ATTENTION!
The constant regulating outputs 0/40 ... 20 mA of
the main board are also allocated automatically in
the software configuration as per a fixed rank order
of the terminals, in accordance with the allocation
procedure for the output components.
Ranking of the outputs for automatic allocation:
1. Control output Disinfection
2. Control output pH value
3. Controller output for combined chlorine
4. Controller output for conductivity
5. Flocculation pump output
In the same way the clamps are assigned in a firm order.
• Terminals 15/16
• Terminals 13/14
• Terminals 11/12
• Terminals 9/10
• Terminals 7/8
The clip allocation is automatically displayed at the end of the config-
uration.
