The user can return to the next higher menu level by pressing ESC.
To make the addressing, the actuator must be opened. A button and an LED are located
behind the actuator's removable plastic cover.
In connection with addressing with the help of the AZL51..., the button is used to define
the address of an actuator.
When commissioning the plant, the actuators are in their addressing mode.
To indicate this, the LED is steady on. If the LED is not steady on, refer to «Reset»
below.
To make the addressing, the following menu is required on the AZL51...:
«Params & Display» à «Actuators» à «Addressing»
This menu contains the choice of actuators to be addressed (e.g. the air actuator). By
appropriately positioning the pointer and then pressing ENTER, the user can select the
required actuator function.
Address assignment is started by pressing ENTER. After a short period of time, the user
will be prompted to press the button on the actuator to be addressed.
The AZL51... confirms the successful address assignment. To be sure, the address of
the actuator can be checked against the blink code which now appears.
This procedure can be repeated for other actuators used by the system, but the
AZL51... does not allow double assignments. In that case, a display tells the user that
an appropriate actuator is already used by the system.
