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.

The User manual for actuator commissioning and integration into a fieldbus system.

You can also download these documents at http://www.siko-global.com/p/ap20.

Additional information and guidance regarding this device can also be found there.

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). Individual bits of larger logic units are named with their value after a

dot (e. g., CW.9; control word bit 9).

1.3 Intended use

For the further functional description, normal operation of the system with unchanged factory

setting is assumed unless otherwise described.

The present device is an absolute position indicator with integrated Industrial Ethernet

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

target value can be displayed below the actual value 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 Target Window parameter). The indicator direction

indicates in which direction the sensor must be moved to reach the target window. In

addition, the position status of two two-color LEDs (green and red) is displayed. Device

malfunctions or inadmissible operating states are recorded in an error memory.

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

in a non-volatile memory to the application. 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 AP20 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 AP20 works with the last saved parameters.

Unless a fault has been detected, the AP20 starts normal operation.

2Display and control keys

2.1 General

Fig. 1: Display and control elements

2.2 LCD display

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

range are displayed with "FULL".

The actual value is displayed in the first line and "----" in the second line. The target value

can be declared valid by means of CW.9 = 1 and displayed in the second line. If necessary, a

direction indicator (arrow) is also displayed.

The battery status is indicated by the battery symbol . If battery voltage Target value

acknowledgment mode critical value, the battery symbol on the display will flash. If the value

falls below a minimum value or if the battery is missing, the symbol lights permanently.

With incremental measurement function activated, the incremental measurement symbol

is shown.

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

2.2.1 Extended display range

Values up to -199999 can be displayed by means of the control word. 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, "FULL" will be displayed.

2.3 LED display

2.3.1 Positioning status

A test sequence is executed on these LEDs during initialization.

When the target value is displayed, the LED1, LED2 inform about a deviation between the

actual value and the target window. The function of positioning status LEDs can be

configured.

2.3.1.1 Device status LED1, LED2

LED states valid at factory setting.

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

be activated by means of parameters.
