Preface
The following manual describes the new microproces­sor based Technologic 5500 Variable Primary Pump 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 and valve controller. This means that the hardware and software have been created for the control and diagnostics of pumps and valves 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 analog input protection of other members of the control family. In the event of a short circuit condition the current limit circuitry pre­vents failure of the analog input components.
This new controller has standard manual motor bypass switches when a Bell & Gossett automatic bypass is supplied. The manual motor bypass switches allow the user to de-energize the programmable logic con­troller and take manual control of the pumping system. This is helpful during system startup to confirm pump rotation and to purge air from the system prior to switching to automatic control.

ATTENTION BECOME ALERT!
YOUR SAFETY IS INVOLVED! FAILURE TO FOL­LOW THIS INSTRUCTION MAY RESULT IN A SAFETY HAZARD.
1.2.2 Safety Instruction Decal
Your Technologic 5500 Series Variable Primary Pump
and Valve Controller should have a safety instruction decal (part # S11550). If the decal is missing or illegible contact your local B&G representative for a replacement.
1.2.3
Motor Safety
Each motor must have a properly sized starter with
properly sized overload block to provide overload and undervoltage protection. Ground fault protection should be sized properly. Refer to local electrical codes for sizing and selection. Refer to the motor manufacturer's I.O.M. (Installation Operation Manual) for specific installation information. Even when the motor is stopped, it should be considered "alive" as long as its controller is energized.
The use of motor disconnect switches is acceptable. Consult the factory for proper interlocking with adjustable frequency drives, AFD's. See section 1.9.
1.2.4
Motor Control Equipment Safety
Motor control equipment and electronic controls are
connected to hazardous line voltages. When servic­ing 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.
1.3
Storage
For long periods of storage, the unit should be cov-
ered to prevent corrosion and contamination from dirt. It should be STORED in a clean, dry location between -20 and +60ºC. 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.
NOTE: EXTENDED STORAGE OF AFDs MAY
REQUIRE SPECIAL ATTENTION PRIOR TO START­UP. SEE MANUFACTURER'S I.O.M. FOR DETAILS.
1.4
Handling
Care should be taken to prevent damage due to
dropping or jolting when moving the Technologic Vari­able Primary Pump and Valve Controller. Transporta­tion damage should be brought to the carrier's atten­tion immediately upon receipt.
1.5
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.
1.6
Input Voltage
The Technologic Variable Primary Pump and Valve
Controller was factory set to operate on the voltage shown on the nameplate. Check the AFD nameplate for the proper input and output voltages before wiring the AFD.
The voltage tolerance is +10/-5% and phase to phase voltage must not have an imbalance greater than 5 VAC.
Section 1 - General

A grounding terminal is provided for a dedicated
ground wire connection. All provisions of the National Electrical Code and local codes must be followed.
1.8
Power Wiring
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.
1.9
Output/Motor Disconnect
It is necessary that any device that can disconnect
the motor from the output of the AFD be interlocked to the emergency shutdown circuits of the AFD. This will provide an orderly shutdown if the disconnecting device is open circuited while the AFD is in operation. Failure to provide this interlock may result in dam­aged components due to improper installation.

DP Switches
Differential pressure switches sense the increase in
pressure between the pump suction and discharge gauge taps. DP switches are used to determine whether a pump is running. Each switch should be wired from the normally closed contact.
1.12.2
AFDs
To monitor if an adjustable frequency drive is running,
it is necessary to wire from each AFD's normally open "run" or "on" contact.
For the Technologic Variable Primary Pump and Valve Controller to start and stop each AFD, it is nec­essary to wire to the remote start terminals in each AFD.
Additional wiring to each of the adjustable frequency drives may be required with certain types of con­troller programs. Refer to the wiring diagram for all connection points.
With certain bypass and control methods, it is neces­sary to disable an adjustable frequency drive from running. This is accomplished by wiring from the Technologic 5500 terminals to each AFD's interlock terminals. Should this wiring be required, any jumpers which may be found on the AFD's interlock terminals should be removed.
1.12.3
Analog Inputs
The Technologic 5500 control family has the capa-
bility to accept many analog inputs. Typically, all analog inputs must be 4-20mA and powered by the 24VDC power supply in the Technologic 5500. All shields must be grounded, only in the Technologic 5500, to prevent ground loops and improper signals.
To monitor system zones, it is not necessary for all analog inputs to be used. It is necessary, however, that all zone transmitters be connected consecutively starting with zone 1. Optional transmitters (i.e., other than zones) may be supplied.
CAUTION: Metal filings can create electrical short
circuits. Do not drill, saw, file or perform any opera­tion on the AFD conduit entry plate while attached to the AFD.
FAILURE TO FOLLOW THESE INSTRUCTIONS
COULD RESULT IN PROPERTY DAMAGE AND/OR MODERATE PERSONAL INJURY.
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 RESULT IN SERIOUS PERSONAL INJURY, DEATH, AND/OR PROPERTY DAMAGE.
WARNING: Prevent electrical shocks. Disconnect
the power supply before beginning installation.

