cess and displays the error. However, this is only possible when welding
according to the electrofusion process or the WeldControl mode of
the butt-welding process. In the Manual Mode of butt welding, error
detection is not available.
The error that made the welding abort is displayed on the screen (see
Display 35). 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

Error while entering data with the alphanumeric and 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 or heating element/machine
chassis. 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 recommended next service date for the welder is overdue. The
service due message has to be acknowledged by pressing the START/
SET key. Send the welding system to the manufacturer or an
approved service point for service and check-up.
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 – 20°C to + 60°C.
Outside temperature outside the range from – 20°C to + 60°C.
The input voltage to the hydraulic and control unit is < 185 V; the
welding process, if started, will likely be flawed and should not be
started or repeated if the error appears during welding..
The input voltage to the hydraulic and control unit is > 280 V; the
welding process, if started, will likely be flawed and should not be
started or repeated if the error appears during welding.
The temperature of the control and hydraulic unit is too hot. Let the
welding system cool down for about 1 hour.
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.
There is no properly established electric contact between the
welding unit and the fitting (check push-on terminal on fitting), or
the heater coil is defective.
The optional tag printer is not ready (possible reasons: 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.
