7. TROUBLESHOOTING
This controller has many capabilities other than those used for the Almex Temperature Control. Adjust only
those settings described above. Other adjustments may result in the control panel being inoperable. For detailed
instruction of the E5GN controller, refer to the OMRON manual supplied with this temperature control panel.
7.1.
No Display on Temperature Controller
FAULT CORRECTION
1.
Power supply is faulty.
1.
Check the supply cables and power supply connection.
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 probe as described in the vulcanizer
manual. The leads should be protected from moisture by
using a small amount of silicone in the back of the insert
terminal to seal the connection.
7.3.
Vulcanizer Not Heating
FAULT CORRECTION
1.
Platen switch OFF.
1.
Turn platen switch to
1A
or
1M
.
2.
Temperature set improperly.
2.
Ensure that controller set point is correct.
3.
No continuity between power
supply and platen.
3.
Check power supply fuses or breakers and cable
connections.
4.
Loose connection in control
panel.
4.
Disconnect power supply, remove control panel cover
and check for loose wire connections.
5.
Faulty temperature controller.
5.
Refer to OMRON instruction manual.
6.
Faulty relay.
6.
Disconnect power supply, and remove control panel
cover. Very carefully connect power supply and with
temperature controller OUT light on, check for power
between relay terminals 2-6 and 4-8. If full line voltage is
not measured, relay must be replaced.
7.
Loose connection in cable or
platen connector.
7.
Remove electrical connector insert from housing and
repair any loose connections.
8.
Faulty RTD temperature
sensor.
8.
Measure the resistance between pins 4-5 and 4-6 on the
platen electrical receptacle. Depending on the platen
temperature, the resistance should be between 100-170
Ohms.
9.
Faulty heating element.
9.
Measure the resistance between pins 1-3 on the platen
electrical receptacle. Compare the reading with the value
in your Record of Purchase, Element Resistance, Coils
Connected. If the values are not close and the wires and
connections are good, the element must be replaced.
