2 Safety information
The safety information in this document refers only to an indi-
vidual product. Potentially dangerous conditions can arise in
combination with other plant components, which need to be
considered on the basis of a risk analysis. The operator is re-
sponsible for the production of the risk analysis and for com-
pliance with the resulting precautionary measures and re-
gional safety regulations.

must be observed during commissioning, operation and main-
tenance. Non-compliance with these instructions may cause:
- Personal hazard due to electrical, mechanical and chemical
effects.
- Hazard to nearby equipment.
- Failure of important functions.
- Hazard to the environment due to the leakage of dangerous
substances.
The safety information does not take into account:
- Unexpected incidents and events, which may occur during
installation, operation and maintenance.
- Local safety regulations which must be adhered to by the
operator and by any additional installation personnel.
Prior to commissioning:
1. Transport and store the product correctly.
2. Do not paint the bolts and plastic parts of the product.
3. Carry out installation and commissioning using trained
personnel.
4. Provide adequate training for installation and operating
personnel.
5. Ensure that the contents of the document have been fully
understood by the responsible personnel.
6. Define the areas of responsibility.
7. Observe the safety data sheets.
8. Observe the safety regulations for the media used.
During operation:
9. Keep this document available at the place of use.
10. Observe the safety information.
11. Operate the product in accordance with this document.
12. Operate the product in accordance with the specifications.
13. Maintain the product correctly.
14. Do not carry out any maintenance work and repairs not de-
scribed in this document without consulting the manufac-
turer first.

3.2 Description
The GEMÜ 649 diaphragm valve is actuated by a motorized
hollow shaft actuator. It is based on technology that does not
use brushes or sensors and therefore guarantees high per-
formance and a long service life. In addition to open/close ap-
plications, the valve is ideal for variable and complex control
applications. The actuator has an integrated web server for
parameterization and diagnostics purposes.
3.3 Function
The product controls or regulates (depending on version) a
flowing medium by being closed or opened by a motorized ac-
tuator.
The product has an optical position indicator as standard. The
optical position indicator indicates the OPEN and CLOSED po-
sitions.

5 GEMÜ CONEXO
Order without CONEXO
If you have ordered the product without CONEXO functionality,
the RFID chip is used for traceability in the production process
and quality assurance. Expansion to include the CONEXO
functionality at a later date must be coordinated with GEMÜ.
Order with CONEXO
GEMÜ CONEXO must be ordered separately with the ordering
option "CONEXO" (see order data).
For electronic identification purposes, each replaceable com-
ponent contained in the product you have purchased is
equipped with an RFID chip (1). Where you can find the RFID
chip differs from product to product.

The CONEXO pen helps read out information stored in these
RFID chips. The CONEXO app or CONEXO portal is required to
view this information.
6 Reading out the RFID transponder
1. Press the On/Off key 4 on the CONEXO pen.
ðThe CONEXO pen has been switched on.
ðLED 1 flashes.
2. Connect the CONEXO pen to the tablet.
üThe user finds themselves in a menu within the CONEXO
app where a scanning operation is requested.
3. Hold the CONEXO pen directly against the RFID chip of a
component or functional location and press the scan key
8.
ðIf an RFID chip has been scanned correctly, the LED 7
turns green.
ðIf an RFID chip has not been scanned correctly, the LED 5
turns red.
ðAn audible signal is emitted during a correct scan process.
ðThe data that is read out is transferred to the CONEXO
app.
4. Scan as many components as required.
5. Hold down the On/Off key 4 for at least three seconds.

The sterilization temperature is only valid for steam (saturated steam) or superheated water.
If the sterilization temperatures listed above are applied to the EPDM diaphragms for longer periods of time, the
service life of the diaphragms will be reduced. In these cases, maintenance cycles must be adapted accord-
ingly.
PTFE diaphragms can also be used as moisture barriers; however, this will reduce their service life. This also ap-
plies to PTFE diaphragms exposed to high temperature fluctuations. The maintenance cycles must be adapted
accordingly. GEMÜ 555 and 505 globe valves are particularly suitable for use in the area of steam generation
and distribution. The following valve arrangement for interfaces between steam pipes and process pipes has
proven itself over time: A globe valve for shutting off steam pipes and a diaphragm valve as an interface to the
process pipes.

All pressures are gauge pressures. Operating pressure values were determined with static operating pressure
applied on one side of a closed valve. Sealing at the valve seat and atmospheric sealing is ensured for the given
values.
Information on operating pressures applied on both sides and for high purity media on request.

MG = diaphragm size
Kv values in m³/h
Kv values determined in accordance with DIN EN 60534 standard, inlet pressure 5 bar, Δp 1 bar, stainless steel
valve body and soft elastomer diaphragm. The Kv values for other product configurations (e.g. other diaphragm
or body materials) may differ. In general, all diaphragms are subject to the influences of pressure, temperature,
the process and their tightening torques. Therefore the Kv values may exceed the tolerance limits of the stand-
ard.
The Kv value curve (Kv value dependent on valve stroke) can vary depending on the diaphragm material and dur-
ation of use.

The actuator and the PC must be in the same network to use the web server. The IP address of the actuator is entered in the
web browser and the actuator can then be parametrised. In order to use more than one actuator, a definitive IP address must be
assigned to each actuator in the same network.

8.7.7 Behaviour in the event of an error
Function: In the event of an error the valve moves to the error position.
Notes: Moving to the error position is only possible with full power supply. This behaviour is not a
safety position. The valve must be operated with a GEMÜ 1571 emergency power supply module
(see accessories) to ensure the function in case of voltage loss.
Error position: Closed, open or hold (adjustable via eSy-web web interface).
