Interactions Affecting Permitted Relay Assignments - Honeywell 9782 Series Operator's Manual

Conductivity/Resistivity Analyzer/Controller

Interactions affecting permitted relay assignments

Table 1-3 is provided so that you can optimize your use of relays to implement your control
strategy. Each row in the table represents an available combination of relay assignments for a
single feature or multiple alarms.
ATTENTION
AutoClean and range status indication cannot be selected for use with two cells simultaneously.
Your choices are:
For Cell 1 only, use AutoClean (Relay 1) and/or range status indication (Relay 2).
For both Cell 1 and Cell 2, use AutoClean (Relays 1 and 3), with no range status indication,
nor any discrete control.
For both Cell 1 and Cell 2, use range status indication (Relays 2 and 4), with no AutoClean,
nor any discrete control.
When reading the tables keep in mind the following:
The entry "Diagnostic" in the tables indicates that the relay can be used to indicate the
unit's failure of a self-test (see 9.4).
The entry "or discrete control" means that the relay can be assigned to discrete control
or to one alarm. If the relay is selected for discrete control, then the alarm choice
sharing the cell in the table with "or discrete control" will not be available in that
row's combination of relay assignments.
If the Analyzer/Controller has only two relays, then only the choices for Relay 1 and
Relay 2 will be available.
