-After Checking the condition
of connection in connector
attached to mold and change
polarity of T/C
4
error code

Disconnected
-Check resistance of heater
with tester.
If it is blown out, replace
heater

heater or capacity
of heater is higher
than upper limit of
current
- Check short or open of

No Phenomenon Probable cause Check Point
10
Temperature
drops
continuously
- FS1 or FS2 fuse
open
- Heater open
- the part of wire in
heater is opened
- Sensor (T/C) open
- Change fuse (250V 20A)
- Check resistance of heater
with tester
- Check heater open
11
Severe Tem-
perature (De-
viation between
SetTemp&Sensing
Temp.)
- Sensor Contact is
unstable
- Sensor type is dif-
ferent in each other - Check contact state of
sensor
- Check sensor type
- Try to re-tuning
12
Controller Tem-
perature doesn’t
rises,
But heater in ac-
tua mold is over
heated
T/C wire is pressed
by mold or it’s coat
is peeled, so as to
contact mold or line
Check T/C wire and replace it
13
Setting tempera-
ture of controller
equals with pre-
sent temperature,
but the heater
in actual mold
is overheated or
cold.
T/C (sensor) type
between mold and
controller is differ-
ent. ex) CA(K)→IC(J)
IC(J)→CA(K))
Make T/C (sensor) type of
mold equal with that of
controller.
