Conductivity Probe, Flow Switch and Water Meter Connections
3.5.1 Conductivity Probe
The conductivity probe contains eight wires. Lace conductivity probe wires through the
probe’s locking nut before wiring into panel. Bring wire into panel through supplied
waterproof strain-relief cord grip located on the bottom of Integrated Panel.
Connect wires to connector on Interface Board located on the left-hand side of panel door. Be
sure to connect the named, color-coded wires to the proper connector. See door label or

3.5.2 Flow Switch (System Dependent)
In the preferred configuration, a secondary contact (dry) from the tower recirculating water
pump-starter is wired into the X1 connection on the main Pulse~Pure circuit board. (See the
Pulse~Pure IOM for details of this connection). For an installation with multiple pumps where it
is impractical to connect the Pulse~Pure Integrated Controller Panel in this manner, the alternate
procedure should be used.
3.5.2.1 Alternate Procedure
A flow switch is used to control the conductivity-actuated blowdown-relay and
timer-relay while the Pulse~Pure Chamber operates continuously. Flow
switches require regular maintenance and may fail in the open (No Flow)
position. For the alternate procedure, jumper the X1 terminal on the Pulse~Pure
circuit board and move jumper JP-1 on the Interface Board from “PP +
COND” and center pins to center and “COND ONLY” pins. Connect a dry-
contact flow switch to the “FLOW SW” terminals on the Interface Board. See
Figure 4
.
3.5.3 Water Meters (Optional)
Water meter totalizers are digital counters designed to operate with a contacting head water
meter. Two water meters can be connected to the
