ciple
a)
Once the Robacta TC is connected to the mains power supply, the Mains
voltage indicator (page 28) lights up. The capacitors, which store energy for
the cleaning operation, are discharged and no outputs are activated.
NOTE!
The following prerequisites must be met before the capacitor charging pro-
cess can begin
▶
Robacta TC 1000
▶
Device connected to the mains and the robot control
▶
The Quick Stop signal has been set
▶
Robacta TC 1000 ext.
▶
Base unit connected to the mains and the robot control
▶
Cleaning unit interconnecting hosepack connected to the base unit
▶
The Quick Stop signal has been set
b)
The device temperature is checked before the capacitors are charged. If it
lies within the tolerance range, the capacitors are charged.
If the operating temperature is exceeded, the Overtemperature indicator
(page 28) lights up. If this is the case, the capacitors are only charged once
the device has cooled down to the permissible operating temperature.
c)
Once the capacitors have been charged, the Ready signal is transmitted to
the robot control - the Ready-to-clean indicator (page 28) lights up. The
cleaning operation (discharge process) can now be initiated by means of the
Cleaning Start signal. For adjustment purposes, the cleaning operation can
also be manually triggered using the Discharge key button (page 28).
d)
Once the cleaning operation is complete, the program sequence restarts by
checking the device's temperature. If a problem occurred during the cleaning
operation, the Error. signal is output. The Robacta TC initiates the capacitor
charging process again. Once ready to discharge (Ready ), a second cleaning
operation can be started.
e)
Automatic refilling of the dipping bowl from the "Robacta TC Cool / Robacta
TC Cool MD" parting agent container ensures the optimum fill level. After
draining the "Robacta TC Cool / Robacta TC Cool MD" parting agent contain-
er, the fill level in the dipping bowl drops. The level sensor detects that the
level has dropped too low and the Fill level indicator (page 28) lights up. At
the same time, the Fluid Level Control signal is transmitted to the robot con-
trol.
-
The cleaning function of the Robacta TC remains available even if the Fill
level indicator (page 28) is illuminated.
NOTE!
If the robot control deactivates the Quick Stop, signal during the program se-
quence, the Robacta TC program sequence is interrupted immediately.
For safety reasons the capacitors are discharged via the cleaning coil.
