Deploying The Lightband - PSC 2000781J MkII MLB Operating Procedure

10. Deploying the Lightband

Step
Oscilloscope shall record voltage and current per the following requirements:
10.1.1
1. Sample rate: 1,000 Hz minimum
2. Voltage resolution: 0.2 V maximum
3. Current Resolution: 0.02 A maximum
Set up the 'Power and Measurement Circuit' portion of the Deploy Test
10.1.2
Circuit per Figure 10-1.
Caution: If oscilloscope channels share common ground be cognizant of their
effect on the circuit.
May skip this step if no components/wiring were added since Set-for-Flight.
10.1.3
Verify the resistance between the PS and Lightband connector is less than
1.0 Ω for each motor. This applies to the complete loop (power and return).
Two methods are listed below.
a) Bypass the PS and measure resistance with a DMM from pins 1 to 4
(the relay will need to be activated). Then repeat from pins 5 to 8.
b) Set the PS to 1 V and short pin 1 to pin 4. Apply power (by activating
relay) and view current draw. R= V/I. Then repeat, shorting pin 5 to pin
8.
Set up the 'Test Circuit' per Figure 10-1 and connect to the 'Power and
10.1.4
Measurement Circuit'.
