5 Chapter One Tape Loading Feeder Operation 1

6 Installing and Removing the LMG Module The LMG Module is a separate unit that works in conjunction with the LP Series label feeders. LMG Modules are interchangeable to allow easy changeover between different label stocks on the same feeder. Refer to the documentation provided with the LMG Module for more information. To install the LMG Module: 1. Pull the latch lever out on the LP Series Feeder and hold it in the out position (refer to Fig. 1-1). 2. Align the mounting pins on the bottom of the module with the mating holes on the module interface. 3. Push the LMG Module straight down until it seats flush on top of the module interface. LATCH LEVER ON LP SERIES FEEDER Fig Release the latch lever to lock the module in place (refer to Fig. 1-2). To remove the LMG Module: 1. Pull the latch lever out on the LP Series Feeder module interface. 2. Carefully pull the module straight up. 3. Release the latch lever. Fig. 1-2 Note If the LMG Module does not seat flush to the interface housing, carefully remove and inspect both the LMG Module and the top of the interface for dirt or other foreign materials that could prevent the LMG Module from seating properly. 1-1

7 Tape Loading Step 1 Install the label reel by placing it onto the Reel Holder at the Tail Section end of the feeder. Make sure the liner feeds from left to right out the top of the reel. Pull the liner from the reel in the direction shown. Fig. 1-3A Fig. 1-3B 1-2

8 Caution Before threading the liner through the Label Feeder, always remove enough labels from the lead end of the liner so it can be threaded through the LMG Module without having any labels pass through the lower part of the LMG Module. If labels are left on the liner, the hard turns of the liner path through the LMG Module will cause the labels to dislodge from the liner inside the unit, which can create potential feed problems. Step 2 Remove approximately 12 in. of labels from the lead end of the liner to thread the liner through the LMG Module. Insert the liner into the feeder by passing it under the first guide roller. Then thread the liner into the LMG module. GUIDE ROLLERS LMG MODULE NOTE: Complete tape path shown in illustration. Refer to following steps for details of tape loading. Fig

9 Step 3 Press down the Peel Edge Pivot Lever on the LMG Module until the mechanism locks open. PEEL EDGE PIVOT LEVER Fig. 1-5 Note The LMG Module used for illustrations in this manual is fabricated with multiple rollers. However, each LMG Module is custom designed for a specific label and may have one or more rollers, one or more platforms, or a combination of rollers and platforms. Step 4 Feed the tape liner under the Tensioner and down between the Peel Edge and the first roller or platform of the LMG Module (refer to Fig. 1-6). TENSIONER PEEL EDGE ROLLERS Fig

10 Note For proper alignment, the Drive Assembly Handle should be unlocked and remain in the unlocked position until all liner loading operations are complete. Step 5 Open the Drive Assembly by moving the handle into the vertical position, which will open the Rollers. Thread the liner under the guide roller and then between the open rollers on the Drive Assembly. Close the Drive Assembly Handle. The loading operation is now complete. HANDLE GUIDE ROLLER Fig

11 Operation STATUS LIGHT FORWARD FEED CENTER BUTTON REVERSE FEED Control Functions STATUS LIGHT Flashing Red = Feeder not ready to run. It can be manually forward or reverse fed, but not run in automatic mode. Steady Green = Feeder Operational FORWARD FEED Press and hold to advance liner with labels until released. Fig. 1-8 CENTER BUTTON Press and release to auto-advance and recover from an error condition (flashing red). FIRST LABEL PEEL EDGE REVERSE FEED Press and hold to retract liner with labels until released. Operation Sequence Fig. 1-9 Fig FIRST LABEL CENTERED ON PICK POINT Power up the feeder with the Hover- Davis power supply or the pick and place machine. There will be a three second homing sequence. On startup, the feeder auto-advances the label to the Pick Point. When the label is in position, the Status Light changes to solid GREEN. Once the light is GREEN, the feeder is operational. The Status Light turns off during advance. Once a label is detected, the feeder stops advancing and the Status Light again turns GREEN. If a label is not detected by the end of the programmed time delay, the feeder stops advancing and the Status Light flashes RED. 1-6

