Instruction manual

Timing Charts, Cat. No. 700-HT3 Multi-Function Time
Module (t = Time Range 0.05 s…100 h)
Terms:
U is Power Input
R is Relay Output
S Signal, +A1 Socket, B1 Timer
t is the resulting Time Delay (Red LED)
1. Power On-Delay
Apply power (U) to timer. Relay contacts (R) change state after time
delay (t) is complete. Contacts return to their shelf state when power
is removed. Terminal B1 is not used in this mode.
2. Power On One-Shot
Apply power (U) to timer. Relay contacts (R) change state
immediately and the time delay begins. When the time delay (t) is
complete, contacts return to their shelf state. Contacts return to
their shelf state when power is removed. Terminal B1 is not used in
this mode.
3. Power On Repeat Cycle, On Start
Apply power (U) to timer. Relay contacts (R) change state
immediately and the time delay (t) begins. When the time delay is
complete, the contacts return to their shelf state for time delay (t)
(time on = time off). This cycle will repeat until the power is
removed. Terminal B1 is not used in this mode.
4. Signal On-Delay and Signal Off-Delay
Apply power (U) to timer. When the signal (S) is closed the time
delay (t) begins, after the time delay is complete the relay contacts
(R) change state. Opening the signal starts the time delay, after the
time delay is complete the contacts return to their shelf state. If the
signal is closed or opened before the time delay is complete, the
time delay is reset. Contacts return to their shelf state when power
is removed.

5. Signal Off-Delay
Apply power (U) to timer. When the signal (S) is closed, the relay
contacts (R) change state immediately. When the signal is opened,
the time delay (t) begins. If the signal is closed before the time delay
is complete, the time delay is reset and the relay remains energized.
When the time delay is complete, the contacts return to their shelf
state. Contacts return to their shelf state when power is removed.
6. Signal On One-Shot
Apply power (U) to timer. When the signal (S) is closed, the relay
contacts (R) change state immediately and the time delay (t) begins.
After the time delay begins, opening or closing the signal will not
reset the time delay. When the time delay is complete, the contacts
return to their shelf state. Contacts return to their shelf state when
power is removed.
7. Signal Off One-Shot
Apply power (U) to timer. When the signal (S) is closed and then
opened, the relay contacts (R) change state immediately and the
time delay (t) begins. After the time delay begins, opening or closing
the signal will not reset the time delay. When the time delay is
complete, the contacts return to their shelf state. Contacts return to
their shelf state when power is removed.
8. Signal On and Signal Off Watchdog Monitor
Apply power (U) to timer. When the signal (S) is closed, the relay
contacts (R) energize immediately and the time delay (t) begins. If
the signal is opened before the time delay is complete, the relay
remains energized and the time delay is reset. When the time delay
is complete the contacts return to their shelf state. If the signal is
opened after the time delay is complete, the relay contacts energize
immediately and the same time delay begins. Continuous cycling of
the signal at a rate that is faster than the time delay will cause the
relay contacts to remain energized. Contacts return to their shelf
state when power is removed.
