!
Note!
•
Alarm values 1 and 2 do not need to be connected if the PLC sets its own alarm values
at the analog output.
•
When using a sample conditioning system:
Connect terminals 57 and 53 on the CA 71 to the corresponding terminals on the
sample conditioning system. For the allocation of these terminals, please see the
sample conditioning system operating instructions.
•
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.
