GENERAL:
TR3210-NO
2
is designed for measure exhaust gas in parking
garages. The electrochemical sensor is much less sensitive to
other gases and less likely to be poisoned.
The loop powered sensor delivers a linear 4-20 mA output that
is easily integrated into any building control, ventilation or alarm
application.
MEASURING RANGES AND ALARM LEVELS:
Relevant alarm levels depend on application.
STANDARDS AND REGULATIONS:
Check local standards and regulations as hygienic max values
etc.
INSTALLATION
Locate a flat surface to mount the enclosure approximately
20cm above the floor. The power entry is at the bottom of the
enclosure.
Remove the cover of the enclosure by removing the 2 screws.
Be careful here since the circuit board and the sensor are
connected to the cover. Set the cover/electronics safely aside
while connecting the conduit and pulling in the wiring.
Connect the electrical fittings to the enclosure and bring in the
electrical wirings.
NOTE! BE SURE THAT WIRING IS DONE ACCORDING TO
THE LOCAL ELECTRICAL CODE REQUIREMENTS.
Connect the wirings to the terminal block as shown on the
wiring drawing. NOTE POLARITY.
