Introduction
The Veeder-Root brand C346 family offers a new level of performance in a 1/16 DIN
instrument. Fully programmable to operate as a preset counter, a rate meter (with
outputs) or an elapsed time counter. Enhanced fuctionality provides operating
modes for batching, background totalizing, and operation as dual counters with
master sum. When used as an elapsed time counter, the C346 offers unique
functionality for measurement of pulse widths or time between pulses. The C346 is
available with an LCD display or the industry's only 6 digit LED display for a 48mm
x 48mm product.
A wide variety of features are present that enable use in even the most demanding
applications. Inputs can be accepted from both NPN or PNP sensors, dry contacts or
encoders, and the input scaling function enables rate and count inputs to be
displayed in engineering units. Single and dual preset models are available and
each preset offers both a transistor output, which can interface to an external SSR
or PLC, and a relay output for
directly driving a load. The outputs
can be programmed for latching or
timed operation.
Even with a high level of
functionality, simplicity of operation
is still maintained. Important
parameters such as the preset and
prescale values can be called up
quickly with direct access keys
while an intuitive button per digit
interface enables those values to be changed easily.
The C346 has a NEMA 4 rated faceplate is CE approved, and UL and CUL listed.

Place the unit in the panel and slide the included gasket
over the rear of the unit. Make sure the unit is positioned
squarely against the panel and the gasket is not distorted.
Orient the bracket so that the tabs are pointing away from
the panel. Slide the bracket over the unit so that the tabs
catch in the grooves on the housing, and the bracket is as
far forward as possible. Use the panel mount screws to
tighten the bracket until there is a secure seal against the
gasket.
Please note that there are 4 sets of grooves on the housing
so that the bracket can be positioned with the screws on
the top or the side.
The electronic components of the instrument can be
removed from the housing. To do so the bracket must be
loosened and slid back until the release slot on each side is
showing. Place a small screw driver in the release slot and
gently push forward. Repeat the procedure on the release
slot on the other side. The front panel and PCBs should
then be able to be pulled forward out of the housing.

If the functionality has been set to FN3, then the unit will operate as a
totalizer with seperate subtotal registers for input A and input B. To
enter the Program mode, hold down the Edit key and the "5" key during
power-up. Use the Edit key to move from one parameter to the next,
and the "1" key to scroll through the parameter choices. Holding down
the Edit key for 5 seconds will return the unit to Operation mode.

F11 Count Speed: Enables the unit to be set for full speed of 5 kHz (1) or to 30 Hz (0) to provide
debounce filtering for contact inputs.
F12 Static/Dynamic Reset: When set to static reset (0) counting stops on the leading edge of the reset
input and does not resume until the trailing edge. When set to dynamic reset (1) the Count Value is
immediately reset on the leading edge of the reset signal, and will accumulate while the reset signal is
still active.
F20 Front Panel Reset Enable: When active (0), the count value and output(s) can be reset by
simultaneously pressing the "6" and "4" keys. If set to Off (1), reset can only take place through the
remote input, or through the front panel by holding the "6" and "4" keys for 10 seconds (see F29).
