2.5 Equipment Settings
(Menu Structure)
Via the menu, the UL 200 may be adapted to prevailing
ambient and operating conditions in a flexible manner. In
order to provide a better overview, the menu has been
divided into three parts. The individual menu items are
numbered consecutively.
The first part - the basic menu - contains functions
(No. 1 ... 9) which can be changed frequently and quick-
ly when running a particular application.The second part
- the extended menu - (No. 10 ... 49) permits access to
those parameters which may have to be changed only
once during initial start-up or in the case of changed
ambient conditions, i.e. parameters which have to be
changed only rarely. The third part - the service menu -
(No. 50 ... 99) is used for servicing the UL 200 or for assi-
stance during troubleshooting.
For reasons of clarity, only the basic menu is generally
accessible. The extended menu can be accessed after
entering a password in menu item No. 9.
The service menu can be accessed by pressing the Ser-
vice push-button (4/12). When only wanting to display
internal parameters of the instrument, the scroll push-
button may be operated to move between the menu
items of the service menu without necessarily having to
enter the second password. However, if modifications are
to be made here or for access to further test modes, the
entry of the correct second password is required (with
the exception of menu item 81). This password will only
be made available after suitable training by Leybold.
2.5.1 Entry of Equipment Parameters
Pressing the MENU push-button (4/7) enters the menu
mode. Refer also to Chapter 2.4.3.
The menu items are selected by operating the SCROLL
push-button (4/5).The individual menu items are numbe-
red consecutively. Pressing the upper symbol of the
push-button decrements the menu item number by 1 (i.e.
visually one passes through the menu table to the top)
and operation of the lower symbol of the push-button
increments the menu item level by one.When arriving at
the end of the menu items, menu item „1“ is then selec-
ted automatically.
Those parameters which can be modified within a menu
item are displayed flashing. At first the currently valid
value of the parameter is displayed. The corresponding
values may then be changed through the VALUE push-
button (4/6). Each value which has been changed must
then be acknowledged by operating the ENTER push-
button (4/8) so that the UL 200 accepts and stores the
newly changed value. At the same time, the next para-
meter which can be changed is selected or the message
„Updating Parameter“ is displayed.
Pressing the MENU push-button (4/7) once more exits
the menu mode.
All parameters which are essential for proper operation
remain stored when the instrument is disconnected from
the mains.
A detailed example describing the way in which a para-
meter is changed is given in Chapter 2.5.4 under
„01:Trigger“.
Note
If the message „Keyboard locked“ is displayed when try-
ing to change a parameter, this means that access to the
keyboard has been restricted. At this moment further
entries can not be made. The keyboard must be
unlocked first. For this refer to menu item „14: Control
by“.
2.5.2 Password
In menu item 09 the operator is asked for the entry of a
password in order to be able to access the further menu
items (10 to 49).
The default password as entered in the factory is 0013.
Note
The password may be changed by the operator at any
time. The password should be kept at a secure place.
Entry of the password
This entry is performed digit by digit through the VALUE
push-button (4/6) and the ENTER push-button (4/8).
When selecting menu item 09 for the first time, the mes-
sage „locked“ will be displayed flashing to the right.
Pressing the VALUE push-button (4/6) lets the first digit
of the password which is to be changed, flash. Pressing
this push-button once more increments or decrements
the displayed number starting at „0“. Acknowledge the
desired number by operating the ENTER push-button
(4/8). As soon as this has been done, the next digit is
shown flashing. This number too, is changed by opera-
ting the VALUE push-button and acknowledged by ope-
rating the ENTER push-button.
All four digits are entered in this manner.
After having operated the ENTER push-button (4/8) for
the fourth time, the check starts. The message „Pas-
sword OK“ or „Password failed“ will appear for 2 se-
conds. In the case of an incorrect password, „locked“ will
be displayed once more. In the case of the right pass-
word the message „opened“ will appear.
Access to the protected functions remains possible until
the password is changed. Access to protected functions
remains possible even if the instrument has been dis-
connected from the mains in the mean time.
