Hi all, my first post here.
I would really appreciate some help with a little project.
Components: RE11LAMW delay on relay. Spec document -
http://docs-europe.electrocomponents.com/webdocs/0d0f/0900766b80d0f587.pdf
Horizontal Float Switch:
My project:
When the float switch is off (breaks circuit) and then switches back on (re-establishes a circuit) - ie. the circuit to the relay has been interrupted, I would like the relay timer to begin counting down from the set time period. When the timer expires, I would like the relay to provide energy to a pump.
I'm pretty sure I have the correct relay, but I haven't got a clue how to wire the thing.
At the top of the relay is an A1 contact, with two more unlabelled contacts. At the bottom of the relay is an L contact (I'm pretty sure this is the "Load" contact) and also two more unlabelled contacts.
The complete cycle is as follows:
1. Float switch circuit is connected, power is provided to a pump
2. Float switch circuit is broken, power to the pump is disconnected
3. Float switch circuit is re-connected, delay-on relay begins counting down
4. Relay timer expires, power is provided to the pump
repeat the cycle.
It's probably worth noting the float switch will be mounted upside-down for this application, incase I confused somebody It's not a typical use of a float switch, its basically detecting an over-flow and pausing the pumping for a little while.
Any help would be greatly appreciated.
