Setting Up Analog Output
The Sievers 500 RL On-Line TOC Analyzer has three 4-20 mA outputs. Select the output range for the 4-20 mA
analog outputs by following the steps below. Instructions for wiring the 4-20mA output can be found in the
“Installation” chapter on page 51. On configurations without conductivity measurement, some options are not
available.
1. Select the I/O tab.
2. Press the 4-20mA Outputs button.
3. Press the Error/Standby Configuration button. The settings here are applied to all the analog outputs
when each condition exists.
•Press the Error button and then press a button on the right to indicate the value for an error
condition, either 1 mA, 2.5 mA, 4 mA, 20 mA, 22mA, or LAST. (LAST = Hold the last measurement
until the next measurement.) The initial default value is 2.5 mA.
•Press the Standby button and then press a button on the right to indicate the value when the
Analyzer switches out of Analysis mode and into Standby mode, either 1 mA, 2.5 mA, 4 mA, 20 mA,
22 mA or LAST. The initial default value is 1 mA.
•Press the Warning button and then press a button on the right to indicate the value for a warning
condition, either 1 mA, 2.5 mA, 4 mA, 20 mA, 22 mA, or LAST. The initial default value is LAST.
4. Press the Back button.
5. Press one of the Analog Out buttons, either Analog Out 1, Analog Out 2, or Analog Out 3. Set the
values for the following:
•Press the Value button to set the output value that will be sent to the analog output. Press the TOC,
TC, IC, rCond, tCond, or Te
mp button and then press Enter to change the value, or press Cancel to
retain the current setting without making any changes.
•Press the Min button to set the minimum value (in ppb or µS), corresponding to the minimum analog
current. Enter a number and press the Enter button to save the value, or press Cancel to retain the
current setting without making any changes.
•Press the Max button to set the maximum value (in ppb or µS), corresponding to the maximum
analog current. Enter a number and press the Enter button to save the value, or press Cancel to
retain the current setting without making any changes.
6. To adjust the values output via the 4-20 mA outputs, see “Adjusting Analog Output Values” below.
Note:
The values for Error, Standby, and Warning should be different.
