RESET MODE & CYCLE SWITCHES

S4 - ON:

ENABLES Front Panel Reset Button

OFF:

DISABLES Front Panel Reset

S5 - ON:

AUTO RST* - Causes counter to automatically
reset either upon reaching the preset count or
after time-out of output as determined by S6.

OFF:

MAN. - Counter will reset only in response to

Front Panel Button

(if ENABLED)

or Remote

Reset (R).

S6 - ON:

T.D. RST* - Causes counter to reset automatically

(with S5 ON)

at end of output time delay.

OFF:

INST* - Causes counter to reset automatically

(with S5 ON)

at instant preset count is reached.

S7 - ON:

LATCH - causes outputs to latch after reaching
preset. Outputs stay ON until manually reset by
Front Panel Button or Remote Reset.

OFF:

T.D. - Allows outputs to respond to normal time

delayed dropout.

S8 - ON:

LG. DLY. - Sets adjustable Time Delay Range to
0.05 - 1 sec.

OFF:

SHT. - Sets adjustable Time Delay to 0.7 - 15

msec.

Remote Reset (R) and Front Panel Reset (if ENABLED)
will always reset the counter regardless of automatic
setup mode used.

MODEL SCP INPUT/OUTPUT CONNECTIONS & PROGRAMMING SWITCHES

TYPICAL APPLICATION CONNECTIONS & SET-UP

A typical length-measuring wind/rewind application involving up/down

counting to accommodate forward and reverse web motion and provision for
remote reset.

RESET CYCLE MODES - SWITCHES S5, 6, 7 & 8

MODE 1 LATCH AT PRESET, MANUAL RESET

Counts from zero, activates and latches outputs ON at

preset. Front panel button (if enabled) or remote reset (Term.
“R”) returns counter to zero and deactivates outputs. Accepts
new count pulses 7.5 µsec after reset is removed.

MODE 2 MOMENTARY OUTPUT AT PRESET, MANUAL RESET

Counts from zero and activates outputs momentarily at

preset. Momentary output time is adjustable from 0.05 to 1
second. Count can proceed upward if not reset, and if count
direction is then reversed, by pulling U/Ddown to B, the outputs will again
reactivate as the count decrements down through preset a second time.
Output activates each time count passes through preset provided time-out
from previous pass has concluded. Front panel reset

(if enabled)

or remote

reset (R) returns the counter to zero and interrupts output if time-out has not
concluded. Unit is ready to accept new counts 7.5 µsec after removal of
reset.

MODE 3 AUTOMATIC CYCLE - RESET & RUN AT PRESET

Counts from zero, activates outputs momentarily at preset

and simultaneously resets counter to zero, ready to accept
new counts for next cycle 7.5 µsec after resetting. Momentary
output time is adjustable from 0.05 to 1 sec. Output ON-time must be less
than time required to count from zero to reset for proper Mode 3 operation.

MODE 4 AUTO. CYCLE - RESET & RUN AFTER TIME-OUT

Counts from zero, activates outputs momentarily at preset.

Counter resets to zero at conclusion of output time-out and is
ready to accept new counts for the next cycle 7.5 µsec after
reset.

MODE 5 AUTO. CYCLE - PRESCALE DIVIDER

Identical to Mode 3 except momentary output time delay

range switched to

“short”

range

(0.7 to 15 msec)

by placing

S8 in OFF position. The shorter time-out allows the SCP to be
used as a pre-scaling divider providing output pulses in excess of 1 KHz to
the input of another counter.
