Quick commissioning
CAUTION
Hazardous situation
▶Risk of injury or damage possible.
●For correct commissioning, the product must be calibrated to the process valve by
means of the initialization process.
●During this commissioning, the valve is automatically opened and closed several
times. It must therefore be ensured in advance that this does not lead to a dangerous
situation.
NOTICE
Operating errors
●Prior to commissioning, familiarize yourself with operation of the product.
NOTICE
Incorrect initialization
●Always carry out initialization without operating medium pressure on the process valve
NOTICE
●For delivery of the product assembled on a valve at the factory, the complete construction is already ready for operation at
a control pressure of 5.5 to 6 bar without operating pressure. A reinitialization is recommended if the plant is operated with
a different control pressure or if the mechanical end positions have been changed (e.g. seal replacement on the valve or ac-
tuator replacement). The initialization is retained even in the event of voltage cutoff.
NOTICE
●For delivery of the product without factory setting (e.g. for delivery without valve) initialization must be carried out once for
correct operation. This initialization must be repeated every time that the process valve is changed (e.g. seal replacement
or actuator replacement).
1. Mount the product on the process valve mechanically using the mounting kit.
2. Connect the product pneumatically:
ðSupply the connector 1 with pneumatic control air supply (max. 8/10 bar).
ðConnect the connector 2 to the control air connector of the process valve.
3. Connect the product electrically:
ðConnect 24 V DC supply voltage – pin 1: +24 V; pin 3: GND (LED POWER lights up, LED OPEN, ERROR, CLOSED flash) ¹⁾.
ðConnect set value signal – pin 2: Iw+/Uw+; pin 3: GND (Iw-/Uw-) ²⁾.
4. Start automatic initialisation (speed-AP function):
ðBriefly activate 24 V DC initialisation impulse (t> 100 ms) on pin 5 (LED OPEN/CLOSED flash alternately) and deactivate
it again 3).
ðThe initialisation phase lasts a few minutes, during which the process valve is opened and closed several times. The ini-
tialisation process is ended automatically.
5. The product is ready for operation and responds to an externally specified set value signal.
¹⁾ Provided that an initialisation has not been previously carried out, otherwise deviating operating status display.
²⁾ Set value signal is not required for initialisation and can optionally be connected later.
3) If the input has not been wired on the system side, the separately obtained initialisation kit 1434 000 ZIK can be used for this.
Alternatively, for connectors without cable, the housing of the M12 connector, with which the product has been connected, can
be opened and a temporary wire bridge can be attached from pin 1 to pin 5.

3.3 Description
The GEMÜ 1434 μPos digital electro-pneumatic positioner is
used to control small to medium nominal size process valves
with single acting linear actuators. The solid compact housing
has a transparent cover. LEDs for status indication are integ-
rated. Due to factory preconfiguration, this product does not
require a display with operating keys. Pneumatic and elec-
trical connections are arranged so as to save space and en-
able easy access. All these features make the GEMÜ 1434
μPos a cost-effective solution for control valves with basic re-
quirements.
3.4 Function
The GEMÜ 1434 µPos digital electro-pneumatic positioner is
an intelligent digital positioner designed for mounting to pneu-
matic actuators. The product is directly mounted to the actu-
ator as standard. The travel sensor is already integrated in the
positioner.
Optionally, the product can be ordered for an external mount-
ing type, in which a separate travel sensor is connected using
an M12 connector.
The travel sensor measures the current position of the valve
and reports it to the electronic system of the product. The
electronic system then compares the actual value of the valve
with the set value specified and readjusts the valve accord-
ingly in the event of a control error.
The optional actual value output provides the valve position
currently determined (in same direction according to rule dia-
gram) as an analogue value.
For correct operation, the positioner must first be calibrated
(initialised) to the connected process valve. This is carried out
using the automatic initialisation function, which can be activ-
ated by a momentary voltage pulse at the programming input.
Once this has been carried out, the positioner automatically
switches to the normal operating mode and responds to the
specified external set value signal.

5 Correct use
DANGER
Danger of explosion
▶Risk of severe injury or death.
●Do not use the product in potentially
explosive zones.
●The product can control valves in po-
tentially explosive areas using special
wiring (installation of the positioner
outside the EX area).
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 with integrated pilot valves is designed for linear
actuators, has a microprocessor-controlled intelligent position
control as well as an analogue travel sensor system (poten-
tiometer) and is connected in a force-locking way with the ac-
tuator spindle by means of a mounting kit (spring, operating
bush). The valve position and the integrated travel sensor can
be monitored via the electrical connections. The pneumatic
actuator is directly operated and controlled by means of the
pilot valves.
