CUB 1 MINIATURE
ELECTRONIC COUNTER

CUB 2 GENERAL PURPOSE
INDUSTRIAL COUNTER

GENERAL DESCRIPTION

SELF POWERED

Self-Contained batteries eliminate the need for external power and prevent
loss of count if power fails. Also provides for remote or portable applications.
Battery operation also means elimination of shock hazard and allows the use of
2-conductor bell wire for count signals and micro-power input signals.

Batteries are easily replaceable (2 “N” Cells, alkaline) and average battery
life is four years.

FLEXIBILITY

Various count inputs allow use with switch contacts or high speed pulse
outputs from electronic sensors and circuits. The reset function can be disabled,
set up for front panel reset, remote reset, or both.

NO-WEAR, NO-NOISE

The CUB’s micro-circuits can accurately and silently accumulate enough
counts in one hour to completely wear out an ordinary E.M. counter. More over,
it can repeat this performance many times with just one set of batteries.

RELIABILITY

Internal “micro-assembly” construction withstands many times the “g” force
of shock and vibration compared to conventional construction.

CUB counters also feature elastomeric contacts. This eliminates long term
problems associated with contact corrosion.

Battery operation, a high degree of input filtering, plus an inherent common
mode rejection ratio of more than 120 dB @ 50/60 Hz, provides ultra-high
immunity from electrical noise interference.

SPECIFICATIONS

1. DISPLAY: 6-digit LCD
CUB 1: 0.2" (5 mm) high
CUB 2: 0.35" (9 mm) high

2. POWER SOURCE: No external power required. Operates from 2 “N” type
alkaline batteries (supplied separately). Battery life up to 4 years. (See Note

below.)

3. COUNT & RESET INPUT SIGNALS: Adapts to Count-Switch Contact
Signals, Open-Collector Transistor Outputs, and Bi-Polar Drive Outputs as
shown in the diagrams on the following page. Counter increments and resets
on negative going (pull down) transition of count or reset signal.

4. ENVIRONMENTAL CONDITIONS:

Storage Temperature Range: -20° to 60°C (-4° to 140°F)
Operating Temperature Range: 0° to 50°C (32° to 122°F)
Vibration to IEC 68-2-6: Operational 5 to 500 Hz, 5 g.
Shock to IEC 68-2-27: Operational 30 g.

5. COUNT SPEED: Up to 50 Hz with switch contact input (counters have
internal de-bounce circuits) or up to 5 KHz with solid-state electronic input
(See diagrams on following page).

6. CONSTRUCTION: Rugged die-cast metal case with clear viewing window.
The sealed front panel meets NEMA 4X/IP65 requirements when properly
installed. Panel gasket and mounting clips included.

7. WEIGHT:

CUB 1: 4.0 oz (113.4 g)
CUB 2: 5.2 oz (147.4 g)

Note: When using switch contacts for count input or remote reset, normally

open contact circuits are recommended. Switch contacts that remain
normally-closed and are opened only briefly to signal a count, can reduce
battery life to somewhat less than 4 years.

USE CUB COUNTERS WITH:

VCM • VOLTAGE CONVERTER MODULES for isolated, A.C., control voltage count inputs to 270 VAC,

LCM • LOGIC CONVERTER MODULES for interface with standard logic voltages & outputs

Selection of desired operating modes is easily done by adding or moving
terminal leads in the Input Connector Body. The connector body is polarized to
prevent incorrect insertion, and locked in place by the battery cover to avoid
accidental disengagement. Connectors are supplied with the 3 leads installed as
shown below. A spare blue lead is supplied in the hardware pack.
TO REMOVE TERMINAL, insert blade of a small screwdriver into slot of

connector body, and gently push in to disengage lock pawl. Pull terminal out.
WHEN INSERTING TERMINAL into connector body, make sure the lock

pawl is toward the slot in the body. Push terminal in until lock pawl snaps

into slot.

Pulling the L.S. CNT. Input to Common with a mechanical or solid-state
switch increments the counter. The low pass filter (1meg resistor and 4700
pf cap) used with a Schmidt trigger circuit debounces mechanical switch
signals. The switch load is 14 µA (max. voltage drop 0.5 V) when ON. OFF-
state leakage current must be less than 2 µA.

Moving the white wire to the H.S. CNT. Input allows the CUB Counter to
operate at speeds up to 5 KHz when driven by bi-polar outputs or external
circuits having an output impedance of 3.3 KΩ or less. Input drive voltage
must be limited to 3.0 V maximum to avoid a charging current into the
batteries which can cause premature battery failure or leakage. CMOS and
TTL Logic outputs can be loaded with a resistor (Rl) to limit drive voltage,
or a voltage divider can be used as shown for the PNP O.C. Transistor output.

Reed switches, mercury wetted contacts, snap action limit switches, and
silver alloy relay contacts with wiping action are usually satisfactory for
generating count input signals. Motor starter contacts, tungsten contacts, and
brush-type contacts should NOT be used.

Note: By parallel connecting both H.S. CNT. and L.S. CNT. inputs, count

speed can be increased to 250 Hz if de-bounce is not needed.

Connecting the RST. EN. (Reset Enable) Input to Common activates the
front panel Reset button. When the front panel Reset button is to be
de-activated, remove the yellow wire from the RST. EN. Input.

When Remote Reset is required, the blue wire in the hardware pack is
inserted in the REM. RST. Input. Pulling this input low causes the counter to
reset. The REM. RST. can be pulled low by either a mechanical switch or
solid-state transistor switch. Switch load and leakage are the same as for L.S.
CNT. Input above.

Note: The RC protection circuit on the REM. RST. Input causes a delay of

approximately 6 msec in Reset response.