1.12.4
Analog Inputs with External Power
The following steps describe the general procedure
for rewiring an analog input sensor when the sensor's power source is not the Technologic 5500 controller.
1) Turn off all power to the Technologic 5500 controller.
2) Refer to the appropriate controller wiring diagram that was shipped with unit. Locate the analog input sensors on the wiring diagram that will be rewired. They are labeled AI X.
3) Remove the 24 VDC positive (+) wire from TB 40 for the respective analog input sensor connection. This wire needs to be removed completely or ter­minated if used as a jumper. This will prevent any accidental contact with a negative (-) voltage source (i.e. control panel) and avoid becoming a short circuit. Care should be taken to ensure that 24 VDC positive (+) voltage is still provided to any remaining sensors that will be powered by the Technologic 5500 controller.
4) Remove the 24 VDC negative (-) wire from TB 41 for the respective analog input sensor connection. This wire needs to be removed completely or ter­minated if used as a jumper. This will prevent any accidental contact with a positive (+) voltage source and avoid becoming a short circuit. Care should be taken to ensure that 24 VDC (-) negative voltage is still provided to any remaining sensors that will still be powered by the Technologic 5500 controller.
5) Terminate the negative (-) wire of the sensor to TB 41 of the respective analog input sensor connec­tion. Terminate the positive (+) wire of the sensor to the terminal block which is connected to the positive (+) terminal shown on the Analog input card.
NOTE: Be certain that the power supplied to other
terminal blocks has not been interrupted! The wires that were removed in the preceding steps may have been used as jumpers.
1.12.5 Drive Speed Signals
Drive speed (follower) signals must be wired from the
Technologic 5500 Controller to each of the adjustable frequency drives. The AFDs must be configured to accept a 0-10 VDC speed signal with the minimum speed set for 30% (0 VDC) and maximum speed set for 100% (10 VDC). All shields must be grounded, only in the Technologic 5500, to prevent ground loops and improper signals.
1.12.6
Valve
The Valve must be configured to accept a 4 - 20mA
signal with the closed position set for 4 mA and the open position set for 20 mA. All shields must be grounded, only in the Technologic 5500, to prevent ground loops and improper signals.
1.12.7
Hardwire Communications
Hardwire communications refers to the capability of
the Technologic 5500 Controller to communicate with an energy management system. Standard communi­cation features such as remote start/stop and remote alarm indications are listed below.
1.12.7.1
Remote Start/Stop
Install a switch as indicated on the wiring diagram.
With the LOCAL-REMOTE-OFF switch in the REMOTE position, this contact closure will provide the start signal.
1.12.7.2
Remote Alarm Indication
A digital output rated 8 amps at 115V is supplied.
This output closes to indicate an alarm condition exists.
1.12.8
User Configurable I/O
The Technologic 5500 Controller comes equipped
with the capability to define the operation of any unused input or output signal. Refer to Section 4.3.9 for detailed information on the I/O Setup Menu.
WARNING: Prevent electrical shocks. Disconnect
the power supply before beginning installation.

