SOURCE: I use Omron H3CR 8pin

I don't have exact schematic for your 8-pin timer.
Use multimeter read ohms and voltage from pin socket to pin socket.
Use multimeter set to ohms to read continuity of pins on timer.
Pin timer relays have NO NC pins.
Some pins are Normally Open (no current flows until timer turns on)
The other pins are Normally Closed (current flows until timer turns on, and when timer turns on, this circuit turns off)

H3CR 11 pin


1) When oven turns ON, Power flows between the timer and the oven.
http://waterheatertimer.org/How-to-wire-pin-timers.html

2) For example the oven might be connected to pins 8 and 1.
Connect a light bulb to terminals 8 and 1.
http://waterheatertimer.org/images/10-pin-wiring-350.jpg

3) Since the H3CR timer is rated max 16 amps, I suspect the timer controls a contactor and is not directly attached to heavy oven wires.
So if max amp load on timer is 16 amps, then it is safe to add light bulb wire without line fuse between timer and light.

Delay timers usually start with a push button, or momentary impulse of power. The delay begins when the impulse power ends.
H3CR-A is solid state multi-functional pin timer available in 8-pin and 11-pin models.
11 pin has six modes, and 8 pin has 4 modes
http://waterheatertimer.org/pdf/OMRON_H3CR-multi-function-analog-sell-sheet.pdf
How many pins do you have?
What exactly are you controlling with the timer?
And what function are you using?

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

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.

How to set the time and which is on out or in


pins IN = timer ON
pins OUT = timer OFF
Slide-switch must be pushed to right for timer to work
If dial is not rotating, wiring is incorrect (see below for wiring)
__________________________________________

Grasslin and Paragon both offer multiple-gang timers.

Grasslin manual says:
" For example, to turn lights ON at 5:00pm and OFF at
11:00pm, leave inward the 18 trippers between 5 and
11 on the "pm" side of the dial.

Link to Grasslin manual

Wiring timer:
Timer black goes to Hot wire
Timer red (or blue) goes to Load
Timer white goes to Neutral (if no neutral, then connect to bare ground)
If timer dial does not rotate, black and red wires are reversed
