Pulling the “L.S. CNT.” Input to Common with a mechanical or solid-state
switch increments the counter. The low pass filter (2.2 M
Ω
resistor and 0.0068
µf capacitor) used with a Schmidt trigger circuit debounces mechanical switch
signals. The switch load is 6 µA (max. voltage drop 0.5 V) when ON. The
OFF-state leakage current must be less than 2 µA.
Motor starter contacts, tungsten contacts, and brush-type contacts should
not be used.
The “H.S. CNT.” Input allows the CUB70 to operate at speeds up to 10 KHz
when driven by bi-polar outputs or external circuits having an output
impedance of 3.3 K
Ω
or less. Input drive voltage must be limited to 3 V
maximum to avoid damage to the counter. CMOS and TTL Logic outputs can
be loaded with a resistor (R
L
) to limit drive voltage, or a voltage divider can
be used as shown for the PNP O.C. Transistor output.
Note: The PSMA Power Supply and Interface Module
used for powering RLC sensors with CUB
Counters, has the proper interface output for direct
drive to the H.S. CNT.

Notes:
1. Burst to DC backlight power had a power line filter installed RLC
#LFIL0000 or equivalent at the unit.
2. Self-recoverable loss of performance during EMI disturbance at 10 V/rms
to backlight power lines.
LCD segments may flicker during EMI disturbance.
For operation without loss of performance:
Install power line filter RLC #LFIL0000 or equivalent at the unit.
Refer to the EMC Installation Guidelines section of this bulletin for
additional information.

CUB7W L. S. INPUT, 30 CPS MAX.
The CUB7W accepts most machine control voltage signals. The input
accepts AC (50/60 Hz) or DC control voltages from 10 to 300 V at count
speeds up to 30 cps. The unit counts on the positive going edge of the input
signal.
WARNING
: Any lead may be at hazardous live input potential.
External wiring and devices connected to the unit must be
rated the same as applied signal input voltage and be
properly isolated from Class 2 or SELV circuitry.
