• special features AC2566: stainless steel screws, Viton sealing Installation / Addressing When you use module lower parts without addressing socket (AC5000 or AC5003) first address the module by placing it onto an addressing unit (AC1144) and assign a free address between 1 and 31. When you use module lower parts with an addressing socket (AC5010 or AC5011) the modules can be addressed with the addressing adapter E70213 later on. Mount the module onto the wired module lower part of the AS-i net- work, tightening torque 0.8 Nm. As an alternative FC/FC-E lower parts with earthing lead (AC5020...AC5023) can be used to increase the noise immunity. 10Electrical connection The analogue module is connected to the AS-Interface via the stan- dardised EMS (supply from AS-i) or the E-EMS (supply from an ext. 24 V PELV voltage source). If the supply is to be from an external 24 V source, a FC-E lower part (art. no. AC5003 or AC5011) must be used. If a total of over 100 mA is needed for the sensor supply, the supply must be from an external 24 V PELV voltage source. The supply is automatically changed when the external 24 V vol- tage is supplied.

To do so, set the combined sensor accordingly (e.g. by selection of a switch point which cannot be reached or by the configuration "NPN switching"). Current measurement AC2516, AC2566 For all the following wiring diagrams the indicated pin connection refers to the analogue module. When an external link between pin 3 and pin 4 is used, the internal link can be deactivated by resetting the parameter bit P0! The internal link (pin 3 and pin 4) must be activated via the para- meter bit P0. Connection of a 2-wire sensor without own supply Connection of a 2-wire sensor with own supply

U-Operation AC2516, AC2566 Check whether the unit operates correctly. Display by LEDs:

• LEDs yellow AI-1...AI-4 on: analogue signal in the measuring range

• LEDs yellow AI-1...AI-4 flashing: analogue signal outside the measuring range, no sensor connected or wire break

• LEDs yellow AI-2...AI-4 out: no sensor connected (at least one LED flashes because not all chan- nels can be deactivated via the parameter bit P1/P2 (channel activa- tion, channel 1 is always activated)

• LED red FAULT flashes: periphery fault*

• Periphery fault A periphery fault is displayed:

• if at least one of the analogue signals is outside the value range

• if nothing is connected to at least one analogue channel although the respective channel is activated

• if a wire break occurred Operation AC2517 Check whether the unit operates correctly. Display by LEDs:

• LEDs yellow AI-1...AI-4 on: respective channel is activated analogue signal in the measuring range or no sensor connected (it cannot be differentiated whether the 0 V signal is applied or whether no sensor is connected) (channel 1 is always activated)

• LEDs yellow AI-1...AI-4 flashing: analogue signal outside the measuring range (outside range) 15• LEDs yellow AI-2...AI-4 out: respective channel is not activated

• LED red FAULT flashes: periphery fault*

• Periphery fault A periphery fault is displayed:

• if at least one of the analogue signals is outside the value range Measuring range of the analogue input modules The measuring ranges, the states of the LEDs and their meaning are indicated in the following tables: Analogue input module 4 ... 20 mA - AC2516, AC2566

23 mA 20001 ... 23000 4E21 ... 59D8 on above nominal range > 23 mA 32767 7FFF flashes outside rangeAnalogue input module 0 ... 10 V - AC2517 Transmission time of the analogue values The transmission time of the analogue values depends on the conver- sion time of the analogue signals into digital signals in the AS-i modu- le and on the transmission time via the AS-Interface. Example: Transmission time of 2 analogue channels The conversion time for 2 analogue input signals into digital signals is 120 ms. The transmission time of the 2 16-bit values via the AS-inter- face ideally is 7 AS-i cycles per value. For a cycle time of 5 ms per ASi cycle this results in a transmission time of 2 x 7 x 5 ms = 70 ms via the AS-Interface. Thus the total transmission time for 2 analogue values ideally is 120 ms (conversion time) + 70 ms (transmission time) = 190 ms. Example: Transmission time of 4 analogue channels The conversion time for 4 analogue input signals into digital signals is 240 ms. The transmission time of the 4 16-bit values via the AS-inter- face ideally is 7 AS-i cycles per value. For a cycle time of 5 ms per AS-i cycle this results in a transmission time of 4 x 7 x 5 ms = 140 ms via the AS-Interface. Thus the total transmission time for 4 analogue values ideally is 240 ms (conversion time) + 140 ms (transmission time) = 380 ms.
