It is advisable to carry out an initial purge of the sample loop before installing the
transmitter in order to eliminate the possibility of damage on startup.
Before the transmitter is installed into the sample block open the inlet isolation valve slowly
until a small flow of process gas flows though the transmitter block and exhausts through
the transmitter block outlet transmitter opening.
Allow the purge to continue for about 20 minutes to remove residual moisture from the
sampling pipework. Close the inlet isolation valve and install the transmitter into the
sampling block. Connect the cable and secure it using the retaining ring.
Note: The plugs and sockets only locate in one position because the pins are of different
sizes in the tip, and the main connector is keyed.
Open the inlet slowly and allow a low pressure purge through the whole system. Set the
required pressure flow within the sample loop.
The instrument is ready for use as soon as the power cable is installed. When power is
applied the instrument will initialize its program.
Once completed and powered, the device is on line but gas sample lines could take
several hours to clean up and reach equilibrium.
