USER MANUAL AC2729 IFM
9 10 10Function 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, hous- ing). 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. ENGLISH
AS-i Fault LED I-1 LED I-2Wiring A+: AS-i + A-: AS-i - I1-1/I1-2 I2-1/I2-2: switching input mechanical contact I1 / I2 LEDs 1: switching status indication inputs I1, I2 LEDs 2: AS-i, FAULT X1-X2: external LED output Data bits Addressing When mounted and wired the PCB can be addressed via the address- ing 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.
- 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.
