8.12.2 Monitoring the current or voltage value received on the
analogue inputs
This function is used to define the behaviour of the limits entered by the user are reached.
Refer to section 8.9 to access the "Diagnostics" menu.

A malfunction in your process may be revealed by too low or too high value received on the analogue input.
To be warned when the value received on the analogue input is out of range:
→ choose which thresholds have to be monitored, in the "Thresholds" function, and then
→
set one or two threshold values outside of which the 8619 generates a "warning" event and displays the icons
and ;
→
set one or two threshold values outside of which the 8619 generates an "error" event and displays the icons
and
X
.
When a "warning" or "error" event is generated by the 8619:
→
go into the "Information" menu to read the cause of generation of this event;
→
correct the problem according to the instructions given in section 9.3.
• The "warning" event may also be associated with one and/or other digital outputs. See section 8.10.23.
• A current of 22 mA may be emitted on one and/or other of the current outputs when an "error" event related
to either the monitoring of the fluid pH, redox, conductivity or temperature values or the monitoring of an
analogue input is generated. See section 8.10.22.
• See also "If you encounter problems" in section 9.3.
WARN. LOW : Enter the analogue input value below which a "warning" event is generated.
WARN. HIGH : Enter the analogue input value above which a "warning" event is generated.
ERR. LOW : Enter the analogue input value below which an "error" event is generated.
ERR. HIGH : Enter the analogue input value above which an "error" event is generated.
