PASTE ROLL HEIGHT MONITOR SAFETY INFORMATION CHAPTER 27 PASTE ROLL HEIGHT MONITOR SAFETY INFORMATION The Paste Roll Height Monitor uses a class laser to detect the height of the paste roll Warning and Caution labels Warning labels are located on the sender leg (lhs) as shown: Safety Warning Label CAUTION LASER RADIATION,DO NOT STARE INTO BEAM DIODE LASER, MAX OUTPUT 1mW CLASS II LASER, WAVELENGTH 635 +/- 10Nm FDA Regulation “21 CFR Parts 1040.10 and 1040.11" Caution Notice Manufacturer: DEK, 11 Albany Road, Weymouth, Dorset, DT4 9TH Country of Manufacture: Germany Complies with 21CFR1040 with deviations pursuant to Laser Notice 50 Manufacture Date: Month: Year: Manufacturer’s Label The labels include: Chapter Issue Feb 11 • The safety warning label; radiation (Laser light source present) • The manufacturer’s label; date and place of manufacture and the applicable safety standard • Caution notice; specific safety instruction - not stare into light source 27.1 PASTE ROLL HEIGHT MONITOR MODULE OVERVIEW In addition, the following general safety labels are presented throughout this chapter WARNING RADIATION RISK OF INJURY TO THE EYES DUE TO LASER LIGHT BEING PRESENT IN THE VICINITY OF THE LABEL DO NOT LOOK AT THE LIGHT SOURCE OR REFLECTIONS FROM A SURFACE CAUTION EQUIPMENT SERVICING THE LASER DOES NOT CONTAIN USER SERVICEABLE PARTS OPENING THE UNIT COULD CAUSE MIS-ALIGNMENT OF THE LASER, THIS MAY MAKE THE EQUIPMENT DANGEROUS TO OPERATE CAUTION LASER CONTROLS AND ADJUSTMENTS USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE SPECIFIED HERIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE MODULE OVERVIEW Purpose The optional Roll Height Monitor detects the height of the roll of the print medium, if insufficient height of the print medium roll is sensed an automatic paste dispense operation is initialized Elements The Roll Height Monitor consists of the following: Operation 27.2 • Roll Height Monitor Assembly • Voltage Regulator The Roll Height Monitor assembly is fitted to the machine replacing the front squeegee ‘I’ bar mount The front squeegee is fitted to the assembly in the same way as it fits the squeegee ‘I’ bar mount The laser light source is fitted to the left hand leg of the assembly and the light receiver is fitted to the right hand leg The light source and receiver are positioned such that the line of sight between them is in front and between 10mm - 16mm above the tip of the squeegee As the machine performs a print stroke to the rear, the height of the print medium roll in front of the squeegee is monitored between 50% and 90% of the print stroke If the receiver acquires light from the light source a paste dispense operation is initialized and an entry is written to the event log file If the entry in the event log equals or exceeds three, the tricoloured beacon displays red and an error message ‘Insufficient Print Medium Has Been Dispensed.’ The option to replenish the paste dispenser is given Chapter Issue Feb 11 Chapter Issue Feb 11 M37PL05 M37PL08 +24V US 0V Return +24V SW 0V Return +12V 0V Return Single Board Computer (SBC) or Motherboard PC USB NextMove ES (I/O Node 1) M36 Machine Control M36PL35 CAN Bus +24V US 0V Return +24V SW 0V Return +12V 0V Return NOTE The breaks in the CAN Bus chain reflect that additional I/O Nodes may be fitted, refer to Machine Control chapter for the complete CAN Bus chain M37 PSU Enclosure N3SK1 N3SK3 N3SK2 N10PL4 N3SK3 N10SK2 M DIG IN DIG OUT DIG OUT CAN Out DIG IN CAN DIG IN In DIG IN Print Carriage I/O Node Print Carriage CAN Out CAN In I/O3 Paste Dispense Stepper Node 10 N3PL8 N3PL8 N3PL10 N3PL10 N3PL11 N3PL4 N10PL1 9PL26 9PL27 N3PL44 N3PL44 9PL60 +12V Signal 0V 0V +12V SW +12V SW Signal 0V 9SE12 +24V Signal 0V Paste Pressure Solenoid 9SOL26 Paste Cartridge Tilt Actuator 9SOL27 Paste Cartridge Vertical Sensor 9SE14 Paste Cartridge Horizontal Sensor 9SE13 Paste Level Sensor 9SE15 Roll Height Laser Roll Height Sensor 9SE24 Paste Dispenser Home Sensor 9SE12 PASTE ROLL HEIGHT MONITOR ELECTRICAL SCHEMATIC ELECTRICAL SCHEMATIC 27.3 PASTE ROLL HEIGHT MONITOR MECHANICAL DETAIL MECHANICAL DETAIL Roll Height Monitor Assembly The Roll Height Monitor assembly consists a horizontal beam which is secured to the machine in place of the front squeegee ‘I’ beam Two legs attached at either end of the beam via THK linear bearings, house the laser light source and receiver Plastic wedges at the foot of each leg prevent damage to the stencil whilst the print stroke is being carried out The horizontal beam houses beam extensions which can vary the beam’s length from 421mm to 575mm to accommodate different size squeegees Each extension is secured within the beam by a cap headed bolt Width Adjustment Securing Screw (in positions) Paste Height Adjustment Securing Screw (in positions) Horizontal Beam THK Linear Bearing (in positions) Front Squeegee Mount Laser Transmitter A Nylon Screen Protector (in positions) View on Arrow A Showing Light Receiver Figure 27-1 Roll Height Monitor Assembly NOTE The paste drip tray must be removed before fitting the paste roll height monitor Voltage Regulator 27.4 The voltage regulator situated within the looms at the right rear corner of the machine The regulator provides the correct voltage to the roll height sensor Chapter Issue Feb 11 PASTE ROLL HEIGHT MONITOR DRIVES & SENSORS DRIVES & SENSORS Drives There are no drives associated with this option Sensors Chapter Issue Feb 11 Name Type Roll Height Sensor 9SE24 Control Card Functional Description MultiMove X11 Detects the laser light when the print medium is insufficient 27.5 PASTE ROLL HEIGHT MONITOR ADJUSTMENTS & SETTINGS ADJUSTMENTS & SETTINGS WARNING RADIATION RISK OF INJURY TO THE EYES DUE TO LASER LIGHT BEING PRESENT IN THE VICINITY OF THE LABEL DO NOT LOOK AT THE LIGHT SOURCE OR REFLECTIONS FROM A SURFACE CAUTION SOLDER PASTE AND SOLVENTS WHEN USING OR HANDLING ANY SOLDER PASTE OR SOLVENT FORMULATION THE MANUFACTURERS’ RECOMMENDED SAFETY PRECAUTIONS MUST BE STRICTLY ADHERED TO Setup Roll Height Monitor To enable the Roll Height Monitor carry out the following: Select Maintenance Select Machine Setup Select Options Change Roll Height Hardware to Fitted Change Roll Height Monitor to Enabled Select Back Select Back Select Back 27.6 Chapter Issue Feb 11 PASTE ROLL HEIGHT MONITOR ADJUSTMENTS & SETTINGS Roll Height Hardware Sets whether or not the Roll Height Hardware is fitted, options are: • Fitted • Not Fitted On Monitor Failure Sets the consumable action, options are: Roll Height Monitor Roll Height Monitor Width • Warn • Pause • Suspend Used to specify whether roll height monitor is to be used, options are: • Enabled • Disabled Used to specify the overall width of the roll height monitor assembly • Min -
