The preset A output is dedicated to the batch amount. When
START is activated, Relay A will energiz e and remain on until
the batch is complete or the batch is stopped.
PRESET B:
The preset B output can be progr ammed to activ ate as a
Prewarn (for two stage batch control) or activate on Batch Total
or Grand Total (selectable).
When set for PREWARN, Relay B will energize when START is
activated and drop out at Prewarn number before preset.
When set for Batch Total or Grand Total, Relay B will activ ate
when the batch total or gr and total counts up to preset B
amount. The output ON time can be set for a duration (0.01 to
99.99 sec.) or latched (0.00 setting). If a value other than 0.00
is set for the duration, the batch total or g rand total will auto-
reset at preset B.

display updates once per second. The rate meter can be pro-
grammed to sample from 2 to 24 seconds maximum, and auto-
range up to 5 digits of significant inf ormation. The ratemeter dis-
plays in units per second, minute or hour.
Batch or GrandTotalizer: In addition to viewing the batch amount,
a second counter can be viewed. This counter is programmable to
count either the number of batches (Batch Total) or the grand total
count (Grand Total).
RS232/RS422 Serial Interface: If the serial interface option is
supplied, up to 99 units can be linked together. (The terminal
addressing the unit must be capable of driving all loads in the

The MINI-Batcher is the central controller for this feed batching
application. The batcher is mounted on the dispensing truck and
controls the dispensed amount of feed for each batch.
A sensor in the dispensing unit (auger or conveyer) sends pulses
to the MINI-Batcher. This information is scaled by the batcher and
displayed as pounds. The operator simply enters the amount of
feed (in pounds) and presses the START key. Relay A energizes
and sends power to the dispensing unit motor control. As the feed
is dispensed, the MINI-batcher counts the pounds. Relay A drops
out when the count reaches Preset (PRE A). The second counter
is programmed to count the Grand Total. This allows the operator
to keep track of the total amount of feed dispensed at each stop.
The second counter may also be programmed as a Total Batch
counter to keep track of the number of batches at each stop.

MOUNTING
The unit is designed to be mounted with a gasket providing a water tight seal. Two mounting brackets are provided to
secure the unit to the panel. A panel less than .1" may distort if the clamps are screwed too tightly.
Slide the body of the unit through the rubber gasket. Insert the unit into the panel. As shown in "FIG. A", slide the brackets
up the groove to press against the back of the panel. Insert screws into rear of brackets and tighten them evenly and
alternately. Do not over tighten! A normal level of torque is required. Maximum torque should be 3" pounds.
This product is designed to be panel mounted and is NEMA 4 rated if proper mounting procedures are followed and the
required and supplied hardware is correctly used.
If the panel in which the unit is mounted is less than .125 of an inch thick, the possibility exists that there will be some
flexing. Should this flexing occur, the resulting deformation of the panel could cause a loss of the water tight seal. In case
this should occur, the use of silicone or other sealant would be recommended.
This product is designed to the NEMA 4 rated. However, the fact that we are unable to control either the location in which
the device is installed or the actual installation itself requires that the company's liability shall extend only to the repair or
replacement of a defective product.
We are prepared to offer additional assistance in those special situations where normal mounting methods do not seem to
satisfy the customers needs. This assistance may be obtained by calling the factory and asking for Application Engineer-
ing.

