7.3.
Platens Not Heating
1.
Platen switch OFF.
1.
Turn platen switch ON.
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 (inside panel) and cable
connections.
4.
Loose connection in control
panel.
4.
Disconnect power supply, open the control cabinet and
check for loose wire connections.
5.
Faulty temperature controller.
5.
Refer to ALMEX NANODAC instruction manual.
6.
Faulty relay.
6.
Disconnect power supply, and open control cabinet. Very
carefully connect power supply and switch the platens on.
The temperature controller should be showing an output
to this channel.. To verify that power is getting to each
relay check for voltage between terminal "A1" and
terminal “A2” of the Power relays for the top and bottom.
If a particular relay is receiving incoming power and is
receiving a signal from the controller, but is not sending
outgoing power then that relay is faulty and must be
replaced.
7.
Loose connection in cable or
platen connector.
7.
Remove electrical connector insert from housing and
tighten all connections. The wires should be protected
from moisture by using a small amount of silicone.
8.
Faulty RTD temperature
sensor.
8.
Measure the resistance between pins 4-5 and 4-6 on the
platen receptacle. Depending on the platen temperature,
the resistance should be between 100-170 Ohms.
9.
Faulty heating element.
9.
Measure the resistance between pins 1-2, 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 wires should be protected from moisture by using a
small amount of silicone in the back of the insert terminal
to seal the connection.
7.4.
Vulcanizer Over Heating
FAULT
CORRECTION
1.
Temperature set improperly.
1.
Ensure that controller set point is correct.
