The analyzer provides an External Terminal Block on the outside of the Electronics Enclosure. It
allows the operator to connect to an external device such as a sequencer or sampler, monitor the
4-20mA ouputs and monitor alarm relays. The external terminal block can be configured from
the SERVICE Screen.
Table 3.1 below shows the terminal contact labels starting with pin 1 on the left.
