In many applications, the measured parameters are used for control purposes. Neon
instruments can be equipped with a controller with two set points. With this you can
control actuators such as dosing pumps or valves to add chemicals until the desired
set point is reached. Alternatively, the measured signal can be used as input for an
external controller via the instruments´ interfaces.
Applications are for example neutralisation, detoxication, drinking water treatment,
industrial waste water, process water, disinfection, and process control.
As a safety precaution, measurement and calibration are checked for failure by the
instrument. Failures are indicated on the display via text messages that are stored in
an eventlog and via the alarm relay and, if activated, as 22mA current via the analog
output.
If the failure makes control unreliable, the controller is automatically switched off until
the failure has been taken care of.
Warning The instrument checks the input signals, calibration results, and
the water flow, if a flow sensor is connected. It cannot detect
erroneous settings or failures in the treatment system, nor can it
check for plausibility! The safety of the system of which the
instrument is part of lies within the reach of responsibility of
whoever built the system!
