Troubleshooting Tips and Part # Information

There is an oil seal between the motor and the gearbox.  While seals and journals are of high quality, the seal has a finite life.

Motors positioned with the gearbox above the motor (Style C&D Sealers) will eventually see some leakage of gearbox lubricant back into the motor as the seal wears out.  To prevent this occurrence, even in the long term, the gearboxes may be filled with grease rather than the standard gear lube when they are to be positioned vertically, gearbox above motor.  The grease is too heavy to migrate around a worn seal or journal.

Someone has inadvertently pressed the STAT key or the program has been lost.

Insure that air pressure is attached to the machine and heat settings are correct and in-range then press the MSG button.  If this does not restore the screen to show normal operating details, the program may have been lost.

You can also check the I/O LEDs on the PLC itself.  You should see some LEDs lit on the output side of the PLC.  If not, the program is very likely lost or corrupt.

Program loss is common if the machine has been in storage and not under power for one year or more.

Contact us to schedule service to get a new copy of the program loaded on your PLC.

Thermocouple wires are loose or broken.

Check thermocouple wires at temperature controller.  Make sure connections are tight.  If they are and "E-7" error still appears, detach wires from temperature controller and check for continuity across thermocouple wires.

Solution: If no continuity, replace thermocouple (i.e. Heater Harness Assembly)

Possible causes include worn motor brushes, failing DC Speed Controller, motor nearing end of life, loose timing pulley or proximity sensor.

Check to make sure the timing pulley is secured to its shaft and that proximity sensor is sensing each tooth on the pulley as it rotates.  Check motor brushes and replace if worn.  With a multi-meter, measure DC voltage output from the DC Motor Controller - At a single speed setting, the voltage output should be constant (+/- approx. 2-3 volts is typical and OK).  Voltage output which varies more than 2-3 VDC suggests impending failure of the DC Motor Speed Control Board.

Solution: Replace worn or failing components.
