5.4. Connecting a sensor
5.4.1. WL configuration
EN
There is no need for any physical connections if using
the product with a Dynafor
WL.
5.4.2. RS configuration
If using the product with a Transmitter RS, then a
4x0.25mm² shielded cable is needed for the connection,
following the connection diagram in figure 2 and using
the designated terminal blocks. See also the connection
diagram for the Transmitter RS in the manual.
NB: The RS485 bus is multidirectional. This
means the number of cables required can be reduced by
using the connection box to interconnect multiple pieces
of equipment. See the cabling diagram in figure 3.
Example: 2x RS485 cables linked to a connection box
and 1x RS485 cable between the connection box and
the product.
NB: The connection between the product
and any sensors should be under 100 m. Check the
continuity of the shielding and remove any loops. The
cable must be physically kept away from power cables.
5.5. Connecting an accessory
If using the product with an AL63, the latter needs to be
configured in "Slave" mode. Please see the respective
manual.
A 4x0.25mm² shielded cable is needed for the
connection, following the connection diagram in figure
2 and using the designated terminal blocks. See also
the connection diagram for the AL63 in the manual.
NB: Unplug the white no. 1 (VBUS) cable
from the RS485 bus on the AL63 side if connecting a
Dynafor
AL63 and DMU. See figure 2.

NB: The RS485 bus is multidirectional. This
means the number of cables required can be reduced
by using the connection box to interconnect multiple
pieces of equipment. See the cabling diagram in
figure 3.
Example: 2x RS485 cables linked to a connection box
and 1x RS485 cable between the connection box and
the product.
NB: The connection between the product and
any accessories should be under 100 m. Check the
8
Pro, Expert or Transmitter
TM
continuity of the shielding and remove any loops. The
cable must be physically kept away from power cables.
5.6. Connecting relays and alarms
NB: The No. 6 relay is not programmable and
monitors the network status. If the signal with a sensor
is lost, the sensor changes status.
NB: The alarm connectors are powered once a
programmed threshold has been exceeded.
Connect the product's relay connectors to the control
circuit as in figure 2. The relays are not active until the
thresholds have been set. Refer to the 5.9.14 after
installation.
Interrupting capacity of the changeover relays: 4A /230
V AC.
5.7. Starting up the sensors and
accessories
If the configuration is made with wireless sensors
(Transmitter WL, Pro or Expert), always switch on
the sensor(s) and accessory/accessories before
switching on the product. Otherwise, the product
will not be able to establish the radio link.
When using a configuration with wired sensors
(Transmitter RS), the sensor or sensors automatically
turn on when the product is started.
Likewise, always switch on the accessory /
accessories (HHD handheld device or AL63 large
display unit in slave mode) before switching on the
product.
NB: See the sensor, HHD and AL63 manuals for
information on starting up.
NB: If using a time-delay relay as specified in
paragraph 5.3, it is not necessary to switch on the AL63
before the product. The main ON/OFF button on the
AL63 must, however, always be switched on.
5.8. Starting up the product
NB: The product must only be started after the
product has been properly installed.
NB: It is possible to establish a network
composed of a maximum of four sensors and three
accessories.
