Figure 3.1 Jumpers on ICU board
Protection level 2
All NOVRAM items which affect the (remote) level reading (such as reference level (
RL
) or transmission
address (
TA
)) are protected by password 2 (
W2
). It is possible to modify these data only after entering the
correct password W2=XXXXXX , where XXXXXX is the level 2 password. Additional measurement-related
items, such as temperature items can also be protected by password 2.
Password
W2
itself can be read protected by means of jumper J2 on the ICU board.
In protection level 2, the items protected under protection level 1 can be also modified.
Figure 3.1 shows the jumper position on the ICU board. The
table below gives an overview of the ICU jumper functions.

Indexed items
In general, items have only one setting (i.e. HA+026.0000). Indexed items have more than one setting
(elements). For instance: item
OS
(obstruction zone start position). Item
OS
has ten elements,
corresponding with the ten programmable obstruction zones.
OS OS OS OS OS OS OS OS OS OS
element 0 element 1 element 2 element 3 element 4 element 5 element 6 element 7 element 8 element 9
Indexed items are requested by the two-character item name, followed by the element number and number
of elements to be requested, separated by dots.
In general:
XX.n.i
where: XX = two-character item name
n = element number (starts with 0)
i = number of elements (can be 1 or more, but maximum is 9)
For example:
OS.0.1
<enter> requests the first obstruction zone start position;
OS.1.1=+012.3400
<enter> programs the second obstruction zone start position.
Note:
Although it is possible to program more than one element at the time, it is not recommended. To avoid
mistakes, program only one element at the time.
