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:
ð Supply the connector 1 with pneumatic control air supply (max. 8/10 bar).
ð Connect the connector 2 to the control air connector of the process valve.
3. Connect the product electrically:
ð Connect 24 V DC supply voltage – pin 1: +24 V; pin 3: GND (LED POWER lights up, LED OPEN, ERROR, CLOSED flash) ¹⁾.
ð Connect set value signal – pin 2: Iw+/Uw+; pin 3: GND (Iw-/Uw-) ²⁾.
4. Start automatic initialisation (speed-
AP
function):
ð Briefly activate 24 V DC initialisation impulse (t> 100 ms) on pin 5 (LED OPEN/CLOSED flash alternately) and deactivate
it again
3)
.
ð The 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.
