Delay-on-Make: (ProgramaCube
®
Function M)
(ON-delay, Delay on Operate, On Delay, Operate Delay, Delay On, Prepurge Delay)
OPERATION: Upon application of input voltage, the time delay begins. The output (relay or solid state)
is de-energized before and during the time delay. At the end of the time delay, the output energizes
and remains energized until input voltage is removed.
RESET: Removing input voltage resets the time delay and output.
See: HRPS, KRPS, KSPS, KSPU, NHPS, NHPU, TDM, TRDU
Extra Functions Included in Some Delay-on-Make (DOM) Timers:
Accumulating Time Delay Feature: (ProgramaCube
®
Function AM)
Some DOM timers allow the time delay to be stopped and held and then resumed by opening and closing
an external switch. The total time delay, TD is the sum of the accumulated partial time delays, “t”.
See: KRPD, KRPS, HRPS, NHPS, KSPD, KSPS, TRDU
Instantaneous Contacts:
Some DOM 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.
Delay-on-Make, Normally Closed Output:
All relay output delay-on-make timers with normally closed contacts include this function. (See Delay-
on-Make NC Contacts) This function is also available in solid-state output timers. The solid-state output
energizes when input voltage is applied. The time delay begins when an optional initiate switch S1 is closed
(timing starts when voltage is applied if S1 is not used). The output de-energizes at the end of the time delay.
Reset: Opening S1 resets the time delay and the output immediately energizes (or remains energized).
Removing input voltage resets the time delay and de-energizes the output.

OPERATION: Upon application of input voltage, the time delay begins. The output (relay or solid
state) energizes during the time delay. At the end of time delay the output de-energizes and remains
de-energized until input voltage is removed.
RESET: Removing input voltage resets the time delay and output.
See: HRPS, KRPS, KSPS, KSPU, NHPS, NHPU, TDI, TSD2
Extra Functions Included on Some Interval Timers:
Instantaneous Contacts:
Some Interval timers have a set of intantaneous contacts in addition to the delayed contacts.
Intantaneous contacts energize when input voltage is applied and remain until voltage is removed.
