1 ITW Dynatec c Page 1 Revised 4/20/07 Description GEMINI TM DYNACONTROL TM HOSES Automatic & Manual Versions FOR DYNAMELT & DYNAMINI TM ADHESIVE APPLICATION SYSTEMS Adhesive supply hoses are electrically-heated, flexible conduits designed for the transfer of hotmelt material from an adhesive supply unit (ASU) to an applicator (head or handgun). Hoses are heated by resistance heaters which are wrapped around the hose core and covered with a hightemperature insulation. Hose temperature is regulated by the ASU s controller. A sensor located in the hose provides temperature information to the controller. GEMINI* DYNACONTROL hoses are 1000 psi (69 bar) hoses used to deliver hot-melt material from a Dynamelt or Dynamini ASU to an ITW Dynatec applicator (either a dispensing head or a hand-held applicator). These hoses provide through wiring for power, sensor and chassis ground in the applicator. All DynaControl hoses feature PT-100 RTD sensors. Gemini hoses are equipped with an extra heater and RTD sensor and a switch assembly which allows switching the hose s operation between the two. This provides a backup to eliminate downtime and allows time to plan for eventual hose replacment. On the Gemini Automatic hose, the switch is done automatically. On the Gemini Manual hose, the operator initiates the switch. Gemini hoses are water-resistant, made so by their seamless flexible sleeving, sealed end cuffs and liquid-tight electrical conduit and fittings.

MANUFACTURER PART NUMBER LENGTH INSIDE DIAMETER DATE OF MANUFACTURE SERIAL NUMBER Installation Instructions Before installing any hose to an ASU, make sure the ASU s power switch is OFF. DANGER HIGH VOLTAGE ITW Dynatec systems use electrical power that can be life threatening. Disconnect and lock out input power to the application system before connecting, disconnecting or troubleshooting any hose(s). Refer to Chapter 3 of the adhesive application unit s manual for hose installation location, instructions and an illustration specific to your ASU. Gemini hoses connect to the ASU with both an adhesive port connection on the filter outlet manifold and a 15-pin electrical connector. The opposite end of the hose connects to the applicator (head or handgun) with both an adhesive inlet connection and a 9-pin electrical connector. Refer to the Hose Installation Diagram on page 3 as a general guide. Observe the following cautions when connecting and routing adhesive hoses. CAUTION: When tightening hose swivel fittings, hold the hose and cuff to prevent the hose from rotating. CAUTION: If the hose is cold and contains adhesive, it may be damaged if bent. To avoid this, turn on power to the hoses and wait until the ASU s readout indicates that they are at operating temperature before routing them around surrounding machinery. CAUTION: Do not allow hose to be covered by machinery or by any type of solid conduit, pipe, tubing, etc. CAUTION: Maintain a minimum of 1/2 clearance between adjacent hoses.

WARNING: HIGH PRESSURE, HOT ADHESIVE When disconnecting a hose or hose cap, hot adhesive can escape from both the manifold and from the end of the hose under high pressure. Wear a face shield, gloves and protective clothing. Stand clear until all pressure is relieved. Before disconnecting a hose, turn the ASU s pump/motor OFF. Then activate the applicator to relieve adhesive pressure in the system. To Check Temperature Sensor Resistance When temperature sensor resistance is being verified, refer to the Resistance Table in Chapter 7 of the ASU s manual. The temperature sensor in Gemini Dynacontrol hoses is a 100 Ohm platinum RTD. The temperature coefficient is Ohms/ Ohm/ C. Refer to the ASU service manual for system wattage limitations. Hose Troubleshooting Tip Hose problems can be isolated by electrically connecting the hose to an alternate socket on the ASU. If the malfunction goes with the hose, the problem will usually be in the hose that was moved. If the malfunction does not move with the hose, the problem is probably in the ASU.

4 Page 4 ITW Dynatec c The Gemini Advantage The hoses of Dynatec s Gemini adhesive hose line are designed with built-in heater and sensor backups to aid the user in the event of a failure in these two components. Troubleshooting Heaters and RTD Sensors in Gemini Automatic Hoses With the automatic Gemini hose, there is no need for the operator to troubleshoot the hose. The hose will switch between good and bad heater and the good and bad sensor automatically. Note: both heaters and sensors will switch when one or the other becomes faulty. Troubleshooting Heaters and RTD Sensors in Gemini Manual Hoses Follow this procedure to determine if the failure of a hose is due to a faulty heater or RTD sensor before switching between the two heaters and sensors in the Gemini switch assembly. 1. Disconenct hose from ASU or applicator following the instructions outlined on the previous page. WARNING: HIGH PRESSURE, HOT ADHESIVE When disconnecting a hose or hose cap, hot adhesive can escape from both the manifold and from the end of the hose under high pressure. Wear a face shield, gloves and protective clothing. Stand clear until all pressure is relieved. 2. Make sure that incoming line power to the ASU and that the unit s Main Power Switch are turned OFF. DANGER HIGH VOLTAGE Disconnect and lock out input power to the application system before proceeding with these instructions. 3. Test resistance using the pins within the hose connection: a. To determine RTD sensor failure: The resistance value (Ohms) of your temperature sensor depends on the temperature of the sensor at the time it is being tested. At 25 C(77 F), the resistance of a DCL PT 100 (Platinum) sensor should be 110 Ohms at 25 C(77 F). With an ohmmeter, contact pins 9 and 10 and measure resistance. A tolerance range of ± 5% is allowed. b. To determine heater failure: With an ohmmeter, contact pins 11 and 12 and measure resistance. Heater circuit resistance is listed on the red hose warranty tag attached to the adhesive supply unit end of the power cord. A tolerance range of ± 10% is allowed.

The switch box of the Gemini Automatic hose should never be opened. Opening it will void your Dynatec hose warranty. 1. When either a heater or a RTD sensor becomes faulty on a Gemini Automatic hose, the hose will automatically switch to the good heater and sensor. No action is required by the operator. 2. When the hose makes the switch to fresh components, the light will turn ON in the hoses switch box. The light will stay ON or blink for the life of the hose. Using the Gemini Manual Hose s Switch Assembly Once it has been determined that either the heater or the RTD sensor is faulty in a Gemini Manual hose, use the appropriate switch within the Gemini switch enclosure to toggle between the hose s two heaters or sensors. Procedure: 1. Loosen the four screws in the corners of the Gemini switch box. Remove switch box cover. 2. Locate the switch of the faulty component (heater or sensor). 3. Toggle the switch from circuit #1 position to circuit #2 position. See illustration below, right for closeup of circuit positions. Note: Switches are always in position #1 when hose is shipped from ITW Dynatec s factory. Position #2 is the backup circuit. 4. Re-intall switch box cover. cover switchplate Record switch actuation date here 5. On the switch box cover label, record the date of circuit #2 actuation in the space provided for H2 or S2. heater switch sensor switch Gemini Manual Hose Circuit Positions Gemini Manual Hose Switch Assembly in diagram above, both heater and sensor are in Circuit #1 (left) position. in diagram above, both heater and sensor are in Circuit #2 (backup) position.
