SYSTEM OVERVIEW
General information
The MS management system offers advanced fan control features. MS management system requires a specific
configuration of the fan electronic driving box. This configuration can be modified to standard mode (without speed
control = ST mode) by simply moving a jumper on the electronic driving box (please refer to the technical file of the
fan for more information).
MS management system is composed of:
 1 circuit-breaker 230 VAC - 2A
 1 supply 230 VAC - 5 V DC

1 relay for alarm switching
 1 Main module to manage from 1 up to 25 fans

1 Fan module per fan

1 or 2 digital temperature sensors (+ possibility of wind gauge or clock)
These components can be placed in an IP65 electric box (if outside) not included, and clipped on DIN rail. They
are interconnected through RJ11 wires (supplied) of about 25 cm
1
. The connection of Fan modules to the fans is
realised by the mean of four wires standard cable.
