DESCRIPTION
The CUB2L8 counter is powered by an internal lithium battery, which will
provide up to 7 years of continuous operation. This counter has an 8-digit LCD
display with 0.30" (7.6 mm) high digits.
This counter uses a CMOS LSI counter circuit chip, mounted on a gold-
plated substrate and electrically connected by ultrasonic wire-bonding. Internal
electrical interface connections use elastomeric contacts to provide a gas-tight,
corrosion resistant connection. Using the latest in micro-electronic assembly
and manufacturing techniques provides units with the reliability and
dependability required for industrial service.
The CUB2L8 is constructed of a rugged die-cast metal case with a clear
viewing window. The sealed front panel meets NEMA 4X/IP65 requirements
for wash-down and/or dusty environments, when properly installed.
SPECIFICATIONS
1. DISPLAY: 8-digit LCD, 0.30" (7.6 mm) high.
2. POWER SOURCE: Internal 3.0 V lithium battery to provide up to 7 years of
continuous operation. Battery life is dependent upon usage. Count and reset
contacts which remain closed for long periods of time will reduce battery life.
3. HIGH SPEED INPUT: 5 KHz from 3.0 V bi-polar output with a 50%
duty cycle.
4. LOW SPEED INPUT: 30 Hz from switch contact or open collector
transistor with a 50% duty cycle.
5. REMOTE RESET: 15 msec min. pulse width (active low) from a 3.0 V bi-
polar output or an open collector transistor or a switch contact to ground.
6. OPERATING TEMPERATURE RANGE: -25° to +75°C
7. CONSTRUCTION: Rugged die-cast metal case with a clear viewing
window. The sealed front panel meets NEMA 4X/IP65 requirements, when
properly installed. Panel gasket and mounting clips included with unit.
8. WEIGHT: 5.1 oz. (145 g)
ELECTRICAL CONNECTIONS
There are certain considerations that should be observed when running the
count and control signal wires. A length of wire can act like an antenna and the
closer it is to a source of electrical noise, the more it becomes susceptible to
that noise.
There are a few rules that should be followed when running these wires.
1. Never run count or control signal wires in the same conduit or raceway with
AC power lines, conductors that feed motors, solenoids, SCR controls,
heaters, etc.
2. Signal wires within enclosures should be routed as far away as possible from
contactors, control relays, transformers, and other electrically “noisy”
components.
3. When shielded wire is used, connect the shield to the common of the CUB
unit, and leave the other end of the shield disconnected and insulated from
machine ground.
4. Mount the CUB2L8 in a panel that is grounded to the machine frame.
MODEL CUB2L8 - MINIATURE ELECTRONIC 8-DIGIT COUNTER
DIMENSIONS & INSTALLATION
Counters should be mounted in a panel grounded to the machine frame.
After cutting the panel opening, slide the panel gasket over the rear of the
counter body to the back of the bezel lip. Then slide counter through the
panel cut-out. Install mounting clips on each side of counter body with
mounting screws. Make sure the side rails of the clips fit into the recesses
in the side of the counter body so that the “Tang Ends” wedge between the
panel opening and body as the screws are tightened.
DIMENSIONS: In inches (mm)
Warning: Lithium battery may explode if incinerated. Signal input voltage
should not exceed 3.0 VDC to prevent damage to the counter.

Selection of desired operating modes is easily done by moving terminal leads in the
Input Connector Body. The Connector body is polarized to prevent incorrect insertion, and
locked in place by the connector latch to avoid accidental disengagement. Connectors are
supplied with the 3 leads installed as shown at right. A spare blue lead is supplied in the
hardware pack.
Removing Terminal: Insert blade of a small
screwdriver into slot of connector body, and
gently push in to disengage the locking
pawl. Pull terminal out.
Inserting Terminal: When inserting into
connector body, make sure the locking pawl
is toward the slot in the body. Push terminal
in until the locking pawl snaps into slot.

APPLICATION FLEXIBILITY VIA RECONNECT OPTIONS
Pulling the “L.S. CNT.” Input to Common with a mechanical or solid-state
switch increments the counter. The low pass filter (1 meg resistor and 0.015
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.
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. Normally open contacts are
recommended for longer battery life and greater noise immunity.
LOW SPEED COUNT INPUT, 30 Hz MAX.
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 KΩor less. Input drive voltage
must be limited to 3.0 V maximum to avoid damage to the counter. Outputs
higher than 3.0 V can be used with an external voltage divider, as shown.
INPUT PULSE EXCURSION LIMITS
VIN (High) = +2.0 V min.; +3.0 V max.
VIL (Low) = +0.5 V max.
Note: The PSMA Power Supply and Interface Module used for powering RLC
sensors with CUB Counters, has proper interface output for direct drive to
“H.S. CNT.”
RESET OPTIONS
Connecting the “RST. EN.” (Reset Enable) Input to Common activates the
front panel Reset button. To deactivate the front panel Reset button, 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 15 msec in Reset response.
HIGH SPEED COUNT INPUT, 5 KHz MAX.
