NOTICE
If the system requirement is to have the internal pack
controller for 3 compressors plus bypass valve
connected, specify FC 103 with the extra relay card (MCB
105) mounted inside the frequency converter.
Programme the bypass valve to operate from one of the
extra relay outputs on the MCB 105 board.
This is needed because the standard relay outputs in the
FC 103 are used to control the compressors in the pack.
