START
- Pressing “A”, starts the
process by energizing the PRESET and
PREWARN relays. Press “CLR” to reset
Batch Total before starting new batch.
STOP
- Pressing “B”, will temporarily
stop the process by de-energizing the
PRESET and PREWARN relays. Use
START to continue the process from
where it stopped.
RATE/TOTAL
- Pressing “C” toggles
between rate and total count displays.
The rate display has an “R” on the left
side of the screen.
MENU
- Pressing “D” takes the unit out of
the Run Mode and into the Programming
Mode (See Programming, Page 43 and
45). “D” is also used make to some
programming selections.
ENT
- With Count showing in the Run
Mode, pressing “ENT” displays the
Grand Total, which begins fl ashing on
the screen. Press “ENT” again to return
to the Count. In the Programming Mode,
“ENT” is used to accept a selection (See

CLR
- When the count total is displayed,
pressing “CLR” will reset the counter to 0
or to Preset A depending on how it was
programmed. When the Grand Total is

Weighted Averaging
Version 8.7 of the batcher software includes
weighted averaging of the rate display. Weighted
averaging is not available on units with 16 Point
Linearization.
Weighted averaging can be used to create a more
stable display when the rate input is fl uctuating.
A weight, “W”, from 00 to 99 is applied to the old
rate data before the new rate data is sent to the
display. The following equation is used:
W = Weight (00-99)
If a weight of 00 is used, the new rate data will
go directly to the display without being averaged.
If a number other than 00 is entered for the
weight, then the new data will be averaged with
the old data before being sent to the display.
Higher weight numbers will create a more stable
rate display. Small rate changes will be more
noticeable when lower weight numbers are used.
Programming Weighted Averaging
1. In the Program Mode, got to the RATE sub menu
and program the K-FACTOR, the WINDOW, and
the SIG FIG parameters.
2. When the display shows WEIGHTXX (XX
represents the current WEIGHT value), either
accept the current value and return to the Run
Mode by pressing “ENT” or clear the current value
by pressing “CLR”.
3. If the current value was cleared, the display
shows WEIGHT00. Using the keypad, enter a
new WEIGHT value from 00 to 99. Press “ENT” to
accept the new value and return to the Run Mode.

Remote Start, Stop, and Reset
A 4 to 30 VDC positive pulse will activate these
inputs. Remote Start, Stop, and Reset is not
available on units ordered with the Control Input
option 7A (4-20 mA In, 4-20 mA Out).
START (Pin 10):
When activated, the unit will
START as described in Front Panel Operation.
STOP/RESET (Pin 5):
When activated, the unit will
STOP (If the unit is started and the batch is not
complete). A second pulse to pin 5 will reset the
counter (When the unit is stopped or when the
batch is complete). If pin 5 is held high (4 to 30
VDC), the display will fl ash “STOPPED” and any
start inputs will be inhibited.
