Delta Laminator
3.3 TROUBLESHOOTING – PROBLEMS ARE NOT INDICATED ON THE
CONTROL PANEL
3.3.1 Error – heating on the laminating roll is not active – end sides or middle
Possible indications of statuses:
•
Bad laminated sheets quality
•
A Part of the laminating roll is colder than the others
•
The difference between the sections on the laminating roll was established by the contact
thermometer
Status correction:
•
Check fuses FU1 (heating on the end sides) and FU2 (heating in the middle), if broken, replace
them.
•
Check if no error is reported when rotary switch HEATERS is turned to position START and
contactor KM7 is activated. If not, the error is possibly caused by disconnection of conductors
1001, 215. See DA-41-100n, sheet 10.
•
Check the correct function of power solid state relays A1 (heating on the end sides), A2 (heating
in the middle). If defective, replace them.
•
The error is possibly caused by disconnection of conductors 503 - N, 506 - N or it is probably in
the connector connection of these conductors. See DA-41-400n, sheet 4. Repair.
3.3.2 Error – the snap roll is not turning while the machine is running and the SNAP
MOTOR rotary switch is in the START position
Possible indications of statuses:
The snap roll is not turning while the machine is running and the "SNAP MOTOR" rotary switch is in the
"START" position.
Status correction:
•
Check circuit breaker FA2 if it is in position I. If not, set it to position I.
•
The error is possibly caused by disconnection of conductors 312 - N, 313 – N, 314, 315, 316.
See DA-41-100n, sheet 3. Repair.
•
The error may be caused by disconnection of conductor 909, which control frequency inverter
U2. Repair. See DA-41-100n, sheet 9.
•
Frequency inverter U2 failed. Reset the error by the control unit or by switching the machine off
and on. More detail about the frequency inverter - see the Mitsubishi manual.
