Operating instructions
Clean the device;
replace if unbalance
is still found after
cleaning. Make sure
no weight clips are
moved, damaged or
removed during
cleaning.
Switch off, de-
energise, and
remove mechanical
blockage.
Check mains power,
restore power
supply. Attention! The
error message resets
Mounting screws
automatically. The
of terminal box
device starts up
broken during
again automatically
closing
without advance
warning.
De-energise, correct
connection, see
connection diagram.
Replace device
7.1 Cleaning
Improve cooling. Let
the device cool down.
To reset the error
message, switch off
the mains supply
voltage for a min. of
25 s and switch it on
again.
Alternatively, reset
the error message by
applying a control
signal of <0.5 V to
7.2 Safety test
DIN1 or by short
circuiting Din1 to
GND.
Reduce the ambient
temperature. Let the
device cool down.
To reset the error
message, switch off
the mains supply
voltage for a min. of
25 s and switch it on
7.3 Maintenance interval
again.
Alternatively, reset
What has to

be tested?
applying a control
Corrosion
signal of <0.5 V to
DIN1 or by short
circuiting Din1 to
GND.
Impermissible
operating point (e.g.
excessive load, back
pressure too high)
If you have any other problems, contact ebm-papst.
NOTE
Damage to the device during cleaning
Malfunction possible
→ Do not clean the device using a water jet or high-pressure
cleaner.# Do not use any acid, alkali or solvent-
basedcleaning agents.# Do not use any pointed or sharp-
edged objects for cleaning
Regular cleaning of the device prevents unbalance caused by
deposits for example.
NOTE
High-voltage test
The integrated EMC filter contains Y capacitors. Therefore, the
trigger current is exceeded when AC testing voltage is applied.
→ Test the device with DC voltage when you carry out the
high-voltage test required by law. The voltage to be used
corresponds to the peak value of the AC voltage required by
the standard.
How to test?
Frequency
Visual inspection At least every
3 months
`
Correct the operating
point. Let the device
cool down.
To reset the error
message, switch off
the mains supply
voltage for a min. of
25 s and switch it on
again.
Alternatively, reset
the error message by
applying a control
signal of <0.5 V to
DIN1 or by short
circuiting Din1 to
GND.
Replace device
Which
measure?
When there is
strong
corrosion that
impairs the EX
protection, e.g.
in gap
surfaces,
replace the
device.
