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.
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.
Outside temperature not within the range from – 20°C
to + 60°C.
Outside temperature not within the range from – 20°C
to + 60°C.
The temperature of the control and hydraulic unit is too
hot. Let the welding system cool down for about 1 hour.

defective; where possible, check the connections/plug;
have the machine inspected by a qualified service shop if
needed.
The optional printer is not ready (possible reasons also: no
communication or faulty cable).
During data transfer or printing, an error condition
occurred which could not be cleared.
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.
The heating element temperature will be increased
automatically.
The heating element temperature will be reduced
automatically.
It took too long to retract the heating element and bring
the pipes to joining; welding will have to be repeated.
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.
The build-up pressure is too high or too low and was not
re-adjusted in time.
The heat-soaking pressure is too high and was not
re-adjusted in time.
The joining pressure is too high or too low and was not
re-adjusted in time.
Operator has stopped the cooling time by pressing the
STOP/REST key.
impossible to re-adjust the temperature; maybe the
ambient temperature was too low.
