RC3-LOG & RC3P-LOG INSTRUCTION MANUAL SEPT 2018
Note:
The temperature controller is a snap in module that can be replaced with a + blade screwdriver, and is a
recommended spare part. If you have ordered a spare controller, it will be factory set to an average value that
will control your platen reasonably well.
Auto Tune
should still be done as follows.
An external means of checking the platen temperature is required. A portable temperature test meter with at
least two leads is best to conduct the calibration tests. These may be purchased from
Shaw-Almex.
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).
6.3.1. Auto Tune
The 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 is changed. Refer to the special
autotuning instructions for autotuning your RC3(P)-log controller.

TROUBLESHOOTING
This controller has many capabilities other than those used for the Almex Temperature control panel. Adjust
only those settings described above. Other adjustments may result in the control box being inoperable. For
detailed instruction of the ALMEX NANODAC controller, refer to the ALMEX NANODAC instruction
manual supplied with this temperature controller.
7.1.
No Display on Temperature Controller
FAULT
CORRECTION
1.
Power supply is faulty.
1.
Check the supply cables and power supply connection.
2.
Control circuit fuse has
opened.
2.
Disconnect power supply, open the control cabinet,
correct the fault in the control circuit and replace the fuse.
7.2.
Error Display on Temperature Controller
FAULT
CORRECTION
1.
Loose connection in cable or
platen connector.
1.
Remove electrical connector insert from housing and
tighten all connections.
2.
RTD temperature sensor is
faulty.
2.
Measure the resistance between pins 4-5 and 4-6 on the
platen electrical connector. Depending on the platen
temperature, the resistance should be between 100-170
Ohms. Replace sensor as described in the vulcanizer
manual. The wires should be protected from moisture by
using a small amount of silicone in the back of the insert
terminal to seal the connection.
