Checking the incremental encoder
If an optional incremental encoder is used, the position of the friction wheel at the drive sys-
tem should be checked at regular intervals.
¾
Ensure that the incremental encoder has direct and fixed contact with the drive system
and that the friction wheel rotates without slipping.

Replacing a bar code scanner
Incorrect or damaged bar code scanners have to be removed and replaced with either new
or repaired bar code scanners.
Important
Repairs to the bar code scanner should only be carried out by qualified and authorised
SICK AG service staff.
8.5.1
Removing the bar code scanner
1. Switch the power supply to the bar code scanner off.
2. Disconnect all the connection cables on the bar code scanner.
3. Remove the bar code scanner from the holder. Mark the bar code scanner's situation
and alignment on the holder or environment.
8.5.2
Replacing the bar code scanner
1. Align and install the new or repaired bar code scanner (see
). Observe any marks made previously on the holder or the environment
chapter 8.5.1 Removing the bar code scanner, page 68
).
2. Reconnect connection cables to the bar code scanner (see
).
3. Switch the power supply to the bar code scanner back on.
The bar code scanner starts with the default setting.
4. If a parameter memory module CMC600 is used in connection module CDB620/
CDM420:
The bar code scanner automatically loads the current parameter set from the CMC600
into the permanent memory and, subsequently, is ready for operation.
- or -
Without parameter memory module CMC600:
Connect to the bar code scanner via the SOPAS-ET configuration software, transfer the
configuration stored on the PC via download to the bar code scanner and permanently
store the configuration there.
