Note 1) Unassigned terminals may be connected to the internal circuit.
Do not use them as repeating terminals.
Note 2) Provide relay output of LD failure, LD temperature error, or connection error as analyzer faulty.
Note 3) Do not provide relay output of high gas temperature, air purge (low pressure), air purge (high
pressure), box temperature warning, PD over range or AI under.
Consult our sales representative to collectively provide relay output of alarm depending on the in-
stallation environment.