WIRING
The rear terminal contains 12 screw terminals for connecting #14 to #28 gauge wire.
The unit is controlled by a microprocessor and, therefore, an electrically "noisy" environment could cause operating
problems. The input power line should not be common to power lines for motors, pumps, contactors, etc.
The unit is designed to be immune from line or RF voltage interference. In some environments voltage spikes of over 100
volts, even 1000 volts, can occur. When common to a power line driving motors voltage fluctuations can be extreme and
rapid. Lines driving DC or AC solenoids, relays, or actuators can also cause problems.
Four sources of noise can occur:
1) AC power line noise - If the unit cannot be connected to a clean power source, an inductive load suppressing device
(MOV as GE # V130LA1 or Resistor Capacitor as Paktron # .2 uf/220 ohm @ 400V) can be installed. Although locating
the suppressor across the AC supply at the unit should help, best results are obtained by connecting the suppressor
across the leads of the "load" at the device causing the spike.
2) Input line noise -The noise is carried on the input and D.C. ground lines. Make sure the input wires are never run into
the unit in a bundle with power input lines. Also, keep these input lines isolated from inductive lines from devices
drawing heavy loads. If there is a possibility of electrical noise, we recommend using shielded cable, with the shield
being hooked to the D.C. ground terminal on the instrument, and to "earth" at one point in the circuit, preferably at the
D.C. ground terminal of the unit.
3) Output lines - The unit has two relay outputs. When these outputs are used to run external relays or solenoids, spikes
can be generated upon activation. This noise can spread through the instrument causing operating problems. If the
source is a D.C. operated device, a general purpose diode (IN4004) placed across the solenoid prevents electrical
noise spikes. Connect the cathode (banded side) to the more positive side of the coil. If the source is an A.C. operated
device, use a MOV or Resistor Capacitor across the coil.
4) 12 VDC output supply - Noise can be generated on the 12 VDC output supply if it is used to drive inductive loads or if
the current draw exceeds 50 mA. Insure that all inductive loads have a diode (such as IN4004) across the coil and that
the current does not exceed 50 mA.

AC / DC Power Connections
NOTE: Connect power only after other connections are finished. Do not touch the live AC power terminals! The unit has been
designed with an isolated AC input. Thus, polarity is not a concern for the AC input. Connect AC power to pins 11 and 12. The chassis
is plastic, therefore earth ground is not used. For D.C. operation, connect + 12V to pin 7 and - D.C. to pin 8.
Sensor Connections
These diagrams show how to hook typical input sensors to the unit. The unit supplies an unregulated 12 Volt (50mA) output to power
these sensors (Pin 7).
A valid pulse is one which makes a transition from the off-state (0 to 1V) to the on-state (4 to 30V): a positive going edge. The input
impedance is 10K Ohms to ground. The unit can be programmed from the front panel for slow switch closure inputs up to 40Hz (select
"Lo CPS"), or solid state switches (select "hi CPS") up to 9.99KHz. No rear terminal jumpers are required. Use PNP (sourcing) type
pulsers.

THEORY OF OPERATION
Relay B Operation
Relay B can be programmed as a prewarn relay or
grand total/batch counter alarm.
When Relay B is set for Prewarn, Relay B will ener-
gized when the batcher is started. Relay B will drop
out when the count is at the selected number (Preset
B) before final Preset A. This is often used for slow
down (2 stage batching).
When Relay B is set for total (Batch or Grand Total),
Relay B will energize for the selected time duration
when the Batch/Grand Total reaches Preset B. If the
Relay is set to latch, it can be reset by resetting the
Batch/Grand Total. (as described above).
Relay B as Scaled Pulse Output
To use output B as a scaled output proceed as follows:
1) Select gr tot under count section of menu.
2) Select tot under relay section of menu.
3) Enter the desired duration for the B Relay.
4) Set Pre B at desired scaling (pre b is a divider).
Maximum output frequency is 15 pulses/second.
Presets
Preset A can be viewed and changed by pressing the
"PRE A" button. The present Preset A will appear.
Press buttons "A" through "E" to load in desired Preset
A. Press the ENTER button once to enter.
Preset B can be viewed and changed by entering the
program menu. Press the PRGM button. PRE B will
appear. Press ENTER. The present Preset B will
appear. Press buttons "A" through "E" to load in de-
sired Preset B. Press the ENTER button once to enter.
VIEW Button
The VIEW button allows you to alternately view:
1. Count of "A" (Batch)
2. Rate of "A" (Batching speed)
3.* A) Grand Total if "gr tot" is selected
B) Number of Batches if " BA tot" is se-
lected
* All decimal points are inverted when Grand/Batch
Total is being displayed.
Batching
After the batcher has been programmed, it will operate
as follows:
The unit will reset to "0" (count up mode) or load
Preset A (count down mode) when RESET/STOP is
activated. (front button or rear input)
When Start (front button or rear input) is activated,
Relay A (and Relay B if Prewarn is selected) will ener-
gize and the right decimal will light. The unit will count
in engineering units corresponding to the input scaling.
If Prewarn is selected for Relay B, Relay B will drop out
when the count is at the selected number (Preset B)
before final Preset A. When Preset A (or "0") is reached,
Relay A drops out and the right decimal turns off. (The
right decimal turns on whenever Relay A is energized).
At the end of the batch the display is immediately
loaded with "P" and Preset A number. At this point you
can:
Press START to reset and start another batch
Press PRE A to change Preset A
Press VIEW to view count (over-run)
Press RESET/STOP to reset to "0" (Preset A)
If RESET/STOP is activated while the unit is started,
Relay A (and Relay B if Prewarn) will drop out and the
last count will remain on the display. Press START to
continue the batch or RESET/STOP to abort the batch.
All starts are inhibited if RESET/STOP is held active.
Grand Total or Batch Counter
The second counter (displayed with inverted decimals)
can be programmed as a Grand Total or Batch counter.
The Grand counter counts the grand total, the Batch
counter counts the total number of complete batches.
These counters can only be reset from the front panel
while viewing them. To reset, press the VIEW key until
the displays shows a number with all decimals lit. Press
RESET/STOP to reset.

