Auxiliary Input (Optional)
One auxiliary input (P2 Aux In) input is provided for optional signal devic-
es such as remote push buttons, differential pressure switches, hardness
monitors, turbid meters, etc. for the purpose of receiving a regeneration
signal.
Select an UN-POWERED contact within the remote device that will close
when regeneration is desired. The duration of the switch closure can be
as low as 0 seconds; 6 seconds is the recommended minimum and de-
fault 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 P2 Aux In terminal shown in Figure 57.
