2 Rapid temperature change
This error occurs in the tuning procedure and highlights the operation
started with the heating element hot. Wait for it to cool and repeat the
operation.
3 Insufficient voltage reading;
this error occurs in the tuning procedure and highlights an error in
transformer connection or in its dimensioning. During the first tuning
operation after installation, it may also indicate improper connections.
4 Insufficient current reading;
this error highlights breakage of a heating element when using elements in
parallel, if it occurs during the tuning procedure it highlights a
dimensioning error of the pulse transformer or in jumper configuration on
the temperature controller. During the first tuning operation after
installation, it may also indicate improper connections.
5 Too high voltage reading;
this error highlights voltage is too high in the equipment feedback and
requires a tuning procedure. During the tuning procedure, an error
highlights in the transformer connection. During the first tuning operation
after installation, it may also indicate improper connections.
6 Too high current reading;
this error highlights the short circuit of one of the heating elements when
using elements in series, if it occurs during the tuning procedure it
highlights a dimensioning error of the pulse transformer or in jumper
configuration on the temperature controller. During the first tuning
operation after installation, it may also indicate improper connections.
7 Voltage not reaching the heating element
Possible causes:
- Power adjustment element (TRIAC) faulty.
- Connections between the temperature controller and the heating element
interrupted.
- pulse transformer faulty.
8 Current not passing through the heating element
Possible causes:
- heating element damaged.
- loose heating element fastening.
9 Voltage reaching the heating element not read.
Possible causes:
- the feedback cable to the temperature controller is interrupted.
- loose connections on the temperature controller terminals.
- distortion on the power supply line too high.
