Operation with Keypad L240/PT
6.1 General information
The display and the buttons are illuminated as soon as a button is operated.
The lighting switches back off as soon as button
X
is pressed.
The operation/programming is divided into different levels:
1.
Operation by the operator without previous entry of the PIN code
(access level 0)
2.
Operation by the operator with previous entry of the PIN code
(access level 1)
3.
Operation by the Engineer with additional entry of the Engineer PIN
code (access level 2)
4.
Programming by the Engineer with additional entry of the Engineer
PIN code
5.
Management of the chip key/keypad code with additional
management PIN code entry
In principle, each button is assigned with a function on every level.
On each
level, in which you are operating, there are buttons directly accessible, i.e. it
is unnecessary to use the arrow keys to work through the menus, but you
can
do so in order to view the individual functions.
In every level you can
access all possible alternatives and further information with the assistance of
the “Help”
?
key.
A menu can be exited with button
X
and you access a higher level;
entries/changes performed are then automatically accepted.
If an entry is not made within 30 s, the menu will be automatically exited.
For the operator/user a maximum of 14 menu items are available that can be
selected by entering a 2-digit entry.
A part of the menu is only available after
entry of a PIN code or only appears when the corresponding bus modules
are connected.
When a menu selection has been made, the options yes/no or on/off can be
selected with the buttons
0
for off and no, and
1
for on and yes.
After an option of this type has been set, it is active, i.e. it is unnecessary to
press the
!
button (with the exception of the setting of date and time).
A menu can be exited with the button
X
.
Generally, the keypad exits an
access level if a button has not been pushed for about 30 seconds.
After an alarm,
this display is shown as soon as you log in with the 4-digit
PIN code.
Using the arrow buttons
><
, you can page through several
pages; the first alarm, which has occurred, is identified with “1”.
You can exit these messages with
X
and are shown the display: “
4
= Reset”.
The reset is carried out with the
!
button.
The alarm is deleted.
A
battery or mains fault
display can be delayed by up to 15 minutes.
The
LED flashes and the transistor output “Fault” assumes a high resistance
state (switches with no fault).
An external alarm is not triggered.
With a mains fault the panel can not be set externally, internal setting is
however possible.
The fault is deleted automatically when the mains voltage
recovers.
A battery fault points to a defective battery and leads to setting prevention
(external and internal).
It can only be deleted by a tamper reset.
