SCF0 – Sets the scale factor for CONTROLLED MOTOR speed, displayed on readout in TACH mode
with DipSW 5 ON.
SCF0 allows the display to show units other than motor RPM if desired. For example, Feet/Minute
may be displayed for a conveyor, or Gallons/Hour for a pump. It is set by entering the desired readout
when full input signal is applied. SCF0 unites are displayed when DipSW 5 ins ON.
SCd0 – Places a decimal point in the display when in TACH mode.
SCd0 may be set to 0, 1, 2, or 3, corresponding to the number of places from the right-hand side. It
can be used for increased display resolution when SCF0 is set to a low number. For example, if 0-10
volts corresponds to 0-1 foot/minute, SCd0 should be set to 3, to move a decimal point to three places
from the right, giving a display range of 0.000 to 1.000.
FEd1 – Sets the internal scale factor, on which the user-set ratio is based.
FEd1 allows different actual motor speeds to be had with full input, and the follower ratio set to an
arbitrary value. It is nominally set to the value of 137, which allows full input (10 Volts, 20 mA, or
full CW pot rotation) to give full motor speed (1800 RPM with a 60 PPR digital tach).
SCF1 – Sets the scale factor for the REFERENCE signal, displayed on readout in TACH mode with
DipSW 5 OFF.
SCF1 refers to the analog REFERENCE signal.
SCd1 – Places a decimal point on the display when in TACH mode.
SCd1 may be set to 0, 1, 2, or 3, corresponding to the number of places from the right-hand side. It
can be used for increased display resolution when SCF1 is set to a low number. For example, if 0-10
volts corresponds to 0-1 foot/minute, SCd1 should be set to 3, to move a decimal point to three places
from the right, giving a display of 0.000 to 1.000.
Some examples of different parameter settings:
1). 0-10 volts corresponds to 0-1800 RPM.
SCF0 to 1800, SCd0 to 0, FEd1 to 137.
PS-1 at 1.000 gives 1800 RPM, PS-1 at 0.500 = 900 RPM.
2). 0-10 volts corresponds to 0-2500 bottles/hour, with PS-1 set to 1.000
SCF0 to 2500, SCd0 to 0, Fed1 to 137.
Changing PS-1 to 0.500 would produce 1250 bottles/hour with full input.
3). 0-5 volts corresponds to 0-1800 RPM
SCF0 to 1800, SCd0 to 0, FEd1 to 68.
Changing PS-1 to 0.900 would result in 1620 RPM with full input. Changing PS-1 to 1.100
would result in 1980 RPM with full input, (5 volts).
