Inverted Delay-on-Break
(Pulse Former, One Shot Relay, Single Shot Interval, Pulse Shaping)
OPERATION: Input voltage must be applied before and during timing. Upon momentary or maintained
closure of the initiate switch, the output (relay or solid state) energizes and the time delay begins. At
the end of the delay, the output de-energizes. Opening or reclosing the initiate switch during timing
has no effect on the time delay. Note (for most single shot timers): If the initiate switch is closed when
input voltage is applied, the output energizes and the time delay begins.
RESET: Reset occurs when the time delay is complete and the initiate switch is opened. Removing input
voltage resets the time delay and output.

Extra Functions Included in Some Single Shot Timers:
Instantaneous Contacts:
Some Single Shot timers have a set of instantaneous contacts in addition to the delayed contacts.
Instantaneous contacts energize when input voltage is applied and remain until voltage is removed.

OPERATION: Input voltage must be applied prior to and during timing. The output (relay or solid state)
is de-energized. When the initiate switch S1 closes momentarily or maintained, the output energizes
and the time delay begins. Upon completion of the delay, the output de-energizes.
RESET: Reclosing S1 resets the time delay and restarts timing. Removing input voltage resets the time
delay and output.

Function US)
OPERATION: Input voltage must be applied before and during timing. Upon momentary or
maintained closure of the initiate switch S1, the output (relay or solid state) de-energizes. At the
end of the time delay, the output energizes. Opening or reclosing S1 during timing has no affect on
the time delay. The output will remain de-energized if S1 is closed when input voltage is applied.
RESET: Reset occurs when the time delay is complete and S1 is open. Removing input voltage resets
the time delay and output.

Function PSE)
Trailing Edge Single Shot (Impulse-OFF): (ProgramaCube
®
Function TS)
OPERATION: Input voltage must be applied before and during timing. When the initiate switch
S1 opens, the output (relay or solid state) energizes. At the end of the time delay, the output
de-energizes. Reclosing and opening S1 during timing has no affect on the time delay. The output will
not energize if S1 is open when input voltage is applied.
RESET: Reset occurs when the time delay is complete and S1 is closed. Removing input voltage resets
the time delay and output.See: HRPS, KRPS, KSPS, KSPU, NHPU, TRDU
OPERATION: Similar to retriggerable single shot function PSD above except, when input voltage is applied,
the output (relay or solid state) immediately energizes and timing begins. At the end of the time delay, the
output de-energizes. The unit will timeout as long as S1 remains open or closed for a full time delay period.
RESET: During timing, reclosing S1 resets and restarts the time delay and the output remains energized.
After timeout, reclosing S1 starts a new operation. Removing input voltage resets the time delay and
the output.
