Faults Solutions
No air
Check for air in the supply line.
No current
Check that the main switch is in "ON" position.
Fault in temperature
rise (Probable presence
of liquid in the cooling
circuit)
- Turn the switch on the PMR-06 regulating unit to “ON”.
- Push the “START” button to start the joining cycle.
- As soon as you have pushed the “START” button press the “STOP JOINING
CYCLE” button. This starts the cooling procedure that finally expels the water
from the cooling circuit.
- Refer to the operating instructions of regulating unit PMR-06 for further
details.
ATTENTION -
When expelling water with compressed air, make sure no
water comes into contact with any of the electrical equipment.
Temperature deviation
of a heating plate of
more than 2 °C with
respect to the nominal
value
Exchange the two connectors in the rear part of the regulating unit and check
whether the regulator always indicates the same anomalous value.
In this case the fault can clearly be traced to the regulator in question.
If the defect should pass to the other regulator, the fault can be attributed to
the corresponding heating plate or the thermocouple signal wire.
In any case take a temperature check of the heating plates if there is a
discrepancy (see
ROUTINE AND SCHEDULED MAINTENANCE
In case of faults of this or any other kind, the manufacturer should be informed.
The heating plates and the defective regulators can be repaired or replaced by
the manufacturer.
Electrical faults
If a fault develops in the control/regulatory electronic unit, in the first place the
automatic switches in the regulating unit should be checked.
The automatic switches control output and are accessible from the outside.
Supplementary automatic switches to control command current are located
inside the regulating unit.
