DESCRIPTION

The GEMINI 3300 is an extremely versatile unit that offers the user

flexibility in batch counting applications. The unit features three integrated
counters in one package; a Process Counter, a Batch Counter, and a Totalizing
Counter. The Process Counter is used to monitor the progress of the count
within the Batch. The Process Counter has 2 Presets associated with it, Preset 1
& Preset 2. Preset 1 is typically used as a “slow-down” output in cut-to-length
applications. When the Process Counter reaches Preset 2 or zero (in Reset To
Preset modes)
, the Process Counter will increment or decrement the Batch
Counter and activate Output 2, and Relay 2 (optional). When the Batch Count
equals the Batch Preset or Zero, the Batch output, Output B (Solid-state only),
will activate. The Process and Batch count can be independently programmed
to auto-cycle back to zero (or Preset) or be programmed for manual Reset To
Zero (or Preset) operation. The Totalizing Counter increments for every Process
Count received. It can be used as a running total per shift, day, etc.

The GEMINI 3300 offers a choice of programmable Input Response Modes to

cover bi-directional, anti-coincidence, and quadrature applications. The input
circuitry is switch selectable to accept signals from a wide variety of sources. The
unit may be programmed to register counts on both edges of the input signal thus
providing frequency doubling capability. Several reset cycle modes, along with
the compatibility of count and control inputs to other RLC products, provides
added versatility for both stand-alone and system counter requirements.

There are two ways to reset the count values of the GEMINI 3300. One

method is with the Reset pushbutton or rear terminal which will reset the
counters as selected in the programming of the Reset Button and Terminal
Actuation Modes. The second method is available to provide means to reset
each count individually. This method requires pressing two pushbuttons. First
press and hold the “E” button, then press the “1” button for Process Count, or
the “2” button for Batch Count.

A “Counter Load” feature is provided which allows changing any of the

three count values utilizing the front panel pushbuttons.

The GEMINI 3300 20 mA Current Loop Communications option provides

the capability of two-way serial communications between the GEMINI 3300
and a variety of equipment, such as a printer, remote terminal, programmable

controller, or host computer. The baud rate can be set to 300, 600, 1200, or 2400
baud. The format for transmitted and received data is 1 start bit, 7 data bits, 1
parity bit (odd), and a stop bit. When utilizing an external power supply (30
VDC max)
, up to sixteen units can be installed in the loop, each with an
individual address. When utilizing the Gemini’s 20 mA current source, up to
seven units can be installed in a loop. The Count Values, Presets, and Scale
Factor can be interrogated or changed by sending the proper command codes
and numerical data (if required) to the unit. Other functions, such as resetting
the various counters, can also be performed. Various “Print Options” can be
selected to automatically interrogate the Count Values, Presets, and Scale Factor
by activating the “Print Request” terminal or by sending a “Transmit Per Print
Option”
(P) command.

The construction of the GEMINI 3300 features a metal die-cast bezel offering

maximum durability with a high quality appearance. The sealed front panel bezel
meets NEMA 4/IP65 specifications for wash-down and/or dust when properly
installed. Electrical connections are made via plug-in terminal strips. Clamp-type
pressure plate terminals accept stripped #14 AWG wire without lugs.
