6.2.4 PGA 3 unit connection 6.2.3 Description of the PGA 3
The PGA 3 reads out the setup/actual values
received from the respectively selected pulse
meter. The measured values are displayed in
”Pulses/Min” or alternatively in ”Liters/Min”.
Moreover, the PGA 3 is also used to program
the threshold values and enter the groups for
the master and slave devices (IPM 12).
The measuring results are read out of the re-
spectively selected IPM 12 pulse meter via the
RS 232 serial interface. The data can be pas-
sed on to the downstream OPC server via a
LAN interface.
