DTA01, DTA02, PTA01, PTA02
Mode of Operation
DTA01, DTA02, PTA01 and
PTA02 monitor the resis-
tance value of the PTC
resistors connected to the
terminals T1 and T2 (or 5
and 6). This value is related
with their temperature (often
the three coils of a motor) so
to offer a prompt reaction to
over temperature.
Example 1 - DTA01 or PTA01
The relay operates as long
as the measured resistance
is below the rated value. The
relay releases if the mea-
sured resistance (i.e. the
temperature of the motor
coils) exceeds the rated val-
ue.
Example 2 - DTA02 or PTA02
The relay operates and the
yellow LED is ON as long as
the measured resistance is
below the rated value. The
relay releases and the yellow
LED is OFF if the measured
resistance (i.e. the tempera-
ture of the motor coils)
exceeds the rated value.
Provided that the resistance
has dropped below the rat-
ed value (i.e. the tempera-
ture of the motor coils has
returned cold), the relay
operates when the intercon-
nection between terminals
Z1, Z2 or 8, 9 is interrupted
or the reset button on the
front of the unit is pressed.
