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 alter-
nately. 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 flex-
ing. 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 standard. 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 Industrial Customer
Service.

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 de-
signed 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 energized
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 fol-
lows:
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 ap-
pear. Press ENTER. The present Preset B will appear.
Press buttons "A" through "E" to load in desired 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 energize and
the right decimal will light. The unit will count in engi-
neering 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.

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.
