Auxiliary Inputs
One auxiliary input is provided for optional signal devices such as remote push buttons, differential pressure switches,
hardness monitors, turbid meters, etc. for the purpose of receiving a regeneration signal. The Aux Input can also be con-
figured as an external alarm trigger.
To provide a regeneration signal, select an UNPOWERED contact within the remote device that will close when regener-
ation is desired. The duration of the switch closure can be as low as 0 seconds; 6 seconds is the recommended minimum
and default but can be as long as 999 seconds. The contact must automatically open following the start of a regeneration
sequence. Connect this contact to the Aux In terminal shown in Figure 40. The illustration below is an example of how to
use an external source (with duplex alternating current) to initiate regeneration.
To use as external alarm trigger, select an UNPOWERED contact within the remote device that will close when the alarm
condition exists. The duration of the switch closure can be as low as 0 seconds; 6 seconds is the recommended minimum
and default but can be as long as 999 seconds.
