Pure electrical circuit lines without any symbolsFunction and features
The AS-i PCB detects up to two unsafe switching states, e.g. 1 or 2-channel mechanical contacts.
Mounting
Install the AS-i PCB in a protected location (e. g. control cabinet, housing). The appropriate housing must have a protection rating of at least IP 54. Carry out a set-up test after installation of the AS-i PCB.
Electrical connection
Connect the AS-i PCB to two mechanical NO or NC contacts. In doing so, the two outer mechanical pins are connected to one side of the contacts (I1-2 / I2-2). The other side of the contacts is connected to the two black wires (I1-1 / I2-1).
Insulate unused open wires. The connection wires of the AS-i PCB must not be extended.

Addressing
When mounted and wired the PCB can be addressed via the addressing unit AC1144 using the cable (E70032).
Assign a free address between 1A/1B and 31A/31B. At the factory the address is set to 0.
If a slave with the extended addressing mode is used in combination with a master of the first generation (version 2.0), the parameter P3 must be 1 and the output bit D3 must be 0*. The output bit D3 and the parameter bit P3 must not be used.
* Default setting
If a slave with the extended addressing mode is used in combination with a master of the first generation (version 2.0), an address between 1A and 31A must be assigned to this slave.
Operation
Check the reliable functioning of the unit. LED display:
• LEDs 1 yellow: inputs switched (I1, I2)
• LED 2 green: voltage supply ok (PWR)
• LED 2 red lights: AS-i communication error, slave
does not participate in the “normal” exchange of data, e.g. slave address 0 (FAULT)
- External LED output (X1-X2): output O-1
(The output LED can be set as a static or dynamic output by the host system)
Limited voltage
The device shall be supplied from an isolating transformer having a secondary Listed fuse rated 5.0 A.
