OF OTHER ELECTRONIC COMPONENTS.
7Plumbing Installation
PLUMBING MATERIALS
Inlet plumbing can be ¾ inch (1.9 cm) PVC, CPVC, or iron pipe.
Provide at least 1 gpm (3.79 Lpm) to the sensor. A 4-psi (0.3 bar) differential pressure from take-off
to injection is sufficient. If flow is marginal, consult your Pulsafeeder Factory Representative. The
maximum recommended flow is 5 gpm (18.93Lpm).
Outlet plumbing can be ¾ inch (1.9 cm) PVC, CPVC, or iron pipe. PVC, CPVC Schedule 80 is
recommended for strength and sunlight protection.
If iron pipe is used, install a PVC union to relieve the stress on the plumbing.
The sample line inlet should be plumbed downstream of the recirculating pump and upstream of the
heat exchanger. This line brings the sample water into the sensor plumbing for conductivity
measurement. If the Pulsafeeder flow switch plumbing assembly is used, this flow of water also
pushes the flow switch float up to activate the relay outputs of the controller.

8Electrical Installation
8.1 Incoming Power 115/230 VAC
The controller can be powered from either 115 VAC or 230 VAC at 50/60 Hz. The controller comes with
a power cord and receptacles. The power cord and receptacles are rated for 115VAC. If the controller
will be powered by 230 VAC, the power cord and receptacles will need to be removed and the incoming
power and the relay outputs will need to be hard-wired.
The incoming power is connected to terminal block TA at the bottom right corner of the power supply
board. There is a hot or line input (terminal 4), a neutral input (terminals 2 and 3) and an earth ground
input (terminal 1). The hot is wired to the fuse holder located on the bottom of the enclosure. The
neutrals are wired directly to terminals 2 and 3 of terminal block TA. Refer to the drawing in the back of
this manual for wiring instructions.
8.2 Relay Outputs
The relay outputs are of the same voltage as the power input. Ensure that the devices that are to be
connected to the relay outputs are of the same voltage rating or damage will occur.
The relay outputs are wired to the receptacles. The receptacle on the far left is relay #1 and the
receptacle on the far right is relay #4. On the power supply board, relay #4 is on the far left and relay #1
is on the far right. If 115 VAC is used simply plug your devices into the molded receptacles. If 230 VAC
is used, remove the receptacles and hard-wire your devices to the relay outputs.

12
Relay #1 and #2 have both a normally open and normally closed contact. This is designed for use with
motorized valves. The normally open (NO) contact is connected to the open connection of the valve and
the normally closed (NC) contact is connected to the close connection of the valve. The other two relays
only have a normally open contact. Each relay output requires a neutral connection and an earth ground
connection for proper operation.
Refer to the drawing in the back of this manual for wiring instructions.
WARNING! DO NOT PLUG IN CHEMICAL PUMPS THAT ARE LARGER THAN 1/6 HORSEPOWER.
THE CONTROL RELAYS ARE INTENDED FOR ELECTRONIC OR SMALL MOTOR-DRIVEN
CHEMICAL PUMPS. LARGER PUMPS REQUIRE THE -HR OPTION WITH 25-AMP-RATED
INTERPOSING RELAYS. CONTACT PULSAFEEDER FOR SPECIAL INSTRUCTIONS.
8.3 Flow Switch Wiring
The controller has a flow switch input. The purpose of the flow switch input is to disable the relay
outputs on a loss of flow in the system. The flow switch input requires a digital contact. Any digital
contact rated for 24 VDC and 500 mA may be used, such as a relay driven by the recirculation pump.
Pulsafeeder manufactures a flow switch plumbing assembly for use with the unit.
If a flow switch is not used then a jumper must be installed across the flow switch connections. Refer to
the drawings in the back of this manual for wiring instructions.
8.4 Water Meter
The controller will accept two water meter inputs. These inputs can be configured for make-up, make-up
Second Source, Bleed, or Chill Loop make-up. Refer to the water meter manufacturer‘s manual for
plumbing information.
The controller will work directly with the following types of meters: dry contacting head meters,
Seametrics open collector output meters, Signet 2535 and 2540 paddle wheel meters, and the Autotrol 1
inch and 2 inch meters. Contact Pulsafeeder for other types of water meters. The water meters are
wired to terminal block P1 which is the top terminal block on the I/O board.
Refer to the drawing in the back of this manual for wiring instructions.
8.5 4-20 mA Output Wiring
If the 4-20mA option is ordered, the controller will have two channels of 4-20 mA outputs. This output
can be isolated (externally powered) or non-isolated (internally powered). The 4-20 mA outputs are
wired directly to the 4-20mA option card.

