WATER LEVEL SWITCH
WPS 3000plus
Art.-No.: 1 11 46 20
THE WATER LEVEL SWITCH WPS 3000PLUS
for monitoring conductive liquids in tanks or wells. By adjusting
the sliding switch, the device can be configured to either refill or
discharge/empty function. In refill function a liquid level will be
maintained between two sensors (min and max). When the liquid
level reaches the MIN sensor (the lower sensor) a relay will switch
which can then activate pumps, valves or connected signals. The
advantage is, that the installation is very easy as all connections
are pluggable and ready for use. The unit is also maintenance free
as there are no movable parts such as float switches.
FEATURES
– Free selectable switching points by the positioning of the two water sensors.
– The relay output can be defined as on/off at switching point.
– Remote sensoring by two wire cable up to 20 m.
– Usable for all containers/tanks made of concrete, plastic or metal.
– No dangerous high-voltage at the water sensor.
– Automatic operation. Monitoring and maintenance free.
– Easy and quick installation as the whole configuration
has mounted connectors.
– LED indicators for power, level, error and relay.
– Sorrounding temperature: –15°C...+40°C

is ideal
LEDS:
1. LED „SENSOR MIN" ON:
The liquid has reached the level of Sensor „MIN";
2. LED „SENSOR MAX" ON:
The liquid has reached the level of Sensor „MAX";
3. LED „FEHLER" (ERROR) ON:
The precondition is a water contact of the water sensors! For example,
the water sensors are reversed and the water sensor 1 „sensor MIN" is
interrupted or not connected.
4. LED „REL. EIN" ON:
The relay is switched "ON"
MODE-SWITCH:
1. POSITION „NACHFÜLLEN" (REFILL):
The device has been configured into refill mode.
2. POSITION „ENTLEEREN" (EMPTY):
The device has been configured to empty/discharge liquid level/tank
The device can be configured to either refill a tank of liquid or to discharge/
empty the liquid level. The two drawings on page 21 show the operating
principle of the WPS 3000plus.
