ANALOG OUTPUTS

The PCA 310-330 analyzers has two current analog outputs.

Each one can be configured as 0-20 mA, 4-20 mA or dosing

type. Also they can be assigned to one of the measurement

parameters: Cl, pH, Orp, Temp.

SELECT THE ANALOG OUTPUT TYPE

To select the analog output type enter in “General Menu” -

“Analog Output1” or “Analog Output2”.

The analog output

could be assigned

to one of the four

measured parameters.

To define this assign-

ment, edit the “Out

Param.” field. “Chlorine”, “pH”, “ORP” and “Temper.”

options are available.

To select the analog output type edit the “Type” line. The

available options are: 0-20 mA , 4-20 mA current outputs.

DOSING THROUGH 4-20 mA OUTPUT

Select “General Menu” - “Analog Output1” or “Analog

Output2” - “Type” as Dosing to activate this feature. The

output become 4-20 mA current type, proportional with pH

or chlorine regulator output.

The 4 mA correspond with pump stop and 20 mA correspond

to pump operating at full speed.

This mode should be selected when a proportional pump is

attached to the analyzer.

Note: In this mode calibration is not allowed. If calibration menu is

entered, the following message appears: “Analog output value

cannot be changed when analog output type is dosing”.