Section 2 - Installation and Startup
2.1 Location
Install the pumping unit appropriately for ease of
inspection, maintenance and service. Observe local electrical codes concerning control panel spacing.
2.2
Installation of Skid Mounted Systems with
Factory Supplied Pumps
This unit is built to give you years of service if it is
installed properly with a suitable foundation.
2.2.1
Foundation
A base of concrete weighing 2-1/2 times the weight
of the unit is recommended. Check the shipping ticket for unit weight. Tie the concrete pad in with the finished floor. Use foundation bolts and larger pipe sleeves to give room for final bolt location. Place the unit on its concrete foundation, supporting it with steel wedges or shims totaling 1" in thickness. These wedges or shims should be put on both sides of each anchor-bolt to provide a means of leveling the base.
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.
FAIL-
URE TO FOLLOW THESE INSTRUCTIONS COULD RESULT IN SERIOUS PERSONAL INJURY, DEATH, AND/OR PROPERTY DAMAGE.
10
2.2.2
Grout
After the frame has been leveled and securely bolted
to the pad, a good grade of grout should be installed beneath the base. A suggested mixture for grout is: one part Portland Cement and two or three parts plain, sharp sand mixed with water until it will pour easily. Commercial grout mixtures with suspended iron particles are available. Wet the concrete base before pouring grout. To hold wedges or shims in place, allow the grout to flow around them and beneath the entire length of the base flange.
2.2.3
Closed System Safety Measures
Important:
Do not install and operate the Bell &
Gossett Technologic 5500 Variable Primary pump and valve controller in a closed system unless the system is constructed with properly sized safety and control devices. Such devices include the use of properly sized and located pressure relief valves, compression tanks, pressure controls, temperature controls and flow controls as appropriate. If the sys­tem does not include these devices, consult the responsible engineer or architect before making pumps operational.
2.2.4 Eccentric Increasers
Eccentric increasers can be used in the suction lines
when increasing the pipe size, with straight sides of the increaser on top to eliminate air pockets.
2.2.5
Pipe Support
Be sure to eliminate any pipe strain on the unit.
Support the suction and discharge pipes indepen­dently by use of pipe hangers near the unit. Line up the vertical and horizontal piping so that the bolt holes of the flanges match. DO NOT ATTEMPT TO SPRING THE SUCTION OR DISCHARGE LINES INTO POSITION. As a rule, ordinary wire or band hangers are not adequate to maintain alignment. It is very important to provide a strong, rigid support for the suction line. A saddle hanger is recommended.
2.2.6
Expansion and Vibration Absorbtion
For critical installations, equipment for absorbing
expansion and vibration should be installed in the inlet and outlet connections of the unit.
2.2.7
Lubrication
Before starting, all pumps and motors should be
checked for proper lubrication.
2.3
Putting the Unit into Service
2.3.1 Pump Rotation, 3 Phase Motors Only
It will be necessary to check for proper rotation for all
pumps in both variable speed and bypass. Run each pump in AUTO and then in BYPASS, if so equipped, and note the rotation in each.
If both rotations (AFD and bypass) are wrong, ex­change the wiring on two motor phases. If the rota­tion is incorrect in the AFD mode, but it is correct in the bypass mode, exchange the wiring on two of the AFD output phases.
If the rotation is correct in the AFD mode, but it is incorrect in the bypass mode, exchange the wiring on two of the bypass input phases.
NOTE: Changing phase at AFD input does not change
output phasing.
2.3.2
Joint Check
While the unit may be hydro tested at the factory to
internal quality standards, there may be some joints that are not pressure tested. Some joints may have been loosened, to allow for draining of the system, and not retightened. Thus, some joints may be loose due to system drainage or shocks during the ship­ping process. All flanged joints are to be checked for tightness and proper torque of the flange bolts prior to filling the system with fluid.
DANGER: The heating of water and other fluids
causes volumetric expansion. The associated forces may cause failure of system components and releases of high temperature fluids. This will be prevented by installing properly sized and located pressure relief valves and com­pression tanks.
FAILURE TO FOLLOW THESE INSTRUC-
TIONS CAN RESULT IN SERIOUS PROPERTY DAMAGE AND SERIOUS PERSONAL INJURY OR DEATH.
CAUTION: Seal Damage may occur. Do not run
pumps dry. Fill and vent the pump volute prior to
operation.
FAILURE TO FOLLOW THESE INSTRUC-
TIONS COULD RESULT IN PROPERTY DAMAGE AND/OR MODERATE PERSONAL INJURY.
WARNING: Rotating shafts can catch loose clothing.
Do not operate the pump without all guards in place.
FAILURE TO FOLLOW THESE INSTRUCTIONS COULD
RESULT IN SERIOUS PERSONAL INJURY, DEATH, AND/OR PROPERTY DAMAGE.
WARNING: Failure to check all joints for tightness
and all flange bolts for proper torque could result in
leaks and/or flooding.
FAILURE TO FOLLOW THESE
INSTRUCTIONS COULD RESULT IN SERIOUS PER­SONAL INJURY, DEATH, AND/OR PROPERTY DAMAGE.
DANGER: High voltage 3 phase power can kill. Dis-
connect and lockout power prior to servicing unit.
FAILURE TO FOLLOW THESE INSTRUCTIONS WILL
RESULT IN SERIOUS PERSONAL INJURY, DEATH, AND/OR PROPERTY DAMAGE.
