11.5.13 Current outputs
In the "current output" menu, the operator can assign
the selected values to the current outputs and then
assign the current outputs to the selected measuring
ranges.
In the "current output" menu, the selected
parameters are listed in the following order:
• Output 1: parameter group 1: chlorine, chlorine
dioxide, ozone, hydrogen and peroxide
• Output 2: parameter group 2: pH
• Output 3: temperature or continuous controller
for parameters from group 2
• Output 4: continuous controller for parameters
from group 1.
Assignment of the current outputs to the
measuring range (example: chlorine measurement)
There are two standard ranges, "0-20 mA" and "4-20
mA" which can be assigned to the current outputs.
They are assigned to the measuring range linearly.
The start-of-scale and full-scale values can be freely
defined within 0 to 20 mA in an optional setting for
the current outputs 1 and 2 as well as for current
output 3 with temperature measurements.
• In the corresponding submenu (for example
chlorine), select the line "others" using the [Up]
and [Down] buttons. Press [OK] to confirm.
• In the subsequent display "0.00 mg/l", enter the
start-of-scale value of the range using the [Up]
button. Press [OK] to confirm.
– In the same line, "= 0 mA" is displayed.
• Enter the associated start-of-scale current value
using the [Up] button. Press [OK] to confirm.
– An additional line is displayed with the scan for
the full-scale value of the range "20.00 mg/l".
• Enter the full-scale value of the range using the
[Down] button. Press [OK] to confirm.
– In the same line, "= 20 mA" is displayed.
• Enter the associated full-scale current value
using the [Down] button. Press [OK] to confirm
and return to the "current output" menu.
11.5.14 Program version
In case problems make it necessary to contact our
service department, the "program version" menu
enables the operator to easily identify the software
components of the actual device.
