- Once the cleaning device is connected to the mains power supply, the mains voltage
indicator lights up. The capacitors, which store energy for the cleaning operation, are
discharged and no outputs are activated.
- The device temperature is checked before the capacitors are charged. If it lies within
the tolerance range, the capacitors are charged in preparation for a cleaning opera-
tion. If the operating temperature is exceeded, the overtemperature indicator lights up.
Capacitor charging only begins once the temperature has fallen to the permitted op-
erating temperature.
- The "Ready" signal is output to the robot control after twenty seconds of charging - the
"Ready-to-discharge" indicator on the device begins to flash. When the capacitors are
fully charged, the light remains permanently on. Although the device has still not
achieved maximum magnetic flux density after just twenty seconds, the cleaning op-
eration (discharge process) can still be triggered using the "Cleaning Start" signal. For
adjustment purposes, the cleaning operation can also be manually triggered using the
discharge button on the device.
The maximum magnetic flux density for cleaning is available after fifty seconds of
charging.
See the diagram below for the exact relationship between charging time and the mag-
netic flux density available.
- Once the cleaning operation is complete, the program sequence restarts by checking
the device's temperature. If there was a problem during the cleaning operation, the
"Error" signal is output. The cleaning device resumes charging the capacitors. Once
ready to clean ("Ready"), a second cleaning operation can be started.
NOTE! Before the capacitors can be charged, the cleaning device must be con-
nected to both the mains power supply and the robot control. The "Quick Stop"
signal must also be set.
