5.6.2 SPECIFICATION OF THE FAN CONTROL
The internal fan cools down the MTB and Power blocks.
The external fans cool down the whole unit.
• The operating temperature of the fan is higher than the ambient temperature, because the sensor temperature is read by
the microcomputer.
• If the critical values for signals are displayed in the address circuit, the fan may be activated or be rotated at higher speed
in response to values lower than the set temperature values shown above.
• When the temperature rises, the sensor voltage of TEMP2 decreases.
• When the voltage of the DAC output for external FAN decreases, rotation speed of FAN rises.
