Specifiy the scale number used as the source for the setpoint.
TRIP Higher
Lower
Inband
Outband
Specifies whether the setpoint is satisfied
when the weight is higher or lower than the
setpoint value, within a band established around the value, or outside of that band.
In a batch sequence with TRIP=HIGHER, the associat
ed digital output is active until the
setpoint value is reached or exceeded; with TRIP=LOWER, the output is active until the
weight goes below the setpoint value.
BANDVAL number
HYSTER number Specifies a band around the setpoint value that must
be exceeded before the setpoint,
once off, can trip on again.
PREACT Off
On
Learn
Allows the digital output associa
ted with a setpoint to shut off before the setpoint is
satisfied to allow for material in suspension.
The ON value adjusts the setpoint trip value up or down (depending on the TRIP
pa
rameter setting) from the setpoint value using a fixed value specified on the PREVAL
parameter.
The LEARN value can be used to automatically adjust the pr
eact value after each batch.
LEARN compares the actual value at standstill to the target setpoint value, then adjusts
the preact PREVAL by the PREADJ value times the difference after each batch.
PREVAL
PREADJ 0.500000
0-9999999
Preact adjustment factor. For setpoints wi
th PREACT set to LEARN, specifies a decimal
representation of the percentage of error correction applied (0.05 = 50%, 1.0 - 100%)
each time a PREACT adjustment is made.
PRESTAB 0
0-65535
Preact stabilization time-out. For
setpoints with PREACT set to LEARN, specifies the
time, in 0.1-second intervals, to wait for standstill before adjusting the PREACT value.
Setting this parameter to a value greater than zero disables the learn process if standstill
is not achieved in the specified interval.
PCOUNT 1
0-65535
Preact learn interval. For setpoints with PREACT se
t to LEARN, specifies the number of
batches after which the preact value is recalculated. The default value, 1, re-calculates
the preact value after every batch cycle.
RELNUM 1

For the percent relative setpoint, specifies the nu
mber of the relative setpoint. The target
weight for the %REL setpoint is determined as follows:
The percentage (specified on the VALUE parameter of the %REL setpoint) of the target
value of the relative setpoint.
