Application:
This miniature batcher is ideal for all batching applications. The
display will show Batch Amount, Rate and Batch/Grand Total at the
push of a button. The Start and Stop buttons make batching 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.
Up to 99 units can communicate to a host computer on a single
RS232 or RS422 loop.

Inputs:
3: High Impedance DC pulse input 4-30 VDC (high), Open or 0-
1 VDC (low), 10 ký imp. 10 kHz max. speed.
3M: Mag. Input, accepts 30mV input (50 V max.) signals 10 Ký
imp. 5 kHz max.
Stop / Reset:
Front Panel:
STOP/RST button stops batch if batch is running, Resets dis-
played 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.
Start:
Front Panel:
START button Starts batch by energizing Relay A (and Relay B if
Prewarn selected).
Remote:
4-30 VDC, positive edge: Starts batch by energizing Relay A (and
Relay B if Prewarn selected).
Scaling Factor
(K-Factor)
:
A user programmable K-Factor is used
to convert the input pulses to engineer ing units. The 5 digit K-
Factor divider, with decimal k eyed 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
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.
Control Outputs:
Relays:
2 each N.O. Relay; 10 Amps 120/240 VAC or 28 VDC. (N.C.
relay contacts and NPN transistor output available with solder
jumpers. Transistor output is internally pulled up to 10 VDC
through relay coil, sinks from 10 VDC to 0.5 V @ 100 mA)
Analog Output:
An optional 4-20mA (0-20mA) output is available for the Mini-
Batch 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.
