simple.

Description:

The MINI-Batcher is a 6 digit totalizer and 4.5 digit ratemeter with
two relay outputs. One output is dedicated to the batch amount
(Preset A), the other can be activated for Prewarn or Batch/Grand
Total. The unit can count up to the preset (reset to 0) or down from
the preset (set to preset). Start, Stop and Reset functions can be
activated from the front panel or remote inputs.
An analog output (assignable for Rate or Batch Amount) is avail­able for data logging.
Several units can communicate to a host computer on a single
RS232 or RS422 loop.

• 30mV Magnetic Pickup Input Option

• 4-20mA or 0-20mA Analog Output Option

Inputs:

3: High Impedance DC pulse input 4-30 VDC (high), Open or

0-1 VDC (low), 10 kΩ impedance, 10 kHz max. speed.

3M: Mag. Input, accepts 30mV input (50 V max.) signals 10 KΩ

imp. 5 kHz max.

Stop / Reset:

Front Panel:

STOP/RST button stops batch if batch is running, Resets dis­played value and control output if batch is stopped.

Remote:

4-30 VDC, positive edge: stops batch if batch is running, Re­sets batch amount if batch is stopped.

NOTE: Hold either front or remote reset active to inhibit any start

inputs.
Scaling Factor (K-Factor): A user programmable K-Factor is
used to convert the input pulses to engineering units. The 5 digit
K-Factor divider, with decimal keyed into any position, allows
easy direct entry of any K-Factor from 0.0001 to 99999.
Presets: Two control outputs are provided. A 5 digit value can
be entered for both presets. The decimal point location is the
same as the counter (No decimal in Batch Total counter).
PRESET A:

The preset A output is dedicated to the batch amount. When
ST ART is activated, Relay A will energize and remain on until
the batch is complete or the batch is stopped.

PRESET B:

The preset B output can be programmed to activate as a
Prewarn (for two stage batch control) or activate on Batch
Total (number of batches) 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 (number of batches) or Grand T otal,
Relay B will activate when the batch total or grand 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 (number of batches) or grand total will auto-reset
at preset B.

Control Outputs:

Relays:

2 each N.O. Relay; 5 Amps 120/240 VAC or 28 VDC. (N.C.
relay contacts and NPN transistor output available with solder
jumpers.

Analog Output:

An optional 4-20mA (0-20mA) output is available for the Mini­Batch series. The output can be programmed to track rate or
batch amount. Connections are via a 2 terminal pluggable
screw connector. Programming is accomplished by using the
front panel in conjunction with rear dip switches. Accuracy:
±.25% FS worst case. Compliance Voltage: 3 to 30 VDC non

inductive.
Lockout: Unauthorized front panel changes can be prevented
by entering a user selected 5 digit code. The front panel can be
completely locked out (except Start & Stop) or the preset can
remain accessible.
Ratemeter: Accuracy: 0.01% FS (±1 display digit).
The rate display updates once per second. The rate meter can
be programmed to sample from 2 to 24 seconds maximum, and
auto-range up to 5 digits of significant information. The ratemeter
displays in units per second, minute or hour.
Batch or Grand Totalizer: In addition to viewing the batch
amount, a second counter can be viewed. This counter is pro-

grammable to count either the number of batches (Batch Total)
or the grand total count (Grand Total).

RS232/RS422 with KEP Protocol:

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 loop.) Unit status and new set
points can be communicated by serial communication. Mode
changes, however, must always be made on the front panel.
Data is received and transmitted over standard EIA RS232 or
RS422 levels. Unit number, baud rate and parity are entered in
the “Program Setting” set up mode and remain in memory even if
power is off.

RS232/RS422/RS485 with Modbus RTU Protocol:

The serial port can be used for serial printing or also for data
acquisition. The unit can address up to 247 units (The terminal
addressing the unit must be capable of driving all loads in the
loop.) The unit can communicate with a master device through a
Modbus-RTU protocol. The data given for each parameter is in
IEEE float format comprising of 2 words. The unit can be
connected in a network.
