CUB4L AND CUB4L8 LOW SPEED COUNT INPUT, 30 Hz MAX.
Pulling the “L.S. CNT.” Input to Common
with a mechanical or solid-state switch
increments the counter. The low pass filter used
with a Schmidt trigger circuit debounces
mechanical switch signals. The switch load is
14 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.
WIRING CONNECTIONS
The electrical connections are made via rear screw-clamp terminals located
on the back of the unit. When wiring the unit, use the label to identify the wire
position with the proper function. All conductors should meet voltage and
current ratings for each terminal. Also cabling should conform to appropriate
standards of good installation, local codes and regulations. It is recommended
that power supplied to the unit (AC or DC) be protected by a fuse or circuit
breaker. Strip the wire, leaving approximately 1/4" bare wire exposed
(stranded
wires should be tinned with solder)
. Insert the wire into the screw-clamp
terminal and tighten down the screw until the wire is clamped tightly. Each
terminal can accept up to two #14 AWG wires.
Note: The Reflective CUB4 will
NOT
have a screw terminal installed at the V+
terminal, since it is
NOT
required for operation and is not internally
connected. Refer to the Ordering Information for the part number of a
reflective model that will accommodate the MLPS.
Backlight Wiring
Optional backlight versions of the CUB4 require an external 9-28 VDC
power supply. The external supply is connected between the V+ and Common
terminals.
Warning:
Lithium battery may explode if incinerated.
Caution
: All leads will be at the same line potential as the input leads.
CUB4L8W L.S. INPUT, 30 CPS MAX.
The CUB4L8W 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.
CUB4L HIGH SPEED COUNT INPUT, 5 KHz MAX.
The
“H.S. CNT.”
Input allows the CUB
Counter to operate at speeds up to 5 KHz
when driven by bi-polar outputs. Input drive
voltage must be limited to 28.0 V maximum
to avoid damage to the counter.
