete
Table 10-1 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 immediately if a discrepancy is found.
Remember to account for non-zero offsets in the voltage or current
measurements.
