RESET AND PROGRAM OPTIONS
Connecting a wire from the RST EN (Reset Enable) or the HS (Program
Enable) Input terminals to Common will enable the front panel Reset or
Program buttons respectively.
Pulling the “RST.” input low causes the counter to reset. The “RST.” can be
pulled low by either a mechanical switch or solid-state transistor switch. The
Switch load is 15 µA (max. voltage drop 0.5 V) when ON. The OFF-state
leakage current must be less than 2 µA.
Note: The RC protection circuit on the “RST.” Input causes a delay of
approximately 15 msec in Reset response.
L.S. INPUT; VOLTAGE VERSIONS (30 Hz MAX.)
The CUB7P accepts most machine control voltage signals. The input
accepts single phase AC (50/60 Hz) or DC control voltages from 10 to 300 V
at count speeds up to 30 Hz.. The counter increments when voltage is applied
between the LS input and Common.
Any off-state leakage current may prevent
the counter from operating properly.
WARNING
: If voltage input is connected to circuits above 30 Vrms,
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.
L.S. INPUT; CONTACT VERSIONS (30 Hz MAX.)
Connecting the “L.S.” Input to Common with a mechanical or solid-state
switch increments the counter. The switch load is 7
µ
A (max. voltage drop 0.5
V) when ON. The OFF-state leakage current must be less than 2
µ
A.
Reed switches, mercury wetted contacts, snap action limit switches, and
silver alloy relay contacts with wiping action are usually satisfactory for input
activation. Motor starter contacts, tungsten contacts, and brush-type contacts
should not be used.