12 Chapter Two LMG Module Timeout Delay 2

13 Programming the Timeout Delay Timeout Delay Chart YYYY Delay All label feeders have a timeout delay to make sure the feeder will advance the label to the Pick Point but will not continue advancing indefinitely if there are missing labels on the label stock. If the feeder reaches the programmed timeout delay before a label has reached the Pick Point, the feeder will resort to an error mode and will need to be reset by pressing the Center Button. This feeder timeout delay is programmable and should be set according to the specific label fed by the LMG Module being used. To set the timeout delay, find the model number located on the serial label of the LMG Module. Note the last four digits (YYYY) as shown below. LMG02-XXXXYYYY Using the chart to the left, match the last four digits of the LMG Module model number to the corresponding four digits on the chart. The number to the right of this is the corresponding offset that needs to be used to program the timeout delay. If the four digits do not appear on the chart, select the closest, next highest value. (For example, for a model number ending with 0728, use 0800 on the chart.) Note The Timeout Delay Chart assumes in. [3mm] spacing between the consecutive labels on the liner. Label spacing of 0.25 in. [6mm] or greater requires adding (1) to the offset recommended on the chart. The maximum timeout offset delay that can be programmed is (20). 1. Power up the feeder either on the platform machine or an offline power supply. POWER SUPPLY TRIGGER BOX Fig

14 2. Hold down the Center Button on the Control Panel until the Status Light turns Yellow. Release the button. The feeder is now in Program Mode. Fig Release the Center Button and count the number of times the Status Light blinks Green. The number of blinks equals the currently programmed Timeout Delay. Fig Press the Forward Feed button to increase the Timeout Delay (refer to Fig. 2-6) or press the Reverse Feed Button to decrease the Timeout Delay (refer to Fig. 2-7). Each press increases or decreases the delay by a count of one. Fig. 2-6 Fig

15 1. Verify that the correct timeout has been set by pressing and releasing the center button and counting the number of times the Status light blinks green. The number of blinks equals the Timeout Delay. Fig When the Timeout Delay is correctly programmed, press and release the Forward Feed and Reverse Feed buttons simultaneously to exit programming mode.

16 Chapter Three Maintenance 3

17 Troubleshooting To inspect and repair the LP Series Label Presenter and LMG Label Module, follow the instructions listed in the chart on the following page. Warning Do not operate the feeder with the Covers removed. Caution When replacing parts and securing Covers, make sure all Cables are securely routed to avoid pinching and feeder damage. Caution When the feeder is loaded into the placement machine, the feeder MUST BE latched or locked into position. Caution Do not modify the feeder in any way 3-1

19 Preventive Maintenance Note For proper operation, the preventive maintenance steps shown below should be performed at least every three months. Actual operating conditions may require more frequent cleaning. Note Refer to "Chapter 4 - Parts Lists" for exploded-view drawings showing the locations on each of the items described below. If replacement is required, refer to the appropriate procedure in the balance of this chapter. Drive Assembly Advance the feeder and examine the [191A-S75] Intermediate Gear as it rotates. If there is no lube present on the gear teeth, apply a small amount of Super Lube to the teeth of the gear as it rotates. Do not over lube the gear or allow lube to touch the drive pulleys as this may cause slippage in the drive system. (Refer to Drive Roller Disassembly procedures on Page 3-4.) Note Super Lube is a general purpose synthetic-based lubricant with Teflon available from Loctite Corp. (Item #82325). Label Roller(s)/Label Platform Inspect the roller(s)/platform for deposits of adhesive from the label backing. If found, wipe away with a clean, soft cloth. All Components Touching Tape Path Using a clean, soft cloth (or clean compressed air), wipe (blow) away any contamination from the tensioner, peel edge, drive pulleys, and dispenser drive. Drive Rollers Clean the drive rollers of any adhesive buildup. (Refer to Drive Roller Disassembly procedures on Page 3-4.) 3-3
