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 k impedance, 10 kHz max. speed.
3M: Mag. Input, accepts 30mV input (50 V max.) signals 10 K
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.
