30931, 30576, 30817 and 30599 the system is
powered from the 26 VAC buss # 1. For all S/Ns
except 30687, 30931, 30576, 30817 and 30599
the system is powered from the 28 VDC buss.
95.7.5 Fuel Quantity Indicator
The fuel quantity indicator (M25) provides
readings of fuel supply quantity in total pounds.
For S/Ns 30687, 30931 and 30576, a fuel
quantity selector switch allows for indication of
fuel quantity as determined by the position of the
switch (LEFT, TOTAL or RIGHT). For all S/Ns
except 30687, 30931 and 30576, a fuel quantity
test switch has replaced the fuel quantity select
switch and allows for a confidence check of the
indicator only. The indicator displays total fuel
quantity at all times. In either case the system is
powered from the 115VAC buss.
95.7.6 Gas Producer Tachometer
Indicator
The engine gas producer tachometer indicator
(M17) registers percent rpm of the engine gas
producer speed. The gas producer tachometer
generator sends voltage signals to the indicator
proportional to engine gas producer speed. For
S/Ns 30687, 30931, 30576, 30817 and 30599 the
gas producer tachometer indicator system is self-
generating. All S/Ns except 30687, 30931,
30576, 30817 and 30599 use 28 VDC power to
display a digital readout and store any
exceedences.
95.7.7 Hydraulic Temperature and
Pressure Indicators
Hydraulic system 1 and 2 temperature and
pressure indicators (M36 and M37) are dual type
indicators registering hydraulic oil temperature
(degrees Celsius) and hydraulic pressure (psig).
For S/Ns 30687, 30931, 30576, 30817 and
30599 the pressure portion is powered by the 26
VAC busses and registers indications received
from 2 hydraulic pressure transmitters. For all
S/Ns except 30687, 30931, 30576, 30817 and
30599 both the temperature portion and the
pressure portion are 28 VDC.
95.7.8 Transmission Oil Temperature and
Pressure Indicator
Transmission oil temperature and pressure
indicator (M16) is a dual type indicator registering
temperature (degrees Celsius) and pressure
(psig) of oil in the transmission. The temperature
portion receives temperature indications from an
electrical resistance type bulb and the pressure
portion receives pressure indications from an oil
pressure transmitter. For S/Ns 30687, 30931,
30576, 30817 and 30599 the temperature portion
is 28 VDC powered and the pressure portion is
26 VAC powered. For all S/Ns except 30687,
30931, 30576, 30817 and 30599 both the
temperature portion and the pressure portion are
28 VDC.
95.7.9 Dual Tachometer Indicator
The dual tachometer indicators (pilot M12 and
copilot M11) contains two pointers and
simultaneously register engine power turbine and
main rotor rpm in percentage. Power is provided
by two tachometer generators mounted on the
engine and transmission respectively. Both
indicators receive indications from each of the
tachometer generators. For S/Ns 30687, 30931,
30576, 30817 and 30599 the system is self
generating. All S/Ns except 30687, 30931,
30576, 30817 and 30599 use DC power for
internal regulation.
95.7.10 Measured Gas Temperature (MGT)
Indicator (-17B Engines)
Engine measured gas temperature indicator
(M23) registers power turbine inlet air
temperature received from bayonet type
thermocouples mounted between the gas
producer turbine and the power turbine. The
temperature indications are in degrees Celsius.
95.7.11 Exhaust Gas Temperature (EGT)
Indicator (-17A Engines)
