SYCON
3000 H
Recorder interface
The analyser is equipped with 2 analogue outputs. The various instrument
states can be extracted as analogue values between 0-20 mA at the output RC
1 and the measured water hardness at the output RC 2.
In the programme steps 8.1 and 8.2 the desired measurement values are allo-
cated to the current values.
Further information on the recorder link can be found on page 9 in the section
"Recorder connection"
Connection and programming examples
Horn at the output OUT 1:
Function:

Function:
Function:
If the determined limit value is exceeded, the horn sounds for 60 seconds after every analysis.
Programming:
Programming:

Programming:
1.5 = MAX
=
Activation of the horn if the water hardness is exceeded (applies to all outputs)
5.1 = IMP
=
Generation of a pulse signal
5.4 = IMP | =
Activation of the horn function by operation of the relay
6.1 = 60s
=
Horn activation of 60 seconds duration
6.2 = 1 *
=
Activation of the horn when the limit value is exceeded for the first time
In addition, the indicator type, the water hardness unit, a correction factor and the water hardness
limit must be specified in programme steps 1.1 - 1.4.
