Elster/Honeywell.
This product is not intended to be used for installation on/in (gas) meters
from other manufacturers.
1.8 Legal declarations
The metrological conformity assessment is based on the regulations of the
country concerned, where the device will be used.
1.9 Recycling and environmental protection
Honeywell has designed the transport packaging of the device to be
environmentally friendly. Packaging materials are always selected
consistently with a view to recycling. The cardboard items used constitute
secondary raw materials for the paperboard and paper industry. The
Instapak® foam packaging is recyclable and can be reused.
Plastic sheeting and strips/bands are also made of recyclable plastic. At
Honeywell, subsequent recycling and disposal are already elements of the
product development process. When selecting the materials, we allow for
reusability of the materials, suitability of materials and subassemblies for
dismantling and separation, and the risks of environmental pollution and
health risks when recycling and dumping on landfill sites.

2. Structure and function
The ENCODER S1/S1D products are opto-electronic read-out units with
digital data transfer for turbine and rotary gas meters from Elster/Honeywell.
2.1 Device description
The encoder is integrated in an Elster/Honeywell meter index. The
technology is based on opto-electronic scanning which identifies the
position of the individual rollers on the mechanical index in a contact-free
process. The reading process for the Absolute ENCODER is therefore
identical to the manual reading of the mechanical index on site. Operation
of the Absolute ENCODER requires neither a battery nor an individual power
supply, as the power required for reading is supplied by the connected
device. The described technology can be flexibly adjusted to the application
by choosing one of the optional interface types.
2.2 Working principle
The digit rollers of the mechanical index are individually scanned by opto-
electronic means. Each roller has three asymmetrically arranged slots of
different lengths which are then scanned by five beams of light to determine
their position. The respective position of the roller and thus the digits on the
roller can be clearly identified thanks to the specific arrangement of the slots.
The light barriers consist of phototransistors, LEDs and optical waveguides
which are all scanned and evaluated one after the other using time-series
analysis. Control and evaluation of the light barriers is carried out by a
controller. This exactly defines the position of each individual digit roller and
transmits it to the connected add-on device (e.g. volume conversion device,
data logger or bus system) as part of a defined protocol. Depending on the
interface type, the protocol already includes various meter data such as the
factory number and meter size. The plug-and-play system means that no
subsequent parameterization is required.

2.3 Versions
The ENCODER is available in two different mechanical versions, S1 and
S1D:
Fig. 1 | ENCODER S1 and ENCODER S1D
The ENCODER is available with the following communications protocols:
NAMUR (Ex Zone 1 or 2)
Unidirectional serial interface for direct connection to volume
conversion devices and data loggers (levels comply with EN 60947-5-5).
SCR+ (Ex Zone 1 or 2)
Low power interface, widely used for water meters, uses a protocol which
complies with IEC 62056-21 (formerly IEC 1107). The SCR interface can
be made compatible with the CL interface using a small separate,
external circuit.
M-Bus (without explosion protection)
For correcting multiple meters to an electronic evaluation system, e.g. in
industry or in a residential environment.
2.4 Connection configurations
Use only a screened cable to connect the encoder and ensure that the
pin assignment is correct (see Fig. 2 and sticker next to the cover of the
terminal box).
Only connect one conductor per terminal.
The maximum wire cross-section is 2.5 mm².
Wire end ferrules must be used for flexible cables.

English
Tighten the screw terminals with a tightening torque of at least 0.8 Nm
to maximum 1 Nm.
Ensure the correct polarity of the two-wire connection on the Namur
interface. The M-Bus and SCR/SCR+ interfaces are independent of the
polarity.
It is possible to apply screening and to run a cable to the meter housing
or the pipe. It must be checked in advance that the grounding system
used allows grounding on both sides (ground loops and potential
difference in grounding).
Fig. 2 | Terminal assignment
On the version with a double index, the lower 2 terminals determine the
direction of the gas flow:
Bridge attached to lower terminals (as delivered): upper index is activated:
Fig. 3 | Flow direction right > left
Lower terminals unassigned: lower index is activated:
Fig. 4 | Flow direction left > right
An IN-Sxx pulse generator may be installed on the encoder index cover
as an option. The installation work and connection configuration are
shown in the relevant instruction manual.

2.5 Top-mounted ENCODER
The top-mounted version of the
ENCODER S1/S1D is suitable for the
mechanical index drive of the MI2 index
cover and can be operated in addition to
the mechanical index installed in the gas
meter.
Connect the connector of the top-
mounted unit to the mechanical index
drive of the driving unit.
Use a locking screw to prevent it from
being pulled out.
Secure the locking screw with a seal for
use in custody transfer applications.
The electrical connection is made as
described in section 2.4 Connection
configurations.
3. Installation and commissioning
The encoder is supplied fully parameterized and ready for operation
together with the gas meters.
The electrical connection is made as described in section 2.4
Connection configurations.
For connecting the devices, use a screened cable pursuant to
IEC EN 60079-14.
WARNING!
If the encoder is used in hazardous areas, it must be connected to
an intrinsically safe circuit.
For installations in Zone 1, safety barriers or supply units must be
certified pursuant to ignition protection rating Ex ib IIC or Ex ia IIC.
