Fan modules

The M2004 appliance has four fan modules. Each fan module contains a cooling fan and has an associated LED that indicates the status of the module.
  • Single flash when power is first applied.
  • Steady when the fan is operating at less than 1200 RPM or when a fault.
  • Not illuminated when within design specifications.
  • Not illuminated when no power is present.

The speed of the fans is responsive to the temperature of the appliance as measured by internal sensors. As the temperature changes, the fan speed changes to compensate.
