LC display:
Data, service intervals and menu options are shown in the two lines of the illuminated LC display
(LCD = “liquid crystal display”). The current menu option appears in the upper line. The lower line
contains the current parameter value for dispensing, according to numerical data to be modified.
Keypad with 12 softkeys:
Menu options to control the system are selected by means of these keys.
Details for changing parameters etc. are explained in a following chapter (see paragraph 4.4,
page 25).
Control lamp for First Drop (“function”):
This red LED indicates, if there is a problem during the first drop adjust. It is also ON during the
start-up of the MDC, while the power supply unit is initialized.
Control lamps for adjust (“green” and “red”):
During the adjust, these two control lamps indicates the adjust result that is internally monitored:
• Green: the adjust value is OK. Press [Enter]-key to confirm it.

You can de-/activate the control lamps for adjust. It makes no difference during the adjust (as
above). But it affects the lamps outside of the adjust (as below).
Outside of the adjust: (if the control lamps for adjust are activated)
• Red: the MDC detects an error.
• Green: the valve detects that the adjust value falls inside the adjust range.
Outside of the adjust: (if the control lamps for adjust are deactivated)
• Red: the MDC detects an error (except for an adjust error).
• The green adjust-LED stays OFF.
To de-/activate the control lamps for adjust, enter the service code 1100 (see paragraph 4.5.6
"Submenu “Service-Option”", page 33). Alternatively, you can use the serial command
SETADJLED:OFF/ON (see paragraph 8.1.2.2 "Explanations", page 88).
Control lamp for status of heating:
This red LED indicates the activity of the heating.
Heating activated – LED ON
Heating deactivated – LED OFF
