4.1 Introduction
4.2 General
The S251B Reader has been designed with easy installation in mind. The following
information provides you with any details such as switch settings and so on that you
will need to know.
4.3 Mechanical Mounting
a. If you are mounting the reader on a DIN rail TS35, clip the reader into the bot-
tom of the rail and then snap it into the top.
or
b. If you are mounting the reader onto a wall where there is
No
vibration, snap in
the four mounting adapters and screw the reader to the wall using M4 screws.
or
c. If you are mounting it onto a wall where it may be subject to vibration, open the
reader, drill thru the marked mounting holes and screw the reader to the wall
using M4 screws and the appropriate washers.
4.3.1 Power Supply
Connect a Regulated dc power supply (between 10 and 24 V providing a minimum
of 2A) to the reader - the polarity of the connection is shown on the front panel of the
reader.
Set the Power Range Setting wire bridge to match your input voltage (see Table 2).
We recommend that you use a linear power supply. If this is not possible and you
wish to use a switched mode power supply, DO NOT use one that operates below
200 kHz. (switched mode power supplies that operate below 200 kHz. might interfere
with transponder signals and thus reduce the reading range).
Note:
Always ensure that the reader is switched off when making or break-
ing connections to it.
