29. ANALOG OUTPUT #2 LOW
ENGINEERING UNITS (EGU)
USE PARAMETER #29 TO SELECT THE
THRESHOLD OF ANALOG OUTPUT #2 EFFECT.
RANGE OF VALUES: FFFE 7961h to 0001 869Fh
-99,999 to +99,998 (dec.)
Default Value: 0000 0000h 0 (decimal)
(See Parameter 14 for the definition
and purpose of EGU)
Parameter #29 sets the point, in EGU’s, at which
the Analog Output #2 will be -10VDC.
30. ANALOG OUTPUT #2 HIGH
ENGINEERING UNITS (EGU)
USE PARAMETER #30 TO SELECT THE MAXI-
MUM ANALOG OUTPUT #2 EFFECT.
RANGE OF VALUES: FFFE 7961h to 0001 869Fh
-99,999 to +99,998 (dec.)
Default Value: 0000 0096h 150 (decimal)
If parameter #30 is greater on the absolute scale
than parameter #29, the voltage at Analog Output #2
will be proportionally scaled from the low EGU’s
(#29) to +10VDC at the high engineering units
(#30).
If parameter #30 is less than parameter #29 on
the absolute scale, then the sense of the output will be
inverted, i.e., the higher voltage (on an absolute scale
from -10VDC to +10VDC) will be present at the low
EGU setting (parameter #29) and the lower voltage
will be output at the high EGU setting (parameter
#30).
