Bell & Gossett 176R0649C Technologic 502 Series Pump Controller - Manual (Page 73)

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 connections required.
Inspect and/or install any customer remote terminations
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.
Bladder storage tank
Precharge the bladder storage tank before connecting to the
system. The air precharge 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 charging valve
and pressurize to field conditions (equal to the NFSD restart
pressure or 5 to 10 psi below operating 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 tubing 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 tubing with insulation to prevent
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 on the drives to stop
the unit.
Enter/Confirm nameplate information
Go to the Quick Menu and enter motor nameplate
information.
Prove pump rotation for each pump
Press the Hand Start 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.
Reverse two leads on the pump motors that are incorrect.
If your system has PRVs, set the system operating
pressure. Skip next section if system has check valves
only.
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.
Run one pump manually by pressing Hand Start.
Adjust the PRV to the desired discharge pressure plus 2 to
5 psi for the building being served. (The PRVs should be set
slightly higher than the desired system setpoint.)
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 Quick Menu button.
Navigate and setup the system parameters.
Testing the package
Exit the Setup Menu.
Stop the package.
Press the Auto Start key to put the system into
Auto operation.
Observe the pressures and temperatures for normal
operation.
Press the Right Arrow key to initiate alternation 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!
