Ignore the flash codes for approx. 2min (acknowledge alarm, if any) after
connecting the chlorine sensor.
If the LEDs repeatedly start to send one and the same sequence of flash
codes, the bus has to supply too many devices.
In this case, loop a (further) N module into the bus (see operating instructions
Multi-Channel Measuring and Control System DULCOMARIN
Pool Controller and Disinfection Controller DXCa Part 1, Assembly and Instal-
lation). In case of all other flash codes, contact the customer service!
