Description of Logic Functions, CR5 models
ON DELAY:
ent for the preset "DELAY" time. If the input signal is interrupted, the timing is reset and starts over with the next signal.
Grounding pin #9 immediately cancels an output in progress and resets the delay timer. The delay timer is restarted when
the inhibit signal is removed, if an input signal is present.
OFF DELAY:
signal has been removed for the preset OFF-DELAY ("HOLD") time. Grounding pin #9 prevents an output from occuring.
If an inhibit input occurs during an output, the output remains "on" for the remainder of the OFF DELAY time.
ON & OFF DELAY:
DELAY ("DELAY") time and the OFF-DELAY ("HOLD") time are independently adjustable within the selected time range.
Momentary grounding of pin #9 during the ON-DELAY period resets the DELAY timer. An inhibit signal which occurs
during an output will allow the output to stay energized for the remainder of the OFF-DELAY time. ON and OFF DELAY
logic is often used in jam and void control, high/low level control, and edge-guiding applications.
ONE-SHOT:
of the duration of the input signal. With the MAXI-AMP programmed for LIGHT operate, the pulse occurs when the input
signal changes from dark to light. In DARK operate, the pulse occurs with a light to dark input transition. Grounding pin
#9 prevents the one-shot from triggering, but does not affect a pulse already under way.
DELAYED ONE-SHOT:
signal. This input starts the adjustable "DELAY" period, after which the output pulses for an adjustable pulse ("HOLD")
time. No further action occurs unless the input is removed and reapplied, beginning a new sequence. Grounding pin #9
during the delay period will cancel the sequence, and no output occurs. This feature is often used for inspection/rejection
control logic. An inhibit signal will not affect a pulse under way.
LIMIT:
an input signal which is longer than the adjustable LIMIT ("HOLD") time will turn the output "off". Removing the input
signal resets the timer. This function is sometimes called "TIME LIMITED ON/OFF", and is useful for energy conservation.
Grounding pin #9 cancels the output. Lifting the inhibit restarts the LIMIT timer, if an input signal is present.
REPEAT CYCLE:
Presence of an input signal triggers an adjustable "DELAY" timer. After the delay, the output energizes for an adjustable
"HOLD" period. If the input remains, the output continues to cycle "on" and "off" at this rate indefinitely. When the signal
is removed, any output in progress completes and then remains "off" until the next signal and DELAY period. Grounding
pin #9 cancels the sequence, but will allow the completion of a "HOLD" period in progress. Lifting the inhibit signal begins
the DELAY period, if an input signal is present.
DELAY AND LATCH:
An input must be present for at least the adjustable "DELAY" time for the output to latch "on". If the input signal is removed
during the timing cycle, the timing is reset. Momentary grounding of pin #9 resets the latch and/or the DELAY timing cycle.
Sustained grounding of pin #9 inhibits any output.
LIMIT AND LATCH:
("HOLD") timer can be reset only by the auxiliary input. An output remains latched "off" until reset by momentarily ground-
ing pin #9. In addition to resetting the timer, grounding pin #9 will hold the output "off", regardless of the state of the
input signal.
ON/OFF:
Grounding pin #9 (AUXILIARY) turns the output "off", regardless of the state of the input signal. This may be accomplished
by closing a switch or relay contact between pins #9 and #1 (common), or by connecting an open collector NPN (current
sinking) output of any external dc device directly to pin #9. NOTE: connect the COMMON of any external dc device to
pin #1 of the MAXI-AMP to establish a voltage reference between the dc supply for the external device and the internal dc
supply of the MAXI-AMP.
AC LATCH:
will latch the output "on". Grounding pin #9 will reset the latch, even if the input signal remains. The output will not re-latch
until the input signal is removed and then reapplied.
DC LATCH:
pin #9 of a dc latch will turn the output "off" regardless of the state of the input signal. If the signal is present when the reset
is removed, the output will immediately latch "on" again.
The output of the LIMIT function follows the action of the input, as it does with the ON/OFF function. However,
ON/OFF operation does not involve timing. The output simply follows the action of the input signal.
The ON DELAY timer keeps the output "off" until the selected LIGHT or DARK signal has been pres-
