Establishing Power to Electronics
Once the two power input wires of the shielded cable are properly connected to the terminals inside the Ex
enclosure as described above, connect the other end of the two wires to a suitable 12-24 VDC power source
such as a battery, PLC, DCS, etc.
The digital display responds instantaneously. The transmitter performs several self-diagnostic system status
checks termed as
“START-UP TEST” as illustrated below:
After self diagnostic tests, the analyzer turns itself into the sampling mode. And displays H2S contents the
sensor is exposed to, the analysis range, the ambient temperature and pressure, High and Low alarm set
