by the pipe or fitting manufacturer, a cool-on time may be required
during which the new joint must not be exposed to external forces.
This, however, is not monitored by the hydraulic, control, and data
logging unit, for which the welding has to be considered finished
when the 7 LED is lit.

4.4.8 End of Welding

The welding is finished at the end of the successful joining and cool-
ing stage. The welder can then releases the pressure.

Aborted Welding Process

If an error condition is detected, the welding process aborts and the
error is displayed.
The error that made the welding abort is displayed on the screen (see
Display 32). Additionally, in the welding diagram the LED that belongs
to the welding stage with the malfunction starts flashing.
The errors listed in the following table can be displayed on the
screen.

Error while entering data with the cursor keys.
Error while reading data from a bar code or an RFID card.
The welding system has to be disconnected immediately from both
the power supply and the fitting. The auto-test has detected an
error in the system. The welder must no longer be operated and has
to be sent to an approved shop for check and repair.
The internal clock of the machine is defective; re-set the clock in the
Configuration Menu.
The last welding is incomplete. The welding unit was disconnected
from the power supply voltage while it was in progress. To go on
using the unit, this error has to be acknowledged by pressing the
STOP/RESET key.
Outside temperature outside the range from – 10°C to + 50°C.
Outside temperature outside the range from – 10°C to + 50°C.
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
an authorized 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.
Heating element temperature will be increased automatically.
Heating element temperature will be reduced automatically.
It took too long to retract the heating plate 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.
