Errors During Welding - Rothenberger ROWELD ROFUSE Print+ V2 Instructions D'utilisation

• Input Error
A code that was entered is incorrect. At manual welding parameter input, no welding time was
entered. An incorrect value was selected in the date setting.
• 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.
• Download Cancelled
During data transfer or printing, an error condition occurred which could not be cleared.
• GPS Module Not Ready (only in model version with GPS module)
The minute that you have to wait from switching the GPS module on to the actual recording of
the geo-data is not over yet.
• No GPS Signal (only in model version with GPS module)
There is no reliable signal from the relevant satellites to the GPS antenna of the module.
• Poor GPS Signal (only in model version with GPS module)
The signal strength is so weak that no precise position can be recorded. Repeating the recording
is recommended.

Errors During Welding

All errors that occur while welding is in progress are also indicated by an audible alarm.
• Low Voltage
The input voltage is below 175 volts. If the error condition persists for longer than 15 seconds,
the welding process will be aborted. If the voltage goes down below 170 volts, the welding
process will abort immediately.
• Overvoltage
The input voltage is over 290 volts. If the error condition persists for longer than 15 seconds, the
welding process will be aborted.
• Resistance Error
The resistance value of the connected fitting is out of the read tolerance.
• Frequency Error
The frequency of the input voltage is out of tolerance (42 Hz - 69 Hz).
• Voltage Error
Check generator voltage and current. The output voltage does not correspond to the value
previously read; the welding unit has to be sent to the manufacturer for check-up.
• Low Current
The message is displayed if the there is a momentary current failure or if the current decreases by
more than 15% per second for 3 seconds.
• Excess Current
The output current value is in excess; possible causes: short-circuit in the heater coil or the
welding cable. During the start stage the upper abort threshold equals 1.18 times the value at
start, in any other case the upper limit depends on the load value and is calculated as the current
at start plus 15%.
• Emergency Off
The welding process has been interrupted by pressing the STOP/RESET key.
• Heater Coil Error
The dynamic current value during welding differs by more than 15% from the required value,
indicating a short-circuit in the heater coil.
• Power Supply Failure at Last Welding
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 (see also Sect. 9.4).
