10. TROUBLESHOOTING
The 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 panel being inoperable. For
detailed instruction of the E5CN-H controller, refer to the OMRON instruction manual supplied with this
temperature controller. Unqualified personnel must not open or work on these units. Any unauthorized work or
adjustments immediately VOIDS warranty.
10.1. No Display on Temperature Controller
FAULT CORRECTION
1.
Power supply is faulty. No phase
lights are on.
2.
Phase lights are on, no power to
system.
1.
Check all cables and power supply connection, and reset the
main feed power breaker.
2.
Check the main breaker on the control box. The temperature
controllers (or pair of controllers) will turn off when the platen
and/or cable is disconnected. Check the indicator lights for
diagnoses. Check the earth fault indication light.
3.
Control circuit fuse has opened.
3.
Disconnect power supply, open the control cabinet, replace 10
or 15FU fuse in the circuit and reset the breaker.
10.2. Error Display on Temperature Controller or Indication Lights
FAULT
CORRECTION
1.
SERR Is indicated on the
temperature controller.
2.
Red push button indicator light on
face.
3.
Pilot indication lights will not
show GREEN and allow operation
of the press.
4.
Loose connection in cable or
platen connector.
1.
This usually means an RTD probe is an incorrect type, has failed
or the signal is not getting to the temperature controller.
2.
This shows earth fault condition has occurred. Have a qualified
person repair the problem. This will also light when the test
button is pushed.
3.
Check the platen and / or pump earth to pilot pins for a 300 to
345 ohm resistance. If close to 0 ohms you have a short between
the pilot and ground and needs IMMEDIATE repair before use.
If the resistance is above 345 and a yellow light is being
indicated your earth is faulty and needs IMMEDIATE repair
before use. If you have 300 to 345 ohms and the green
indication will not come on the pilot system has failed and needs
IMMEDIATE repair before use. Contact Shaw Almex for repair
information.
4.
Remove electrical connector insert from housing and tighten all
connections.
5.
RTD temperature sensor is faulty.
5.
Measure the resistance between pins 4-5 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.
10.3. Platens Not Heating
FAULT CORRECTIONS
1.
Power supply faulty.
1.
Check that all three phases are powered.
2.
Platen switch OFF.
2.
Turn platen switch ON.
3.
Temperature set improperly.
3.
Ensure that controller set point is correct.
4.
No continuity between power
supply and platen.
4.
Check thermal overloads on the output relays.
5.
Loose connection in control panel.
5.
Disconnect power supply, open the control cabinet and check for
loose wire connections.
6.
Faulty temperature controller.
6.
Refer to Omron instruction manual.
