4�7�- INPUTS
The
Computer SMART III FAST
comprises two digital inputs (terminals 31 and 32 of
Figure 2
) for acti-
vating any of the four target cos
φ
, in other words, the desired power factor for the installation, which
can be programmed in the unit. See “
5.3.- TARGET COS φ

On the display, the icon indicates which of the 4 possible target cosines was selected.
4�8�- OUTPUTS
The unit features:

A relay (terminals 37 and 38 of
Figure 2
) dedicated to activating a fan when a pre-determined
temperature is exceeded, which can be programmed in
"5.16.- FAN ”
, is also connected to the
Fan LED.

A fully programmable alarm relay (terminals 39, 40 and 41 of
Figure 2
), see
“5.21.- ENABLING
ALARMS”

Two digital outputs, fully programmable optoisolated NPN transistors (terminals 34, 35 and
36 of
Figure 2
), see
“5.21.- ENABLING ALARMS”
Computer SMART III FAST 6 model:

Six optoMOS relay outputs (terminals 15 ...21 of
Figure 2
) for the regulation of cos
φ
via ca-
pacitors.
Computer SMART III FAST 12
model:

Twelve optoMOS relay outputs (terminals 15 ...27 of
Figure 2
