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.

(CPU Fails, Watchdog LED on)
The Technologic 350 has a redundant feature allowing
critical operation even though the microprocessor and
its support I.C.’s may have failed. Although this is a
rare occurrence, B&G has planned for this possibility.
When the Watchdog LED is “on” a separate section of
LOGIC is used to bypass the problem area. This
LOGIC has its own memory which is held with power
off by a small clock battery (B1). This memory must
be pre-set for operation as desired upon CPU failure.
To set this memory perform the following (assuming
unit is running in auto):
1. Press STOP Key – Red stop LED is on.
2. Press AUTO/HAND Key – Red HAND LED is on.
3. Press PUMP ENABLE keys in any order for pumps
to run upon a CPU failure. Associated green LED’s
will flash.
4. Press AUTO/HAND key – green AUTO LED is on.
5. ENABLE PUMPS as required and press
START/STOP key – green LED on.
The unit is now running in auto. If the CPU fails the
system reverts to the manual operation that was preset in steps above. Pumps do not stop except for
overload trip. Press the PUMP ENABLE key to stop a
specific pump or press START/STOP key to stop all
pumps.
Press PUMP ENABLE key to re-start a pump. Only the
hand and pump LED’s are active. All other LED’s and
the display are off.
SECTION 6 – MANTENANCE
6.0Preface: The following is a description of the hard-
ware, diagnostics, and corrective action to maintain a
process being controlled by the Technologic 350.
NOTE: The following should not be interpreted as the
maximum configuration of this controller, rather this
describes its application as a Technologic 350 only.
6.1TECHNICAL OVERVIEW
The Technologic 350 is a micro-processor based
dedicated pump controller unique to and exclusively
manufactured by Bell & Gossett. All aspects of
this unit are strictly proprietary to Bell & Gossett.
It consists of 3 electronic assemblies. The first assembly consists of 3 circuit boards, i.e., display, keyboard, and central processor unit (CPU) and is
referred to as the operator interface panel (OIP).
This operator interface is connected (with ribbon
cable) to a large board assembly known as the
input/output (I/O) board. This board contains a 24 volt
DC power supply to power the unit, all I/O, and a limited number of sensors. It also has the terminals to
connect to external devices. All hard wire interface to
the outside world resides on this board and is protected from the external environment.
The third electronic assembly is the power board
which connects to the OIP with a special cable. This
board senses amps, voltage, and calculates the total
power for staging and display on the OIP.
6.2DIGITAL INPUTS
The controller has provision for digital inputs with a
voltage operating range of 22 to 26.4 VDC. This signal
voltage must be obtained from the on-board 24 VDC
power supply. Eighteen terminals are provided with 6
of these terminals used to connect to the 24 VDC
power supply.
It is not recommended that other power sources
be used without factory approval.
The terminal will accommodate (2) No. 18 AWG wires.
6.3DIGITAL OUTPUTS
The controller has provision for relay outputs to control 120 V 50/60 HZ devices.
Sixteen terminals are provided. All terminals will
accept up to (2) No. 14 AWG wires.
The relays are not removable. If defective the I/O
board must be returned to the factory for repair.
All relays operate as single pole single throw.
Components are provided to reduce contact arc and
extend electrical life.
6.4ANALOG INPUTS
Analog inputs are provided on the I/O board for
process variables and for flow readout. All analog
inputs operate at 4-20mA. They may be powered
from 24 VDC on board or self powered, in any mix,
without isolators.
Each analog input has 4 terminals associated with it,
i.e., 2 for signal input, 1 for 24 VDC, and 1 for shield
chassis ground.
Each analog input terminal will accommodate (2) No.
18 AWG conductors.
6.5MEMORY
6.5.1The EPROM is the only removable chip. However, it
is not recommended that it be changed by other than
the factory.
The EPROM is programmed by Bell & Gossett and
its code is copyrighted. On power up the software
version is displayed as FW RELEASE VX.XX on the
top line and unit assembly serial No. on the bottom
line.
6.5.2The EEPROM holds all data entered by the operator.
It is not removable. Old data is erased with new. All
data may be erased by the factory at which time all
data reverts back to default values published elsewhere in this manual.
6.5.3The RAM chip is not replaceable and requires no
maintenance.
6.6CPU
The CPU does not require any maintenance, and cannot be replaced as a field repair.
6.7POWER SUPPLY
The power supply provides 24 VDC for all digital and
analog signals. It is specifically rated only for the controller and other loads should not be applied without
factory approval.
The power supply also supplies 5 VDC for all TTL
devices.
The power supply is protected with Fuse F1 located
near the 120 VAC line terminals.
6.8DIAGNOSTICS (SERVICE TEST)
The Technologic 350 has built in I/O diagnostic capabilities activated with a SERVICE TEST key while in
normal message scroll. It consists of 2 menus, i.e.,
read only and read/write. Read/write overrides the
program and requires a security code.
NOTE: Service test cannot be used if any of the following occur.
1. Power is off.
2. Display and or the start/stop LED is off (red or green).
3. Watch dog LED (CR6) on the I/O board is on.

