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.
The document contains fundamental safety information that
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.

3.2 Description
The GEMÜ 4240 combi switchbox is suitable for mounting to
pneumatically operated linear actuators. The position of the
valve spindle is reliably detected electronically and reported
via microswitches or proximity switches, using play-free and
non-positive mounting. Integrated pilot valves enable direct
activation of the process valve connected to them. The
product has been designed specially for valves with a stroke
of 5 to 75 mm.
3.3 Function
The GEMÜ 4240 combi switchbox indicates the current posi-
tion of the valve. When the valve is opened, the spindle in the
combi switchbox moves upwards and indicates that the valve
is OPEN using the communication interface. When the valve is
closed, the spring in the mounting kit presses the spindle in
the combi switchbox downwards and indicates that the valve
is CLOSED using the communication interface.

Order variant
In the corresponding design with CONEXO, this product has
an RFID chip (1) for electronic identification purposes. The po-
sition of the RFID chip can be seen below. The CONEXO pen
helps read out information stored in the RFID chips. The CON-
EXO app or CONEXO portal is required to display this informa-
tion.

For further information please read the operating instructions
for CONEXO products or the CONEXO datasheet.
Products such as the CONEXO app, the CONEXO portal and
the CONEXO pen are not included in the scope of delivery and
need to be ordered separately.
5 Correct use
DANGER
Danger of explosion!
▶Risk 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 not intended for use in potentially explosive
areas.
The product is designed for mounting to pneumatically oper-
ated linear actuators. The position of the valve spindle is elec-
tronically detected and reported via microswitches or proxim-
ity switches through play-free and non-positive mounting. In-
tegrated pilot valves enable direct activation of the process
valve connected to them.
●Use the product in accordance with the technical data.

6 Order data
The order data provide an overview of standard configurations.
Please check the availability before ordering. Other configurations available on request.
Note: A valve specific mounting kit is required for assembly. For designing the mounting kit, the valve type, nominal size, control
function and actuator size must be stated.

- Push in the spindle until it pushes against the spring and
then slowly release the pressure on the spring.
NOTICE
▶For some valves (e.g. GEMÜ 650 and GEMÜ 687) it is ne-
cessary to fit a pressure disc between the threaded ad-
apter and the actuator head. This is included in the re-
quired mounting kits, sometimes with an additional O-ring
(only GEMÜ 650 with normally open and double-acting
control function – code 2+3).
▶If the pressure disc does not have a groove for a seal, this
will already be inserted in the groove provided at the ad-
apter opening of the actuator head (e.g. GEMÜ 687 with
normally open control function – code 2).

Insert the O-ring 11 (if in-
cluded) into the corresponding
groove on the adapter 6.
If included: Push the pressure
disc 9 over the adapter 6 and
insert the O-ring 10 in the in-
tended groove of the pressure
disc.
10.4 Threaded adapter assembly (linear actuator)
With some mounting kits, it is necessary to install a threaded
adapter as well. This threaded adapter is enclosed with the re-
quired mounting kits. Valves with a normally open and double
acting control function (code 2+3) also include additional O-
rings (1+2).
