Error report

If a fault appears, the red LED* flashes below the start button and the error code is shown on the display in
terms of a double figure. The meaning of these figures is described in the following
Error Meaning
code
1 Over current
2 Over temperature
3 Overload
4 Interrupt
5 Watchdog
6 Brown out
8 Maintenance rate exceeded
10 Intermediate voltage missing
11 Mains voltage too high
12 Mains voltage too low
13 Operation voltage too high
14 Operations voltage too low
The errors 10 - 14 must be accepted by pressing the red STOP button.
The errors 04 - 06 can not be accepted. It must be assumed that the motor control is damaged.
If the machine is connected to the electric mains, at first the data of the micro controller are transferred to
the display controller. This takes a few seconds. In this time the green LED* below the start button flashes.
As soon as the LED switches off, the machine is ready for operation.

button has to be pressed three times.
Charging circuit for uzw damaged
The machines is connected to too high voltage
(generator)
The machines is connected to too low voltage (generator)
The voltage is steady or momentary too high (generator,
or interference potential)
The voltage is steady or momentary too low (too long
extension cord, too low cross section, generator too
weak, or phase failure)
Operation hours until next service (maintenance)
Total number of operated hours
Number of switch on cycles
Number of switch off cycles
Software version number of motor control
Software version number of I/O-control
Machine type
Here the last occurred errors (max. 24) are shown. Thereby index and
error code are flashing. The last error code flashes in double frequency.