6.9.4Corrective Action – compare the inputs to the
device/s connected to the digital inputs and trigger
same. If a “1” is not received check the associated
wiring or the particular device and correct or replace
the cause of the fault.
6.9.5Controller Operation – the keyboard (except the
CLEAR key) and all LED’s cannot change state. The
display is dedicated to the digital input display. The
program is otherwise active.
6.9.6Exit – press CLEAR twice and then press ENTER
twice.

type and measurement on bottom line. Press key 1, 2,
3 or 4 to read channels 1, 2, 3 or 4 in % with 4mA @
20% and 20mA at 100%. Six other items may be
accessed with the up arrow key. These items are:
RTD 1(°F), RTD 2(°F), DC supply (DCV), and power
board readings. “Power Board Readings” is now displayed on top line. These readings are: voltage in
volts, current in amps, and power in watts.
9Current = XXX amps equal to actual load.
10Power = XXX watts actual power.
*Step = each momentary step of up arrow key.
WARNING: Prevent electrical shock. Disconnect the
power supply before beginning installation. Failure to
follow these instructions could result in serious personal injury, death, and/or property damage.
6.10.4Corrective Action – correct the wiring or a faulty
device. If a signal is good with a signal generator then
the inter-connection wires are good and the sensor is
bad. In the case of RTD’s a substitute 100 OHM resistor will isolate a problem to the sensor.
Power board readings may be confirmed by a separate clamp-on line current readings, line voltage reading, and calculations for watts.
DANGER: Troubleshooting live control panels ex-
poses personnel to hazardous voltages. Electrical
troubleshooting must only be done by a qualified electrician. Failure to follow these instructions could result
in serious personal injury, death, and/or property
damage.

(relay coil energized) and a “0” = off. Toggle output
with a numerical key to match the output #.
6.12.3Interpretation – this is an output forcing operation to
allow checking of wiring and the connected device.
Since some outputs are normally closed the following
must be observed.
6.12.6Exit – press CLEAR and ENTER. All forced outputs
are cleared.
6.13PRE-DETERMINED FAULT AND FAULT CONTROL
6.13.1Predetermined Fault – a software timer known as a
watch dog times out upon a software or CPU failure
and shuts down in a predicable manner. LED CR6 on
the I/O board turns on and all outputs are turned off.
OIP board components are now used to determine
the state of all relays according to LOGIC installed by
the factory.
6.13.2Fault Control – operates as follows:
A. Press START-STOP key for stop.
B. Press AUTO-HAND key for HAND.
C. Enable pump/s as desired. (Press PUMP keys) to
run upon control failure.
D. Press AUTO-HAND key for auto. Press START-
STOP key to start.
E. Upon a CPU or software fault the unit will revert
to pumps selected in C above.
If power is momentarily interrupted the unit will return
to the same “hand” operation as before provided
pump keys were not pressed while the power was off.
6.14PROTECTION
6.14.1Analog inputs – the analog inputs provided on the
Technologic 350 must be wired according to the
wiring diagram that shipped with the unit.
6.14.2Protection – all analog inputs are protected from high
voltage, crossed wiring, etc. A 1 AMP fuse (F1) fast
acting 3AG located just above relays K6, K7 and K8
protects all analog inputs up to 600V (in error only). A
sustained fault may blow this fuse and burn out the
input resistors. They are located just below terminals
J3 and are numbered R3, R4, R1 and R2 for channels
1, 2, 3 and 4 respectively.
6.14.3Field Repair – resistors R1, R2, R3 and R4 plug in and
are easily replaced.
Correlate output terminals to the wiring diagram for actual practice.
NOTE: It is important to view status on the display before any state is changed.
This shows the actual output state of the program as it was presently running.
CAUTION: Do not trigger outputs unless the resultant
action is known. Do not trigger all outputs on at one
time or trigger at random. Failure to follow these instruc-
tions could result in property damage and/or personal
injury.
WARNING: Electrical shock hazard. Multiple
power sources. The off position of the HAND-OFFAUTO switch does not disconnect all of the power
sources in the Technologic panel. All power sources must
be disconnected prior to entering the control panel.
Failure to follow these instructions could result in serious personal injury, death, and/or property damage.

