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.

(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
6.0 Preface: 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.
6.1 TECHNICAL 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.
6.2 DIGITAL 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.
6.3 DIGITAL 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.
6.4 ANALOG 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.
6.5 MEMORY
6.5.1 The 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.
6.5.2 The 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.
6.5.3 The RAM chip is not replaceable and requires no maintenance.
6.6 CPU
The CPU does not require any maintenance, and can­not be replaced as a field repair.
6.7 POWER 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.
6.8 DIAGNOSTICS (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 READ ONLY – Digital Inputs
6.9.1 To Enter – press CLEAR key twice and then press SERVICE TEST key once only while in normal scroll.
6.9.2 Display – numbers 1 through 12 (implied) on the top line and status on the second line. Status is dis­played as a “1” for signal on and “0” for signal off.
6.9.3 Interpretation – compare the status shown to the fol­lowing terminals and the wiring diagram. For example, starter 1M “on” signal at J4 4 and 8 is display No. 3 and should be a “1” if the 1M starter is energized. Input
Input J4 Input No.

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.
6.10.4 Corrective 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.

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.
6.14 PROTECTION
6.14.1 Analog inputs – the analog inputs provided on the Technologic 350 must be wired according to the wiring diagram that shipped with the unit.
6.14.2 Protection – 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.
6.14.3 Field 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.

APPENDIX F
POWER TRANSDUCER BOARD (PTB)
1.0 GENERAL 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.
1.1 SAFETY
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.
1.5 APPLICATION
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.
1.2 CURRENT SENSING
This is accomplished by inserting one common power conductor through a linear output Hall effect doughnut.
1.3 VOLTAGE SENSING
This is accomplished with a resistor network and a potential transformer. Maximum voltage level is 600V RMS.
1.4 CALIBRATION
Calibration is performed at the factory for all ranges of current and voltage. This resides in the EEPROM on board the PTB.
1.6 PHASE 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.
1.7 MENU CONSIDERATIONS
A menu entry must be made as to whether this unit will be used in a 3 phase or 1 phase system.
