Activating bout markers on a drill with limit switches

[jd-baz]

anyone able to throw light on my problem
bought a drill lately but when it came it had a simple hydraulic diverter valve to work the bout markers with just a simple on off switch,switch on to work left and off to work right bout marker,
thought there had to be a way of making this more automatic
anyway bought a latching relay and limit switches and wired up,
but it now seems a latching relay doesent like to be ignited the whole time,i thought using the two limit switches to make the loop and when one would go down it would break the loop and in turn activate the latching relay and in turn activate the diverter valve each second time,
its working for about 30/40 seconds and will then blow the fuse in the tractor and the relay doesent want to be ignited the whole time i presume,
someone told me to try a delay relay to activate the latching relay,but a delay relay seemingly only works on a delay after its ignited.
anyone able to send me in the right direction or what i need without costing a fortune
thanks in advance

Switch on to work left = pin 87
Switch off to work right = pin 87A
This is just a standard 5 pin relay with pin 30 connected to 12Volts. Now how you control the coil (85 + 86) from the switches? How complicated are the switches you used, single on/off or 3 terminal?

Just a pair simple on off limit switch like this,

But when in left position, how do you intend to lift left and drop right? Ffor example can you position the limit switches so the latching relay only gets a pulse for example 10seconds? This would give the relay time to activate and not blow the fuse. The same for the other direction .......

Thats why I thought the latching relay was best,work right once then left next time,only activate the divertor every second time,and then I tried the timer relay working the latching relay,but the timer relay only wants a pulse to activate the timer

But you are going to have to override the limit switches to get them into the opposite position, how are you doing this. Or am I missing something? I'll read your first post again .......

Im using them to break the power going to the Switch input on the latching relay and the latching relay sends power every second time to the divertor

Yes I understand that bit, but how do you override them to go from left marker to right and from right marker to left. The previous setup was changing direction withe the simple On/Off flick switch, on= left off = right. The limit switches cant change direction for you, can they the marker arms will have to move first, no? Sorry I'm a bit slow today

Thats what the latching relay was doing,i used the two limit switches in a loop to the switch,so each time either arm came up it broke the circuit to the switch input on latching relay with made it turn on or off the diverter valve.
Only used one output out of latching relay,
So if right arm was coming up it made the circuit and it switched the latching relay which turned on the divertor to activate left arm,and when it came up it made circuit again which activated latching relay to turn off divertor then right arm worked

Can you override the limit switches at the top and bottom with the flick switch forget about the latch, does that make sense? If you think the limit switches can't drive the solenoid, we can use a relay. Just pop it in just before the solenoid.

The solenoid on the diverted valve.

explain the flick switch with the limit switches abit better

Limit switch will hold the marker in work, flick switch will override limit switch just to start travel in the opposite direction. A flick switch you hold to go right or hold to go left, with off in the middle. How does that sound?

Not to sound smart,but im trying to do away with a switch,it came with an on off switch for the divertor which would do the same as your saying without the limit switches,but i want to automate it abit,think i have it sorted with the help of another member.

No worries ........

Just stick a flip flop valve in there that will alternate each side every time
No wiring or switches to mess with
The horsch Co4 have them
