723PLUS Digital Marine Control
07 TORQUE INPUT % displays the torque input of 4–20 mA converted to a
percentage. When finished calibrating the 03 SCALED ACT COMMAND % and
the 07 TORQUE INPUT % settings, this value and the TORQUE INPUT % will
read approximately the same values from no load to full load. This a good way of
verifying calibration.
Check torque calibration with the torque input at minimum torque and maximum
torque. At these torque points, the 03 SCALED ACT COMMAND % prompt and
the 07 TORQUE INPUT % should display 0% and 100% respectively. If there are
discrepancies, re-calibrate 04 TORQUE IN @ NO LOAD, 05 TORQUE IN @
MAX LOAD, 01 ACT OUT % @ NO LOAD and 02 ACT OUT % @ MAX LOAD as
needed to meet this requirement.
M**ANALOG OUT CALIB**
The ANALOG OUT CALIB header contains all the output selections
for the two analog outputs (Analog Output #2 and Analog Output #4),
Tach Output and Rack Position (mA).
01 TACH OUT FILTER (Hz)(*0.1-20.0)—This value adjusts the cutoff frequency
of a low pass filter used on Analog Output 2. To use this feature, set the cutoff
frequency below 15.9 Hz. To disable this filter, set the cutoff frequency above
15.9 Hz.
02 TACH OUT MIN (*–30 000.0–30 000.0)—This value adjusts the engineering
units which will output 4 mA at Analog Output #2.
03 TACH OUT MAX (*–30 000.0–30 000.0)—This value adjusts the engineering
units which will output 20 mA at Analog Output #2.
04 TACH OUTPUT (4–20 mA)—This is a display of the current in milliamps of
the tachometer output.
05 RACK OUT FILTER (Hz)(*0.1-20.0)—This value adjusts the cutoff frequency
of a low pass filter used on Analog Output 4. To use this feature, set the cutoff
frequency below 15.9 Hz. To disable this filter, set the cutoff frequency above
15.9 Hz.
06 RACK OUT AT MIN (*–30 000.0–30 000.0)—This value adjusts the
engineering units which will output 4 mA at Analog Output #4.
07 RACK OUT AT MAX (*–30 000.0–3 000.0)—This value adjusts the
engineering units which will output 20 mA at Analog Output #4.
08 RACK OUTPUT (4–20 mA)—This is a display of the current in milliamps of
the rack output.
09 RACK OUTPUT %—This is a display of the percent of the rack output
(0–100).
10 TORQUE INPUT OFFSET (*-5000.0, 5000.0)—This value adjusts the
engineering units which will output 4.0 mA when the input is at 4.0 mA. The value
is read on 12 TORQUE INPUT (4–20 mA) below.
11 TORQUE INPUT GAIN (*0.5, 20)—This value adjusts the engineering units
which will output 20.0 mA when the input is at 20.0 mA. The value is read on 12
TORQUE INPUT (4-20 mA) below.
