Important:
Both slaves can be assigned any A/B addresses (e.g. 3A/6A or 9A/25B
etc.). No address can be assigned doubly (e.g. 3A/3A or 9B/9B etc.).
Restore the factory setting (address both slaves to 0)
Using the addressing unit AC1154 the factory setting of the module is
restored by writing a 0 to ID1 of the second slave (factory setting ID1
= 2) by the internal software.
If a slave with the ID code "A" (option of extended addressing mode)
is connected to a master of the first generation (version 2.0), the para-
meter P3 must be 1 and the output bit D3 = 0*. The output bit D3
must not be used.
If a slave with the ID code "A" (option of extended addressing mode)
is connected to 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. Indication by LEDs:
• LED 1 yellow:
• LED PWR green:
• LED FAULT red is lit:
• LED FAULT red flashing: periphery fault, e.g. overload or short-cir-
Overload and short circuit of the input supply are signalled as peri-
pheral fault to the AS-i master (version 2.1 or higher).
