How to wire On delay timer

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 1.8 second to 10 minute delay

Time delay begins when power is applied to input. After delay, load turns ON and stays ON until power is turned OFF.

Buy 120-240 Volt delay ON:
ICM 102 / 18-240VAC 1.5 amp load
ICM controls
Packard 102 at Amazon

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 1 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 swithc or timer turns ON.
Load 2 turns ON after delay

Reason for this system might be to reduct initial load on circuit so motos 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.

AH3 off delay timerST01 delay timer

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... sme timer with 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 tunrs 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 tim the ST01 timer turns ON.

Elko delay timer

Elko delay timer/ Multiifunction

On-delay, off-delay, repeat cycle, delay on break, pulse generator, latching, single shot
Imput voltage 12V - 240 volt (50-60 Hz)
Indicator lights for power and countown
.1 seconds to 10 days
Terminal S is trigger switch for some functions, install additional switch on a wire that connects to both terminal A1 and S... when the S wire is switched on, it causes the function to begin, such as latching relay or single shot, neither function usesful for the illustration shown on left, or required for ordinary on or off delay.
Caution, fuse required on hot line(s) as illustrated.

Start winding pulls more amps than switch can safely handle.
Over time, the switch will fail.
