Remote Regeneration; Relay Output Option - Pentair 962 Series Operation Manual

Remote Regeneration

A set of terminals with a programmable delay (P21) are
provided as a standard feature of the 962 control,
Figure 6. This feature allows for a regeneration to be
initiated from a remote location. This feature can also be
used to accommodate a differential pressure switch
input or any dry contact closure from external
equipment. Programmable value "P21" is used to
monitor this input for the amount of time that is
programmed (in seconds).
P21 is the length of time (in seconds) that the remote
input signal will be ignored before starting a
regeneration. THE CONNECTION MUST BE A NO
VOLTAGE DRY CONTACT.

Relay Output Option

A single pole double throw (SPDT) relay may be added
for outputs during Regeneration and Service mode. The
relay output option is available on single unit and Twin
Alternating models only. This feature may not be used
however, with the parallel multi-tank systems using the
lockout feature. The contacts of this relay are supplied
as "Dry Contacts" (un-powered). See Figures 7 and 8
for wiring information.
NOTE: The lockout feature is void when using the relay
output option.
