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 supply
such as a battery, PLC, DCS, etc.
The digital display responds instantaneously. When power is applied, the transmitter performs several self-
diagnostic system status checks termed as “START-UP TEST” as illustrated below:
START-UP TEST
