Operational status indication

unaddressed actuator
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»
«Actuators»
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.
To select the direction of rotation, choose the following menu on the AZL5...:
«Params & Display»
«Actuators»
You are given the choice of «Standard» and «Reversed»:
Standard (counterclockwise)
0°
90°
Facing the end of the drive shaft ( not mounted)
To check the direction of rotation, every actuator can be moved in the home position in
fault-free standby mode.
The parameter is filed in the basic unit so that the direction of rotation need not be reen-
tered when replacing the actuator.
Note:
After setting the ignition positions or curves, the direction of rotation can
only be changed after deleting the curves and ignition positions on setting
menu «Delete Curves».
This facility makes it possible to reset an already addressed actuator in the case of a re-
placement, repair, or if addressing is wrong (wrong address assignment by the user).
For that purpose, the user must press the actuator's addressing button for at least 10
seconds when the actuator is in normal operation. The actuator will then reset its ad-
dress which is indicated by the LED when steady on.