13
Refer to the drawing in the back of this manual for wiring instructions.
8.6 Node Wiring
If optional nodes are ordered they must be wired to the controller before installation and programming
can take place. Nodes require +24 VDC for operation and twisted pair wire for data transmission. The
network interface option card can provide the +24 VDC for up to two nodes using non-twisted pair wire.
If using three or more nodes an external +24 VDC power supply run in parallel is recommended.
Recommended twisted pair for data specifications are:
Beldon 85102, single twisted pair, stranded 9/29, unshielded, plenum.
Beldon 8471, single twisted pair, stranded 9/29, unshielded, nonplenum.
JY (ST) Y 2 X 2 X .8, UL Level IV 22 AWG, twisted pair, typically solid and unshielded.
Four wire helical twist, solid, shielded.
If shielded cable is used, the shield should be connected to earth ground via a 470K ohm, .25 watt,
metal film resistor to prevent static charge buildup.
Nodes are wired directly to the NIN card inside the controller enclosure.
Please refer to the diagram in the back of this manual for wiring instructions.

11.2 Manual Operation of the Relays
All four of the relays can be operated manually. To manually operate the relays:
Go to the Process screen. Press ―ENT‖. You will be taken to a screen that looks like:
AUTO-MANUAL (5 MINS.)
(1) BLOW
(2) RLY2
(3) RLY3
(4) RLY4
Press 1-4; BACK=EXIT
PRESS 1-4; CL
EXIT
Press ―1-4 ― to manually change the state of that particular relay. If the relay is already on, pressing that
number will turn it off. A five-minute countdown timer will start. After five minutes has expired the relay
will return to automatic control. A relay that is in manual control will stay in manual control until the five
minutes expires even if this screen is exited. The five-minute timer helps to prevent damage to the
system if a relay is left in manual. WARNING: Manual control overrides everything including the
flow switch input. Use care when operating relays manually with no flow in the system.
12 Calibration of Conductivity and ORP
12.1 Calibration of Conductivity
The conductivity requires periodic calibration. Calibration is usually required after cleaning the sensor.
Calibration should always be performed with the sensor in the piping assembly with good flow past the
sensor. It is necessary to have an accurate reading of the blowdown water to properly calibrate the
controller. A hand-held conductivity meter that tests the sample works well for this purpose. If a meter
that measures ppm is used, refer to the conductivity vs. ppm chart in section 12.3 and convert the ppm
to an approximate conductivity value. Buffers can be used to check calibrations but should not be used
for calibration purposes (see below).
The controller uses a single point calibration. A two point calibration is not necessary if using a
Pulsafeeder conductivity sensor.
Ensure that the controller is operating with good flow past the sensor.
Take a sample of the water and measure with a hand-held conductivity tester.
From the PROCESS screen, press CAL to enter the calibration screen. Use the keypad to input
the conductivity reading from the hand-held. Press ―ENT‖.
Take another hand-held sample to verify calibration.

12.2 Calibration check of conductivity in buffer solutions
To check the calibration of the sensor in buffer solutions, the sensor is placed in a container of the buffer
solution. Ensure that the sensor tips are centered in the container away from the edges and the bottom
of the container. The conductivity values displayed can vary depending on the position of the
conductivity sensor in the container of buffer solution.
Perform the calibration check as follows:
Shut the isolation valves to the controller plumbing assembly.
Place the Conductivity sensor in the buffer solutions.
Verify calibrations in at least two buffer solutions.
Re-install the sensor into the plumbing. Ensure locking ring is locked. Restore flow to
plumbing assembly
12.3 Conductivity vs. ppm
The unit measures the conductivity of the water. The ppm of the water may be measured instead of
conductivity. If ppm is measured, use the following chart for an approximation of the conductivity level
and calibrate to the conductivity level that is closest to the ppm level that is measured. Remember this is
just an approximation because the ions that make up the conductivity may be different than the particles
that make up the ppm reading.
