44 Installation and Operation Manual
4.32 Pulses Per Unit Measure
This parameter is a result of how many pulses the
integrator needs to count for the belt to move just one
unit of measure. The integrator calculates this during a
speed calibration.
The default value for this parameter is: 6.0.
4.33 Test Duration
T h i s p a ra m e t e r i s t h e v a l u e u s e d f o r a t i m e d
calibration. This value is represented in seconds. Enter
the desired length of time to run the timed calibration
using the numeric keypad and press
enter to save that
value.
It sh ould be noted that per Handbo ok 44, the
requirement to test at least three revolutions of the
belt. So based on the length of time it takes for a
complete revolution, times that by three to get your
parameter.
The default value for this parameter is: 60 seconds.
4.34 Tons per Pulse (output)
This parameter defines how many totalizer units are
accumulated to generate a pulse output for a remote
totalizer. This is a numeric value that can be keyed in
using the integrator numeric keypad and sends a pulse
out of the digital output bit which is defined by the
totalizer pulse bit (4.41) setting.
The default value for this parameter is 0.1.
4.35 Pulse Duty Cycle (in seconds)
This parameter defines how long the above output
(tons per pulse) stays on. This is required for older
model PLC’s in order for the pulse to be recognized.
This is a numeric value that can be keyed in using the
integrator numeric keypad.
The value is a representation of seconds and its default
value is 0.25 seconds.
4.36 Low Rate Alarm Value (%)
This value determines the point at which the low rate
alarm will become active.
The default value for this parameter is: 0.
4.37 Maximum Speed Value
The value that is needed to determine an over speed
condition.
The default value is 300.
4.38 Low Rate Alarm Bit
This parameter defines which digital output bit will
activate for the low rate alarm, which is determined by
the low rate alarm value setting.
The default value for this parameter is: 0.
4.39 High Rate Alarm Bit
This parameter defines which digital output bit will
activate for the high rate alarm which is determined by
the scale capacity settings.
The default value for this parameter is: 0.
