MACHINE TECHNOLOGY & COMPONENTS ENERGY SMART TECHNOLOGY The Energy Smart Wrapper is an innovative system that incorporates an Instant On seal plate with the ability to go from ambient to sealing temperature in a matter of seconds. The high speed seal plate, in combination with a photoeye actuation, allows the operator to seal a product on demand and to save energy when the wrapper is not in use. As a part of our quality procedures, the seal plate has been tested. Note: You may see a wavy or wrinkling affect on the surface of the stainless steel plate under the replaceable Non-stick cover. This waviness is caused by the differential thermal expansion of the materials that are used to construct the layered seal plate; wrinkling will be observed as the wrapper is used daily and the seal plate settles in. HOT ROD HEAT UP With the film properly mounted and threaded, the wrapper is ready to be powered up. After plugging the power cord into an electrical outlet, toggle the power switch (1) located on the side of the electrical box to the ON position. The hot rod (2) will require about a 5-10 minute warm up period before it reaches a cutting temperature of above 275 F. CAUTION: As long as the wrapper is powered on, the rod will be hot and skin contact should be avoided. PHOTOEYE ACTUATED HEATER The seal plate of the wrapper is actuated by a photoeye that is engaged when a package is placed on the plate (3). This feature ensures that the seal plate will consume energy only when there is a demand by the operator. DO NOT USE THE SEAL PLATE AS A CUTTING SURFACE, AS THIS WILL DAMAGE THE SEAL PLATE AND NON- STICK COVER PLATE. SEAL PLATE DAMAGE VOIDS THE WARRANTY. ELECTRICAL RATING 2 The Model SM20ES is rated 115 volts, 132 watts. 3 1 *scale pictured is not included 3
MACHINE TECHNOLOGY & COMPONENTS STAINLESS STEEL BRIDGE The wrapper comes with a stainless steel bridge (1) that is used to position the scale for weighing and wrapping a package. The stainless steel bridge is not recommended as a cutting surface and should not be used as one. TWO ROLL CAPACITY The wrapper has the ability to house two 20 rolls of film at a time (2). The rolls should be mounted and threaded as shown on pages 5-6. For cradle machines, see threading diagram on the right side of the unit. OPERATOR INDICATOR LIGHT Since the sealing plate is only activated when a load is applied, a red neon light has been included to provide the operator a visual indicator that the heater is active (3). When the light is on, the seal plate is powered and its surface will become hot instantly. *scale pictured is not included *Alternatively, on some models, the light will turn yellow while the plate is heating and will then turn red when the plate reaches sealing temperature. GFCI To maintain circuit protection and integrity, a GFCI (4) is installed in the accessory outlet located midway up on the back left side of the frame. The GFCI may need to be reset if wrapper gets wet or other ground faults arise. Do not reset the GFCI, if visible seal plate damage is present. THERMISTOR TEMPERATURE CONTROL Due to the rapid response of the seal plate and residual heat that can remain from previous cycles, a thermistor is incorporated as a temperature control device. The seal cycle will be shorter than 3 seconds when residual heat is present in seal plate; typically as short as one half second. The thermistor is located inside the seal plate assembly and it regulates the temperature of the seal plate to ensure that it consistently reaches sealing temperature. NOTE: The thermistor is the governing control to supply heat to the seal plate. Therefore, if residual heat is present in the seal plate, the heat controller automatically adjusts the heat cycle. 4
PRELIMINARY SETUP - AXLE MOUNT MOUNTING FILM ON AXLE 1. Loosen four wing nuts (A) 2. Swing out upper bearing blocks (B) on both sides 3. Lift out axle assembly (C) and unscrew movable end cap (D), position fixed end cap (E) for correct film width then secure with pin (F) and o-ring (G) 4. Position the cardboard core of the film roll against the taper of the fixed end cap. Make sure the film is threaded from the bottom of the roll and under film roller (H) (see threading diagram below) 5. Replace adjustable end cap (D) and screw on tightly 6. Replace the axle assembly (C) and film roll onto the lower bearing blocks (J), swing upper bearing blocks (B) back into place and tighten and adjust wing nuts (A) for desired film tension A B J ITEM PART # 1 6340-060 2 6135-033 H E G F C DESCRIPTION D Bearing Block Set, Includes: (1) LH Upper Block (1) RH Upper Block (2) Bottom Block (4) Stainless Steel Wing Nut (4) Rubber Luster Cap (4) Stainless Steel Hex Screw 3 Core Adapter Set Includes: (1) 3 Adjustable Core (1) 3 Fixed Core (1) Pin Core Adapter (1) O Ring J B 3 3005-047 Film Core Axle, 24 L FILM THREADING - AXLE MOUNT Mount the film with axles onto the bearing blocks so the film comes off the bottom of the roll Pull film from the bottom of the roll, under the film guide roller (1), and up through the film selector rollers, starting with the nearest slot to the hot plate first (2) Drape unused film in the front of the film selector roller (3) 5
