Subject to change without notice
Always replace all filter mats for the air inlet and outlet openings together.
1. When carrying out replacement, disconnect the MSC800 from the supply voltage so that
the fan wheels are safely shut down.
2. Loosen all covers of the air inlet and outlet openings on both sides of the cabinets and
fold downwards (by a maximum of 70°).
3. In order to release the lock, use your finger to carefully pull the blue function logo in the
louvered grills slightly upwards.
4. Remove used filter mats and replace each with a new filter mat. Insert the new filter
mats in the correct lateral position in the recess. The compressed side of the filter mat
points to the fan wheel.
5. Fold up the covers again and carefully press down until the lock audibly engages.

7.3 Cleaning optical effect surfaces on sensors
Depending on how the reading system is equipped, sensors may be installed with optical
effect surfaces (MLG, read cycle photoelectric sensors). Contamination on these sensors
can result in faulty switching behavior.
To avoid faulty switching behavior, remove contamination from the optical effect
surfaces of the sensors.
7.4 Checking incremental encoder
When using an incremental encoder, the position of the friction gear on the drive
technology must be checked regularly.
Make sure that the incremental encoder is in direct and secure contact with the drive
technology and that the friction gear is not slipping as it turns.
