7.
Faulty relay.
7.
Disconnect power supply, and open control cabinet. Very
carefully connect power supply and switch the platen on. The
temperature controller OUT 1 light should be ON. Check for
line voltage between line side (L1, L2 and L3) and ground on
the contactor. If there is voltage, check voltage between load
side (T1, T2 and T3) on the contactor and ground. If line voltage
is not measured, be sure the contactor is being called down. If it
is the contactor is faulty and must be replaced.
8.
Loose connection in cable or
platen connector (breaker will trip)
8.
Remove electrical connector insert from housing and tighten all
connections.
9.
Faulty RTD temperature sensor.
9.
Measure the resistance between pins 4-5 on the platen electrical
receptacle. Depending on the platen temperature, the resistance
should be between 100-170 Ohms.
10.
Faulty heating element.
10.
Measure the resistance between pins 1-2, 2-3 and 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. 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.
10.4. Vulcanizer Over Heating
FAULT CORRECTION
1. Temperature set improperly. 1. Ensure that controller set point is correct.
2. Faulty temperature controller. 2. Refer to Omron instruction manual.
3. Faulty relay. 3. Disconnect power supply, and open control cabinet. Using an
Ohmmeter, check for continuity between terminals L and T on
the suspect relay. If there is continuity, relay must be replaced.
4. Faulty RTD temperature sensor. 4. Measure the resistance between pins 4-5 on the platen electrical
receptacle. Depending on the platen temperature, the resistance
should be between 100-170 Ohms.
10.5. Controller will not maintain Set Point Temperature
FAULT CORRECTION
1. Controller not calibrated properly. 1. Follow calibration procedure.
2. Faulty temperature controller. 2. Refer to Omron instruction manual. Replace temperature
controller or call for assistance.
10.6. Yellow or Red on Platen Indicator Light
FAULT CORRECTION
1. Plugs not in tightly enough and
a yellow light is showing.
2. The Pilot end resistor has
failed.
1. Be sure plugs are push in and clamped securely.
2. Check from pin 4 to earth. You should have a reading of
300 ohms. If not replace resistor using the Pilot kit
available form Shaw Almex.
3. End pilot resistor not present in
the platen and a yellow light is
showing.
4. A red light is indicated on the
Platen Indicator due to weak
earth wires.
5. The pilot Checking Circuit has
failed.
3. Purchase a GF Pilot kit to install in the platen to correct
the situation or use the correct platens.
4. Repair the ground/earth line or the pilot line so the correct
resistance is present. With the pilot kit installed the pilot
pin to ground must read 300 +- 10% ohms.
5. The Red light is preprogramed to be on from an input of 0
ohms to 250 ohms from pin 4 to ground. The Yellow
light is preprogramed to be on from an input of 340+
ohms from pin 4 to ground. For instructions or
replacement parts contact Shaw Almex.
