The RWI65.02 can communicate with an active bus device (master) with the aid of
– the FLN (

AZI65.03
each card contains the electronic circuits required for communication.
The compartment be-comes accessible after opening the front door and removing the
cover. The communication card slides into its compartment in grooves. Fitting the FLN
communication card in the RWI65.02 requires no re-commissioning, but only bus
registration for data exchange on the network.
Eighty percent of the plastic materials used can be recycled. In place of NiCd batteries,
the controller has a super capacitor which requires replacement every two years and
improves operating safety and environmental protection.
The controller requires AC 24 operating voltage. The transformer must be suitable for
safety extra-low voltage (SELV), 100 % duty, and must have separate windings.
Fuses, switches, wiring and earthing must comply with all local safety regulations.
The limitations cannot be used as safety functions. These always require separate
safety devices.
All important variables required for commissioning
−
if known at the time of planning
−
must be indicated on the plant documentation (connection diagrams, etc.).
For additional information on the RWI65.02, please refer to the Reference Manual,
ordering no. CM2Z3204E. It contains application examples, detailed function
descriptions, a data point list for commissioning, safety notes, etc.
The controller has been designed for wall mounting (in an open space or inside a
control panel) or flush panel mounting (control panel front, console, etc.). Observe the
permissible ambient conditions. Begin by mounting and wiring the base. The cables
inside the base must be accommodated so that you can easily fit the card.
Secure fixing screws only after commissioning.
The controller is supplied complete with mounting instructions.
For commissioning, the Reference Manual, ordering no. CM2Z3204E, is required.
When commissioning the plant, check all functions of the controller and of the
communication card (if present) as well as the wiring of the connected units.
