the cable must be moved accordingly, before you screw in the
detector. Do not place the housing cover on the detector until
you have finished the teach-in procedure (see "Configuration"
section); otherwise, the LEDs that are needed for the teach-in
procedure will no longer be visible.
After you put the housing cover on, seal both detector
components with the supplied stickers.
When connecting the wires, make sure that the command
wires are either insulated or connected to a fixed potential, to
prevent undesired execution of commands. Also make sure
that solely the installation contractor has access to the
command wire. Thus it must not be laid to the alarm control
unit.
The detector is encapsulated so that it meets protection class
IP 67, in accordance with IEC 529. The switch for removal
protection also has the same protection class.
Configuration
Note:
To configure the detector, it has to be connected to a
power supply.
Basics
– command types
The grade 4 magnetic detector has three different commands:
•
Learn-in the unit to the environment
•
Learn -in the unit to the magnet
•
Reset all values
All commands are triggered by a brief connection of the
command wire to the z
ero potential (“contact ground”).
Figure 11: Overview of learning phases
Standard learn-in procedure
Both learn-in commands must be executed to learn-in the
detector.
Learning-in the unit to the installation environment
Before learning the unit to the environment, make sure that
there are no devices or objects in the immediate vicinity of the
magnetic switch which could create a strong magnetic field and
disturb the detector in performing its functions. The magnet
that belongs to the detector may also not be located within the
immediate vicinity when you learn-in the detector to the
environment.
Note:
You can only learn-in the detector to the environment
when it is in the “Detector Reset” state. To reset the detector,
proceed as described in the “Resetting the detector” section.
To learn-in the unit to the installation environment:
1. Contact the command wire to ground to activate the learn-
in procedure for the environment.
2. The LED lights up red for several seconds to indicate that
the
“Learn-in Environment” command was selected.
3. The LED then starts to flash red for several seconds.
Contact the command wire to ground again to confirm the
command. If you do not want to execute the command, let
the confirmation time elapse.
4. If you confirm the command in time, the LED stops
flashing. The detector switches to the “Environment
Learnt-
In” state, in which you can learn-in the unit to the
magnet.
Learning-in the unit to the magnet
You can only learn-in the detector to the magnet when it is in
the “Environment Learnt-In” state. To learn-in the detector to
the environment, proceed as described in the
“Learning-in the
unit to the environment” section.
If an error occurred during the learn-in process of the unit to
the environment, the detector can be reset without having to
first learn-in the unit to the magnet.
This can be achieved by a brief disconnection of the power-
supply. Afterwards, proceed according to the
“Learning-in the
unit
to the installation environment” section.
Note:
The magnet must already be correctly installed at this
time. To improve visibility of the LED while selecting this
command, you can hold the magnet outside of its closed
position (open window/ door). In this case, be ready to
immediately return the magnet to its closed position when
required to do so.
To learn-in the unit to the magnet:
1. Contact the command wire to ground to activate the learn-
in procedure for the magnet.
2. The LED lights up green for several seconds to indicate
that the “Learn-In Magnet” command was selected.
3. The LED then starts to flash green for several seconds.
Contact the command wire to ground again to confirm the
command. If you do not want to execute the command, let
the confirmation time elapse.
4. If you confirm the command in time, the LED flashes more
quickly. Now return the magnet to its closed position (if it is
not already in that position). If the requirements are met,
the detector switches to the “Magnet Learnt-In” state, in
which the monitoring of the mag- net position and the
signal outputs are activated.
5. A red lamp indicates that the magnet was incorrectly
positioned or that the magnetic field is too small due to
other reasons. In this case, the detector remains in the
“Environment Learnt-In” state, and the unit must be learnt-
in to the magnet again.
Resetting the detector
A detector reset is required when you need to update the
previously learnt-in data or adjust the detector to a new magnet
or installation situation.
Note:
Once you reset the detector, all changes you made are
lost.
