Example: Check IO configuration

Wizard assignment of inputs and outputs (I/0)

Once the wizard is applied, the IO functions are automatically
assigned to hardware inputs and outputs�
The screens below shows how the IO functions are assigned
according to the example�
Main menu
Digital outputs

Assignment of inputs and outputs

The table indicates rules for assignment of inputs and outputs via the wizard�
Digital outputs (DO1-DO8)
PWM outputs for capacity
control of Digital scroll or
Stream 4 compressor are placed
on the solid state relays DO5
and DO6
Starting from DO1:
Compressor start relays
followed by unloading valves
for respectively suction group
A and B
Condenser fan
Injection ON for A/B *
Alarm relay
* Special features to be enabled through configuration screens. Not part of the wizard setup.
