Connecting Sensors
Number of Connectable Sensors
The number of connectable Sensors depends on the settings of communication units.
The Sensors that are allocated two unit numbers must be counted as two units when counting the
number of sensors.
Connecting and Identifying Sensors (Unit Number)
The Sensors are gang-mounted to the right side of the Communication Unit, as shown in
the following diagram. DIN track must be used for installing.
Power to the connected Sensors is supplied from the Communication Unit.
The Communication Unit identifies the connected Sensors according to the unit numbers.
Unit numbers of sensors are assigned to the units from unit number 1 starting from the
communication unit side. Note that some Sensors occupy two unit numbers.
