Type of Error
Description
Product to Service/
Service Due
The recommended next service date for the system is
overdue. The service due message has to be acknowledged
by pressing the START/SET key. Only the manufacturer or a
service point can reset the maintenance term.
Power Supply Failure at
Last Welding
The last welding is incomplete. The welding system was
disconnected from the power supply voltage while it was
in progress. To go on using the product, this error has to
be acknowledged by pressing the STOP/RESET key.
Ambient Temperature
High
Outside temperature not within the range from – 20°C
to + 60°C.
Ambient Temperature
Low
Outside temperature not within the range from – 20°C
to + 60°C.
Overheated
The temperature of the control and hydraulic unit is too
hot. Let the welding system cool down for about 1 hour.
Pressure Sens. Defective The sensor indicated on the display (hydraulic pressure,
heating element temperature, ambient temperature) is
defective; where possible, check the connections/plug;
have the machine inspected by a qualified service shop if
needed.
Heating Sens. Defective
Temperature Sensor
Defective
Printer not Ready
(only label tag printer)
The optional printer is not ready (possible reasons also: no
communication or faulty cable).
Download Cancelled
During data transfer or printing, an error condition
occurred which could not be cleared.
Memory Full
The system memory is full of welding reports. Print or
download the reports in memory or switch memory
control off. Without memory control, a new report
overwrites the oldest existing one.
c. Welding Process
Temperature low
The heating element temperature will be increased
automatically.
Temperature high
The heating element temperature will be reduced
automatically.
Error Changeover
It took too long to retract the heating element and bring
the pipes to joining; welding will have to be repeated.
Error Drag Pressure
Impossible to determine the drag pressure; maybe pipes
will have to be clamped once again; or the pressure is
below 1 bar, which is not feasible for technical reasons.
Error Build-up Pressure
The build-up pressure is too high or too low and was not
re-adjusted in time.
Error Heat Soak
Pressure
The heat-soaking pressure is too high and was not
re-adjusted in time.
Error Joining Pressure
The joining pressure is too high or too low and was not
re-adjusted in time.
Cooling Stopped
Operator has stopped the cooling time by pressing the
STOP/REST key.
Error Plate Temperature Heating element temperature is out of tolerance;
impossible to re-adjust the temperature; maybe the
ambient temperature was too low.
