I/O modules

General

Washing machines may be equipped with either one or two I/O modules:
• I/O module 1 controls internal machine functions and is always instal-
led in the machine prior to delivery. It controls outputs to water valves,
waste discharge and heating.
• I/O module 2 is installed as an optional extra, controlling the external
functions of the machine, i.e. inputs from payment and booking sys-
tems and outputs to detergent pumps.
The functionality of I/O module inputs and outputs is dependant on the
parameter software downloaded to the machine's program device. The
function options for the I/O modules are indicated by a letter in the pro-
gram designation for each module and, together with the article number
of the parameter software, shown in the ARTICLE NUMBER menu of the
service program as per the following example:
Program designation
Article number shown in the
service program
If the second letter (I/O module 2) appears in lower case, it means that the
machine is not fitted with I/O module 2 but the downloaded parameter
software is I/O module 2 enabled.
Program designation
Article number shown in the
service program
If the machine subsequently fitted with I/O module 2, the module will ac-
quire the function option as specified by the second letter once the new
I/O module has been addressed.
