%REL Percent relative setpoint. Performs functions based on a specified percentage of
the target value of a referenced setpoint, using the same weight mode as the
referenced setpoint. The actual target value of the %REL setpoint is calculated as
a percentage of the target value of the referenced setpoint. X X
RESREL Relative to a result setpoint. Performs functions based on a specified percentage
of the captured value of a referenced setpoint, using the same weight mode as
the referenced setpoint. The actual target value of the RESREL setpoint is
calculated as a percentage of the captured value of the referenced setpoint, rather
than the target value. X X
PAUSE Pauses the batch sequence indefinitely. A BATSTRT signal must be initiated to
continue the batch process. X
DELAY Delays the batch sequence for a specified time. The length of the delay (in tenths
of a second) is specified on the VALUE parameter. X
WAITSS Wait for standstill. Suspends the batch sequence until the scale is at standstill. X
COUNTER Specifies the number of consecutive batch sequences to perform. Counter
setpoints should be placed at the beginning of a batch routine. X
AUTOJOG Automatically checks the previous weight-based setpoint to verify the setpoint
weight value is satisfied in a standstill condition. If the previous setpoint is not
satisfied when at standstill, the AUTOJOG setpoint activates the digital output of
the previous weight-based setpoint for a period of time, specified on the VALUE
parameter. The autojog process repeats until the previous weight-based setpoint
is satisfied when the scale is at standstill.
Note
The AUTOJOG digital output is typically used to signify that an
autojog operation is being performed. AUTOJOG should not be
assigned to the same digital output as the related weight-based
setpoint.
X
COZ Center of zero. Monitors for a gross zero condition. The digital output associated
with this setpoint kind is activated when the referenced scale is a center of zero.
No value is required for this setpoint. X
INMOTON In motion. Monitors for an in-motion condition. The digital output associated with
this setpoint is activated when the scale is not at standstill. No value is required for
this setpoint. X
INRANGE In range. Monitors for an in-range condition. The digital output associated with
this setpoint is activated when the scale is within capacity range. No value is
required for this setpoint. X
BATCHPR Batch processing signal. The digital output associated with this setpoint is
activated whenever a batch sequence is in progress. No value is required for this
setpoint. X
TIMER Tracks the progress of a batch sequence based on a timer.
The timer value, specified in tenths of a second on the VALUE parameter,
determines the length of time allowed between start and end setpoints. The
indicator START and END parameters are used to specify the start and end
setpoints. If the END setpoint is not reached before the timer expires, the digital
output associated with this setpoint is activated.
X
CONCUR Allows a digital output to remain active over a specified portion of the batch
sequence. Two types of concur setpoints can be configured:
Type 1 (VALUE=0): The digital output associated with this setpoint becomes active
when the START setpoint becomes the current batch step and remains active
until the END setpoint becomes the current batch step.
Type 2 (VALUE > 0): If a non-zero value is specified for the VALUE parameter, that
value represents the timer, in tenths of a second, for this setpoint. The digital
output associated with this setpoint becomes active when the START setpoint
becomes the current batch step and remains active until the timer expires.
