6.2 Connecting the unit
Proceed as follows:
1. Connecting the supply voltage
a Connect the supply voltage to (A1, A2).
Please note the following:
The power supply must meet the regulations for extra low voltages with protective
separation (SELV, PELV).
The cables for the unit's supply voltage (A1, A2) must be fitted with a 4 A fuse,
characteristic B/C.
2. Connecting the operating mode interface's semiconductor outputs
a Connect the operating mode interface's semiconductor outputs to a control system
that supports "1ooN" evaluation.
You must read the information concerning intended use (see
Intended use [
12] ).
3. Connecting the interface's terminals for status information
a Connect the terminals (SIo0 ... SIo3) to a control system that supports the evalu­
ation of status information.
4. Configure communication mode for downloading the Key ID number
a To download the Key ID number in handshake­controlled communication mode,
connect terminals IDo3 and IDi1 of the Key ID interface.
No configuration is required for transmitter­controlled communication mode.
5. Connecting the terminals of the Key ID interface
a Depending on the selected communication mode, connect the terminals of the Key
ID interface to a control system that supports the download of the Key ID number.
or
a Connect IDo0 to a control system, if all you wish to do in handshake­controlled
communication mode is evaluate whether the transponder key is valid/invalid. In
this case you will only use IDo0 as a signal output. The unused terminals on the
Key ID interface (IDo1, IDo2 and IDi0) may remain unwired ("open").
