Electric Brewery Build UK Version

[barneey]

I`ve only got a couple of spare 22mm 240v buzzers

[Belter]

So have I I need 24v. Damn.

The B3S one Clive and I have and also the B1 mechanical version Clive has are both linked on I think page 17. There are pros and cons with both.

The timer was £22. So was the pid. I'll dig out my link in a min couldn't find one cheaper.

Edit: This is the PiD. http://item.mobileweb.ebay.co.uk/viewit ... 0976913531

Make sure when you order you message them saying you want D1S-VR-220.

This is the timer I have:

Barney has the B1S. And I think I've just found a better one. B2S. It's digital but has a reset button facility. I'll look into it later. Basically depends on what you need it to do.

Just a couple of questions regarding the timer

Am I right in thinking you need a start and stop but or is that an option ?

Does the timer count up or down ?

Can you fit an alarm to shown the end of the 90 min cycle time

Thanks in advance

Lee

A stop & start button is a must.

The timer counts down.

Yes the alarm can be made to activate at the end of a cycle.

I might need a diagram at some point I have one on order should be here soon I hope

These timers do have wiring diagrams in the instructions but if you want a look in advance then they are online under downloads:

I haven't played enough with it yet but my timer counts down in option A. Then up in option C. So... C always needs to be set for like 10 hours or the timer will go back to 0. Not a major problem but as mine starts my panel in the middle of the night I need to make sure option C is long enough ao the pabek doesn't switch off again.

The stop button seems to do the same as the reset button on the front so if you don't have space for another button then you can just have a start button.

Or you can do like Clive and I have done and get a combined start stop button that only uses 1x 22mm hole. Cheers for the headshot on that Clive.

To make the alarm activate at the end of the cycle you need to wire the output into your Alarm circuit.
Did you want to use it just as an alarm?

Hi Lee,

I am only looking to use this on a count down basis and a the end of the cycle time turn on a panel light. Quite simple but is all I need. I'm not looking to use this to turn the brewery on in the middle of the night.

Cool then you can wire your alarm into output C and set it for an alarm period 1s to 99hours. You need to power the timer and loop the supply to the common contact on output c. Then take the Normally open contact on output C to the alarm Light. The circuit diagram and numbers for each contact are displayed on the side of the timer. Very handy.

[barneey]

Yep sorry I forgot about the timer counting upwards on "C" but that does at least tell you how long its been going for

[Deller12]

That's a good point Clive I'm looking forward to this build it should be the last addition

[Deller12]

No cloths this time

In my build I incorporated the safe relay start function, so if anything is switched on, when you turn the power on key nothing will happen until everything is switched off, once the unit is powered up the safety start is then bypassed with a voltage from the main board.

As the start up timer was an after thought, following THM advice I`ve used the safety start mechanism to my advantage. Operation will be Top right key switch turned on to power the timer (both these arent in the safe relay setup), set the time I want to start the board up, click the switch on for the HLT element, switch on the main unit (panic button key) at his point nothing will happen with the main board due to the safe relay start function, now for the clever bit... once the timer relay has counted down this will then supply a voltage to the safe relay thereby powering up the board automatically effectively bypassing the safe relay start function.

EDIT the red button by the side of my other timer is also a reset switch.

I just need to finish a little wiring before the grand test to make sure it works the way I want it to.

Cheers

Would you be able to give me the part number for the timer start/stop switch please ?

[barneey]

This one?

Its one of these, which will come with a NC & NO block, I have a spare blocks so can change them accordingly. I`m hoping it will be of the non latching type if not a few modifications will be needed.

Is that the one you are using with your count down timer ?

[barneey]

I`m using that for the B3S timer, the photo above show a red momentary switch, which originally was to reset the timer, however the b3s comes with a reset switch on the panel so it was needed, as previous posts you do need a start stop switch, so it was just a case of taking out the red momentary and adding the dual purpose switch.

The mechical b1s timer at the top of the box was wired with a simple on/off key switch as its simplier in design.

Cheers
