The Series 40 is LSI's Economical Performance line of stepper motor labeling heads. Series 40 includes models to accommodate 5" and 7" web widths, 12" and 16" diameter unwind rolls and user adjustable dispense speeds up to 1200" per minute. There is a standard Series 40 model designed to fit almost any labeling application. Field conversion kits are available to convert any Series 40 model into any other Series 40 model. An experienced technician can perform these conversions, in the field, in minutes. Custom configurations are available from the factory, to fit unusual applications. All models are available in either right hand or left hand configurations. They are designed to work with any of LSI's standard applicators.

Stepper Motor Drive
The Series 40 utilizes a 5 Phase Stepper Motor and onboard mounted stepper motor controller to provide maximum torque and precise speed control in a compact economical package.

A PLC is used to control all labeler and applicator functions and to generate pulses for the stepper motor controller. The PLC allows the flexibility of expandable I/O.

A bright, backlit LCD User Display allows the user to access information about the labeler. Performance Statistics gathered by the Series 40 include:·

• A Resettable Product Counter·
• A Resettable Label Counter·
• Current Throughput, in Products per Minute

The Series 40 includes 50 Recipe Storage Locations for easy set-up and repeatable product change over. Recipes include storage of all labeler and applicator parameters listed above.

Remote Display Mounting Kit
Series 40 labelers are shipped from the factory with the user display mounted in the front panel. In some installations, the front panel of the labeler may not be accessible. The Remote Display Mounting Kit allows the distributor or user to mount the end user display in a convenient location, regardless of the application.

Tip of Peeler Bar, Fiber Optic Label Sensor
The standard Series 40 label sensor is a fiber optic unit. The sensing end of the proprietary fibers are mounted in a block near the tip of the peeler bar, minimizing the effect of label converting variables on label stop position. This feature also allows the web advance if a label is missing from the web. The body of the sensor is mounted on the front plate of the labeling head. The body includes 10 LED's to indicate the status of the sensor. Two pushbuttons are included to change the mode of the sensor (leading edge or trailing edge) and to manually adjust sensitivity.

The standard sensor package includes an Auto-Teach feature that automatically adjusts label sensor sensitivity. Pressing a key sequence on the Series 40 user display causes an LED on the display to illuminate and advances the web automatically for 5 seconds. During this time, the label sensor learns the difference between the label and the web. When the web stops and the LED extinguishes, Auto-Teach is complete. Pressing Jog, to advance the web, ensures that label sensitivity has been set accurately. In testing, Auto-Teach accurately set label sensitivity on even the toughest labels.

The Series 40 is available in 5' wide and 7" wide versions. Both versions utilize LSI's rugged 3 point drive and nip mounting structure, to ensure that the drive and nip rollers remain parallel, through many years of 24 x 7 use.

5" Web Width Capacity
Models 41, 42, 43, 44 & 45 accommodate a 5" wide web.
7" Web Width Capacity
Models 46 & 47 are designed for webs up to 7" wide.

The Easy Thread Nip Roller Latch holds the nip open to facilitate threading the web through the drive.

12" Unwind Assembly with Single Roller Dancer Arm
The base Series 40 unwind includes 12" unwind disks, a single roller dancer arm and one idler roller. This configuration provides a short web path for easier threading. It is available in a 5" wide version only. This unwind works best with relatively short labels at moderate dispense speeds. This unwind is available on the Model 41.

The Series 40 can come equipped with a 14" diameter roll capacity. This is non-powered and is typically used for light, thick label material such a coupon, multi-layers, hang tab etc.

The Series 40 Alarm Package detects and annunciates the status of the label unwind reel and the label web. Sensors on the labeling head detect and alarm the following states:·

• Low Label·
• Label Out/Web Break

The alarm package includes a beacon light. The beacon illuminates to annunciate a Low Label condition (Low Alarm). The beacon will flash to indicate Label Out/Web Break (High Alarm).A photoeye located on the unwind assembly monitors the unwind reel and detects a Low Label condition. A convergent photoeye detects the presence of the web on the web drive roller. Absence of web on the drive roller indicates a Label Out/Web Break condition.

Much of the flexibility of the 40 Series is based on the field convertibility of any model into any other model. Using any of three field conversion kits, an experienced technician can perform the conversion in a matter of minutes

Double Dancer Field Conversion Kit, 5" Wide
The double dancer field conversion kit includes a two-roller dancer arm and an idler roller. The kit is used to covert a Model 41 to a Model 42 or 43. It can be used on both right hand and let hand heads.

Powered Rewind Kit
The powered rewind kit is a complete powered unwind assembly. It replaces the slaved unwind on Models 42, 44 and 46 to convert them into Models 43, 45 and 47 respectively. The 7" wide powered rewind is used on both 5" wide and 7" wide heads. It is shipped as a right hand assembly. It can be field converted to a left hand assembly, if required. Leads from the powered rewind connect directly to terminals on the Series 40 terminal strip.
