External Fan Control
The TECSource has a built-in user adjustable 4-12V DC power supply designed
to provide up to 350mA to an external fan, such as those built into the 240
Series LaserMounts. When using the TECSource with mounts that require a
fan, no additional external power supply is needed, and the Arroyo 126xB series
cables all include the wiring to connect the fan power to the mount.
Fan control is setup in the menu using the Ext Fan, Ext Fan Pwr, Ext Fan
Mode, and Ext Fan Off settings.
Ext Fan can be set to Off, Slow, Medium, Fast, or Custom. When set to Off, the
fan power is never turned on. Slow, Medium, and Fast correspond to 9V, 10.5V,
and 12V. To select a different voltage, choose the Custom setting and then
adjust the Ext Fan Pwr menu item to the desired voltage, from 4.0V to 12.0V.
The fan on/off mode can be controlled using the Ext Fan Mode setting. There
are five modes:
Auto Fan is turned on whenever the TEC output is on, and turns off when the
TEC output is turned off.
On Fan is always on.
Delay Similar to the Auto mode, the fan is turned on whenever the TEC output
is on, but when the TEC is turned off, the fan will remaining running for
an addition number of minutes as defined by the Ext Fan Off setting.
Cool Fan is turned on whenever the TEC output is on and cooling, off
otherwise.
Heat Fan is turned on whenever the TEC output is on and heating, off
otherwise.
