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
PO4 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 function
can be freely programmed for both contacts.
