5.2.1
Connecting meters
For the purpose of measuring consumption the pulse transducers from up
to four meters can be connected to the DE1 to DE4 digital inputs of the
DL230. Alternatively, encoders can be connected to inputs DE1 and DE2.
III. 8
Further details and special features
regarding the use of the pulse
transducer and encoder are
described in the following sub-
chapters.
The wire cross-section for the connection to the DL230
inputs is 0.3 … 2.5 mm
2
.
When using stranded wire, use appropriate wire ferrules.
Use only cables, which fit to the cable glands in order to
keep IP protection class also after the installation.
Minimum cable diameter:
Cable gland
M12 ≥ 5 mm
Cable gland
M16 ≥ 5,5 mm.
5.2.1.1 Connection to a pulse transducer
1. Connect the meter's pulse transducers to the DE1 to DE4 terminals (III.
8) of the DL230. The polarity can be freely selected (the symbols "+"
and "-" on the terminals are used for the connection of other pulse
transducers or encoders).
2. Adjust the measurement parameters, e.g. the cp value (pulse constant),
as described in chapter 5.3.1.2.
5.2.1.2 Connection to an encoder
1. Connect the meter's encoder(s) to the DE1 and DE2 terminals (III. 8) of
the DL230.
The polarity should be taken into consideration, i.e. connect the "+" of
the encoder to the "DE1 +" terminal and "-" to the "DE1 -" terminal
respectively.
2. Adjust the measurement parameters, e.g. the encoder type, as de-
scribed in chapter 5.3.1.3.
