2.0 SETUP
2.1 Mounting
2.1.1
The CMS-2 does not require any special
mounting, and it will operate in any position. The
carrying case handle may be used to hang the monitor
in a convenient location that is close to the compressed
air source; refer to Section 2.3.
WARNING
DO NOT mount this instrument inside a blast
room. An operator inside a blast room wearing
protective clothing may not observe an alarm
condition. The alarm case is not designed to
withstand the continual impact of abrasive that
takes place inside a blast room. Refer to
instructions within the manual for installing
auxiliary horns, lights, and safety shutdown
devices.
2.2
Air Pressure Requirements
2.2.1 Air
Pressure:
If the compressed air source
pressure is between 55 psi and 100 psi, no pressure
adjustment is required. If line pressure is above 100 psi,
a regulator is required to reduce pressure to be within
the 55 psi to 100 psi operating range.
2.3
Connecting to Respirator Air Supply
NOTICE
Do not use pipe joint compound to seal pipe
fittings. The monitor will respond to the gases
given off by these compounds. Use Teflon tape
for pipe thread sealer.
Do not use any silicone-based lubricants up-
stream of this instrument. Silicone exposure
will prematurely damage the sensor.
2.3.1
To ensure accurate and rapid air monitoring, the
monitor must be placed as close to the compressed air
source as practical. Ten feet of 1/8" ID x 1/4" OD tubing
with two 1/4" NPT fittings are furnished, to be used
between the compressed air source and monitor inlet.
Larger diameter tubing or pipe, or longer tubing,
increases the air-supply volume, and the volume
determines the length of time it takes for the sample air
to reach the monitor.
2.3.2
Determine a suitable place to tap into the
compressed air supply. The tap location should be within
10 feet of the monitor, and the monitor must be placed in
a location that permits continual observance of the visual
and audible alarms.
