Errors During Welding - Rothenberger ROWELD ROFUSE Basic 48 Instructions D'utilisation

The welding unit has to be disconnected immediately from both the power supply and the fitting. The
auto-test has found an error in the system. The unit must no longer be operated and has to be sent to an
authorized shop for check and repair.
9.1.7 Temperature Error
The ambient temperature measured is outside the operating range of the welding unit, i.e., below –10°C
or above +60°C.
9.1.8 Temperature Sensor Defective
The ambient temperature sensor on the welding cable is damaged or defective.
9.1.9 Clock Error
The internal system clock works improperly or is defective. Reset the clock, or send the welding unit to
the manufacturer for check and service.
9.1.10 Next Service Due
The recommended next service date for your welding unit has passed. The "Next Service Due" message
has to be reacted to by pressing the START key. Please send the welding unit to the manufacturer or an
authorized service point for service and check-up.
9.1.11 Input Error
An incorrect range was selected in the date setting.
9.1.12 Memory Full
The system memory is full of reporting protocols. Print off the reports in memory or switch memory control
off. The oldest report will then be overwritten.
9.2

Errors During Welding

All errors that occur while welding is in progress are also indicated by an audible alarm.
9.2.1 Low Voltage
The input voltage is below 175 volts. The welding unit triggers the audible alarm. 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 be aborted immediately.
9.2.2 Overvoltage
The input voltage is over 290 volts. If the error condition persist for longer than 15 seconds, the welding
process will be aborted.
9.2.3 Resistance Error
The resistance of the connected fitting does not correspond to the value previously read.
9.2.4 Frequency Error
The frequency of the input voltage is out of tolerance (42 Hz - 69 Hz).
9.2.5 Voltage Error
Check generator voltage and current. The output voltage does not correspond to the value previously
entered; the welding device has to be sent to the manufacturer for check.
9.2.6 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.
9.2.7 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%.
