1General Information

1.1 Documentation

The following documents are associated with this document:

•The data sheet describes the technical data, the dimensions, the pin assignment, the

accessories and the order key.

•The installation instructions describe the mechanical and electrical installation with all

safety-relevant conditions and the associated technical specifications.

•User manual for connecting the display to an IO-Link master and for commissioning.

•IODD file (IO-Link Device Description); with the help of this file, the connection and

configuration with an IO-Link master is possible by means of commercially available IO-

Link masters and their configurators.

1.2 Definitions

If not explicitly stated otherwise, decimal values are given as figures without an extension (e.

g., 1234), binary values are marked after the figure with a "b" (e. g., 1011b), hexadecimal

values with an "h" (e. g., 280h).

1.3 Intended use

Unless otherwise described normal operation of the system with unchanged factory setting is

assumed for the further description of functions.

The present device is an absolute position indicator with integrated IO-Link interface and a

hollow shaft for direct shaft mounting. Indicators, control buttons and interface are only

active with external power supply. The sensor of measurement encoder works magnetically

incrementally. Without an external power supply, encoder changes are recorded with battery

support. The status of the replaceable battery is monitored. A volatile TargetValue can be

displayed below the ActualValue via the backlit two-line LC display A direction display

(indicator) is displayed if there is a deviation between the actual value and the target window

(target value including TargetWindow parameter). The arrow direction indicates in which

direction the shaft must be rotated to reach the target window. In addition, different

visualization tasks can be realized with the help of two two-color LEDs (green and red). Device

malfunctions or inadmissible operating conditions are displayed.

Display and control elements

The 3 buttons can be used to select various functions and to adapt the device parameters of

the application stored in non-volatile memory. The actual value can be queried via the

interface, the target value can be changed and all device parameters can be adjusted.

1.4 Switching on the operating voltage

The AP05 will be initialized after switching on the supply voltage. A system and display test is

executed during initialization, the LEDs are lighted consecutively and the parameters are

loaded from the non-volatile memory into the RAM of the controller.

At first use, the default values are used during initialization. After the return of the external

power supply or software reset (warm start), the AP05 works with the last saved parameters.

If no fault has been detected, the AP05 starts normal operation and can communicate with an

IO-Link Master.

2Display and control elements

The position indicator has a two-line display with special characters and three control keys.

The actuator can be configured and controlled via the keys.

Two device status LEDs (LED1, LED2) serve for monitoring positioning.

A COM LED (COM LED) indicates the status of the IO-Link communication.

Fig. 1: Display and control elements

2.1 LCD display

The display range is limited to -199999 … 999999. Values outside this

range are displayed with "".

When the operating voltage is applied, the actual value (absolute position value, ActualValue)

is displayed in the first line. If there is no valid target value "  ". appears in the second

line. If a target value is declared valid by means of the control bit in the process data (see e.

g., bc09_TargetValueActive), this is displayed in the 2nd line. The values displayed are

determined by the operating mode.

Direction indicators (arrows) support positioning.

The battery symbol is shown with a critical or insufficient battery status. If battery

voltage drops to a critical value, the battery symbol on the display will flash. If it falls below

the minimum value, the symbol will glow permanently.

With incremental measurement function activated, the incremental measurement symbol

is shown.

This is signaled in red letters in the event of a fault.

Fig. 2: Two-line 7 segment LCD display

2.1.1 Extended display range

Values up to -199999 can be displayed by means of the ControlWords (see

bc03_DisplayRange). If the relevant bit has been set and the value to be displayed is between

-199999 and -999999, then the negative sign and the digit of the highest order will flash

alternately. If the value range drops below -999999, "" will be displayed.

2.2 LED display

2.2.1 Device status

A test sequence is executed on these LEDs during initialization.

In its basic state (factory setting) the LED display has different meanings depending on the

operating mode (see chapter 3.1).

In order for LED1 or LED2 to be controlled via the ControlWord, this function of the LEDs must

be activated by means of parameters (see chapter 3.1.1.3, 3.1.2.1, 4.4 and 5.1).

2.3 Control keys

Pressing the Incremental button switches the increment function or a relative

measurement on or off.

Pressing the Calibration button starts the calibration (see chapter 3.4) and acknowledges

an existing fault (see chapter 3.6).

In the "Alphanumeric display" operating mode, the receipt of a target value is acknowledged

by this action.

Pressing the Configuration button starts the parameterization.
