RESET OPTIONS
Connecting a wire from the
“RST. EN.” (Reset Enable)
Input terminal to
Common will enable the front panel Reset button. When Remote Reset is
required, a wire is connected from the “
REM. RST.”
input terminal to
Common. 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.
BACKLIGHT OPTION
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 as shown in the drawing.
Red Lion Controls optional power supply (MLPS1000) is designed to be
attached directly to the rear of a CUB4 and is powered from a 85 to 250 VAC
source. The MLPS provides power for unit backlighting and a sensor.
WARNING
: When connecting the wiring for a backlit CUB4L8W
measuring an AC input voltage, the neutral of the single phase AC
signal is connected to Terminal 1 (COM), and line (hot) is
connected to Terminal 5 (LS). The DC supply for the backlighting
is connected as shown in the drawing. Three phase AC applications
require an isolation transformer.
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 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 (Rl) to limit drive voltage, or a voltage divider can
be used as shown for the PNP O.C. transistor output.
