!! W A R N I N G !! Relays and solenoids connected to the Be42 must be suppressed
using flywheel diodes or suppression devices as indicated in section 18.0. We
recommend that you connect a 1A Fuse (fast BLOWING) in series to the terminal #24;
it will protect the controller against large spikes on the power supply.
