Fan Cooling - Dynacord V Series Installation Manual

22 en | General installation procedures
For fixed amplifier installations in a device control room that incorporate a central
air‑cooling system or air conditioners, calculating the maximum heat emission may be
necessary. See also Mains operation and resulting temperature, page 23.

Fan cooling

The device is designed for desktop operation without the need to run the fan, using
convection cooling. This ensures silent running in most conditions.
The temperature of the power amp's channels are supervised and monitored, as well as the
power supply and control unit section. These parameters determine the fan activation to
prevent output limiting from occurring.
The fan has two optimized performance levels for low and high and use the same criteria to
determine the appropriate level of force cooling required.
The rotation of the fan is supervised. In case of a lock condition where the fan is not
rotating, this is indicated with flashing warning LEDs on the front panel and the Fault relay.
However, even in such a condition the amplifier will operate without switch‑off or reduction
if supervised and monitored levels are within the range of silent running parameters.
