IDENTIFYING LOGIC+ MODELS The Logic+ platform Biosafety Cabinet can be identified readily by several external features, as shown in Figure 1-1: Serial number beginning with 1303xxxxx Flush-mounted electrical outlets and covers. Color LED display.
SERIAL NUMBER TAGS The model/serial number tag is located on the bottom outside edge of the right corner post. A second tag is located on the front of the electronics module on the top of the unit. This tag includes the unit’s operating voltage and amperage. The model and serial numbers of each unit are also recorded on the unit test report attached beneath the front dress panel.
LOGIC+ MODEL NUMBERING SYSTEM Logic+ units’ model numbers define the configuration of the cabinet. The first five digits define the unit's configuration, while the last four are assigned based on the unit's options and electrical configuration.
Logic+ Data Plate The Logic+ Data Plate contains much of the information required to certify the unit. Information on the plate includes nominal inflow and downflow velocity settings, a description of how to establish the downflow grid and the secondary inflow methodology are also included on the data plate, as shown below. The plate is located in the upper left corner of the dress panel.
Final Inspection and Test Report Form A copy of the Final Inspection Test Report is attached to the blower plenum cover, beneath the front dress panel. The report contains initial setup information on inflow and downflow velocities, and the initial blower torque setting.
Theory of Operation This section offers a brief overview of the theory of operation of the Logic+. Airflow Patterns Figure 1-8 All Logic+ Type A2 cabinets meet the airflow requirements of ANSI/NSF Standard 49:2012. Approximately 55-60% of the air in the cabinet is filtered and recirculated, while 40-45% is filtered and exhausted. ALL Logic+s feature intrinsically safe designs, jacketing contaminated positive pressure areas with negative pressure zones.
ECM Motor The modern Class II Biosafety Cabinet was developed in the early 1960’s as a result of the increased availability of High Efficiency Particulate Air (HEPA) filter technology. The motor of choice at the time to drive the cabinet’s blower was the Permanent Split Capacitor (PSC) type. At the time, the PSC motor offered manufacturers an inexpensive power source whose speed could be electronically controlled to allow for airflow adjustment as the HEPA filter(s) loaded.
Controlling the motor’s operation with a microprocessor adds numerous advantages. Motor speed can be efficiently controlled across a speed range that would damage or destroy a PSC motor. Given enough microprocessor memory and power, the manufacturer can program in any number of userselected programs controlling motor speed, power and even direction of rotation.
The Logic+ has three circuit boards. The ECM microprocessor and power supply board, located in the end of the ECM, the control board on the right side wall, shown in Figure 2-5, and the power supply board assembly, located in the electronics module, as shown in Figure 1-13. Figure 1-13 UV Relay Light Relay Outlet Relay The Logic+ also has an optional contact/RS232 board.
Section Two – Installation Requirements This section offers an overview of site requirements and how to prepare the unit for operation. Prerequisites Before you install the Logic+, you need to prepare the site for installation. Examine the location where you intend to install the cabinet. You must be certain that the area is level and of solid construction. In addition, a dedicated source of electrical power must be located near the installation site.
Location Requirements Note: The biosafety cabinet should be located away from traffic patterns, doors, fans, ventilation registers, fume hoods and any other air-handling devices that could disrupt its airflow patterns. All windows in the room should remain closed. Figure 2-1 shows the preferred location for the biosafety cabinet.
Exhaust Requirements Type A If you intend to connect the biosafety cabinet to the optional VentusTM Canopy Connection Kit, first examine the location to ensure that it accommodates the cabinet’s exhaust duct. The area directly above the cabinet’s exhaust port should be clear of structural elements, water and utility lines, or other fixed obstructions. There should be enough clearance to accommodate a 10-inch diameter duct.
Electrical Requirements The biosafety cabinet models have the following electrical requirements: Table 2-1 Model # Requirements All 3-& 4-foot Type A ending in -00 All 3-& 4-foot Type A ending in -10 All 3-& 4-foot Type A ending in -20, 30, 40, 50, 60, 70 115 VAC, 60 Hz, 12 Amps 100 VAC, 50/60 Hz, 12 Amps 230 VAC, 50/60 Hz, 6 Amps All Type B2 ending in -00 All Type B2 ending in -10 All Type B2 ending in -20, 30, 40, 50, 60, 70 115 VAC, 60 Hz, 12 Amps 100 VAC, 50/60 Hz, 12 Amps 230 VAC, 50/60 Hz, 6 Amps
Service Line Requirements All utility service lines should be ¼ inch O.D., brass, copper, or stainless steel, and equipped with an easily accessible shut-off valve. If the service line pressure exceeds 40 PSI, it must be equipped with a pressure regulator to reduce the line pressure. Note: The use of flammable gases or solvents should be avoided in the biosafety cabinet. Open flame in the cabinet will disrupt the laminar airflow in the cabinet and may damage the HEPA filters.
