Technologic 350 Pump Controller
INSTALLER: PLEASE LEAVE THIS MANUAL FOR THE OWNER’S USE.
DESCRIPTION: Microprocessor based dedicated pump con­troller for constant speed pumping systems. The control panel includes the following components: microprocessor with EPROM chip, starters, overload protection, virtual H-O-A switches, optional short circuit protection and control transformer.
The microprocessor control consists of an operator interface with 2 line backlit display and membrane key pad, input/output board with 24V power supply, and microcontrolled kW transducer.
OPERATIONAL LIMITS: See the control panel nameplate for operating voltage, current draw, as well as information on the equipment to be connected to the control panel.

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.

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 working near the motor shaft. Failure to follow these
instructions could result in serious personal injury, death, and/or property damage.
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.
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.
