Operating instructions

A3G910-AV02-35

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
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 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

Instructions for cleaning

Check the unit regularly, with particular attention to smooth operation
and dust buildup on the impeller and motor housing.

Heavy dust buildup, especially on the motor housing and the
impeller, and/or strong vibrations, can destroy the fan. In this case,
switch off the fan immediately and clean it.

If heavy corrosion is identified on load-bearing or rotating parts of the
unit, switch it off without delay and replace it. Repair of load-bearing or
rotating parts is not permitted.

Only clean the unit when it is stopped; disconnect it from the power
supply and secure it against restarting.

Do not use aggressive cleaning agents!

Only direct water jets at the rotor side, never at the motor side.

Avoid directing the water jet at the condensation drainage hole.
Maximum water pressure: 80 bar

After cleaning, run the fan for at least an hour at maximum speed.

Make sure that the condensation drainage hole (if present) is not
obstructed by dirt.

If cleaning does not eliminate vibrations, the fan may need to be
rebalanced. To have it rebalanced, contact ebm-papst.

The fan is equipped with maintenance-free ball bearings. The lifetime
lubrication of the ball bearings is designed for a service life of 40,000
hours. If bearing replacement is necessary after that period, contact
ebm-papst.

Adjust maintenance intervals to the level of dust exposure.

6.2 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.
