Use the AS-Interface flat cable (yellow) for connecting the AL-ASI-BD to the network.
When installing AL-ASI-BD refer to figure 2;
1) Remove screw 'A' and keep.
2) Carefully remove the factory fitted expansion port cover.
3) Cut away section 'B' of the
4) Re-locate the AL-ASI-BD on the base unit.
5) Replace screw 'A' and tighten to a torque of 0.4~0.5Nm.
When connecting AS-Interface cable to the module, tighten communication connector pin screws to a
torque of 0.5~0.6Nm.
4. SLAVE ADDRESS SETTING & DIAGNOSTICS
A slave address can be set by the AS-Interface master. When a new station is added to an AS-Interface
Bus the master module will assign the lowest free address.
Slave addresses range from 1 to 31 and, can only be assigned to a module of initial address 0 (zero).
New modules are pre-set to 0 before shipping, if a module has been previously assigned an address other
than 0, it must be reset to 0 before it can be changed to another address.
Many modules can be added to a network at one time, all but one of them should be set in their passive
state (set N1=1). Once the network has been powered up the modules can be individually activated (set
N1=0), where the Master station will assign a station number. Refer to the AS-Interface Master modules
manual for details of how to change station numbers from the AS-Interface Master.
Applicable Error checks
1) If a Communication defect error (M6) occurs;
- Check connections to the AS-Interface master, and that the slave station number is correct.
2) If a Communications power supply error (M7) occurs;
- Check the connection of the AS-Interface Bus cable at each affected unit, also the AS-Interface
power supply and its operation.
