1 Quick commissioning
CAUTION
Hazardous situation
▶ Risk of injury or damage possible.
● For correct commissioning, the product must be calibrated to the process valve via
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
Incorrect initialization
● Always carry out initialization without operating medium pressure on the process valve. Carry out initialization of the pro-
cess valve in neutral position (NO/NC).
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 default 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).
NOTICE
Operating errors
● Prior to commissioning, familiarize yourself with the operation of the product.
The initialization is absolutely essential for the correct operation of the positioner and must be carried out once.
For delivery of the product pre-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 - the positioner is in automatic operation. A reinitialization is recom-
mended 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 actuator replacement).
The initialization is retained even in the event of voltage cutoff.
Prerequisites:
- Mounted to the valve.
- Air supply, max. 7 bar, connected.
- 24 V DC supply voltage connected.
- Set value and actual value signals need not be connected.
- For correct commissioning proceed as described in the following flow chart:
NOTICE
Tip for use
▶ During automatic initialization of actuators whose movement profiles are not continuous (i.e. with undefined stopping or
stalling, e.g. with large size butterfly valves), it may not be possible to clearly detect the end positions and unjustified error
messages may appear (for example LEAKAGE).
▶ Manual initialization with sequential movement through the menu by the operator or, if possible, acknowledging the error
message to repeat the step may help here (see “Manual initialization“, page32).
