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;
Disconnect all terminals from the power supply before removing the cover.
1) Release screw 'A' and keep.
2) Carefully remove the factory fitted expansion port cover.
3) Cut away section 'B' from the
4) Attach the AL-ASI-BD to the main unit.
5) Tighten screw 'A' to a torque of 0.4 N·m.
When connecting AS-interface cable to the module, tighten communication connector pin screws to a
torque of 0.5 ~ 0.6N·m.
4. SLAVE ADDRESS SETTING & DIAGNOSTICS
The address of AL-ASI-BD must be set from the AS-interface master module. The setting range of the
slave address is 1 to 31. New modules are preset to 0 before shipping, if a module has been previously
assigned an address other than 0, it must be reset to 0 before it need to add into new AS-interface
network.
Refer to the AS-interface master module's manual for details of how to set station address from the AS-
interface master.
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 slave address.
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.
