Miscellaneous spare part
Parts that are listed in the spare part drawings in
addition to maintenance and servicing parts so as
to improve communications between the cus-
tomer and the manufacturer, but that are not
allowed to be ordered or replaced without first
contacting the manufacturer.
▪
The spare parts always required for maintenance of the controller are grouped together
into spare parts kits appropriate for the device in question. Each spare parts kit has its
own part number (part no.).
▪
Individual maintenance and servicing parts can be ordered using the corresponding
part number, which is specified in the bill of materials for the controllers. The required
number of maintenance or servicing parts is specified under the relevant part number
in the “Part No.” column. If no quantity is specified, this means that only one unit is re-
quired.
