Relay advice anyone check this wiring diagrams for me

This is for techies only
 
Both switches are DPDT
13&14 are the live/neutral for switching the relay on/off
1&5 are the input to switch
5&8 are the NO contacts
9&12 are the NC contacts
 
 
*****These diagrams are wrong look down 2 posts******
This one simply turns a pump for drainage on/off depending on the position of the float on a user set delay (0-30 mins)

This is the more complex but smarter circuit

This one also turns the dripper pump off when the float switch is triggered and keeps the pump off for 1 hour.
 
The dripper pump is controlled by a timer AND relay! The drain is constant live AND relay the switch is the float switch. You run the drippers on maximum of 1 hour on at a time.
 
The first circuit is perfect for recirculation but wasteful for DTW, the 2nd one works for both recirculation and DTW and is easily adjustable if needed to control the amount of run off.
 
the 2nd circuit reduces the amount of nutrients wasted in DTW essentially and is user adjustable.
 
I'm only offering 1st circuit style recirculation pods at the moment but 2nd circuit type will be an optional extra (it will add 40% to the cost of each recirculation pod) soon once I've ironed the bugs out of it and throughly tested it for 1 grow.
 
I'm 99% sure the first circuit is correct
 
the 2nd circuit only 95% sure took me all yesterday to work the 2nd circuit out
 
I will H3Y-2 (0-30 minutes) relay and ST3PF (60mins)
 
H3y-2 is a time delay relay, ST3PF is a power off delay relay
 
Thanks

link the manuals for the timers you are using. 
 
are you sure that terminals 5 and 9 will power the units? in most cases, these relay contacts will NOT hand off power from the main leads, but rather act as switches.
 
what pump are you using for a "dripper pump"?

aslso in the future you should do wiring diagrams with a ladder, its far easier to read.

It's my first wiring diagram :) It's also the 2nd time I've ever used Draw.
 
Unsure what pumps we will use but under 30w @230v at maximum
 
You're right I'm being retarded ha ha ha I was arse about tit lol in my defence it's been 4 years since I last wired a relay up :)
 
13/14 are the switch current
1&5 are the NC contacts
5&9 are the NO contacts
9&12 are the load

the first diagram should look like this

Did you try wiring the dripper pump to the flux capacitor?
 
I did but unfortunately I used a Delorean and as we all know the chances of one actually getting to 88MPH is nil lol.
 
I checked the dripper pump is ~10w and the drainage pump is 3.4w both relays have 5a contacts.
 
This is my last relay project a bit less professional :) this was 4 years ago though.

This controlled co2 and turned the solenoid off when the fans were running.

what are those circular deals? fire alarms?
 
Junction boxes (only 1 is used) they're just fancy connector blocks for wiring common and cheap in the UK ~50c each.

I will put all this in a IP55 rated enclosure with IP68 glands instead of on a piece of ply ha ha ha and I will use a more suitable connector I had junction boxes and ply to hand when I made that.
