Check that the power cords of both the compressor and the two Tri-Gas Generators are connected
to their proper power supply outlets. Check that the Tri-gas generators are not powered on (all
LEDs are not lit). Check that the depressurize valves are closed (see fig. 21). Valve lever is posi
-
tioned 90° to the valve body when closed.
Rotate the Power Switch to On (
I
) (see figure 15) on the front panel of the compressor cabinet.
The compressor will start and the green LED will illuminate. The pressure gauge indicates system
pressure slowly increasing to a maximum set pressure of 140 psig (9.6 barg). Full pressurization will
occur within 10 minutes. The compressor is ON for about 2 minutes and OFF for about 5 minutes
when the generator is operating at the maximum rated capacity.
Press the power switch on the top rear side of the two Tri-Gas generators to turn them on (I) (see
figure 16). There is a 45 minute warm-up period. The LEDs on the front panel indicate the following:
The yellow “Low Pressure” LED temporarily illuminates until the system pressure reaches
105 psig (7.2 barg) for model LCMS-SF5000 (for models LCMS-SF5001T and LCMS-SF5001NT, 85
psig or 5.8 barg). The yellow “Low Temperature” LED illuminates up to 10 minutes, then goes out.
The green “System Ready” LED blinks for 45 minutes until the zero-air generator reaches the speci
-
fied temperature for hydrocarbon removal level. The green “System Ready” LED then will remain
illuminated. The six pressure gauges should indicate 0 psig. The six flow meters should indicate
zero flow.

Tri-Gas Generator
The LCMS-SF5000 Generator requires 45 minutes of warm-up time to achieve rated gas
purities.
During normal operation, the compressor cabinet has one display LED illuminated: green “ON”
power switch (see figure 17). The compressor pressure gauge indicates a pressure between 110
to 140 psig (7.5 to 9.6 barg). Each Tri-Gas Generator cabinet has one display LED illuminated
“System Ready” (green) (figure 18). After each generator has completed the 45 minute warm-up
period, the two generators are ready for setting outlet pressures.
To set the six pressure regulators, pull the regulator knob to unlock. Turn the knob clockwise to
increase pressure, and counter clockwise to decrease pressure. Push knob in to lock the set-
ting. Set the six regulators to the specified values required by the instrument. The flow rate is
displayed by a flow meter for each of the six gases. The flow meter has a dimensionless gauge.
Refer to either the flow chart in the Specifications section of this manual or the outlet flow label on
the top of the Tri-Gas Generator cabinet for the correct flow reading. The flow rates are normally
set at the instrument.
The compressor operates on a 30% duty cycle (pump on about 2 minutes, off 5 minutes) for
maximum service life at the rated maximum flow/pressure specifications. A pressure switch shuts
off the compressor at about 140 psig (9.6 barg) and starts the compressor at about 110 psig
(7.5 barg). There is a “burping” sound lasting about 2 seconds each time the compressor shuts
off. The sound is the air pressure being released from the compressor pump.
