Troubleshooting Machine with "WE..." in the model designation: - Overload protection: The electronic signal display (6) lights up and the load speed decreases dramatically. The motor temperature is too high! Run the machine in idling until it cools down and the electronic signal display switches off. - Overload protection: The electronic signal display (6) lights up and the load speed decreases slightly. The machine is overloaded. Work with a reduced load until the electronic signal display goes out. - Electronic safety stop: The electronic signal display (6) lights up and the machine was SWITCHED OFF automatically. If the slew rate of the current is too high (for example, if the machine suddenly seizes or kickback occurs), the machine switches off. Switch off the machine at the trigger switch (8). Switch it on again and continue to work as normal. Try to prevent the machine from seizing. See Section 4.2. - Restart protection: The electronic signal display (6) FLASHES and the machine does not start. The restart protection is active. If the mains plug is inserted with the machine switched on, or if the power supply is restored following an interruption, the machine does not start up. Switch the machine off and on again. - When switched on, the machine accelerates to maximum speed very quickly, i.e. automatic restriction of the starting current does not work (soft start). An electronic error exists. Other safety-related electronic functions are no longer available. Have the machine repaired immediately (see 12.). W 22-180 MVT, W 22-230 MVT, W 24-180 MVT, W 24-230 MVT, W 26-180 MVT, W 26-230 MVT: - Switching on the machine reduces the voltage briefly. Unfavourable mains power conditions may have a detrimental effect on other machines. Power impedances less than 0.2 ohm should not cause malfunctions. 11.
