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.

Description
The GEMÜ 549 eSyDrive is a motorized 2/2-way angle seat
globe valve with a hollow shaft electric actuator. The eSyDrive
hollow shaft actuator can be operated as On/Off or with integ-
rated positioner or process controller. The valve spindle is
sealed by a self-adjusting gland packing providing low-main-
tenance and reliable valve spindle sealing even after a long
service life. A wiper ring fitted in front of the gland packing
protects the seal against contamination and damage. An in-
tegral optical and electrical position indicator is standard.
3.4 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.

3.5 Correct use
DANGER
Danger of explosion!
▶GRisk of death or severe injury.
●Do not use the product in potentially
explosive zones.
WARNING
Improper use of the product
▶Risk of severe injury or death.
▶Manufacturer liability and guarantee will be void.
●Only use the product in accordance with the operating
conditions specified in the contract documentation and in
this document.
The product is designed for installation in piping systems and
for controlling a working medium.
The product is not intended for use in potentially explosive
areas.
●Use the product in accordance with the technical data.
3.6 Product label
The product label is located on the actuator. Product label
data (example):
Design in accordance with order data
Device-specific data
Year of manufacture
Item number Traceability number Consecutive number
- XXXXXXXX|YYYY
The month of manufacture is encoded in the traceability num-
ber and can be obtained from GEMÜ. The product was manu-
factured in Germany.
The operating pressure stated on the product label applies to
a media temperature of 20 °C. The product can be used up to
the maximum stated media temperature. You can find the
pressure/temperature correlation in the technical data.
4 GEMÜ CONEXO
The interaction of valve components that are equipped with
RFID chips and an associated IT infrastructure actively in-
crease process reliability.
Thanks to serialization, every valve and every relevant valve
component such as the body, actuator or diaphragm, and
even automation components, can be clearly traced and read
using the CONEXO pen RFID reader. The CONEXO app, which
can be installed on mobile devices, not only facilitates and im-
proves the "installation qualification" process, but also makes
the maintenance process much more transparent and easier
to document. The app actively guides the maintenance techni-
cian through the maintenance schedule and directly provides
him with all the information assigned to the valve, such as
test reports, testing documentation and maintenance histor-
ies. The CONEXO portal acts as a central element, helping to
collect, manage and process all data.

Interface: Ethernet
Function: Parameterisation via web browser
IP address: 192.168.2.1 alterable via web browser
Subnet screen: 255.255.252.0 alterable via web browser
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.

6.7.7 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).
