1.3.2 Advanced Cascade Controller MCO 102

The MCO 102 option supports a maximum of 8 pumps and is able to alternate the lead pump with 2 frequency converter relays per pump. This reduces
the need for external auxiliary switches as well as cost of installation.
When MCO 102 (C-option) is used, the number of relays can be increased to a total of 13 by adding the MCB 105 (B-option).
NB!
Before start, interrupt the power supply to the frequency converter. Never install an option card into the frequency converter during
operation.
