Time delay wiring

[timlkallam]

I have a small gear moter i need to run for 30 seconds when I push the start button I want it run for 30 seconds and turn off .I bought a Macromatic off delay unit. Well I tried to wire it up but I don't understand the wiring diagram. I understand the switch and the power input but how do I connect the small 120 volt motor. Hears a wiring diagram with numbers. How do I conect the motor.
Thanks for any help.

I believe you want a delay on operate, not delay on off for your app.
Use either or both of the isolated relay contacts to switch the power to the motor.
Depending on what the motor power is, the can be fed from the power terminals, or if different voltage then a separate supply.

Hi Tim

What is the switch model number? I don't see the jpegs as they are still marked as pending approval. Macramatic delay switches usually have either 20 v DC or mains input to trigger the delay period. The operation should be simple ( as per Al's post) - press button applys trigger voltage for a fraction of a second - timer activates and the internal relay is energised i.e. the normally open contacts close for the delay period. If you get the no and nc mixed up the motor will run all the time but on pressing the button will switch off for the preset period. Point to note is do not play with the delay setting on the switch whilst it is energised if you have the pug in type with the select delay control.

Post the switch part number if you need further help.

Regards

If it is an off delay, closing 5&6 will energize and it will remain energized until you remove 5&6 and then it will time out, time delay on closure is time delay on operate, i.e on when 5&6 closed and time delay starts immediately.
You can get timers like this that can be configured to the timer pattern you require.

I am sorry to hear you have had a little trouble connecting our time delay relay. Here is how I would personally recommend connecting it:
(This assumes that the relay coil and motor both run from the same power source.)

Connect 120V Hot to relay pin 2
Connect 120V Nuetral to relay pin 10
Connect the two terminals of your pushbutton switch directly to relay pins 5 and 6, no specific polarity is required.
Connect relay pins 2 and 1 together using a wire(jumper).
Connect the hot lead from the motor to relay pin 3
Connect the Nuetral lead from your motor to Nuetral(this can be done at pin 10 if desired)

When you are wiring to the plugin socket, observe that the pin numbers are printed in the plastic. Make sure to reference these numbers so you do not wire the product backwards. The wiring diagram of the relay itself is a mirror image of the wiring socket.

Please always follow all applicable electrical safety practices; Macromatic always recommends use of a licensed electrician or other qualified professional for installation and verification.
