3.3.1 How to Power Up and Power Down Composer Elite
Operating Composer Elite requires a 24 V power connection. Refer to section 1.5.4
on page 1-11 for complete power specifications.
To power up Composer Elite,
1 Connect the 24 V(dc) power supply
(see section 1.5.4, Power Supply, on page 1-11).
2 Set the ON/OFF (I|O) power switch on the rear panel of the Sensor Control Unit
in the ON (I) position (see Figure 3-8 on page 3-14).
To power down Composer Elite, set the rear panel of the Sensor Control Unit in the

CAUTION
When powering down Composer Elite, make sure the
precursor gases are completely purged from the
Acoustic Sensor. When power is removed from the
Sensor Control Unit, the Acoustic Sensor temperature
will cool to room temperature. If precursor gases are not
completely purged, condensation of precursor gas inside
the Acoustic Sensor may occur as the Acoustic Sensor
cools down.
