Serial interface RS232
Testomat 2000
®
Polymer can also be connected to a log printer via
the serial interface RS232 to enable the printout of measuring results
and error messages. Analyses can then be continuously logged. This
option is only possible in connection with the RS-232 interface card
for log printer, RS910 (Art. no. 270310).
In >BASIC PROGRAM, select

Select the desired interface
Press "ENTER" to confirm the selection
SD Card Data logger
Analyses can then be continuously logged by using an SD Card data
logger (art. no. 100490) with the Testomat 2000
®
Polymer.
To operate the data logger correctly, proceed as described below:
In >BASIC MENU select
=> PROGRAM VALUES=> INTERFACES
Select "Type Data logger“
Press "ENTER" to confirm the selection
Description of the relay outputs
All relay outputs are neutral contacts. This ensures that all connection
options are available. The switching of mains voltage and external
voltage, and the direct switching of inputs, e.g. a process controller,
can be realised.
Flushing (external flush valve)
Immediately before each analysis the external flush valve is opened
for the programmed period allowing the line up to Testomat 2000
®
Polymer to fill with measuring water. Please ensure that the
programmed flush time is sufficient.
Please refer to "Entering further basic program data" "External
flush" for programming details
LV1 and LV2 limit value outputs
Two volt-free relay contacts are available to signal that a limit value
has been exceeded. The limit values, the hysteresis and the switch
function can be freely programmed for both contacts.
