ROV ROV and RHL parameters work together.
Their combined purpose is to allow the adjustment of
one Regrind component up or down based on input from one or two lever sensors.
LEVEL SENSORS are required for this parameter to work.
Both ROV and RHL must be set for these parameters to have any effect.
The component being controlled is ALWAYS automatically
assigned to the bottom set of thumbwheel switches.
The first digit of the ROV parameter indicates which component is controlled by the adjustment
routine. Only components 1 through 9 may be controlled.
The last digit determines the adjustment rate. Zero in the last position means make the full
adjustment immediately. Any value from 1 to 9 indicates the percentage adjustment that will be
made each cycle when the level sensor condition changes. See RHL below for examples.
RHL LEVEL SENSORS are required for this parameter to work
Use only if you have regrind level sensors fitted
RHL instructs the controller to change the regrind setting of one selected regrind component if
optional level sensors in the regrind hopper indicate high or low conditions. The component to be
changed is determined by the first digit of the ROV parameter above.
If set to all zeros (RHL 00000), then this parameter is ignored.
ROV alters the way RHL is interpreted.
If the last digit of ROV = 0, (ROV x0000), then RHL numbers indicate NEW settings that are to be
run when regrind level is high or low.
If the last digit of ROV = 1 to 9 (ROV x0001) to (ROV x0009), then RHL indicates upper and lower
regrind usage limits only, and regrind usage will be adjusted slowly, to these limits, based on the
ROV number.
IF ROV equals zero (ROV 10000):
In this (and all) examples, ROV is selecting component 1 as the controlled component. (ROV
10000)
If RHL is set to any value, the first 3 digits of the parameter indicate a new Regrind setting to use
when the material level is ABOVE the HIGH level sensor; (sensor is covered). The last 2 digits
indicate a new setting to use if material level is BELOW the LOW sensor; (both High and Low
sensors are uncovered).
In other words, RHL allows the selection of a percentage that is HIGHER then normal, and a
percentage that is LOWER then normal. NORMAL is what you put on the bottom thumbwheel
switch.
Sensors are assumed to be covered when NO signal is returned. If a sensor is unplugged from the
controller, it is read as "covered".
If you only have ONE SENSOR, it must be used as a HIGH level sensor. The absence of a sensor
is read as a covered sensor; so the absence of the high sensor would signal the system to run at
the high setting all the time. This would not be acceptable. The absence of the LOW sensor
simple prevents the system from ever thinking it is very low. This is acceptable.