Section Three – Installation Now that the installation is properly prepared, you are ready to inspect, install, and certify the Logic+ biosafety cabinet. This chapter covers how to: Unpack and move the biosafety cabinet. Install the cabinet. Connect the electrical supply source. Connect the service lines. Connect to an exhaust system (optional for Type As).
Unpacking the Biosafety Cabinet Carefully remove the outer carton and inspect the cabinet for damage that may have occurred in transit. If the biosafety cabinet is damaged, notify the delivery carrier immediately and retain the entire shipment intact for inspection by the carrier. Note: United States Interstate Commerce Commission rules require that claims be filed with the delivery carrier within fifteen (15) days of delivery. Do not return goods without the prior authorization of Labconco.
Moving and Lifting the Cabinet Move the cabinet, attached to its pallet, by using a floor jack, or a furniture dolly underneath the unit. DO NOT move the cabinet by tilting it onto a hand truck. When lifting the cabinet DO NOT lift the cabinet in the middle front area of the hull. Lifting here may bend or distort the bottom of the cabinet, causing damage to the unit. Installing the Biosafety Cabinet on an Existing Work Surface Note: The biosafety cabinet is very top heavy.
Table 3-1 Width 3' Base Stand w/Feet Model # 3401003 4' 3401004 5' 3401005 6' 3401006 Manual or Electric Hydraulic Lift Base Stands These base stands offer infinitely adjustable height between 25.5 and 33.5 inches (648 to 851 mm), giving a cabinet work surface height of 28.0 to 36.0 inches. The height is adjusted either by a manual (hand crank) or electric pump that drives hydraulic rams in the legs of the stands.
Connecting the Biosafety Cabinet to Utility Service Lines Note: Some models have a solenoid valve connected to the service valve on the right side, rear position. The solenoid prevents gas from flowing to the service valve when the unit blower is off. It is the only service valve position that can be fitted with a solenoid valve. Connect the gas service to the solenoid valve.
Optional VentusTM Canopy Exhaust Connection Certain applications such as working with odorous products or volatile toxic materials will require the connection of the biosafety cabinet to an exhaust system. Note: The canopy connection, also referred to as a thimble or air gap connection, allows single or multiple biohazard cabinets to be connected to an exhaust system.
Optional Vacu-PassTM Cord & Cable Portal Use Note: There must be enough clearance to pass the cord or cable between the Logic+’s exterior dress panel and any obstruction. Note: Some Vacu-Pass components and the cord or cable passing through it may become contaminated during use of the cabinet. Ensure all potentially contaminated components are surface decontaminated before handling or removal from the cabinet. 1. Remove the grommet from the liner side wall.
Drain Valve Installation In order to prevent damage during shipping, the drain valve assembly has not been installed. If desired, the valve should be installed after the cabinet is in its final location. To install the valve assembly, follow these steps: Note: The work surface is heavy. Use caution when handling it. 4. Lift the work surface out of the biosafety cabinet by lifting on the knobs at the front of the work surface. Steady the work surface while pulling it straight out the front of the cabinet. 5.
Section Four Initial Operation of the Logic+ This section will take you through the steps to begin initial operation of the Logic+, with an explanation the controls, display and options, in order to prepare the unit for its initial certification. System Reset Switch The biosafety cabinet has a system reset switch for resetting its microprocessors. The switch is located on the front of the electronics module, on top of the cabinet, as shown in Figure 4-1.
Information Center The Information Center is an LCD display located on the right side wall at eye level. When the blower is started, the words “please wait” will be displayed, as shown in Figure 4-2. After approximately 90 seconds, the display will switch to normal operation. The display provides a clock, the remaining filter life, the cabinet’s current status, inflow and downflow velocities (if equipped with the optional airflow sensor), as shown in Figure 4-3.
Alarm Screens Sash is too high The sash is open too far for safe operation. Airflow Alert The airflow patterns in the cabinet have changed, resulting in a sudden change in the motor speed. This is most likely due to a blockage of the grille or the exhaust filter outlet. It may also be caused by removal of the work surface while the cabinet is in operation.
Operating the Sliding Sash The counterbalanced, anti-racking sash mechanism requires only a few pounds of force to move the sash up or down. You can open or close the sash smoothly with one or two hands positioned on either handle. The sash position alarm and safety interlock system senses the sash position and acts appropriately. The biosafety cabinet has been programmed to operate at either an 8-, 9, 10- or 12-inch (203-305 mm) sash opening, depending on model.
