Frequently Asked Eastey L-Sealer Questions

 

Note: Checking items in this frequently-asked-questions list should be done only by technicians with training and previous experience with the L-sealer. Be aware of electrical hazards when checking voltages and electrical connections. Disconnect electrical power before making any repairs or adjustments when applicable and follow your company’s lockout/tagout rules and procedures for the L-sealer and all equipment connected to it. Be very careful when servicing or adjusting this equipment. If in doubt, stop and obtain qualified help before proceeding.

 

CAUTION!      When replacing conveyor motor, the switch may need to be turned on to apply power to the motor for testing.

 

  1. Why is the film sticking to the blades and inserts?
    • Check the coating on the PTFE blade and insert.

    • Check input and output of the magnet transformer.
    • Check input and output of bridge rectifier.
    • Swap timer with conveyor to see if the issue follows timer.

 

  1. Why is my seal head not returning to fully open position?
    • Cylinder is faulty.
    • Grease the pillow blocks.
    • Set screws have slipped on the rear shaft.

 

  1. Why is my conveyor not running after a seal?
    • Swap well and conveyor timer, if problem follows the timer, replace timer

 

  1. Why is my film tearing as it goes through the film rack?
    • Check to make sure the pin is spinning freely.

 

  1. Why is it hard to pull the film with a power film unwind?
    • Make sure dancer bar switch is activating when lifted.
    • Check fuses on PFU.
    • Clean rubber drive roller of film residue.

 

  1. Why are my magnets humming?
    • The seal head magnet disks are not fully engaging the lower electromagnets.
      • Lift the lower magnet up slightly.

 

  1. Why am I getting a weak seal on the front or side?
    • Sponge rubber has deteriorated, replace sponge.
    • Check heat, pressure, and dwell.

 

  1. Why are my magnets not releasing?
    • Swap timers to verify the problem does not follow the timer.
    • Make sure the timer is in mode A.
    • Make sure your timer is set for seconds 1-5.

 

  1. Why won’t my machine turn On?
    • Check incoming power.
    • Check main fuses.

 

  1. Why can’t I turn the crank handle to raise or lower the conveyor?
    • The threads are seized, need to replace crank handle and barrel nut.

 

  1. Why does my temp controller read “LLLL”?
    • The thermocouple is connected backwards. The Red is the negative and the white is the positive.

 

  1. Why is the seal head hard to pull down?
    • Too much stroke has been put on the return cylinders.
    • Grease the bearings.

Frequently Asked Eastey Heat Tunnel Questions

 

Note: Checking items in this frequently-asked-questions list should be done only by technicians with training and previous experience with the shrink tunnel. Be aware of electrical hazards when checking voltages and electrical connections. Disconnect electrical power before making any repairs or adjustments when applicable and follow your company’s lockout/tagout rules and procedures for the shrink tunnel and all equipment connected to it. Be very careful when servicing or adjusting this equipment. If in doubt, stop and obtain qualified help before proceeding.

 

CAUTION!      When replacing motors, if the tunnel chamber is below 160 degrees, the heater bank switch may need to be turned on to apply power to motors for testing.

 

  1. My motor on my Eastey heat tunnel is running full speed. Do you have an idea of why this could be?
    • The conveyor drive motor has shorted out. The motor requires replacement.
    • Recommend replacing the motor, resistor, and fuses on the DC board,

 

  1. The Red light on my DC board is on as well as the green light. Do you know why this is?
    • The resistor is blown, and possibly the motor is bad.
    • Recommend replacing the motor and resistor.

 

  1. My Eastey tunnel gets up to temp and then the temperature drops. The temperature then continues to drop slowly. Do you know what could be the cause of this?
    • Make sure you are not going over the maximum temperature of the tunnel (450 degrees F). If the machine goes above this temperature, the over-temp relay will not allow the machine to heat up.
    • Check the heater bank toggle switch.
    • Check the heater contactor.
    • Check the output of the temperature controller.

 

  1. I have my tunnel set at 350 degrees, but it only gets up to 270 degrees. Do you know what could cause this?
    • One or more coils are burnt out on the heater bank.
    • Check the heater bank and replace or repair it as necessary.

 

  1. When I turn the heat tunnel to cool down, everything turns off. Do you know what could cause this?
    • Temperature controller parameters are not set correctly.
    • Pre-2019: the delay cool down sensor is faulty.

 

  1. My Eastey heat tunnel temperature controller is flashing JiCH/In-t when I start the machine. Do you know what this means? (Pre January 12, 2023 controller.)
    • If the controller continually flashes, the temperature controller has failed.
    • Replacing the temperature controller is recommended.

 

  1. When I turn my Eastey heat tunnel on, nothing happens. I get lights on the temperature controller, but the conveyor, blower, and heater do not turn on. What should I look for?
    • Check all fuses. If the fuses are good, the toggle switch is faulty.
    • Replace the toggle switch.

 

  1. When I turn on the Eastey heat tunnel, everything works except the conveyor drive motor. What should I look for?
    • Check the indicator lights on the DC board.
      • If you don’t have any lights (with heater bank toggle switch turned on), check the AC side fuse and voltage input into the board.
      • If you have a green light and a red light, refer to Question 2, above.
      • If you have a green light on the DC side, the fuse is likely blown. Replace the blown fuse.

 

  1. My temperature controller reads open. Do you know what this means?
    • The thermocouple is not communicating with the temperature controller.
    • Replacing the thermocouple is recommended.

 

  1. I turned up my heat tunnel to 450 degrees. Now the temperature is dropping. Do you know what I should do next?
    • The tunnel went into over-temp.
    • Turn down the temperature to 430 degrees or lower and cycle power.

 

  1. Customer says they blow the medium 10 Amp fuse once they start the machine up. I replaced them once and they blew right away. Do you know what I should check?
    • This is usually the conveyor motor.
    • Try disconnecting the motor and replacing the fuse. If the machine does not blow the fuse, replace the conveyor drive motor.
