2 Functions and features

• AC2488: 8 inputs CTT3 (AS-i profile S-7.A.A) / AS-interface version 3.0 /

master profile M4 / extended addressing mode: yes / maximum number of

modules per master: 62

• AC2489: 2x4 inputs (AS-i profile 2x S-0.A.E) / AS-interface version 3.0,

backwards compatible / master profile M3 or M4 / extended address mode:

yes / maximum number of modules per master: 31 (2 independent A/B slaves

per module)

3 Installation

► Disconnect power before installation.

► For installation choose a flat mounting surface.

The entire bottom of the module must lie flat on the mounting surface.

► Fix the module onto the mounting surface using M4 screws and washers.

4 Electrical connection

The unit must be connected by a qualified electrician.

The national and international regulations for the installation of electrical equipment

must be adhered to.

► Disconnect the installation from power and connect the unit.

To ensure the protection rating:

► Connect the plugs of the sensors to the M8 sockets.

► Tighten firmly, recommended tightening torque 0.3...0.5 Nm.

► Cover the unused sockets with the enclosed protective caps.

► Tighten firmly, recommended tightening torque 0.3...0.5 Nm.

0 periphery fault indication not active

In the AS-i network the AC2489 module functions like 2 independent A/B slaves.

5 Addressing

► Addressing the unit via the M12 connector (AS-i); the address is set to 0 at the

factory.

5.1 Addressing the AC2489 module

In the factory setting, initially only the first slave gives a signal on address 0. It can

be addressed to any address between 1A...31B.

If this slave is addressed, the second slave with the address 0 appears

automatically in the display. Now this slave can be addressed to any address

between 1A...31B.

Both slaves can be assigned any A/B addresses (e.g. 3A/6A or 9A/25B....).

No address can be assigned twice (e.g. 3A/3A or 9B/9B).

If a slave with the ID code "A" (extended address mode possible) is used in

combination with a master of the 1st generation (version 2.0),

- the parameter P3 must be 1 and the output bit D3 must be 0.* The output bit

D3 must not be used.

- an address between 1A and 31A must be assigned to this slave.

* default setting

5.1.1 Restore the factory setting (address both slaves to 0) to AC2489

Recommendation:

Use the addressing unit AC1154 to restore the factory settings.

When AS-i masters are used and „automatic addressing“ is activated restoring the

factory settings is reversed.

Using the addressing unit AC1154 the factory settings of the module are restored

by writing a 0 to ID1 of the second slave (factory setting ID1 = 2).

When the factory settings are restored via the AC1154 the status message [F3] is

displayed.

► Press mode button once to close the status message.

► Operating mode ID2 appears.

► Then press the mode button as long as the addressing mode ADDR is visible

to display the factory settings (address 0).

6 Settings