by a 5 digit number (xxxxx). The number you enter here will be the code to lock and unlock the unit.
RELAY RELAY - This portion of the menu allows you to set your relay operation variables.
preuu PREWARN - When this is selected Relay B energizes when started and drops out at "Preset B" amount
before batch is complete.
TOT RELAY B FOR TOTALIZER - When this is selected relay B will activate when the selected Grand or
Batch total has reached Preset B.
b##.## RELAY B DURATION - This message will appear when "TOT" is selected. It is the duration which the
relay will remain energized (00.01 to 99.99 sec). If 00.00 is selected, the relay will latch until reset.
When the duration is not at 00.00, the Grand/Batch totalizer will autorecycle.

CALCULATING SCALE FACTORS
The unit has a programmable scale factor to scale the input pulses. It is a 5 digit , floating decimal divider factor. The factor
to enter is the number of pulses per the desired unit of measurement. The factor ranges from 0.0001 to 99999.
Scale factor calculations are simple. Here are some examples:
DECIMAL LOCATION:
When a decimal is desired for display, special care must be taken when programming the Factor ( factor) and Decimal
Location (Dp loc). The factor must be entered in pulses per units desired for display. (i.e. pulse per 1 unit, pulses per 0.1
units, pulses per 0.01 units, etc.) The Decimal Location (Dp loc) controls the decimal placement for the display. For each
decimal place you move for Dp loc, you must also move the decimal for the factor (dp f a).
Example: The flow sensor outputs 678.4 pulses per gallon.
To display whole gallons (1 gal) enter 678.4 for the factor
To display tenths of gallons (0.1 gal) enter 67.84 for the factor
To display hundredths of gallons (0.01) gal) enter 6.784 for the factor
SCALING FACTOR EXAMPLES:
Flow Batching: You want to fill a 55.0 gallon drum. The flow sensor gives 387 pulses per gallon.
Solution - Dial in a scale factor of 38.7 (38.7 to display 0.1 gal; 387 for whole gal.)
Under count, set dploc to dplo.c to read tenths of gallons.
Set PRE A at 55.0; Wire Relay A to solenoid valve.
Conveyer Batching: You want to batch the amount of conveyer distance in feet. An inductive proximity sensor is
used to sense a gear on a conveyer. The gear has 15 teeth (15 pulses per revolution). Each
revolution of the gear equals 3 feet of conveyer movement. To find the number of pulses per
foot, simply divide "15 pulse" by "3 feet" (15 ÷ 3 = 5).
Solution - There's 5 pulses/foot, enter 5 as the scale factor and the display will read in feet.
Set PRE A for the number of feet desired.
Wire Relay A to the conveyer RUN control.
