Select the appropriate option above (Monitor or Control) for the
Analog Input that the halogen ana-
lyzer is connected to. If you are using the halogen analyzer to control oxidant feed, select the Bio-
cides tab in Control Settings and enter the set point and control range. The default range of the
analog output from the halogen analyzer is 0 ppm at 4mA and 5 ppm at 20mA. If this is suitable for
the application, enter these values into the corresponding fields in configurator
. If you alter the output
settings of the halogen analyzer make the adjustments in these fields so the input is scaled cor-
rectly.
!
IMPORTANT:
Disabling of halogen analyzer control of oxidant feed must
be done through the Analog Input Selection Screen and not through the
Biocide Control Settings Screen.

After the halogen analyzer is chosen, the FRH or TRH concentration will replace ORP on the sys-
tem operation screen on the OBC.