The Logic+ Touchpad The touchpad of the Logic+ is shown in Figure 5-6. Take a moment to get familiar with the buttons, their locations and functions. Also familiarize yourself with the display located on the right side wall. The display will report system functions, such as filter capacity, timer displays, alarm or error messages, as well as icons that illuminate when cabinet functions such as UV light and blower are operational. Figure 5-6 Blower Button – Starts or stops the cabinet blower.
Navigating the Logic+ Menu Screens MyLogicTM allows you to use the Smart-Start or Night-Smart features that activate functions automatically when the sash is opened or closed.

RS-232 Connection Kits RS-232 Kit 3858310 (9 Pin), 3858311 (25 Pin) The kit contains the RS-232 PCB (P/N 3402200), the attaching hardware and connecting cables to install the PCB inside the electrical control box (located on top of the Logic+). Picture 1 shows an electrical control box with the Logic+ RS-232 PCB installed.
2) Locate the black square connecter labeled as J2 and the white connector labeled as J3 on the RS-232 PCB, see picture 3. These two connectors show through the electrical control box as shown in picture 1. Connector J2 is the RS-232 PORT connector. Connector J3 is the ALARM CONTACT connector. Also note the location of the J1 connector for later use.
4) Locate the internal RS-232 cable (P/N 3432000) included in the kit and connect it between the RS-232 PCB J1 and the Transition PCB (P/N 3431500) J6 as shown in picture 5. Picture 5 5) Re-secure the electrical control box to the top of the Logic+. 6) Connect the computer interface cable (P/N 7537800 – 9 pin or P/N 7537801 – 25 pin) included in the kit to the RS-232 PCB J2 connector, and connect the other end of this cable to a 9-pin or 25 pin serial input of a computer.
Using the RS-232 Receptacle The operation of the Logic+ Biological Safety Cabinet (BSC) can be monitored using a computer connected to the RS232 receptacle located on the top electrical box of the Logic+. The computer monitors the Logic+’s operation, but cannot control the operation of the Logic+. Connection for Computer Interface Check your computer to see which type of RS232 serial port is provided. Use one of the two connecting cables listed below: 1.
OPTIONAL LOGIC+ RS-232 DATA OUTPUT Here is the RS-232 output for the Logic+. As is standard for all Labconco units, the data is limited to 80 characters, including spaces, etc.
There are several commercially available software packages, which can read RS232 data and enter the data into a computer program such as a word processor (to create a text file) or spreadsheet (to tabulate and plot the data). Consult your laboratory supply dealer regarding the latest software available.
6. When the Logic+’s main power switch is on, the data will be transmitted and updated at the time intervals selected by the user. Logic+ Relay Contact Outputs: When equipped with the optional RS-232 contact kit board, Labconco Logic+ Biosafety Cabinet (BSC) models are provided with two (2) dry relay contacts to allow connection to an external monitoring system, or to switch other air handling units “on” when the Labconco unit is turned on.
Generally, the Labconco provided contacts can switch very low amounts of electrical current, so to control high power, line-operated devices, the Labconco contacts must be used to control yet another set of contacts that are rated for the actual load being switched. The wiring diagram indicates that the “BLOWER ON” contacts are located at J3 - pins 3 & 4 while the Airflow Alarm contacts are located at J3 - pins 1&2. Relay Contact #1 …….
The next diagram shows an example of using an AC powered coil, so the +12V supply from the Logic+ is not used. The Hasco HAT 903 relay series offers a 120VAC coil that requires only 16mA AC current as well as a 230VAC coil that draws only 9mA. The alternate circuit that uses an AC mains rated coil voltage is shown below – it does not utilize the FUSED+12V and CIRCUIT COMMON from the Labconco Logic+. Note: A W199 Magnacraft Series relay can switch up to 300Vac @ 40 Amps……….
The final diagram shows a connection for a 3-phase powered blower. In this case, a 12 VDC relay coil is used, and it gets its power from the Logic+.
Relay Contact #2……the “airflow error” contact This set of contacts (dry contacts pins 1 & 2 of J3 on the electrical enclosure, and the ORANGE wires on Labconco harness P/N 3432300) will indicate when the Logic+ has detected an airflow error, as described by the conditions below: Type of Logic+ unit All Labconco Logic+ Cabinets Alarm Condition Sash out of position LCD display message SASH TOO HIGH Airflow Error dry contacts No Response Motor RPM has shifted abruptly HEPA Filter approaching end of life—20
Section Nine – Miscellaneous Troubleshooting Refer to the following table if the Biosafety Cabinet fails to operate properly. If the suggested corrective actions do not solve the problem, contact Labconco for additional assistance. PROBLEM CAUSE CORRECTIVE ACTION Cabinet blower and lights won’t turn on Unit not plugged into outlet Plug the Biosafety Cabinet into appropriate electrical service.
