P682 Average Idler Spacing
For test load data entry (P680=2) this parameter is enabled for entry of the average idler
space before and afer the scale. The length units are determined in P004 (imperial=1,
metric=2).
P690 Speed Constant Entry
Selects the method by which the speed constant is entered, for both speed sensors
1)
(P690-01 or 02) .
1 = calculated, this selection returns the program to appropriate P015 for entry of speed
constant:
speed sensor pulses per revolution
pulley circumference (m or ft) / revolution
e.g:
MD-256 mounted on 6" Bend Pulley
256 pulses per revolution = 534.694 pulses per meter or 162.975 pulses per feet
0.478meters per revolution
OR
2 = sensor data, the selection forwards the program to P691 and P692 for entry of the
required sensor data for automatic calculation. The calculated value is automatically
entered into P015-01 or 02.
P691 Drive Pulley Diameter
For speed constant entry (P690 =2), this parameter is enabled for entry of the drive pulley
diameter (P691-01 or 02)
Enter the pulley diameter (units determined in P004).
P692 Pulses Per Sensor Revolution
For speed constant entry (P690 = 2), this parameter is enabled for entry of the pulses per
revolution that the speed sensor delivers (P692-01 or 02)
Enter the pulses per revolution from the speed sensor nameplate.
