manufacturer. The manufacturer strives to always respect the copyright of

others or to use his own or licence-free works.

We would like to point out that data transfer via the Internet (e.g. through e-

mail communication) can be subject to breaches in security. It is not

possible to provide complete protection against access by third parties.

1.4 Exemption from liability

The manufacturer shall not be liable for damage of any type caused by the

This exemption from liability does not apply if the manufacturer has acted

intentionally or with gross negligence. In the event that any applicable law

does not allow such restrictions on implied warranties for defects, or the

exclusion or limitation of certain payments for damages, and should such

law apply to you, the above-mentioned exemption from liability, exclusions

or limitations may not apply to you in part or in whole.

For every product purchased, the warranty is valid in accordance with the

corresponding product documentation as well as the conditions of sale and

delivery of the manufacturer.

1.5 Product liability and guarantee

The responsibility as to whether the device is suitable for the intended use is

that of the operator. The manufacturer cannot accept any liability for the

consequences of misuse by the operator. Improper installation or operation

of the devices (systems) render the warranty void. Furthermore, the relevant

“General Terms and Conditions” which form the basis of the purchase

contract also apply.

1.6 Personnel

This manual is aimed at staff who have adequate specialist and technical

knowledge (in Germany, for instance, in accordance with DVGW Codes of

Practice 492 and 495 or comparable technical regulations) on the basis of

their training and experience in the sector of energy and gas distribution.

1.7 Intended use and field of application

This product is intended to be used for the installation on/in gas meters from

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.

TRZ with ENCODER S1 RABO with ENCODER S1D

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.