charge static electricity.
WARNING: Electrical shock hazard. Multiple
power sources. The off position of the HAND-OFFAUTO switch does not disconnect all of the power
sources in the Technologic panel. All power sources must
be disconnected prior to entering the control panel.
Failure to follow these instructions could result in serious personal injury, death, and/or property damage.
D. With one hand only gently pry EPROM (chip U1)
up from its socket alternating from each end in
small increments. Use a small screwdriver. Do not
place free hand on OIP components. Ground free
hand if possible.
E. Insert new EPROM with all pins in the socket and
the notch oriented as chip U2 notch (adjacent
chip).
F. If done carefully the EEPROM will not be corrupted.
G. Turn on power. Enter user menu per 5.1.3 and
check special data for the job at hand.

kept closed, and the components kept dry.
APPENDIX B
ELECTRICAL WIRING AND CONTROL SETTINGS –
FINAL CHECK LIST
___ 1.Does the feeder line voltage correspond to the unit
voltage? Check the unit nameplate or motor terminal
WARNING: Electrical shock hazard. Inspect all elec-
trical connections prior to powering the unit. Wiring
connections must be made by a qualified electrician in
accordance with all apllicable codes, ordinances, and
good practices. Failure to follow these instructions
could result in serious personal injury, death, and/or
property damage.
connection.
___ 2.Are the feeder wires correctly sized for the load?
___ 3.Are the fuses correctly sized? They must not exceed
1.75 times the full load current of the motor. Usual
sizing is 1.15 to 1.5 times the full load current.
WARNING: Conduit grounds are not adequate. A
separate grounf wire must be attached to the ground
lug provided in the enclosure to avoid potential safety
hazards. Failure to follow these instructions could
result in serious personal injury, death, and/or property
damage.
___ 4.Is the unit properly grounded?
___ 5.Have all the power terminals in the control panel been
checked for tightness? This is imperative since stranded wires tend to “flow” and become loose after initial
installation.
DANGER: High voltage 3 phase power can kill.
Disconnect and lock power prior to servicing unit.
Failure to follow these instructions could result in
serious personal injury, death, and/or property damage.

APPENDIX F
POWER TRANSDUCER BOARD (PTB)
1.0GENERAL DESCRIPTION
The PTB is a B&G proprietary board designed to measure total RMS load current and line voltage for either
single or 3 phase systems. This data is entered into a
microcontroller to calculate true power. True power,
amps, and volts are transmitted continuously to the
Tech 350 OIP microprocessor. These values are then
used for staging and/or display.
1.1SAFETY
The PTB is an electronic board with high voltage. It
carries 3 phase voltage up to 600 volts. Do not touch
it. There are no manual adjustments on board. If it
should become defective, as described elsewhere in
this manual, replace it. Field repair is absolutely not
authorized under any circumstances.
DANGER: Troubleshooting live control panels ex-
poses personnel to hazardous voltages. Electrical
troubleshooting must only be done by a qualified electrician. Turn power off prior to opening control panel door.
Turn power offand confirm it is off with a voltmeter.
Lock out disconnect/s.
DO NOT:
– Touch PTB with power on.
– Move jumpers with power on.
– Wire with power on.
– Even think about modifications.
– Even think about repair.
Failure to follow these instructions could result in serious personal injury, death, and/or property damage.
1.5APPLICATION
The following is performed by the factory. However, if
a PTB is being replaced in the field the following must
be observed:
A. One common (to load) conductor must be run
through the doughnut.
NOTE: This conductor must not rest on the PTB components except for the current transformer. Arc the
wire, in order to bias it away from the PTB, before
inserting it in the current transformer. Secure in place
with wire ties.
B. Insert this conductor into the hole on the flat side
of the doughnut with the load side of the conductor coming out of the opposite side of the hole.
C. 3 Phase – connect all 3 phases to terminals of J1
marked AØ, BØ, and CØ. Do not use com. AØ
must also be the same phase as that inserted into
the doughnut. Which is AØ, BØ or CØ is arbitrary
but must be established to follow these rules.
Single Phase – connect the “hot” line to AØ only
and neutral to com. Again AØ phase must be the
same phase as inserted into the doughnut.
D. Move voltage jumpers J3 and J6 to a voltage as
close to actual as possible. Jumpers on J3 and J6
must match each other.
E. Move jumper J2 to next highest amp terminal
above total motor load in amps. That may run at
one time.
1.2CURRENT SENSING
This is accomplished by inserting one common power
conductor through a linear output Hall effect doughnut.
1.3VOLTAGE SENSING
This is accomplished with a resistor network and a
potential transformer. Maximum voltage level is 600V
RMS.
1.4CALIBRATION
Calibration is performed at the factory for all ranges of
current and voltage. This resides in the EEPROM on
board the PTB.
1.6PHASE CONSIDERATIONS
The PTB will perform well with delta or wye systems,
grounded or ungrounded. However, on 3 phase
grounded systems do not ground the com. terminal of
J1.
1.7MENU CONSIDERATIONS
A menu entry must be made as to whether this unit
will be used in a 3 phase or 1 phase system.
