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

On the display, the icon indicates which of the four possible target cosines was selected.
4�8�- OUTPUTS
The device 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
“5.17.- FAN”
, 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, optoisolated NPN transistors (terminals 34, 35 and 36 of
Figure 2
), fully
programmable; see
“5.21.- ENABLING ALARMS”.
Computer SMART III 6
model:

Six output relays (terminals 15 to 21 of
Figure 2
) for regulating the cos φ by means of capac-
itors.
Computer SMART III 12 model:

Twelve output relays (terminals 15 to 27 of
Figure 2
) for regulating the cos
φ
by means of
capacitors.
Computer SMART III 14
model:

Fourteen output relays (terminals 15 to 27 and 42 to 44 of
Figure 2
) for regulating the cos φ
by means of capacitors.
