PREFACE
The following manual describes the new microprocessor based Technologic 350 Controller. This unit is in
the tradition of the other members of the Technologic
Control Panels as it incorporates many original, novel,
and proprietary features that may only be found on
B&G controllers. Some of these features require special
emphasis here.
The controller is best described as a specific purpose
programmable pump controller. This means that the
hardware and software have been created for the control and diagnostics of pumps with consideration for
their inherent characteristics. This results in an optimum pump controller without the cost of general purpose control hardware. Software is dedicated and
established for the unit only after extensive testing.
Changes to this software are not taken lightly and must
pass rigid version control.
The controller has the unique patented analog input
protection of other members of the control family.
Upon inadvertent higher than normal input voltage the
analog input resistor is sacrificed. An on-board spare is
used to replace the plug-in resistor. Extreme hi-voltage
is protected against by additional components.
Unique to this new controller are virtual selector
switches. Microprocessor control coupled with discrete
logic allows the pump keys to act as 3 position selector
switches. The 3 positions are hand-off-auto. Virtual
selector switches surpass standard selector switches
in that they can be changed from auto to hand automatically upon a fault in order to maintain a process. It
is novel that just as a standard selector switch can
change position (by human hand) with power off, so can
the virtual selector switch similarly change position.
Combined with the virtual selector switches is redundant control with discrete logic which is activated upon
a microprocessor fault. This is explained in detail in
Section 5.4.
In addition to this unique hardware the controller has
provision for four 4-20mA analog signals and two RTD
temperature inputs. Bell & Gossett is able to offer pressure (1PT, 2PT) and temperature inputs (T-1, T-2) as
options. The third 4-20mA is used for an optional flow
transmitter. The fourth 4-20mA is for optional temperature transmitter.
Bell & Gossett is thereby able to offer staging of pumps
by any one of 6 methods, i.e.; watts, amps, PSI and
GPM (flow), temp and Delta T. The main changes occur
in the menu entries.
Staging by watts is standard. A power transducer of
Bell & Gossett design is included. This transducer is
factory calibrated, single conductor sensing, wide current and voltage range, and automatic adaptability to
Wye or Delta systems either grounded or ungrounded.
At the customer’s discretion it may be used for amp
staging with the watt feature used to display total system power.
Note: The information contained in this manual is intended to assist operating personnel by providing
information on the characteristics of the purchased equipment.
It does not relieve the user of the responsibility to adhere to local codes and ordinances and the
use of accepted practices in the installation, operation and maintenance of this equipment.

Keep hands away from the output shaft until the
motor has completely stopped and power is disconnected from the pump controller.
WARNING: Motor can start automatically. Keep
hands away from output shaft until motor is completely stopped and input power is removed from the
motor control panel. Lockout main power switch while

electronic controls, there will be exposed components
at or above line potential. Extreme care should be
taken to protect against shock. Stand on an insulating
pad and make it a habit to use only one hand when
checking components. Always use accurate test
meters when checking electrical components. Always
work with another person in case of an emergency.
Disconnect power when performing maintenance. Be
sure equipment is properly grounded. Wear safety
glasses whenever working on electronic control or
rotating equipment.
DANGER: Troubleshooting live control panels exposes
personnel to hazardous voltages. Electrical trouble-
shooting must only be done by a qualified electrician.
Failure to follow these instructions could result in serious personal injury, death, and/or property damage.

STORAGE
For long periods of storage, the unit should be covered
to prevent corrosion and contamination from dirt. It
should be STORED in a clean, dry location between
-20 and +75°C. The relative humidity should not exceed 85%. The unit should be checked periodically to
ensure that no condensation has formed. After storage, again check that it is dry before applying power.
HANDLING
Care should be taken to prevent damage due to dropping or jolting when moving the Technologic Pump
Controller. Transportation damage should be brought
to the carrier’s attention immediately upon receipt.
TEMPERATURE AND VENTILATION
All electrical equipment is susceptible to failure if
operated in ambient temperatures outside of its rating. The OPERATING temperature range for this unit is
0 to 40°C. The relative humidity should not exceed 95%
non-condensing. The unit should not be operated
outside these extremes.
WARNING: Prevent electrical shocks. Disconnect the
power supply before beginning installation. Failure to
follow these instructions could result in serious personal injury, death, and/or property damage.
GROUND CONNECTIONS
A grounding terminal is provided for a dedicated
ground wire connection. All provisions of the National
Electrical Code and local codes must be followed.
WARNING: Conduit grounds are not adequate. A
separate ground wire must be attached to the ground
lug provided in the enclosure to avoid potential safety
hazards. Failure to follow these instructions could re-
sult in serious personal injury, death, and/or property
damage.
Power wire types and sizes must be selected based
upon conformance with the National Electrical Code
and all local codes and restrictions. In addition, only
copper (Cu) wire rated for 75°C (minimum) may be
used for the power connections. Refer to the input
current as listed on the nameplate on the enclosure
door when sizing wire.

DANGER: Heavy load, may drop if not lifted properly.
Do not lift the entire unit by the motor eyebolts. Lift
the unit with slings placed under the unit base rails.
Failure to follow these instructions could result in serious personal injury, death, and/or property damage.
INSTALLATION
This unit is built to give you years of service; install it
properly and provide a suitable foundation. (Check
the shipping ticket for unit weight.) Mount the unit to
provide a rigid connection that will not move or shift
under any circumstance.
LEVELING
Mount the unit on a level surface and check that it is
plumb on all sides.
DANGER: Electrical shock hazard. Inspect all electri-
cal connections prior to powering the unit. Wiring
connections must be made by a qualified electrician in
accordance with all applicable codes, ordinances, and
good practices. Failure to follow these instructions
could result in serious personal injury, death, and/or
property damage.
The Technologic 350 control panel can be set up to
operate across a broad range of voltages. It was factory set to operate on the voltage shown on the nameplate. Verify proper transformer primary wiring per the
job-specific wiring diagram. Check power leads in
accordance with wiring diagram enclosed in control
cabinet. The voltage tolerance is +10%/-10%.
ANALOG SIGNAL WIRING
If installing the panel on an existing system, shielded
cable (#22 AWG, Belden type 8762, Alpha #2411 or
equal) should be installed for the DC control wiring.
The shield must be terminated in the Technologic 350
control panel. Do not connect the shield at the other
end of the cable! Insulate the shield so that no electrical connection is made at the other end of the cable.
A twisted pair of #22 AWG conductors (Belden 8442
or equal) can be used in place of shielded cable. The
cable length must be limited to 3000 feet for #22
AWG wire.
