Operation
Machine protection
Starting current limitation
The electronically controlled soft start ensures a
smooth start of the machine. Due to the low starting
current of the machine, a 16 A fuse is sufficient.
Temperature-dependent overload
protection
To protect against overheating, the safety electronics
switch to cooling mode when a critical temperature
is reached. The machine then continues to run for
approx. 1300 min
-1
and the constant electronics
are deactivated. After a cooling time of approx. 10
to 20 seconds, the machine is ready for operation
again.
▸
Switch the machine off and on again to activate
the constant electronics. The temperature-depen-
dent overload protection reacts accordingly ear-
lier when the device is at operating temperature.
Low voltage protection / restart protection
3
The machine stops if the supply voltage briefly
fails (disconnected plug, unstable supply network,
etc.).
▸
After restoring the supply voltage, the machine
must be switched off and on.
3
The machine is ready for operation.
