the OUTC and the OUTH output are 0. When it is negative, the opposite
occurs; for each value included in the dead band (now named cross band),
both the
OUTC and the OUTH are different from 0.
• If DTRK (Track) is active, the outputs are set according to the value of the
analog input
TRK . This signal has a range from [-100.0 … +100.0] and it
drives both
OUTH and OUTC . When its value is in the range -100.0...0, it
means that a Cool action must be taken; therefore,
OUTH is set to 0.0, while
OUTC is set to the value of TRK , with the sign inverted. Inversely, when it is
in the range 0…100.0,
OUTC is set to 0.0, while OUTH is set to TRK .
Please note that the tracking value is not affected by the
DBND parameter.
• If the DAM input is active (and DTRK is inactive) the outputs are set
according to the value of the analog input
AM_VAL . This signal has a
range from
[-100.0...+100.0] and it drives both OUTH and OUTC . When its
value is in the range -100.0...0, it means that a Cool action must be taken;
therefore,
OUTH is set to 0.0, while OUTC is set to the value of TRK, with
the sign inverted. Inversely, when it is in the range 0...100.0,
OUTC is set
to 0.0, while
OUTH is set to TRK . These values are valid if the DBND of the
phase splitter is set to 0.0, otherwise they slightly change.
•If
DAUX ( Aux ) is active(and both DAUX and DTRK are inactive), the
outputs are set according to the value of the analog input
AUX . This signal
has a range from
[-100.0...+100.0] and it drives both OUTH and OUTC .
When its value is in the range -100.0...0, it means that a Cool action must
be taken; therefore,
OUTH is set to 0.0, while OUTC is set to the value of
AUX , with the sign inverted. Inversely, when it is in the range 0...100.0,
OUTC is set to 0.0, while OUTH is set to AUX . These values are valid if the
DBND of the phase splitter is set to 0.0, otherwise they slightly change.
