4.5 Menu Structure

The main menu of the control unit MDC 3500 contains 5 submenus: “Pulse Parameters”,

“Cooler/Heater”, “Status”, “Scenario” and “Service-Option”. With the [enter]-key you can reach

the level of the submenus. There you can switch around with the keys [→] and [←]. Another

option from the main menu is to use [→] or [←], which allows you to gather some information

about the system, like maintenance situation or ID numbers. The items are “Tappet”, “Nozzle”,

“Date/Time”, “MDC ID”, “Valve ID” and “Firmware Rev.” “Firmware Rev.” will give you the current

revision of the firmware on your MDC. “Date” gives the current date and time (as UTC), as the

MDC has a real time clock (RTC). Menu levels are always “wrap-around”, i.e. you can move on

from the last item in a menu directly on to the first. With [esc] or [↑] you can change from a sub

menu into the next higher menu level.

The information shown in the display differs, depending on the menu level (see paragraph 4.5.1,

page 28).

• Dispensing parameters for a particular process can be recalled and modified in the submenu

“Pulse Parameters”.

• “Cooler/Heater” – select the settings for the heating and the valve cooling, if set up.

• You can use the submenu “Status” to decide on individual cycles for the replacement of

tappet and nozzle insert (see paragraph 4.5.4 "Submenu “Status”", page 34). The current state

of the system with respect to the maintenance interval can be verified by the function “Maint.

Cycle” (see paragraph 10.1 "Maintenance Indicator", page 137). With “Maint. Message” you

can decide to show maintenance messages or not. Error messages concerning the system are

shown with the function “Error”.

• In the submenu “Scenario” you can enter values for pre-defined scenarios. Here you can also

set the option to work with these scenarios.

• The submenu “Service-Option” is used to enter service codes and to change the baud rate.

4.5.1 Main Menu

When you switch ON the MDC, you always start in the “Main Menu”. The display shows “Ready”

(position 1, see Fig. 6). With [enter] or [↓] you can reach the submenus. For the information on

the main level use [→] or [←]. All levels are “wrap-around”, i.e. you can circle around between

the items with both keys.

INFORMATION

Automatic change back to the main menu

On this level, the display jumps automatically back to “Ready”, if you do not press any button for

longer than about 10 sec. From the submenus, the display will jump back as well, if no buttons

are pressed, but the wait is a bit longer.

In the upper right corner of the display a frequency is shown (position 2, see Fig. 6). This is the

dispensing frequency resulting from your current parameter settings. While “Scenario” is “ON”,

the word “Scenario” is shown instead (only while entering parameters in the submenu, the

frequency is always shown). Next to the frequency, on position 3, one or two letters show the

submenu you are in (PP = Pulse Parameters, CH = Cooler/Heater, S = Status, Sc = Scenario, SO =

Service-Option).

Fig. 6: Display main menu

In the lower line, a maintenance bar is shown (position 5). If all eight sections are filled,

maintenance is recommended. Though be aware that this bar is only updated when starting the

MDC!

In “Tappet” and “Nozzle” you can see the current values as well as the respective reference value.

If a heater is used, instead of “Ready” the current temperature is displayed.

4.5.2 Submenu “Pulse Parameters”

In the submenu “Pulse Parameters” you can recall and modify dispensing parameters for a

particular process. The limits for these parameters you can find in the diagram. You cannot enter

values outside these ranges. The values for rising and falling are for 80 % needle lift. If the needle

lift is smaller, the values might be lower. The dispensing frequency based on the current

parameters is shown in the main menu in the display (position 2, see Fig. 6, page 29), but only, if

“Scenario” is “OFF”.
