WARNING
Faults in operation
Deviations from normal operation such as increased power consumption, temperatures or
vibrations, unusual noises or odors, tripping of monitoring devices, etc., indicate that the
machine is not functioning properly. This can cause faults which can result in eventual or
immediate death, serious injury or material damage.
● Immediately inform the maintenance personnel.
● If you are in doubt, immediately switch off the motor, being sure to observe the system-
specific safety conditions.
NOTICE
Risk of corrosion due to condensate
Humid air can condense inside the machine during operation as a result of intermittent duty
or load fluctuations. Condensate can collect inside the motor. Damage such as rust can result.
● Make sure that any condensation can drain away freely.
NOTICE
Non-periodic duty
In all of the operating modes, always operate the external fan according to DIN EN 60034-1.
For non-periodic operation, it is possible that the machine is thermally overloaded. This can
result in damage to the machine.
● In the case of extended non-operational periods, the fan should be in operation until the
machine has approximately reached the temperature of the coolant, see S2 duty type in
DIN EN 60034‑1.
● Use a suitable circuit to ensure that the external fan is appropriately operated.
NOTICE
EC fan control via an input signal
The fan motor can overheat if the external EC fan is operated at low fan speeds as a result
of the setpoint signal it receives.
● Monitor the motor using the integrated temperature sensors.
● Integrate the temperature monitoring into the interlocking circuit.
