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 AZL5…, 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» be-
low.
To make the addressing, the following menu is required on the AZL5…:
«Params & Display»
Æ
«Actuators»
Æ
«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 AZL5… 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 AZL5…
does not allow double assignments. In that case, a display tells the user that an appro-
priate actuator is already used by the system.
