1. Install a section of belting large enough to cover the platen area.
2. Install the temperature meter sensors above and below the belting, 8 inches (200 mm) from the electrical
connector. That is where the platen temperature sensor is located. Cut a groove in the belting to prevent
damage to both sensors and platens.
3. Assemble the vulcanizer and pressurize to 5 psi (0.3 kg/cm2) maximum.
9.3.1. Auto Tune
Each temperature controller has an AUTO TUNE (AT) function that calibrates the controller with the heating
element and the temperature sensor. The controller has been calibrated at the factory and will not require
calibration unless the controller, the heating element or the temperature sensor are changed. Auto Tune the
controller as follows:
1. Connect the power supply and switch the platens to
1A
.
2. Turn the Keyed RESET Switch.
3. Press the level key momentarily until.Adj appears in the PV display.
4. Press the mode key once, until the At appears in the PV display.
5. Using the ∧ key, select At-2. The AT diode will flash until auto tuning is complete. After set point has
been reached, it may take approximately 20 minutes for the AT diode to stop flashing. It is necessary to
wait for the AT diode to stop flashing before proceeding to return to the temperature display.
6. Press and hold the level key until the CN-t appears in the PV display.
7. Press and hold the level key until the temperature display appears.
9.3.2. Input Shift
If the external temperature meter reading and the temperature controller value are not the same, the controller
should be adjusted. Subtract the controller reading from the external temperature meter reading and record this
difference. Adjust the controller as follows:
1. From the Operation level display press the Level key for one second until LAdJ appears in the PV display.
2. Press the Mode key until INS appears.
3. If the temperature difference is positive, use the ∧ key to select the difference.
4. If the temperature difference is negative, use the ∨ key to select the difference.
5. Press the Level key and hold until IN-t appears, press and hold the level key until the Operation level
display appears.
6. Insert the stem thermometer and adjust the thermometer dial until the reading is the same as the test meter.
See directions on stem thermometer.
