Operating instructions
K3G250-RR03-M4
Siemens AG PD LD Nbg.
Translation of the original operating instructions
Line voltage faulty Check line voltage,
restore power supply.
Attention! The error
message resets
automatically.
Device restarts
automatically without
warning.
Faulty connection Isolate from supply,
correct connection;
see connection
diagram.
Broken motor winding Replace device
Thermal overload
protector activated
Allow motor to cool
off, locate and rectify
cause of error,
release restart lockout
if necessary
Deficient cooling Improve cooling. Let
the device cool down.
To reset the error
message, switch off
the line voltage for at
least 25 s and then
switch it on again.
Alternatively, reset
the error message by
applying a control
signal of < 0.5 V to
Din1 or by shorting
Din1 to GND.
Ambient temperature
too high Reduce the ambient
temperature. Let the
device cool down.
To reset the error
message, switch off
the line voltage for at
least 25 s and then
switch it on again.
Alternatively, reset
the error message by
applying a control
signal of < 0.5 V to
Din1 or by shorting
Din1 to GND.
Impermissible point of
operation (e.g. back
pressure too high) Correct the operating
point. Let the device
cool down.
To reset the error
message, switch off
the line voltage for at
least 25 s and then
switch it on again.
Alternatively, reset
the error message by
applying a control
signal of < 0.5 V to
Din1 or by shorting
Din1 to GND.

6.1 Vibration testing
Checking of fan for mechanical vibration based on ISO 14694.
Recommendation: Every 6 months. Max. vibration severity is 3.5 mm/
s, measured at the motor fastening diameter on the motor support plate in
the direction of the motor axis of rotation and perpendicular to this.
Fig. 1: Example illustrating vibration measurement. The arrangement of
the sensors depends on the device concerned and the installation
situation.
6.2 Cleaning
NOTE
Damage to the device during cleaning
Malfunction possible
→ Do not clean the device using a high-pressure cleaner.
→ Do not use acid, alkali or solvent-based cleaning agents.
→ Do not use any pointed or sharp-edged objects for cleaning
6.3 Safety inspection
NOTE
High-voltage test
The integrated EMC filter has Y capacitors. The tripping current
is exceeded when AC testing voltage is applied.
→ Test the device with DC voltage when you perform the
legally required high-voltage test. The voltage to be used
corresponds to the peak value of the AC voltage required by
the standard.