PRELIMINARY SETUP - CRADLE MOUNT FILM THREADING - CRADLE MOUNT Film threading is very important on cradle style wrappers to achieve proper film tensioning. Facing the tension knob side of the machine, the film should come off the roll counter-clockwise and go in-between the two rollers it sits on. Pull film under the film guide roller (1), and up through the film selector rollers. Route the upper film roll first. The black tension knob (3) can be adjusted for proper tension on the film by loosening (rotate counter clockwise) or tightening (rotate clockwise) the knob. See threading diagram to the right and also located on the film guide bracket cover. ADJUSTING FOR DIFFERENT WIDTH FILMS Squeeze the tensioning devices (4) and slide the white film guides (5) (one on each side of film roll) and secure it near the film roll on both sides. This will help maintain the roll in the center of the machine. 6
RECOMMENDED MAINTENANCE * MAKE SURE TO TURN OFF THE UNIT, PULL THE PLUG AND LET THE MACHINE COOL DOWN BEFORE CLEANING * NON-STICK COVER & SEAL PLATE Due to the advancement of this new technology, it is extremely important to maintain the Non-stick cover in good condition. It is recommended to replace the Non-stick cover at least once every three months to protect the seal plate and maintain a sanitary surface. The seal plate should not be used as a cutting surface; any punctures will render the seal plate ineffective and will void the warranty. The seal plate has been designed to provide long life performance when it is properly maintained. The Non-stick cover is used to create a sanitary, stick free surface to seal film with the seal plate. Non-stick covers are porous, meaning liquids or moisture can permeate the cover, get to the surface of the seal plate, and burn off on the hot plate. It s recommended that the Non-stick cover be replace every three (3) months or as needed depending on the level of daily wear and tear. The Non-stick cover should be changed if the surface is soiled, or holes, punctures, excessive wear, or damage are present. The seal plate can be cleaned, as needed, with a mild spray degreaser. This should be applied to a soft cloth or paper towel and then wiped on the plate while cold. DO NOT WASH DOWN SEAL PLATE OR SPRAY ANY LIQUIDS DIRECTLY ONTO THE PLATE. CUT OFF ROD Make sure that the unit is turned off and the cut off rod is cold to the touch. The film cut off rod can be cleaned, as needed. Cover the unit surfaces with paper towels to protect them from over spray and debris. Spray and coat the cut-off rod generously with an FDA approved Degreaser product. After soaking for a few minutes, lightly scrub the surface of the Cut-off rod with a Scour Pad (Scotch-Brite type pad). Wipe the surface clean of debris and residue with clean paper towels or cloths. CLEANING THE UNIT The SM20ES can be completely wiped down using mild cleaning detergent and a soft cloth or paper towels. DO NOT HOSE DOWN OR SUBMERSE THE UNIT. 7
TROUBLESHOOTING Symptom No power to the unit. Possible Solution Verify the unit is plugged into a 15 Amp circuit and the Power Switch is set to the ON position. First, is the GFCI circuit breaker tripped? 1) Remove Non-Stick Cover and inspect the Seal Plate for the following defects: Punctures or cuts. Burn marks. Extreme discoloration (blue/black or gold). If these defects are present, replace seal plate. 2) If seal plate is in good condition, reset GFCI. If GFCI cannot be reset, replace. 3) Reset new GFCI. Red Power Light at right front of unit SHOULD glow. 4) If GFCI trips, seal plate may have moisture inside. Allow 1-2 days to dry out and then retry. Figure 1 SM20ES Electrical Box Pictured 8
TROUBLESHOOTING Symptom Unit has power but the Seal Plate does not work Possible Solution Verify power. Does the Cycle Light turn ON when the unit is cycled? 1) If neither the Light nor Seal Plate work, verify that the 20 Amp Circuit Breaker is not tripped. 2) If the Circuit Breaker is tripped, verify there are no shorts to ground in the unit by checking wiring and connections (see Figure 1). Reset Circuit Breaker. 3) Replace Circuit Breaker if it cannot be reset. Next, verify the Photo eye is working properly. 1) With the Power ON, there should be a Green Light illuminated on the back of the Photo Eye. When the Photoeye is triggered a separate Yellow Light will illuminate. 2) If Green Light is ON and Yellow Light DOES NOT illuminate when the Photo Eye is blocked, replace the Photo Eye. 3) If Green Light is NOT illuminated when unit power is ON, check Control Board to determine if Photo Eye or Control Board is faulty. Next, verify the control board is working properly. 1) Check the voltage on Pin 1 of the Control Board using a multimeter. If not 120vac, a wiring issue exists. Find and repair. 2) Check voltage on Pin 4 & 5, Brown & Blue Wires. This voltage should be 10 to 30vdc If NO voltage present, replace Control Board. If voltage present, replace Photo Eye. Next, verify seal plate. If the plate does not heat at all or is only slightly warm to the touch, replace the Seal Plate. Film Cut-off Rod does not work at all. Film cuts too slowly Verify the unit is plugged into a 15 Amp circuit and the Power Switch is set to the ON position. Verify that the 1 Amp circuit breaker is not tripped. If the circuit breaker is tripped, then reset, verify there are no shorts to ground in the unit by checking wiring and connections. Clean Cut-off Rod surface and verify it is not bent. See Cut-Off Rod Maintenance. Replace Square Boardless Cut-off Rod 9
