3.3.11 Exercise ceiling pressure switch. With exercise ceiling
Pressure Switch 1154794 installed, and at pressures less than 20 psig, the
spot of channel 7 of the oscillograph shall be deflected 0.22 .12 in,
toward channel "1. At pressure greater than 20 psig, the spot of channel 7
shall be in the "not energized" position, when tested as specified in 4.6.10.
3.3.12 Depth cutout pressure switch. With depth cutout Pressure
Switch 815506 installed, the depth cutout pressure switch shall open at an
indicated pressure of 200 20 psig, when tested as specified in 4.6.11.
3.3.13 Enable and gate recording. Channel 4 of the oscillograph shall
deflect 0.60 0.19 in. toward channel 1, when tested as specified in
4.6.12.
3.3.14 Motor volts and rpm. Channel 7 of the oscillograph shall
deflect 0.50 0.25 in. toward channel 1, when tested as specified in
4.6.13.
3.3.15 Acoustic panel input. Channel 9 of the. oscillograph shall
deflect 0.50 0.25 in. toward channel 1, when tested as specified in 4.6.14.
3.3.16 Doppler channel. Channel 13 of the oscillograph shall deflect
1.0 0.5 in. toward channel 1, when tested as specified-in" 4.6.15.
3.3.17 Course. Channel 8 of the oscillograph shall show a 400 Hz
envelope 0.50 0.25 in. wide, when tested as specified in 4.6.16.
3.3.18 Steering relay. Channel 3 of the oscillograph shall show a
400 Hz envelope 0.15 0.06 in. wide and shall deflect 0.25 0.12 toward
than'nel 14, when tested as specified in 4.6.17.
3.3.19 Input level. The input level during a 30-second period shall
be no more than 4 millimetres (mm) wide and spikes shall not rise over 6 mm
from the bottom of the trace, when tested as specified in 4.6.18.
3.3.20 Wire command. Channel 1 of the oscillograph shall deflect
0.50 0.25 in. toward channel 14, when tested as specified in 4.6.19.
3.3.21 Noisemaker. When energized with 24.0 2.4 volts dc (Vdc) at
a steady current flow of 0.3 to .0.6 ampere, the noisemaker shall produce
maximum noise output when tested as specified in 4.6.20.
NOTE:
Noisemaker may be adjusted in
accordance. with Dwg 3029766.
