Note!
• Alarm values 1 and 2 do not need to be connected if the process control system sets its own alarm
values at the analog output.
• When using a sample conditioning system: connect terminals 57 and 53 on CA 71 to the
corresponding terminals of the sample conditioning system. For the allocation of these terminals,
please see the Operating Instructions of the sample conditioning system.
• If there is a 24 V voltage at terminal 57, the analyzer will not begin measurement (sample not
ready). To start measurement, the voltage must stay at 0 V for at least 5 seconds.
