keys. To print a tag of the welding operation of which the abstract is
currently displayed, the label tag printer has to be connected to the
welder. Then press the START/SET key in the ViewWeld screen. The
printed label tag has a QR code (two-dimensional bar code), in which
information identifying the joint is encoded: date and time, report
number, welding system used, and joint status.
4.8 Aborted Welding Process
All parameters relevant to the welding are constantly monitored while
the welding process is running. If one or more of the parameters are
out of tolerance and the machine cannot adjust them within a speci-
fied delay, the welding process is aborted.
The error that made the welding abort is displayed on the screen (see
Display 26). 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.
Type of Error
Description
a. Data Input
Input Error
Error while entering data on the keypad.
Code Error
Error while reading data from a transponder card.
b. System
Clock Error
The internal clock of the machine is defective; re-set the clock in the
Configuration Menu.
System Error
Malfunction in the control system of the machine; power to the
machine has to be turned off and disconnected immediately, and the
machine has to be sent to the manufacturer or an authorized service
point for check and repair.
Pressure Sensor 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
an authorized service shop if needed.
Heating Sensor Defective
Temperature Sensor
Defective
Printer not Ready
(only label tag printer)
The optional printer connected to the machine is not ready (possible
reasons: no communication or faulty cable).
c. Welding Process
Temperature low
Heating element temperature will be increased automatically.
Temperature high
Heating element temperature will be reduced automatically.
Insufficient Voltage
The input voltage to the hydraulic and control unit is < 185 V; the
welding process is likely flawed, and repeating it is recommended.
Excessive Voltage
The input voltage to the hydraulic and control unit is > 280 V; the
welding process is likely flawed, and repeating it is recommended.
Error Changeover
It took too long to retract the heating plate and bring the pipes to
joining; welding will have to be repeated.
Ambient Temperature high
Outside temperature outside the range from – 5°C to + 50°C.
Ambient Temperature low
Outside temperature outside the range from – 5°C to + 50°C.
Error Drag Pressure
Impossible to determine the drag pressure (pressure to “drag” the
pipes along by setting the movable carriage in motion); maybe pipes
will have to be clamped once again.
Error Build-up Pressure
Computed maximum pressure that will be applied during welding is
too high; impossible to start welding; maybe pipes will have to be
clamped once again.
Error Heating Pressure
Heat-soaking pressure too high, could not be re-adjusted.
Error Joining Pressure
Joining pressure too high or too low, could not be re-adjusted.
