CAL extern:
The Machine starts an external calibration independent from the mode the
machine is running in.
Signals at these inputs are only accepted if the location of control is set to
„PLC“ or „Local and PLC“. Refer to Chapter
6.6.4.1
2.2.2.4 Recorder
The recorder output Fig. 2 /7 may be used to chart the leak rate, the inlet
pressure and the forevacuum pressure. Both recorder activities can be
adjusted individually for showing leak rates and pressures.
The measured values are provided by way of an analogue signal in the
range of 0 V … 10 V. The resolution is limited to 10 mV. The instrument
which is connected to the recorder output (e. g. X(t) chart recorder) should
have an input resistance of no less than 2.5 k
Ω . The measured values are
available through pins 1 and 4. The reference potential (GND) is available
at pins 2 and 3. The contacts are numbered from bottom to top.
The chart recorder outputs are electrically isolated from other plugs. If, in
spite of this, hum interference is apparent it is recommended to operate
the PhoeniX and the chart recorder from the same mains phase. If this is
not possible, you must make sure that the frame ground of both instru-
ments is kept at the same potential.
