Constant Speed Pump Controller Installation, Operation and Maintenance Manual
41
Read these instructions completely before beginning.
Confirm job site voltage. Do not apply power or
close the disconnect until the following items are
completed.
Check all power wiring connections and secure as
required.
Confirm with the owner/installing contractor if there
will be any building automation or remote connec-
tions required.
Inspect and/or install any customer remote termina-
tions required.
Make note of the design data supplied on the B&G
data label (inside of the control panel door)
Use a volt meter to measure phase to phase voltage
on the entering power terminals at the disconnect.
Compare available voltage to the nameplate data.
Field install the supply water temperature sensor
(suction RTD)
Locate the sensor and connection wiring coiled in the
panel (may have been coiled outside of the panel by
the factory). Uncoil and feed the sensor through the
back of the panel through a hole.
Locate the sensor on the suction water supply pipe as
far from the header as practical.
Tape to the piping in such a manner as to protect the
sensor and wiring from damage.
Insulate the sensor with foam or fiberglass to prevent
sensing ambient temperature.
Bladder storage tank
Precharge the bladder storage tank before connecting
to the system. The air precharged should be 5 to 10
psi less than the system operating pressure.
If the storage tank has already been installed and not
precharged, disconnect system piping from the tank
and equalize to atmospheric pressure, if an isolation
valve and drain are provided, use them.
Apply air pressure to bladder through the air charg-
ing valve and pressurize to field conditions (equal to
the NFSD restart pressure or 5 to 10 psi below oper-
ating pressure)
Reconnect to the system piping
Check for available suction water
Open all supply and discharge valves.
Close bypass valve if installed in the piping by others.
Inspect the capillary tybing from the pump discharge
to the suction header.
Open petcocks feeding the tubing.
Ensure that the plastic tubing is not touching any
metal surface. Protect tuving with insulation to pre-
vent abrasion where it may be touching metal.
Use the pump vent plugs and or the vent cocks on the
main prv to prove available water for suction. Open a
faucet to create a demand for water on the system
pressure piping.
Start the package
Close the disconnect to apply power to the package.
If the unit starts, press the stop button to stop the
unit.
Prove pump rotation
Confirm that the Auto/Manual LED is off to indicate
manual operation mode. If it is not, press the Auto/
Manual key.
Enable one pump (LED blinking) and disable all oth-
ers (LED off) by pressing the corresponding Pump
Enable keys.
Press the Start/Stop key to start the pump and then
quickly press the Pump Enable key to stop it.
Observe the spinning shaft for rotation.
Repeat for each pump
If all pumps run backwards, reverse two leads of the
incoming power.
If only one or less than all pumps run backwards,
reverse two leads on the pump motors that are incor-
rect.
Set the system operating pressure
Open a faucet or some other demand for water from
the discharge of the package. This can be anywhere
in the building being served by the package.
In Manual, run one pump.
Adjust the PRV to the desired discharge pressure for
the building being served.
Repeat for each pump in the package, running only
one pump at a time.
All PRVs should be adjusted to the same pressure as
seen on the display.
Set system specific parameters
Press the Setup (3) key to enter the setup menu.
Press 6 and Enter to get to EZ-Start.
Use the arrows to navigate to the next screen, or
press No (4) and Enter to edit the values. When
EZ-Start is complete (the right arrow is not blinking),
Press Yes (1) and Enter to exit EZ-Start.
Testing the package
Exit the Setup Menu.
Stop the package
Press the Auto/Manual key to put the system into
Auto operation, and the press Start.
Observe the pressures and temperatures for normal
operation.
Press the alternation key, and the select Yes(1) and
press Enter at the prompt, and observe each pump’s
operation.
Close the running water faucet. It should be assumed
that no demand for water is required. (No Flow)
Wait for the no flow shut down sequence to engage.
All minimum run timers must elapse for this to occur.
Demand water from the system again and observe the
restart of the package.
No problems? You are done!
