EV5: the Pitt river Automatic water level controller (single, double tank control)
EV5 dual tank automatic Sheung Shui level controller through the tank's upper / lower limit level control, can achieve a single tank on / under the liquid level in Sheung Shui, single liquid level Sheung Shui, water protection / lower limit control, drainage, The Pumped control. Can also be used for joint control of the dual-tank. While with manual Sheung Shui. Applied to all kinds of Sheung Shui, drainage, pumping occasions, is the product of an industrial, residential apply.
A group AT35-3 water level sensor input, with the joint control of the upper and lower water tank (source) AT35-7.
All the way normally open and normally closed contact output

The input common-A, B, C, D, E, five level EXPLORATION pole signal input:
A is an upper limit on the tank-bit input;
B is the lower limit on tank-bit input;
C is Public extremely;
D is the lower limit position under the tank input;
E is the upper limit under the tank-bit input.
Output 1 independent one relay, normally open, normally closed contact output, control the Sheung Shui solenoid valve or pump.
Output contact current capacity for resistive load 6A, inductive load 1A (control greater than 1000W electric heating or greater than 100W of electricity
Machine or water pump, the greater the load required AC contactor expansion).
Other parameters level sensor can be long distance connection uses ordinary wire, with an effective range of 100 meters.
Wiring example diagram:
Single tank control on / under the liquid level in Sheung Shui:
Wiring as shown below: A-upper limit position, the B-lower limit, C-Public electrode (placed in the tank the bottom), CDE shorted. Control solenoid valve normally open. Energized, when the water level below the upper limit of bit A normally open contact closure, open Sheung Shui output, normally open until the water level reaches the upper limit of the liquid level A point of disconnect, stop output; When the water level is below the lower limit of B, often the open point re-closed to open Sheung water.
Single tank drainage, pumping control:
Wiring the following diagram: A, B,-NC, C-Public electrode (placed on the bottom of the tank), D-lower limit, E-ceiling spaces, normally open control output. Energized, when the water level higher than the lower limit D, open pump the water, until the water level falls below the lower limit D stop; When the water level reaches the upper limit E, and then turn to pump the water to the water level reaches the lower limit D.
Single tank water protection / lower control:
Wiring for: A, B-NC, C-public electrode (placed on the tank bottom), D - the lower limit position, E-limit position, the normally open switch point control thermostat to control the electrical heating of dry anti dry, normally closed control solenoid valve in Sheung Shui. When the water when the liquid level is below the lower limit of the bit D solenoid valve normally open points disconnected, cut off the power supply of electric heating, normally closed pull, control solenoid valve Sheung Shui; normally closed when the water level reached the upper limit E disconnect, stop Sheung Shui, normally open pull, connected to the output of electric heating.
