As soon as the cleaning device is connected to the grid, the
(page 30) lights up. The capacitors, which store the energy for the cleaning process,
are discharged and no outputs are controlled.
NOTE! In order for the capacitors' charging process to begin, the following pre-
requisites must be met:
- Base unit connected to the grid
- Base unit connected to the robot control
- Interconnecting hosepack of cleaning unit connected to the base unit
- The 'Quick Stop' signal must be set
Before the capacitors are charged, the device temperature is checked. If it is within
tolerance, the capacitors will be charged for the cleaning process.
If the operating temperature is exceeded, the overtemperature
dication (page 30) will light up. In this case, the charging process of the capacitors
will only take place after cooling down to the permissible operating temperature.
After 20 seconds of charging time, the 'Ready' signal will be output to the robot control
– the Ready to clean indication
as the capacitors are fully charged, the indication will light up permanently. Although
after 20 seconds the maximum magnetic flux density is not yet available to the device,
the cleaning process (discharge process) can be initiated by means of the 'Cleaning
Start' signal. For setup purposes, the cleaning process can be triggered manually by
means of Discharge button
After 50 seconds of charging time, the maximum magnetic flux density is available for
the cleaning process.
For the exact ratio of charging times to available magnetic flux density, please see the
diagram below.

After the cleaning process has finished, the program sequence starts again with a
check of the device temperature. If a cleaning process has finished incorrectly, the 'Er-
ror' signal will be output. The cleaning device once again initiates the charging process
of the capacitors. If the cleaning readiness is 'Ready', another cleaning process can
be carried out.
