MIB-100 Special Features
The duration of each inspection interval is determined by the length of time that a particular color appears on the screen and finishes with an audio signal. The duration for each inspection can be altered in 0.1-second increments by the supervisor. The operator simply touches a button on the operator interface to begin the inspection process. The operator interface indicates when the inspection interval has expired by changing color. At the completion of the inspection cycle the inspector can record whether the last sample passed or failed the visual inspection. The PLC will keep the total number of containers Accepted, Rejected and total number of inspections performed. The supervisor can reset the data accumulation at the beginning of a new tray, batch or shift.
Figure 1. MIB-100DLC Key Components of Production Model
The MIB-100DLC offers the latest design configuration in the product line. The system is based on the standard MIB-100™ framework with several unique features. The "D" option refers to a digital control added to the PLC that allows the user to change the light intensity within the inspection volume by simply entering desired value on the operator interface. This feature is useful when inspections mandate different intensity levels for different products. The user can change from 2000 Lux to 6500 Lux with a few entries on the keypad. There is an optional "Programming Selector Switch" mounted behind a locked door to prevent unauthorized light intensity changes.
The "LC" option refers to the addition of light curtains in front of the White and Black backgrounds. The LC option will automatically start the countdown of the PLC Pacer function when the inspection holds the product in the inspection volume. If the product is removed prematurely from the inspection volume prior to reaching the zero time of countdown timer then the inspection cycle must begin again before moving to the next step of the sequence. The LC option requires that the product be be positioned in the inspection volumes for the proper durations, thus improving inspection consistency. This option can be used in combination with the 2-position footswitch to record Pass/Fail count of containers, useful in the reconciliation of defective units.
The MIB-100™ is fabricated with an anodized aluminum framework and black polycarbonate panels. The panels have a dual purpose; first to shroud the inspection samples from ambient light and second to insure the proper background is available for the inspection. The electronic components necessary for operation are included as part of the standard MIB-100™ system configuration, including the lighting control systems (with feedback circuitry), the Operator Interface (visual display), the electronic pacer system and the LED visual pacer indicators. The system can be ordered with the standard curved front Corian© armrest, optional straight front Corian© armrest or optional curved front stainless steel armrest. The placement of the Operator Interface can be selected from Left, Center or Right sides of the armrest.
NOTE: The lamps selected for MIB-100™ provide approximately 6,000 - 10,000 hours of life1 in which the intensity maintains an acceptable output level. The standard operating procedure requires that the lamps be changed at least once a year. Normally the lamp change is scheduled during the July or December shutdown period. It should be noted that all lamps provided by Phoenix Imaging are short tested, burned in for at least 100 hours and then measured to obtain the lamps initial output intensity and given a unique serial number. When a Phoenix Imaging Manual Inspection Booth is manufactured all the lamps are matched to specific output, i.e. foot-candle. The initial lamp output is recorded on the manufacturing label so that the lamps can be replaced with lamps of the same output when necessary. This reduces the time required during the calibration process, often no adjustments are required! Phoenix Imaging stocks thousands of biax lamps for MIB customers and offer same day shipment if ordered before 2:00 pm EST.
Available MIB-100™ Options
There are a number of optional components that can be added to the MIB-100™ to aid the inspector and make the inspection task more comfortable.
1) The "Visor Kit" offered on MIB-100™ Version 2.3 has been superseded with the "Top and Bottom Blind" option on MIB-100™ Version 3.1 and above. The Top and Bottom Blind Option prevents the inspector from direct viewing of the illumination sources or bright interior surfaces when the lamps are positioned close to the front of the booth. There is minimal decrease in light intensity in the inspection volume.

2) The MIB-100™ booth can be raised or lowered by using the booth hydraulic leveling kit to increase the center line on the inspection area by 12 inches, helpful when booths are shared with inspectors of different statures. This is an electric assist unit so with the push of a button will raise or lower the booth to the perfect height for each inspector! The pump assembly is covered with a stainless steel shroud as illustrated in Figure 3.

3) There is an audible alarm option that will provide audible signals for pacing operations as well as the standard LED pacers. The audible alarm can be turned on or off in software. There is a volume control built into the audible alarm to adjust the level.
4) The optional Side Shelves Kit is very useful when the MIB-100™ is used for high volume production work. The optional stainless steel side shelves for in-process product flow are fabricated to hold customer product trays. The side shelves can be ordered in fully adjustable or fixed configurations. The fully adjustable side shelves have articulated joints that allow the trays to oriented in the most comfortable position for the individual inspectors. The arms are articulated and the joints allow the shelves to be positioned in almost an infinite number of ways. The side shelves are designed to fit the size of the customer holding trays.

Figure 4 above illustrates the adjustment handles used to raise/lower and rotate the shelf support arm. No external tools are required to make the adjustments. When the handles contact the wall or structure simply lift them toward the hex head screw and rotate them to a new position.
5) The Plastic Catch Basin is used to protect the bottom mirror when the operator is inspecting large or heavy containers. The trays holds 0.5 liters of fluid and will prevent protect from entering the inspection booth in the event of an accident. The Catch Basin is constructed of Acrylic plastic for durability and it will not impact the light intensity. It is easy to clean with soapy water or IPA wipe.

6) The foot switch option is use to start the inspection cycle in place of touching the operator screen. It heavy duty construction of this dual actuator foot switch is designed for millions of cycles. There is a raise ridge between the two actuators to prevent accidental contact. The foot switch has a 2 M cable and quick disconnect to the bottom of the booth.
7) New Stainless Steel Armrest is available with or without Side Shroud Covers! (See Figure 1 for an example of the SS Armrest).
8) Top Shroud with adjustable speed cooling fans. This option is useful when the inspection booth will be used in an environment in which the light is not controlled well. The Top Shroud minimizes the effects of ambient lighting on the inspection process. To keep the inspector comfortable there are dual fans with a speed control.

Illumination System Considerations
ILLUMINANCE: (old term: ILLUMINATION)
Definition: (density of luminous flux on a surface)
FC = Lux x .0929
LUX = FC x 10.76 - (ie: 550 FC = 5918 LUX)
1 - Lamp life depends on intensity during use. High intensity inspection requirements will have a shorter lamp life than low intensity inspection requirements. Nominal use at 3750 Lux will provide approximately 6,000 hours of use.
