If you are unfamiliar with basic electrical circuitry, it would be wise to have someone with electrical knowledge personally help you wire the relay. Relays are simple to wire but, if you do not understand the basic principles, you can do damage.

How to connect an omron h3y timer into a circuit


I see your comment to ignore:
To protect timer, read following:

1) Max load on this timer is 5 amp at 240volts
http://waterheatertimer.org/pdf/Omron-H3YN0302.pdf

2) If load exceeds 5 amps, then use timer to control contactor.
Here is crude drawing showing basic wiring for pin timer controlling heavy amp load.

3) If amp rating on incoming wires exceeds 5 amp, for example is circuit breaker feeding circuit is 20-30 amps etc, then protect wires to timer using busman in-line fuseholder with fast-acting 5 amp cartridge fuse.

I need a wiring diagram for an Omron H5CX-A timer


Wiring will appear on side of timer.
Test the timer with multimeter to see which terminals are connected. When timer has no power, then Com and NC terminals will have continuity.
H5CX-A Timer has 11 screw terminal connections and timer is rated 100V to 250Volt AC 50-60Hz.
Input is power IN > this is the 100V to 250Volts coming from breaker box or transformer. For example input terminals might be labeled A and B.
This will give power to timer, but remainder of screw terminals have no power.
To put power to relay terminals, jumper the power from Input terminal A to COM terminal.
For example Com terminals might be 7 and 9.
So jumper Hot wire from Terminal A to terminal 7.
This action will put hot on Com terminal 7, but also give power to the NC terminal.
For example the NC terminals might be 1 and 3.
So when timer is OFF, the NC terminal has power.
Then when timer turns ON, the NC terminal no longer has power, but the NO terminals are Hot.
NO terminals might be 4 and 6, and these terminals turn on-and-off when timer turns on--and-off

I am wanting to energize a relay for 3 min. then off, whether the power stay's on to coil or not! what I want to do is when a door rises and hits a switch I want to energize a coil for 3 min. whether...


You want 3 minute 'off delay' timer.
When timer is energized with push button or momentary electrical signal, circuit remains ON for set amount of time, and then turns OFF.

Most delay timers have 1 amp capacity rating, so circuit needs fast acting 1 amp fuse, and timer controls separate relay or contactor unless Load is equal to 100 watt light bulb.

Farberware Convection Oven T490c does not turn on.


It is usually one of two items that could cause this problem. You need to take the outer shell off. Lots of screws. Pull the "brain board" from the right, front of the oven. There is a relay housing. This 30 amp. relay is made by Omron. Look at the connector pins on the back side of the relay, especially the white wire that goes to the distribution block then on to the heating coil. I find that the soldered pins on the pc board next to the relay often get so hot that they 'shed' the solder. If so, simply clean well and re-solder. The relay itself can also go bad. Unfortunately, I haven't been able to obtain replacements. What I did on one oven was to buy a 30 amp, open frame relay (~$20). Mount it on the chassis near the fan. Remove the Omron relay and simply run the appropriate wires to the open frame relay. That works very well.
