Delay timer for motor or pump/ 120Volt to 240Volt

Motor delay timer
For 120-240V cut blue jumper wire located on front of timer between terminals
Adjustments less than 30 seconds might not be possible
2" x 2" size
Start motor or pump with delay 1.8 second to 10 minute
Time delay begins when power is applied to input. After delay, load turns ON and stays ON until power is turned OFF.

2 motor delay timer
For 120-240V cut blue jumper wire located on front of timer between terminals
Adjustments less than 30 seconds might not be possible
Turn on 2nd motor after another motor starts
Turn on pump after another pump starts
Turn on 1 motor before another motor
120Volt or 240Volt

In-line fuse protects on-delay timer

Load 1 Turns ON when switch or timer turns ON.
Load 2 turns ON after delay

Reason for this system might be to reduct initial load on circuit so motors do not pull starting amps at same time.
Another reason is that one pump feeds water to second pump. Second pump should not start until water arrives from first pump.

ON Delay
Illustration shows ON delay wiring.
On delay means the load turns ON after delay period expires. Load remains ON until power is off.
Example uses ST01 timer as switch. (Or use Ei600... same timer except 5-year warranty)

ST01 Timer can be set for dusk-dawn. Automatically turns lights ON at night, and off at dusk.
ST01 Timer automatically adjusts for seasonal changes.
ST01 Timer can be adjusted 20 minutes longer or shorter than actual dusk-dawn

However some folks want longer delay before lights turn ON at night
How it works:
ST01 Timer turns ON. AH3 timer receives power. Time delay countdown begins.
After delay period expires, light turns ON, and remains ON until ST01 timer turns OFF
Cycle repeats next time the ST01 timer turns ON.

One-shot timer

Precise digital control
Set mode for one-shot
For on delay: Apply power to terminals 9-10, and normally closed terminal 6 remains OFF until time expires. and then terminal 6 turns ON until power is cut.
For off delay: Apply power, and normally open terminals turn ON for set time, and then remain off until power is cut and applied again.
This can be operated with a Normally closed push button that applies continuous power to the timer mechanism. When the push button is pushed, it starts the delay time circuit for the set duration of time.
Time durations: .01 seconds to 99hour99 minutes (4.16 days)
Repeasts each time power is applied again.

Connect 120volt Hot and Neutral wires to base as illustrated.
Buy thermostat or bell wire and connect to push buttons as shown
The push buttons receive no voltage or power... do not connect to power source.
Plug timer into base. Choose delay time from .05 seconds to 999 seconds
Push doorbell button. Activates timer.
Timer turns ON and begins countdown.
Pump turns ON and runs until countdown stops. Countdown is off-delay.
When countdown expires, timer turns OFF, pump turns OFF.

Contactor with 240Volt coil

240Volt coil

Start winding pulls more amps than switch can safely handle.
Over time, the switch will fail.
Contactors are rated for heavy amp loads, with expected life of millions of operations
Wire contactor use miniature relay instead of contactor. The wiring is not illustrated, so let me know if you want specific illustration.

Never stand on bare soil, put down dry boards.
Tape tester leads to wood sticks to keep hands away from power.
Use non-contact voltage tester before touching wires.
Never touch or lean into any made of metal.
Remove metal objects from pockets.
Do not use oxygen or fuel accelerants in same room as electrical repairs
